Fiio FiiO BR13
The FiiO BR13 is a compact Bluetooth receiver, USB DAC and S/PDIF converter designed to add modern wireless and digital connectivity to an existing amplifier, receiver or active-speaker system. It receives audio through Bluetooth, USB-C, optical or coaxial input and outputs through stereo RCA, optical or coaxial connections. A Qualcomm QCC5125 Bluetooth platform supports LDAC and multiple aptX codecs, while the ES9018K2M DAC and TPA1882 op-amp provide a standard 2Vrms RCA line output. The BR13 is a source component only: it has no headphone amplifier, speaker amplifier, battery or network-streaming platform. Why it stands out LDAC and aptX Adaptive Bluetooth reception Bluetooth 5.2 supports LDAC, aptX Adaptive, aptX HD, aptX Low Latency, aptX and SBC from compatible phones, tablets and computers. Bluetooth, USB DAC and S/PDIF conversion Use one small component for wireless reception, computer audio, television audio and conversion between optical, coaxial and analog RCA systems. ES9018K2M DAC with 2Vrms RCA output The internal ESS DAC and TPA1882 analog stage allow direct connection to a line-level amplifier input or active speakers without requiring a separate DAC. App control, PEQ and digital routing tools FiiO Control provides Bluetooth codec settings, presets, custom PEQ, channel balance, upsampling, low-latency mode and OTA firmware updates. Best for Adding high-resolution Bluetooth reception to an older amplifier or active speakers Converting television optical or coaxial audio to RCA line output Using a computer or compatible console with a simple UAC1.0 USB DAC Routing optical and coaxial digital signals between existing audio components Not ideal for Users who need Bluetooth transmission to wireless headphones Anyone who wants Wi-Fi, AirPlay, Roon Ready or native streaming-service support Driving headphones, passive speakers or a power amplifier that requires balanced input Portable use without a continuous USB power source EMiUZEK Buying Notes The BR13 is a Bluetooth receiver, not a transmitter. It accepts audio from a phone or computer and sends it to wired audio equipment. RCA is a 2Vrms line-level output with digital volume adjustment, not a powered headphone or speaker output. A downstream amplifier or active speakers are required. FiiO Control connects only while the BR13 is in Bluetooth input mode. Saved settings such as upsampling can remain active after switching inputs, but EQ works only with Bluetooth and USB input. Digital upsampling can prevent sound from some optical or coaxial devices. If a digital output is silent or incompatible, disable upsampling or enable the appropriate compatibility setting. Frequently asked questions Can the FiiO BR13 transmit Bluetooth audio? No. It receives Bluetooth audio from a phone, tablet, television or computer. It cannot send audio to Bluetooth headphones or wireless speakers. Does the BR13 support Wi-Fi streaming? No. It has no Wi-Fi, AirPlay, Chromecast, Spotify Connect or Roon Ready function. Use Bluetooth, USB, optical or coaxial input. Can I connect headphones directly? No. It has no headphone socket or headphone amplifier. Connect RCA output to a separate headphone amplifier. Can it drive passive speakers? No. Connect it to an integrated amplifier, receiver, power amplifier with suitable input sensitivity or active speakers. Which Bluetooth codecs are supported? It supports SBC, aptX, aptX LL, aptX HD, aptX Adaptive and LDAC. Codec availability depends on the transmitting device and enabled settings. Does it support AAC? AAC is not included in FiiO's official BR13 codec list. Apple devices can connect using a mutually supported codec, normally SBC. Can two phones stay connected simultaneously? Yes. Bluetooth multipoint supports two transmitting devices. Pause playback on one before starting the other. What is the maximum Bluetooth range? FiiO states a transmission distance of up to approximately 30 metres under favourable open conditions. Walls, interference and the source device can reduce the practical range. What does low-latency mode do? It prioritizes aptX Low Latency where the transmitter also supports it, reducing delay for video and gaming. Both ends must support the codec for the benefit to apply. Can I use it as a USB DAC? Yes. USB-C supports UAC1.0 plug-and-play operation up to PCM 96kHz/24-bit with compatible computers, phones, PS5 and Nintendo Switch systems. Does the USB-C port carry both power and audio? Yes. It is a two-way USB-C power/data connection. The BR13 has no battery and requires a stable 5V/1A USB supply during operation. What are the maximum optical and coaxial input rates? Coaxial input supports up to PCM 192kHz/24-bit, while optical input supports up to PCM 96kHz/24-bit. What are the maximum digital output rates? Optical and coaxial output support up to PCM 96kHz/24-bit when using the BR13's frequency-doubling or conversion functions. Can it convert optical input to RCA output? Yes. Optical input can be decoded to RCA and can also be routed to optical or coaxial digital output. Can it convert coaxial input to optical output? Yes. In Coaxial In mode, the BR13 can provide optical and RCA output. What is optical bypass? In Optical In mode, the optical signal can pass through to Optical Out while the BR13 also supports other compatible outputs, simplifying systems that share one optical source. Can optical and coaxial outputs work simultaneously? Output availability depends on the selected input and routing mode. Optical input can provide coaxial, optical and RCA output; coaxial input provides optical and RCA output. Why is there no sound from optical or coaxial output? Confirm that the source uses supported stereo PCM, select the correct input and disable digital upsampling in FiiO Control if the receiving device cannot accept the converted rate. Does PEQ work with optical and coaxial input? No. FiiO specifies EQ support only for Bluetooth and USB input. Other saved system settings may still affect S/PDIF modes. Does upsampling improve every source? Upsampling changes the output sample rate but cannot recreate information absent from the source. Its audible benefit is system-dependent and compatibility should take priority. Can the BR13 control active-speaker volume? Yes, its 60-step digital volume can adjust RCA output. Begin at a low level, especially when connecting directly to active speakers. Is the BR13 the same kind of product as the FiiO SR11? No. BR13 focuses on Bluetooth reception, USB DAC and S/PDIF conversion with analog RCA output. SR11 is a Wi-Fi/Ethernet digital streaming transport with Roon Ready and AirPlay but no analog output.

Best for One-box desktop headphone and network-streaming systems Users switching between sensitive IEMs and demanding balanced headphones Active-speaker or amplifier systems needing RCA and balanced XLR output Systems combining digital sources, network playback and analog line inputs Not ideal for Users who need HDMI ARC for direct television control Users who want Android streaming apps installed directly on the device Portable or battery-powered listening Driving passive speakers without an external amplifier EMiUZEK Buying Notes K15 has no HDMI ARC. Connect a television through optical or coaxial output and set the TV to a supported two-channel PCM format. The 10-band PEQ does not process RCA line input or 4.4mm balanced analog input. K17 is the more suitable model when 31-band PEQ and broader processing are required. AirPlay is AirPlay 1 and is limited to 44.1kHz. Network streaming supports AirPlay and Roon Ready reception; K15 is not an Android player for installing arbitrary apps. The quoted 3000mW + 3000mW output applies to the balanced headphone outputs at 32Ω in Ultra High Gain. Use lower gain and low starting volume with sensitive earphones. FAQ Should I choose FiiO K15, K13 R2R or K17? Choose K15 when network streaming, analog inputs, balanced XLR line output and strong headphone power are needed at a lower price than K17. Choose K13 R2R when a smaller unit and resistor-ladder NOS/OS sound are more important than streaming and analog inputs. Choose K17 when you need the higher-grade AK4191 plus dual AK4499EX DAC architecture, more power, 31-band PEQ, digital outputs, trigger input and the additional system features omitted from K15. Can K15 play music without a computer? Yes. It can receive AirPlay or Roon Ready playback over Wi-Fi or Ethernet and can scan music from compatible USB storage through the rear USB-A port. It does not run general Android streaming apps directly. Does K15 support Spotify Connect, TIDAL Connect or Chromecast? FIIO officially specifies AirPlay and Roon Ready for network streaming. Do not assume native Spotify Connect, TIDAL Connect or Chromecast support unless FIIO adds it in current firmware. Those services can still be used through a compatible Roon setup, AirPlay source or separately connected streamer. What is the AirPlay limitation? K15 uses AirPlay 1 and supports up to 44.1kHz through that route. For higher-resolution network playback, use compatible Roon Ready or local playback instead of assuming AirPlay transmits the original high-resolution file unchanged. Can I connect a television through HDMI ARC? No. K15 has no HDMI input or HDMI ARC. Use optical or coaxial digital input from the television and select two-channel PCM in the TV audio settings. Dolby or bitstream output may produce no sound. Does PEQ work with every input? No. K15 provides 10-band PEQ for supported digital paths, but FIIO states that RCA line input and 4.4mm balanced analog input do not receive PEQ processing. PEQ is adjusted through the supported FIIO web workflow and control connection; it is not the 31-band system used by K17. Can it drive sensitive IEMs as well as full-size headphones? Yes. Five gain levels allow lower hardware gain for sensitive earphones and Super High or Ultra High Gain for demanding models. Begin with Low gain and minimum volume when changing headphones. The maximum rating is not the correct operating target for every headphone. Can I connect more than one headphone at the same time? The front 6.35mm, 4.4mm and XLR4 outputs share the same output priority and can operate together, but FIIO does not recommend long simultaneous use—especially with headphones of very different impedance. One headphone at a time is safer and easier to control. Can K15 power passive speakers? No. RCA and XLR are line or preamplifier outputs. Connect them to active speakers, an integrated amplifier or a separate power amplifier. Passive speakers cannot be connected directly. When should I use LO, PRE, PO or PO+PRE? Use PO for the front headphone outputs. Use LO when sending a fixed-level signal to another amplifier or preamplifier. Use PRE when the K15 volume knob should control rear RCA or XLR output. PO+PRE activates front and rear variable outputs together, so check all connected equipment before raising volume. Can I connect a turntable? Only when the turntable has a built-in phono preamplifier or an external phono stage is placed before K15. The RCA input is line level and is not a phono input. Analog inputs also bypass the K15 PEQ. Can I connect a USB hard drive for local playback? The rear USB-A port supplies up to 500mA and is intended primarily for USB flash storage. A portable hard drive that requires more current should use its own external power supply. Does Windows require a USB driver? Windows requires FIIO’s USB DAC driver for normal high-rate UAC 2.0 operation. macOS is driver-free. UAC 1.0 mode improves compatibility with devices such as PS5 and Nintendo Switch but supports fewer formats. Can I use an external linear power supply? Yes. K15 supports either its internal universal AC power supply or a compatible external 12V/at least 2.5A DC supply. Use only one power source at a time and verify polarity and specifications before connection.

Fiio FiiO K11 R2R
FiiO K11 R2R is a compact desktop DAC and headphone amplifier for listeners who specifically want an affordable resistor-ladder design rather than the more conventional delta-sigma architecture used in the standard K11. Its four-channel fully differential 24-bit R2R network uses 192 precision thin-film resistors and offers selectable NOS and OS playback. USB-C, optical and coaxial inputs cover common desktop and television sources, while 6.35mm and 4.4mm headphone outputs plus RCA line and preamplifier modes allow it to serve both headphones and a stereo system.Why it stands out Affordable true R2R conversion FIIO’s four-channel fully differential 24-bit resistor ladder uses 192 precision thin-film resistors, making the K11 R2R a practical entry point for listeners who want to try R2R conversion without buying a separate high-priced DAC. NOS and OS modes with clearly different purposes NOS sends the signal through the ladder without digital oversampling, while OS upsamples to 384kHz before conversion. The two modes let you compare a more direct R2R presentation with a cleaner, more controlled alternative. Useful power across balanced and single-ended headphones The 4.4mm balanced output reaches up to 1300mW + 1300mW at 32Ω, while the 6.35mm output, three gain levels and electronic volume control support a wider range of full-size headphones and earphones. Compact DAC, headphone amplifier and preamplifier in one Use USB-C, optical or coaxial input, listen through headphones, or switch the RCA output between fixed line level and variable preamplifier mode for an external amplifier or active speakers.Best for Listeners who specifically want to try R2R and compare NOS with OS playback Compact PC or Mac headphone systems using USB-C Television headphone systems using optical PCM output Users who want one desktop unit for both headphones and RCA-equipped stereo systems Not ideal for Users who want Bluetooth reception or wireless-headphone transmission Turntables, cassette decks or other sources that require an analog input Systems that require balanced XLR line output Users seeking the lowest measured distortion and noise rather than the R2R presentation Portable use or direct connection to passive speakers EMiUZEK Buying Notes K11 R2R and the standard K11 are different sound and feature choices, not simple old and new versions. Choose the R2R model for its resistor ladder and NOS/OS modes; choose the standard K11 if conventional delta-sigma conversion and stronger measured noise and distortion performance matter more. There is no Bluetooth or analog input. Phones and computers need USB audio, while televisions and digital transports need compatible optical or coaxial output. The highest quoted 1300mW + 1300mW power is from the 4.4mm balanced output at 32Ω. The 6.35mm output has different power figures, so do not compare them as if they were identical. For very sensitive earphones, begin with low gain and low volume. Buyers who prioritize the lowest possible noise floor should compare the standard K11 before ordering. The rear RCA sockets can provide fixed line output or variable preamplifier output, but there is no balanced XLR line output and passive speakers still require a separate amplifier. FAQ Should I buy the K11 R2R or the standard K11? Choose K11 R2R if the resistor-ladder design, fuller vocal presentation and the ability to switch between NOS and OS are the main reasons for buying. The standard K11 uses a conventional delta-sigma DAC, offers digital-filter choices and has better measured distortion and noise performance. The R2R version is an alternative tuning and architecture, not an automatic upgrade in every area. What actually changes when I switch between NOS and OS? NOS avoids digital oversampling and preserves the direct R2R conversion path; many listeners choose it for a denser, more relaxed presentation. OS upsamples to 384kHz before conversion and generally presents edges and detail more cleanly. The setting does not increase amplifier power, and the preferred mode depends on the headphones and recording. Will it drive my headphones, and do I need a 4.4mm cable? A 6.35mm headphone can be used normally and does not need to be recabled. The 4.4mm balanced output provides the highest power—up to 1300mW + 1300mW at 32Ω—and is useful for compatible, less sensitive headphones. Choose low, medium or high gain according to headphone sensitivity and start with the volume low. Is the K11 R2R suitable for sensitive IEMs? It can be used with IEMs through the 6.35mm output and low gain, but the R2R model does not have the lowest noise figures in the K11 family. Extremely sensitive earphones may reveal more background noise than less sensitive headphones; buyers who consider silence between tracks the top priority should compare the standard K11. Can I use it with active speakers or an existing amplifier? Yes. Connect the rear RCA output to an amplifier or active speakers. Use LO for a fixed-level signal when another device controls volume, or PRE when you want the K11 R2R knob to control the output level. It has no XLR line output and cannot power passive speakers directly. Can I connect a television? Yes, through optical input when the television can output two-channel PCM. If there is no sound, change the TV’s digital-audio setting from Dolby or bitstream to PCM. The K11 R2R does not include HDMI ARC. Does it support Bluetooth or analog input? No. It has no Bluetooth receiver, Bluetooth transmitter or analog audio input. Available sources are USB-C, optical and coaxial digital audio. Can the coaxial socket work as a digital output? Yes, but only when USB is selected as the input. It is not a general-purpose digital pass-through for optical or coaxial input sources. Does it need a driver on Windows, Mac or a game console? Mac computers normally use USB Audio without an additional driver. Windows users may need FIIO’s USB driver for the highest sample rates and native DSD. UAC 1.0 mode improves compatibility with devices that do not support UAC 2.0, although the available formats may be reduced.HOW TO CONNECT Computer and wired headphones Source icon: ComputerSource: PC / MacConnection: USB-COutput connection: Headphone outputTarget icon: HeadphonesOutput: 6.35mm / 4.4mm Note: Select USB input, choose low, medium or high gain for the headphones, and begin with the volume low.

Fiio FiiO TT13
The FiiO TT13 is a fully automatic belt-drive turntable designed for straightforward vinyl playback. Press Start and the tonearm lifts, moves into position and begins playing; at the end, it can stop and return automatically. Repeat playback and remote control make it especially convenient for everyday listening. A built-in phono preamplifier provides fixed RCA line output for direct connection to active speakers or a line-level amplifier input. The Bluetooth version can also transmit vinyl audio wirelessly to compatible headphones or speakers, while the Standard version is intended for wired RCA listening. Why it stands out Fully automatic playback with repeat Automatic start, stop, tonearm return and loop playback reduce handling and make vinyl easier to use without manually cueing every side. Built-in analog phono preamplifier Dual JRC5532 op-amps provide an RCA line-level output up to 800mV, allowing direct connection to active speakers or a standard line input. Audio-Technica AT3600LA cartridge The fitted moving-magnet cartridge is widely supported, with a replaceable stylus and factory-optimized tracking force for the automatic tonearm. Optional aptX HD Bluetooth transmission The Bluetooth version uses a Qualcomm QCC3040 platform and supports SBC, aptX, aptX Low Latency and aptX HD transmission. Best for First-time vinyl listeners who want automatic, low-effort operation Direct connection to active speakers or an amplifier's AUX/LINE input Users who value remote start, stop, repeat and tonearm control Wireless listening through compatible Bluetooth headphones or speakers when choosing the Bluetooth version Not ideal for Users who want adjustable tracking force, anti-skate or broad cartridge experimentation Systems that require a raw PHONO-level output for an external phono stage Anyone who wants to digitize records through USB Buyers expecting Bluetooth transmission from the Standard version EMiUZEK Buying Notes Choose the variant carefully: only the Bluetooth version can transmit audio wirelessly. Color and regional power-plug options are separate variant selections. The TT13 provides fixed RCA LINE output only, not switchable PHONO output. Connect it to AUX, LINE, CD or another line-level input—not to a phono input. The automatic mechanism is calibrated for the supplied Audio-Technica AT3600LA cartridge at 3.5 ± 0.5g. FiiO recommends replacing it only with the same cartridge model. Place the turntable on a level, stable surface away from speakers and vibration. Confirm the correct 7/12-inch size and 33⅓/45 RPM settings before playback. Frequently asked questions Do all FiiO TT13 versions include Bluetooth? No. Bluetooth transmission is available only on variants labelled Bluetooth. The Standard version uses wired RCA output only. Is Bluetooth an input or an output? It is an output. The Bluetooth version transmits record playback to compatible headphones, speakers or receivers; it does not receive music from a phone. Which Bluetooth codecs are supported? The Bluetooth 5.2 version supports SBC, aptX, aptX Low Latency and aptX HD. The receiving device must support the same codec, otherwise the connection falls back to a mutually supported format. Does Bluetooth preserve a completely analog signal path? No. RCA playback follows the analog signal path, while Bluetooth transmission requires analog-to-digital conversion and wireless encoding. Do I need a separate phono preamp? No. The built-in phono stage outputs line level. Connect RCA directly to active speakers or a LINE/AUX input. Can I connect the TT13 to a PHONO input? It is not recommended because the TT13 does not provide raw phono-level output. Feeding its line-level signal into another phono stage can cause excessive gain and incorrect equalization. Can it drive passive speakers directly? No. Passive speakers require an integrated amplifier or power amplifier. The TT13 can connect directly only to active speakers or line-level equipment. Can I connect wired headphones directly? No. There is no headphone output. Use a headphone amplifier with RCA input, or choose the Bluetooth version for compatible wireless headphones. Is the TT13 fully automatic? Yes. It supports automatic start, stop, tonearm movement and return, plus repeat playback. Manual cueing is also possible when needed. Which record sizes and speeds are supported? It supports 7-inch and 12-inch records at 33⅓ or 45 RPM. A large-hole 45 RPM adapter is included. Can it play 10-inch records? The automatic size selector is specified for 7-inch and 12-inch records. A 10-inch record may require careful manual cueing and is not part of the stated automatic-size support. Can I install a different cartridge? FiiO recommends only the same AT3600LA model because the automatic tonearm and tracking force are factory-calibrated for it. Other cartridges are not supported. Can I replace only the stylus? Yes. The stylus is a consumable part and can be replaced with a compatible stylus for the AT3600LA cartridge. Stylus wear is not covered by the product warranty. Can tracking force and anti-skate be adjusted? No user adjustment is provided. Tracking force is factory-set to approximately 3.5 ± 0.5g for the supplied cartridge. Can the TT13 convert records to digital files? No. It does not include USB recording or vinyl-ripping functionality. Why does the platter appear to wobble slightly? First confirm that the cast-aluminum platter is seated correctly and rotates freely. If movement is excessive or audible, stop playback and reseat the platter rather than forcing the mechanism. What does the rear balance control do? It compensates for small left/right level differences in the analog output. Leave it centred unless one channel is consistently louder after checking the cables and speakers. Can I use an external DC power supply? Yes. Use a suitable 12V/1A or higher supply and turn off the AC power switch when using DC. If AC and DC are connected together, AC takes priority. Does the dust cover need to be removed during playback? No. It can be used open or closed and is removable. If acoustic feedback occurs at high speaker volume, try closing it, removing it or moving the turntable farther from the speakers.

Fiio FiiO K19
The FiiO K19 is a flagship desktop DAC, headphone amplifier and preamplifier built for demanding headphones, active speakers and full-size stereo systems. Dual ES9039SPRO DACs, an eight-channel THX AAA 788+ amplifier and a fully balanced signal path provide substantial output power with flexible source and output control. USB, optical, coaxial, HDMI, HDMI ARC and Bluetooth inputs allow the K19 to serve computers, televisions, streamers and mobile devices. Its slim chassis can sit flat or vertically on the supplied stand, while 31-band PEQ provides unusually detailed system and headphone tuning. Why it stands out Dual ES9039SPRO flagship DAC architecture Two eight-channel ESS DACs operate in a fully balanced design, supported by dual ACCUSILICON femtosecond oscillators and dedicated FPGA clock management. Eight-channel THX AAA 788+ headphone amplifier The balanced 4.4mm and XLR4 outputs deliver up to 8000mW + 8000mW at 32Ω in Ultra High Gain for demanding dynamic and planar-magnetic headphones. HDMI input, HDMI pass-through and HDMI ARC Use the K19 with a computer, game source, monitor or compatible television, in addition to conventional USB, optical, coaxial and Bluetooth audio sources. 31-band lossless PEQ and flexible system control Fine-tune headphones or speakers with adjustable PEQ, custom presets and DSP tools through compatible desktop software, web control or the FiiO Control app. Best for Flagship desktop headphone systems requiring high balanced output power Users who want one DAC for a computer, television and multiple digital sources Balanced stereo systems using XLR preamplifier or fixed line output Listeners who need detailed PEQ correction for headphones or room integration Not ideal for Portable or battery-powered listening Driving passive speakers without a separate power amplifier Very small desks where a 250 × 225mm component is impractical Users who need analog audio input, network streaming or phono input built into the DAC EMiUZEK Buying Notes The K19 is powerful enough to damage sensitive earphones or hearing at unsafe settings. Begin with Low Gain and low volume, then increase only as required. Choose the correct rear power selector for the connected supply: AC for the regional mains cable or DC for a compatible 10–16V supply; FiiO recommends 15V/3A or higher. Never connect an external DC supply outside the specified range. LO is fixed-level rear output and cannot be volume-controlled. Lower the downstream amplifier or active-speaker volume before selecting LO; use PRE when the K19 should control volume. HDMI ARC supports 44.1/48kHz PCM and depends on the television's ARC settings. It is not eARC multichannel decoding; set the TV to a compatible PCM output. Frequently asked questions What is the maximum balanced headphone output? In Ultra High Gain, the 4.4mm and XLR4 outputs provide at least 8000mW + 8000mW at 32Ω and 1100mW + 1100mW at 300Ω under FiiO's stated test conditions. Can I use sensitive IEMs with the K19? Yes, but its very high power requires care. Select Low Gain, set a low maximum-volume limit and start playback at minimum volume. Can it power passive speakers directly? No. RCA or XLR output must feed an external power amplifier, integrated amplifier or active speakers. What is the difference between PO, PRE, LO and PO+PRE? PO sends adjustable audio to the front headphone outputs. PRE sends adjustable audio to the rear RCA/XLR outputs. LO sends fixed-level audio to the rear outputs. PO+PRE activates both front and rear adjustable outputs. Can the three front headphone outputs work simultaneously? They share the same priority and can output together, but FiiO does not recommend prolonged simultaneous use, especially with headphones of very different impedance. Does HDMI ARC work with every television? The TV must support ARC and be configured for HDMI ARC audio, normally PCM. HDMI compatibility varies by source and display, so confirm the TV's ARC settings if no audio is received. What is the difference between HDMI IN and HDMI ARC? HDMI IN receives audio and video from a source and passes video to a monitor through HDMI OUT. HDMI ARC receives compatible audio back from a television through the HDMI OUT (ARC) port. Does the K19 support multichannel Dolby or DTS decoding? It is a two-channel audio DAC and is not documented as a Dolby/DTS surround decoder. Configure the HDMI source or TV to output compatible stereo PCM. Can I control TV volume with HDMI CEC? FiiO does not specify full HDMI-CEC power and volume integration. Use the K19 knob, supplied remote or FiiO Control, and do not assume the TV remote will control every function. What does the 31-band PEQ support? It can adjust PCM signals from 44.1kHz to 192kHz without sample-rate conversion, with per-band gain and Q controls plus importable and exportable presets. Can I use PEQ with every format and input? PEQ availability depends on input, format, sample rate and firmware. Native DSD and signals outside the supported PCM range may not use the same processing path. Does the K19 have analog inputs? No. Its inputs are USB, coaxial, optical, HDMI, HDMI ARC and Bluetooth. RCA and XLR connectors on the rear panel are outputs. Which Bluetooth codecs are supported? Bluetooth 5.1 reception supports SBC, AAC, aptX, aptX LL, aptX HD, aptX Adaptive and LDAC when the source device supports the same codec. What is the maximum USB decoding rate? USB supports up to PCM 768kHz/32-bit and native DSD512 with compatible software, drivers and source material. Does Windows require a driver? Use the current FiiO USB driver on Windows 10 or 11 for full UAC2.0 capability. FiiO states that the K19 driver is not compatible with Windows 7 or 8. Can it work with a PS5 or Nintendo Switch? The K19 supports UAC1.0 driverless mode for compatible consoles. Select UAC1.0 when the source does not support its higher-rate UAC2.0 mode. Can I connect a phone by USB?

Fiio FiiO S15
FiiO S15 is a full-width Android music streamer, DAC, digital transport and preamplifier designed to become the source component in a living-room stereo system. It plays streaming apps, network libraries and local storage, accepts external digital sources, and sends analog audio through RCA or balanced XLR to active speakers or an amplifier. The S15 combines Android 12, a Snapdragon 660 processor, AK4191 plus AK4499EX conversion, HDMI input and ARC, extensive digital input and output, removable M.2 NVMe storage and a 7.84-inch landscape touchscreen. It has no headphone amplifier and no analog input. Why it stands out Full-width Android streaming centre Install compatible Android music apps, use Pure Music mode, play from NAS and cloud libraries, or receive AirPlay, DLNA, Roon Ready and Bluetooth audio from a 430mm component designed for a standard hi-fi rack. Flagship AKM DAC and balanced preamplifier AK4191 digital processing and AK4499EX conversion feed a fully balanced analog stage with fixed or variable RCA and XLR output for active speakers, integrated amplifiers and power amplifiers. HDMI, ARC and extensive digital routing HDMI input, HDMI ARC, USB, optical, coaxial and AES inputs cover computers, televisions and digital sources, while USB, optical, coaxial, AES and HDMI I2S outputs support external DACs. Internal, removable and network storage options Use internal storage, a microSD card, USB storage, NAS services or an optional M.2 NVMe SSD in the included removable cage for a large local library. Best for Full-size stereo systems needing streaming, DAC and preamplifier functions Users who want Android apps together with HDMI ARC and local music storage Power amplifiers or active speakers with RCA or balanced XLR input Digital systems requiring AES, optical, coaxial, USB or HDMI I2S output Not ideal for Direct headphone listening because there is no headphone output Turntables, cassette decks or other sources requiring an analog input Driving passive speakers without an integrated or power amplifier Small desks or portable systems due to its 430mm width and 5.6kg weight EMiUZEK Buying Notes S15 has no headphone output. The rear 3.5mm socket is a 12V Trigger Out connection and must not be treated as a headphone jack. S15 has no analog input. A turntable requires a phono stage plus a separate analog-to-digital route, or should be connected directly to the downstream amplifier instead. The rear voltage selector must match the local AC supply before power-on. Confirm whether the unit is set for 110–120V or 220–240V. An M.2 SSD is not listed as included. The supplied cage supports compatible NVMe drives up to 2TB in 2230, 2242, 2260 and 2280 sizes. FAQ Can I connect headphones directly to the FiiO S15? No. S15 does not contain a headphone amplifier or headphone output. Connect its RCA or XLR output to a separate headphone amplifier, or use a compatible external DAC/headphone amplifier through one of the digital outputs. The rear 3.5mm socket is Trigger Out, not audio. Can S15 power passive speakers? No. RCA and XLR provide line or variable preamplifier signals only. Passive speakers require an integrated amplifier or power amplifier. Active speakers can connect directly when their input sensitivity and volume arrangement are appropriate. Can I install Spotify, TIDAL, Qobuz or Apple Music? S15 runs a customized Android 12 system and supports installation of compatible third-party applications. App availability, login methods, high-resolution support and Connect-style remote control can change with the application and firmware, so confirm the current app version rather than assuming every service behaves identically. How does S15 differ from compact streamers such as Eversolo DMP-A6 Gen 2? S15 is a full-width 430mm component and emphasizes extensive routing: HDMI input plus ARC, AES input and output, Bluetooth transmit and receive, removable M.2 cage and a flagship AKM DAC combination. Compact rivals may take less rack space and can offer a different app experience. Choose according to the connections and control workflow you will actually use, not the number of features alone. What is the difference between HDMI IN and HDMI ARC? HDMI IN accepts audio and video from a computer, disc player or set-top box and passes video to the HDMI output while S15 decodes the audio. HDMI ARC receives return audio from a compatible television through the HDMI OUT/ARC socket. ARC supports 44.1 or 48kHz, while HDMI input and output support up to 192kHz/24-bit. Can I use S15 with a turntable? Not directly. S15 has no phono or line-level analog input. Connect the turntable and phono stage to the downstream integrated amplifier, or use a separate analog-to-digital converter if the source must enter the S15 digitally. Is the M.2 SSD included? No SSD is listed in the standard package. FIIO includes the removable M.2 cage, its USB 3.0 data cable and an installation screwdriver. The cage supports compatible NVMe drives in 2230, 2242, 2260 and 2280 sizes up to 2TB. Which other storage sources can it use? S15 provides 64GB internal storage with approximately 46GB available, a microSD slot with theoretical support up to 2TB, USB-A storage connections and access to compatible network libraries through protocols including UPnP, SMB and WebDAV. Can it receive and transmit Bluetooth? Yes. Bluetooth reception supports SBC, AAC, aptX, aptX Low Latency, aptX HD, aptX Adaptive and LDAC. Bluetooth transmission supports SBC, AAC, aptX, aptX HD, LDAC and LHDC with compatible headphones or speakers. Bluetooth transmission is digital output and can mute other outputs according to the S15 priority rules. Can I use an external DAC? Yes. Digital output is available through USB, optical, coaxial, AES and HDMI I2S. HDMI I2S uses connector hardware that resembles HDMI but carries I2S audio and is not a normal HDMI connection; confirm the downstream DAC pin configuration before use. Why did the RCA and XLR outputs become silent after enabling I2S? FIIO states that enabling I2S output mutes the analog RCA and XLR outputs. Disable I2S when returning to the internal DAC and analog outputs. USB output and Bluetooth transmission also take high priority and can disable other outputs. Should I use fixed line output or preamplifier output? Use fixed line output when an integrated amplifier, preamplifier or active speaker controls volume. Use variable preamplifier output when S15 should control system volume. Before changing modes, reduce volume and confirm which device is responsible for level control to avoid an unexpectedly loud signal. Does it work with Roon, AirPlay and DLNA? FIIO lists Roon Ready, AirPlay and DLNA operating modes. Keep firmware current and connect the controller, server and S15 to the same network. Service certification and behaviour can change, so verify current firmware if a particular ecosystem is essential. Can S15 work as a USB DAC for a computer? Yes, through the front USB-C DAC port. Windows requires the FIIO USB DAC driver for full operation, while macOS is normally driver-free. USB DAC decoding supports up to PCM 768kHz/32-bit and native DSD512 under compatible settings. What should I know before connecting the S15 to mains power? Unlike an auto-ranging supply, S15 uses a rear 115V/230V selection switch. Set it to the correct local mains range before connecting power. Using the wrong setting can prevent operation or damage equipment. Is the FIIO Control app the only way to operate it? No. The front touchscreen and knobs provide direct control, and the included RM3 Bluetooth remote supports playback and volume functions after pairing. FIIO Link control differs by platform: Android supports Wi-Fi and Bluetooth control, while iOS support is more limited.

Fiio FiiO K13 R2R
FiiO K13 R2R combines a true 24-bit R2R DAC, powerful balanced headphone amplification, Bluetooth reception, PEQ, and preamplifier functionality in one versatile desktop audio center. FiiO’s proprietary four-channel R2R DAC uses 192 precision thin-film resistors with 0.1% accuracy and 30ppm low temperature drift, delivering a rich, natural, and musical presentation. Why it stands out True 24-bit R2R conversion FIIO’s four-channel fully differential resistor-ladder DAC uses 192 precision thin-film resistors, giving listeners a genuine R2R alternative to conventional delta-sigma desktop DACs. NOS and OS playback modes Switch between non-oversampling and oversampling playback instead of being locked into one presentation. NOS prioritizes the direct R2R signal path, while OS applies digital oversampling for a different response. Strong balanced headphone amplification The 4.4mm balanced output delivers up to 2400mW + 2400mW at 32Ω in high gain, while the 6.35mm output supports conventional single-ended headphones. One hub for digital sources and stereo systems Connect computers, phones, televisions and digital transports through USB-C, Bluetooth 5.4, optical or coaxial input, then listen through headphones or feed an amplifier or active speakers through RCA or balanced XLR.Best for Desktop R2R listening with headphones Balanced stereo systems requiring XLR output Users who want Bluetooth plus USB and S/PDIF inputs Not ideal for Portable or battery-powered listening Users requiring analog audio input Driving passive speakers directly EMiUZEK Buying Notes K13 R2R accepts digital sources only; it has no RCA or XLR analog input for a turntable, cassette deck or other analog source. Bluetooth works as a receiver for audio from a phone, tablet or computer. It does not transmit audio to Bluetooth headphones or speakers. RCA and XLR are line or preamplifier outputs for an amplifier or active speakers; they cannot power passive speakers directly. The quoted 2400mW + 2400mW output is for the 4.4mm balanced connection at 32Ω in high gain. Start with low volume and choose gain according to the headphones being used. FAQ How should I choose between NOS and OS mode? NOS plays through the R2R ladder without digital oversampling and is the mode to try when you want the most direct R2R presentation. OS applies oversampling and may suit listeners who prefer a smoother, more controlled presentation. Neither mode is universally better, so you can switch between them without changing the rest of the system. Do I need a balanced headphone cable to use the K13 R2R? No. Headphones with a standard 6.35mm plug can use the single-ended output. The 4.4mm connection is for headphones wired for balanced operation and is required to access the highest quoted output power. Do not connect a single-ended plug through an unsafe balanced adapter. Can the K13 R2R be used with an amplifier or active speakers? Yes. Use the RCA output for a conventional stereo connection or XLR for a balanced connection. Select the appropriate line or preamplifier mode for the receiving equipment. Passive speakers still need a separate amplifier because the K13 R2R is not a speaker power amplifier. What sources can I connect, and what does Bluetooth not do? Computers and compatible phones can use USB-C; televisions and digital transports can use optical or coaxial output; phones, tablets and computers can stream to the unit through Bluetooth 5.4 with SBC, AAC or LDAC. Bluetooth is receive-only, and there is no analog audio input.HOW TO CONNECT Computer and wired headphones Source icon: ComputerSource: PC / MacConnection: USB-COutput connection: Headphone outputTarget icon: HeadphonesOutput: 6.35mm / 4.4mm Note: Select USB input, choose a suitable gain level and begin with the volume low.

Fiio FiiO SR11
The FiiO SR11 is a compact digital streaming transport that adds network playback to an existing DAC, integrated amplifier or active speaker system with a compatible digital input. It receives music over Ethernet, Wi-Fi, AirPlay, Roon, Bluetooth or local USB storage, then sends a digital signal through USB, optical or coaxial output. The SR11 does not contain an analog DAC stage, headphone amplifier or speaker amplifier. Its purpose is to preserve your existing audio system while adding convenient streaming control and high-resolution digital transport capability. Why it stands out Roon Ready and AirPlay in one compact transport Use dedicated Roon Ready or AirPlay modes, or select MIX mode so the SR11 can remain available to either ecosystem without repeatedly changing the operating mode. USB, optical and coaxial digital outputs Connect modern USB DACs through USB-A or USB-C, or use optical and coaxial S/PDIF with traditional DACs, amplifiers and active speakers. Gigabit Ethernet and dual-band Wi-Fi A 1000Mbps Ethernet port supports stable wired streaming, while 2.4GHz and 5GHz Wi-Fi provide flexible placement when a network cable is impractical. Useful front-panel control and included remote The LCD shows operating mode, output, network status, volume and sample-rate information, while the supplied infrared remote controls key functions from the listening position. Best for Adding Roon Ready or AirPlay streaming to an existing external DAC Hi-Fi systems that already provide optical, coaxial or USB digital input Listeners who prefer a dedicated network transport instead of using a computer Compact desktop or two-channel systems that benefit from Ethernet and Wi-Fi Not ideal for Users who need analog RCA or XLR outputs Anyone expecting to connect headphones or passive speakers directly Buyers who need Spotify Connect, TIDAL Connect or Chromecast as a guaranteed native endpoint AirPlay users expecting native high-resolution output above 44.1kHz/16-bit EMiUZEK Buying Notes The SR11 is a digital transport only. Your system must include a separate DAC or a component with a compatible USB, optical or coaxial digital input. Update the unit to current firmware before setup. Firmware V630 adds Bluetooth Receive, local USB playback, DLNA, FiiO Link and OTA functions; some features are unavailable on older firmware. USB and S/PDIF output cannot operate at the same time. In S/PDIF mode, optical and coaxial output operate simultaneously; the USB-A and USB-C audio outputs also cannot feed two DACs simultaneously. AirPlay converts incoming audio to 44.1kHz/16-bit. Choose Roon over USB when the connected DAC and source library require the SR11's highest supported resolution. Frequently asked questions Does the FiiO SR11 contain a DAC? No. The SR11 outputs digital audio only. Connect it to an external DAC, an amplifier with a digital input or active speakers with compatible digital decoding. Can I connect headphones directly? No. It has no headphone output or headphone amplifier. A separate DAC/headphone amplifier is required. Can it connect directly to passive speakers? No. Passive speakers require an amplifier. The SR11 should feed a DAC or an amplifier that accepts one of its digital outputs. Does it support Roon Ready? Yes. In Roon mode, the SR11 appears as a Roon Ready endpoint on the same network. Roon over USB supports up to PCM 768kHz/32-bit and DSD256 DoP when the connected DAC supports those formats. What is MIX mode? MIX mode keeps both Roon Ready and AirPlay reception available. They cannot play simultaneously; only one sending device can use the SR11 at a time. Does AirPlay provide high-resolution output? No. FiiO specifies that PCM, DSD and MQA sources received through AirPlay are converted to 44.1kHz/16-bit before output. Does the SR11 support AirPlay 2? FiiO documents the feature as AirPlay rather than guaranteeing AirPlay 2. Treat it as an AirPlay receiver and do not purchase it specifically for AirPlay 2 multiroom functionality. Does it support Spotify Connect, TIDAL Connect or Chromecast? These are not listed by FiiO as native SR11 endpoint modes. They may be accessible through another supported ecosystem or casting method, but should not be assumed to work as dedicated native Connect endpoints. Can it receive Bluetooth audio? Yes, after updating to V630 firmware or later. Bluetooth Receive supports SBC, AAC and LDAC, then sends the received audio to the selected digital output. Can it play music from a USB flash drive? Yes, with V630 firmware or later and the latest FiiO Control app. Both USB-A and USB-C data ports support storage, but two drives cannot be used at the same time. Which local file formats are supported? FiiO lists AAC, AIF, AIFF, APE, M4A, DSF, DFF, FLAC, MP3, WAV and WMA. OGG and CUE splitting are not supported for local playback. Can USB and coaxial output play at the same time? No. Select either USB output or S/PDIF output. When S/PDIF is selected, optical and coaxial outputs operate simultaneously. Can USB-A and USB-C feed two DACs simultaneously? No. Both ports can connect to an external USB DAC, but only one USB audio output is active; by default, the first connected compatible device is used. Which output provides the highest resolution? USB supports the highest specified Roon rate, up to PCM 768kHz/32-bit and DSD256 DoP. Optical and coaxial support up to PCM 192kHz/24-bit and DSD64. Should I use Ethernet or Wi-Fi? Both are supported. Gigabit Ethernet is preferable when maximum network stability is important; dual-band Wi-Fi is convenient when cabling is difficult. Does it have a battery? No. The SR11 requires continuous 5V/2A power through its dedicated USB-C power input. Can I use a different power supply? Use a stable 5V/2A USB power supply that meets FiiO's requirement. Higher-voltage fast-charging output is unnecessary because the SR11 is specified for 5V input. Why is there no sound after connection? Confirm that the source and SR11 are on the same network, select the correct receiving mode, then match the SR11 output setting to the connected DAC. USB and S/PDIF modes are selected separately. How is firmware updated? Firmware can be installed from a USB flash drive through the USB-A or USB-C data port. Later firmware also supports OTA updating where available.

Fiio FiiO BTR13
FiiO BTR13 is a compact rechargeable Bluetooth receiver, USB DAC and headphone amplifier designed to add wireless playback and digital audio to wired earphones and headphones. Its physical BT/PC/PHONE switch changes both the connection method and power behaviour without requiring menu navigation. Dual CS43131 DACs, 3.5mm single-ended and 4.4mm balanced outputs, global PEQ and a colour display make it the entry-level all-rounder in FIIO’s BTR range. It is best matched with IEMs and portable headphones rather than very demanding full-size models. Why it stands out Bluetooth receiver and USB DAC in one pocket device Receive SBC, AAC, aptX, aptX Low Latency, aptX HD, aptX Adaptive or LDAC from compatible Bluetooth sources, or connect by USB-C for driver-free PCM playback up to 96kHz/24-bit. Physical BT, PC and PHONE mode switch BT mode receives wireless audio, PC mode uses USB audio and USB power, and PHONE mode uses USB audio while normally preventing the BTR13 from drawing charging power from the phone. Dual outputs with useful portable power The 3.5mm output provides up to 100mW + 100mW at 32Ω, while the 4.4mm balanced output reaches up to 220mW + 220mW for compatible earphones and headphones. Global PEQ, colour display and CTIA controls The 0.96-inch colour screen shows operating information, while FIIO Control and compatible web control provide PEQ adjustment. The 3.5mm socket also supports compatible CTIA in-line controls and microphones. Best for Using wired IEMs or portable headphones wirelessly with a phone Switching between Bluetooth, phone USB audio and computer USB audio Listeners who want 3.5mm and 4.4mm outputs in a lightweight clip-on device Users who want PEQ without buying a higher-priced BTR model Not ideal for Very demanding full-size headphones that need higher sustained power Users requiring high-resolution USB decoding above 96kHz/24-bit or native DSD Systems requiring dedicated RCA, XLR or fixed-level line outputs Sending Bluetooth audio to wireless headphones or speakers EMiUZEK Buying Notes BTR13 is a Bluetooth receiver, not a Bluetooth transmitter. It makes wired headphones wireless from the source side but cannot send audio to Bluetooth headphones. The included cable is USB-C to USB-C. Lightning iPhones require a separately purchased compatible USB-C-to-Lightning data cable for wired USB audio. The highest quoted power is available from the 4.4mm balanced output at 32Ω. Choose BTR15 or BTR17 when more power or higher USB decoding capability is required. The back clip is built into the body and is not a removable protective case. A lanyard is included, but a protective case is not listed in the standard package. FAQ Should I buy BTR13 or BTR15? Choose BTR13 when low weight, lower cost, Bluetooth, PEQ and enough power for most IEMs or portable headphones are the priorities. BTR15 adds a dedicated XMOS USB controller, supports up to PCM 384kHz/32-bit and DSD256, and provides more balanced power at 32Ω. Both support 3.5mm and 4.4mm headphones, so BTR15 is mainly the better choice for higher USB capability and additional power—not simply because it is newer. Can BTR13 transmit Bluetooth audio to wireless headphones? No. It receives Bluetooth audio from a phone, tablet or computer and plays it through wired headphones connected to the 3.5mm or 4.4mm output. It cannot act as a Bluetooth transmitter. What is the difference between BT, PC and PHONE modes? BT mode is for wireless reception. PC mode receives USB audio and takes power from the USB connection. PHONE mode receives USB audio but normally disables USB charging so the BTR13 uses its own battery and reduces the drain on the phone. If the battery becomes critically low while powered off, forced charging can still occur. Does wired USB provide higher resolution than Bluetooth? USB supports driver-free PCM playback up to 96kHz/24-bit. It can avoid Bluetooth codec compression, but BTR13 does not support the 384kHz/32-bit and DSD256 USB capability of BTR15. The audible result still depends on the source file, playback software and headphones. Can I use BTR13 with an iPhone? Bluetooth works with iPhone through AAC. For wired USB audio, USB-C iPhones can use a compatible USB-C data cable; Lightning iPhones require a separately purchased compatible USB-C-to-Lightning data cable. The included cable is USB-C to USB-C. Will the microphone and buttons on my headphone cable work? The 3.5mm output supports compatible CTIA in-line controls and microphones. This does not apply to ordinary 4.4mm balanced headphone cables, which normally carry audio only. Compatibility can vary with the cable wiring and connected phone or application. Can BTR13 connect to two phones at the same time? Yes, it supports Bluetooth multipoint pairing with two devices. Only one device supplies audio at a time; pause the first source before starting playback on the second if switching does not occur automatically. Should I use the 3.5mm or 4.4mm output? Use 3.5mm for standard headphone cables, CTIA headsets and lower power needs. Use 4.4mm only with a headphone cable wired for balanced operation when more output power is useful. Do not convert a 4.4mm balanced output to a single-ended headphone with an unsafe adapter. Can it drive full-size planar or high-impedance headphones? It can drive some efficient full-size models, but its 220mW + 220mW balanced rating at 32Ω is intended for portable use. Very insensitive planar headphones, high-impedance models requiring substantial voltage or listeners needing large volume headroom should consider BTR15, BTR17 or a desktop amplifier. Does PEQ work with Bluetooth and USB? FIIO lists 10-band PEQ and GEQ support across Bluetooth codecs and USB Audio. Settings can be managed through supported FIIO Control functions or compatible desktop web control. The web controller requires a supported browser and desktop operating system. How long does the battery last? FIIO rates battery life at about eight hours, with charging taking up to approximately two hours. Actual runtime changes with codec, output connection, volume, headphone load, screen use and PEQ settings. Can I connect BTR13 to active speakers or a car AUX input? A 3.5mm connection can feed a compatible AUX input, but BTR13 does not have a dedicated fixed-level RCA or XLR line output. Begin with low volume and adjust carefully. Car mode can coordinate power behaviour with a compatible vehicle USB connection.
