DescriptionFosi Audio P4 is a compact solid-state stereo preamplifier that brings three RCA sources under one volume and tone-control stage.Its motorized analog volume control, remote operation, three-level gain, tone bypass and separate pre-out make it a practical partner for power amplifiers and powered subwoofers.Why it stands outThree-source analog hubThree RCA inputs allow convenient switching among a DAC, streamer, CD player or other line-level source.Motorized analog volume controlThe remote-driven analog potentiometer provides smooth level adjustment without replacing the analog signal path with digital volume control.Flexible tone and gain adjustmentBass, treble, bypass and three gain levels help match different source levels and listening preferences.Low-noise preamplifier performanceHigh SNR and low THD+N support clean system control in a compact all-metal chassis.Best for Systems with multiple line-level analog sources Power amplifiers needing source selection and remote volume Powered speaker systems 2.1 systems using the volume-controlled pre-out Not ideal for Driving passive speakers directly Turntables without a built-in or external phono preamp Users needing Bluetooth or digital audio inputs EMiUZEK Buying Notes P4 is a preamplifier and cannot directly power passive speakers. All three inputs are line-level RCA; a standard turntable requires a phono preamp. Pre-out is volume controlled and suitable for compatible powered subwoofers or powered speakers. Frequently asked questionsCan P4 drive passive speakers?No. Connect its RCA output to a power amplifier that drives the passive speakers.Does P4 include Bluetooth?No. It is an analog RCA preamplifier.Can I connect a turntable?Only if the turntable has a built-in phono stage or you use an external phono preamp.What is pre-out for?It provides a volume-controlled line-level output for compatible powered speakers, a powered subwoofer or downstream equipment.Can tone controls be bypassed?Yes. The bypass function provides a more direct signal path when tone adjustment is not needed.What does the gain setting do?The three gain levels help match differing source output levels and system sensitivity.HOW TO CONNECTPower amplifier systemSource: DAC, streamer, CD player or phono preampConnection: RCA inputOutput: RCA outputTarget: Power amplifier → passive speakersNote: Select the source and use P4 for volume control.Powered speaker systemSource: Up to three line-level sourcesConnection: RCA inputOutput: Pre-out or RCA outputTarget: Powered speakersNote: Begin with conservative volume settings on both devices.2.1 systemSource: Line-level sourceConnection: RCA inputOutput: RCA output + pre-outTarget: Power amplifier and powered subwooferNote: Use pre-out for the powered subwoofer and confirm crossover settings.Technical SpecificationsAudio performance Feature Specification Product type 2.0-channel solid-state preamplifier SNR ≥110dB Dynamic range ≥110dB THD+N ≤0.003% Crosstalk ≥105dB Noise floor ≤9μV Frequency response 20Hz–20kHz (±0.1dB) Tone adjustment ±12dB Connectivity and power Feature Specification Inputs RCA × 3 Outputs RCA, pre-out Gain adjustment +3dB / +6dB / +9dB Volume control Motorized analog potentiometer with remote Power supply DC 12V / 1.5A Recommended System Setup Setup Connection Stereo separates Sources → P4 → Power amplifier → Passive speakers Powered speakers Sources → P4 → Powered speakers 2.1 separates Sources → P4 → Power amplifier + powered subwoofer Additional Product ContentFosi Audio product comparisonCompare the main Fosi Audio preamplifier choices by source support, outputs and the features that most affect system design.
