💻 RAKOSO H400: Professional 4-Zone Wireless Streaming Pre-amplifier
💡 Product Overview
The RAKOSO H400 is a professional 4-zone wireless streaming pre-amplifier designed for whole-house audio integration. Unlike the HA400 which includes a power amplifier, the H400 acts as a high-fidelity source manager. Housed in a compact 1U rack-mount chassis, it features four independent Hi-Fi audio decoding units. It is the ideal engine for complex audio systems where you want to stream high-resolution music to multiple zones while utilizing your own external high-power amplifiers or active speakers.

FAQ
How does the RAKOSO H400 centralize a home audio system?
The RAKOSO H400 acts as a powerful hub for all your music needs. It combines a high-performance amplifier with advanced Wi-Fi and Bluetooth 5.0 streaming capabilities. By connecting your favorite passive speakers to the H400, you can stream music directly from the cloud, your phone, or your local network, effectively modernizing your entire audio setup while maintaining professional-grade sound output.
What makes the H400 different from standard wireless amplifiers?
The versatility of the RAKOSO H400 lies in its extensive range of physical and wireless inputs. Beyond high-res Wi-Fi streaming, it features Optical input for TV integration, USB DAC for PC connection, and Line-in/Line-out for traditional analog gear. This "all-in-one" design allows it to serve as the primary audio driver for your living room, home theater, or even high-fidelity desktop setup.
Can I expand the H400 into a whole-house audio network?
Absolutely. The H400 is fully compatible with the multi-room audio ecosystem. Through a dedicated mobile app, you can pair the H400 with other compatible streaming devices in different rooms. This allows you to sync the same playlist across your entire home for a seamless "party mode" or manage different audio zones independently with just a few taps on your smartphone.
Is the RAKOSO H400 compatible with high-resolution streaming services?
Yes, it is built for audiophiles who prioritize quality. The H400 supports a wide array of premium streaming protocols including AirPlay, Spotify Connect, Tidal Connect, and Qobuz. Because it streams via Wi-Fi, it can handle lossless audio files without the compression typically associated with standard Bluetooth, ensuring you hear every detail of your high-resolution music library.
How does the H400 handle wired connections like TVs or Turntables?
The H400 is designed to bridge the gap between digital convenience and analog tradition. Its Optical (S/PDIF) input ensures a lag-free, high-quality digital connection for your TV or gaming console. Meanwhile, the RCA Line-in allows you to connect analog sources such as a CD player or a turntable (with a phono preamp), making it a truly flexible amplifier that adapts to whatever playback device you prefer.
