Bring streaming, high-performance digital-to-analog conversion and system control together with the Fosi Audio S3. Designed as an all-in-one HiFi music streamer, DAC, digital transport and preamplifier, the S3 makes it easy to modernize an existing stereo system or build a flexible new setup around a power amplifier, active speakers and subwoofer.
At the heart of the S3 is an AKM AK4493SEQ DAC paired with an Amlogic A113X processor and OPA1612 op-amps. Its balanced audio architecture separates analog and digital circuitry and incorporates premium components including ELNA capacitors and ultra-low-noise power regulation to help deliver clean, detailed sound with low distortion. Balanced XLR and RCA outputs give you the flexibility to connect to a wide range of power amplifiers and powered speakers.
Enjoy convenient wireless music playback with dual-band Wi-Fi 6 and Bluetooth 5.3. The S3 supports popular streaming technologies including Apple AirPlay 2, Google Cast, Spotify Connect, TIDAL Connect and DLNA, allowing you to stream from compatible music services, mobile devices and network storage. Wired Ethernet is also available for a stable network connection.
The S3 is equally at home as the centre of a music and TV system. HDMI eARC lets you connect a compatible television directly to the S3, while the dedicated subwoofer output makes it easy to expand your stereo setup into a 2.1-channel system. Optical and analog RCA inputs accommodate additional audio sources, while optical digital output lets the S3 function as a network transport with an external DAC or compatible audio component.
Control playback and settings using the included Bluetooth remote or the Fosi Audio app for compatible iOS and Android devices. App-based sound adjustment includes a 10-band EQ, giving you additional control over the sound to suit your system, room and listening preferences. A 12V trigger output can also synchronize power with compatible audio equipment for more convenient system operation.
With extensive wired and wireless connectivity packed into a compact 17.3 cm-wide chassis, the Fosi Audio S3 provides a versatile digital hub for music streaming, TV audio and high-performance stereo systems.
