The Fosi Audio MC351 is a versatile 2.1-channel integrated amplifier with a built-in DAC, combining stereo speaker and subwoofer amplification in a single compact unit. Bluetooth 5.3, RCA, USB, optical and coaxial inputs provide flexible connectivity for both modern and traditional audio sources.
Two Texas Instruments TPA3255 Class-D amplifier chips handle amplification, with the MC351 capable of delivering up to 165 W × 2 + 350 W into 4 ohms with 32 V or 48 V power supply options.
Front-panel bass and treble controls make sound adjustment quick and straightforward, while direct switching provides easy access to all five input modes. The responsive VU meter adds a distinctive visual touch, while speaker, subwoofer and 3.5 mm pre-out connections provide flexibility when building a 2.1 audio system.
