Fosi Audio MC351 2.1 Channel Integrated Amplifier

Fosi Audio MC351 2.1 Channel Integrated Amplifier

Equipped with a built-in DAC, the MC351 supports four types of digital inputs. Naturally it has a stereo amplifier with outputs for passive speakers but, unusually, it also has a built-in mono subwoofer amplifier with outputs for a passive subwoofer while also including the more usual pre-out, allowing various 2.1 system configurations. The inclusion of a circular VU meter adds a touch of vintage aesthetics, providing audio enthusiasts with visual and auditory pleasure.

This all-in-one DAC amplifier features high-resolution decoding capabilities, supporting Bluetooth, USB, Optical, and Coaxial digital inputs. With its extensive input and output options, you can easily set up a 2.1 home theatre or Hi-Fi audio system.

The MC351 has high power and great sound. Equipped with two high-end Texas Instruments TPA3255 Class-D amplifier chips and a 100-fin heatsink, the MC351 can stably output up to 165W x 2 + 350W power in a 2.1 channel setup. The dual PCBA separated design ensures that the input and output signals do not interfere with each other, providing you with the purest and most impeccable sound quality.

The user-friendly control design supports one-touch switching between 5 input modes and includes bass and treble controls, with central detents for tone defeating, for easy sound customization. It also features an automatic standby function, entering standby mode after 2 minutes of no signal input to effectively reduce power consumption.

The vintage charm of the eye candy round mini VU meter adds a classic retro vibe to your sound system. The needle of the level meter will dance to the music, providing you with both visual and auditory enjoyment. The MC351 is an excellent companion for turntables, allowing you to relive classic tracks.

The MC351 features exquisite craftsmanship. With an all-aluminium-alloy CNC integrated design and a finely sandblasted metal finish, the MC351 boasts a seamless body with no visible screws, showcasing minimalist aesthetics. The all-metal body ensures durability, and you can enjoy the peace of mind provided by Fosi Audio's 24-month warranty.

Why Choose The Fosi Audio MC351?

The Fosi Audio MC351 2.1 Channel Integrated Amplifier is the kind of all-in-one powerhouse that makes you rethink what a compact amp can actually do. With a built-in DAC handling Bluetooth, USB, Optical and Coaxial, it’s ready to anchor anything from a slick 2.1 home theatre to a no-nonsense hi-fi rig, and the inclusion of a dedicated mono subwoofer amp for a passive sub is a genuinely bold move. Under the hood, dual Texas Instruments TPA3255 Class-D chips and a chunky 100-fin heatsink push out a muscular 165W x 2 plus 350W for the sub at 4Ω, all while keeping THD down at a vanishingly low ≤0.03% and SNR north of 100dB. The dual-board layout keeps signals clean, the 4700μF capacitors add grip and slam, and the bass/treble controls (with centre detents for tone defeat) let you dial things in without fuss. Then there’s that circular VU meter — pure retro eye candy — its needle dancing along as the all-aluminium chassis sits there looking seamless and serious. It’s punchy, versatile, and just a little bit indulgent in the best way, delivering high power and surprisingly refined sound with minimal drama.
