Fosi MC351 Class D Amplifier 2.1 Channel Bluetooth 5.3 2xTPA3255 2x165W+350W @ 4 ohm
The Fosi Audio MC351 integrated amplifier is a small all-in-one amplifier featuring two TI TPA3255 amplifier chips, enabling it to deliver up to 2x165W+350W of power at 4 ohms. This makes it possible to set up a 2.1-channel system for an immersive listening or TV experience with deep bass. A built-in DAC gives it the benefit of digital and optical inputs such as a USB-C input (24bit/96kHz), a Toslink optical input and a coaxial SPDIF input (24bit 192kHz). Digital inputs are complemented by Bluetooth 5.3 functionality supporting standard SBC and AAC codecs, as well as an analog RCA stereo input. The front panel features three potentiometers for volume, bass and treble control, as well as a small round Vumeter for an aesthetically pleasing vintage effect. A button also makes it easy to select the desired input source. A 32V/5A power supply completes the package.
The 32V/5A power supply supplied cannot match the MC351's power claims. A 48V/5A power supply (sold separately) is required.
Fosi MC351: a considerable power reserve
The MC351's two TI TPA3255 amplifier chips enable it to develop an output power of up to 2x165W at 4 ohms on its speaker terminals, and 350W at 4 ohms on its subwoofer output. One of the MC351's major advantages lies in its ability to offer this level of power and a subwoofer output on terminals. All this while maintaining a THD ≤ 0.03% and an SNR ≥ 100dB.
Fosi MC351: integrated DAC
The integration of a DAC chip in the MC351 allows it to benefit from several digital and optical inputs in addition to its analog RCA input. This DAC chip supports sampling rates up to PCM 24bit 96kHz on its USB input and 24bit 192kHz on its Toslink optical input and coaxial SPDIF input.
Fosi MC351: Bluetooth 5.3
The MC351 benefits from Bluetooth reception, and supports standard SBC and AAC codecs. A valuable feature for quick and easy use with a smartphone or tablet, for example. The Bluetooth 5.3 standard guarantees low-latency wireless transmission.
Fosi MC351: a clean power supply
Two 4700μF capacitors guarantee a stable power supply to the MC531's circuits. This not only improves the final sound reproduction, but also enhances the MC351's durability.
