The Fosi Audio V3 MONO is a compact, powerful, yet affordable 1-channel amplifier. Based on the TI TPA3255 amplifier chip, it is capable of delivering 240W into 4Ω. Additionally, this amp features a variety of audiophile components, such as Japanese and German Elna and Wima capacitors, respectively, or a duo of TI NE5532 OPAs with DIP8 pins, giving you the ability to swap them out if you want a certain coloration in the sound. In terms of connectors, the Fosi Ausio V3 offers balanced XLR and RCA inputs, as well as an speaker output terminal.

The V3 mono amplifier features PFFB technology, an advanced feedback design that significantly reduces distortion, improves linearity, and improves efficiency. It also solves the structural problem of Class D amplifiers by eliminating the load dependency inherent in this technology. In addition, the aluminum housing isolates the power supply from the amplifier section, preventing crosstalk.

The V3 amplifier is designed to integrate into a variety of configurations, allowing you to easily switch between RCA and XLR inputs using a front panel switch. Additionally, you can adjust the RCA input gain from 25dB to 31dB. Finally, if you want a different sound color, the DIP8 mounting of the TI NE5532 OPA allows you to replace them.
