Product details

Designed for HiFi audiophiles, this amplifier allows you to operate a passive speaker. It offers the flexibility to effortlessly set up your home audio system. The V3 Mono can serve as a power amplifier for multi-channel AVRs, complementing the output power to drive high-performance speakers in home theater systems with ease. Fosi Audio has achieved a technological breakthrough through independent research and development by applying PFFB technology (Post-Filter Feedback) to the V3 Mono for the first time. This effectively overcomes the common load dependency issues of Class-D amplifiers, improves distortion, and optimizes the frequency response, significantly enhancing sound quality and performance. The audio component amplifiers feature the high-end TPA3255 Class-D amplifier chip, paired with renowned components such as Japanese Nichicon filter capacitors, ELNA capacitors, and German WIMA capacitors.
