Individual sound signature by replacing the standard NE5532 Ops amplifiers with DIP8 dual discreet ops amplifiers such as Sparkos SS3602, MUSES02, OPA2604, Burson V5i, V6, V7 etc.
Mini Monoblock Amplifier The V3 Mono is designed for HiFi audiophiles and allows you to power a single passive speaker with an amplifier that delivers up to 240W @4Ω rated power. It offers the flexibility to build your 2/3/4/5 channel home audio system effortlessly. The V3 Mono can serve as a power amplifier for multi-channel AVRs and complement the output power to easily operate high-performance speakers in home theater systems.
Innovative cutting-edge technology: Fosi Audio has achieved a technological breakthrough through independent research and development by applying PFFB (Post-Filter Feedback) technology to the V3 Mono for the first time. This effectively overcomes the usual problems of load dependence of Class D amplifiers, improves distortion and extends frequency response, significantly increasing sound quality and performance.
Audiophile Components The V3 Mono features a high-end Class D amplifier chip TPA3255, combined with exclusive components such as Japanese Nichicon filter capacitors, ELNA capacitors, German WIMA capacitors and Japanese Sumida inductors. With an improved four-layer PCB, it offers high output power and first-class audio quality with a distortion factor of only 0.006%, a SINAD of 101 dB and an SNR of 123 dB.
ADVANCED COOLING Thanks to Fosi Audio groundbreaking full body heat dissipation design, the TPA3255 amplifier chip is placed at the bottom and closely integrated into the case, allowing heat to be dissipated effectively through the case. Together with the two side ventilation holes that improve internal airflow, this ensures that the V3 Mono can deliver stable, high output power even over extended periods of time.
