Compact Monoblock Amplifier: Designed for HiFi audiophiles, the V3 Mono can drive a single passive speaker with a single amplifier, reaching a rated power of 240W @ 4Ω. It offers the flexibility to easily build 2/3/4/5 channel home audio systems. The V3 Mono can also function as a power amplifier for multi-channel AVRs, complementing their output power to easily drive high-power speakers in home theater systems.
Innovative, cutting-edge technology: Fosi Audio has achieved a technological breakthrough by applying PFFB (Post-Filter Feedback) technology to the V3 Mono for the first time through its own research and development. This effectively overcomes the common load-dependency problems of Class D amplifiers, improving distortion, enhancing frequency response, and significantly improving sound quality and performance.
High-Quality Components: The V3 Mono incorporates a high-end TPA3255 Class D amplifier chip, combined with renowned components such as Japanese Nichicon filter capacitors, ELNA capacitors, German WIMA capacitors, and Japanese Sumida inductors. Furthermore, it features an upgraded 4-layer PCB. This combination not only guarantees high output power, but also reduces THD to 0.006%, achieving a SINAD of 101dB and an SNR of 123dB, ensuring audio fidelity and quality.
Excellent heat dissipation design: Fosi Audio's first full-body heat dissipation design, the TPA3255 amplifier chip is located at the bottom and tightly integrated with the chassis, effectively dissipating heat through the enclosure. Combined with ventilation holes on both sides that enhance internal airflow, the V3 Mono can achieve stable high output over long periods.
User-friendly design: Supports both XLR/¼" TRS balanced and RCA single-ended (with gain selection) inputs, with a simple toggle switch for selection. Furthermore, it features an automatic power/signal detection mode for increased energy efficiency. You can also customize your preferred sound signature by replacing the standard NE5532 op-amp with support for DIP8 dual discrete op-amps such as Sparkos SS3602, MUSES02, OPA2604, Burson V5i, V6, and V7.
[※] For better heat dissipation, we recommend using a Fosi Audio cooling fan (sold separately) with the amplifier.
