Fosi Audio V3 Mono+48V/5A
Mini monoblock amplifier: The V3 Mono is specially designed for hi-fi audiophiles and allows you to drive a single passive speaker with a single amplifier, delivering a maximum rated power of 240 W at 4 Ω. It offers the flexibility to effortlessly build your 2/3/4/5-channel home audio system. The V3 Mono can serve as a power amplifier for multi-channel AVRs and supplements the output power to easily drive powerful speakers in home theater systems.
Innovative advanced 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 resolves the common issues with load dependency in Class D amplifiers, thereby reducing distortion and enhancing the frequency response, which significantly improves sound quality and performance.
Audio-grade components: The V3 Mono features the high-quality TPA3255 Class D amplifier chip, combined with renowned components such as Japanese Nichicon filter capacitors, ELNA capacitors, German WIMA capacitors, and Japanese Sumida inductors, etc. Additionally, it features an improved four-layer printed circuit board. This combination not only delivers high output power but also achieves a THD of just 0.006%, a SINAD of 101dB, and an SNR of 123dB. This ensures the fidelity and quality of the sound.
Advanced cooling: Thanks to Fosi Audio’s groundbreaking design for heat dissipation across the entire unit, the TPA3255 amplifier chip is positioned at the bottom and tightly integrated with the chassis, allowing heat to be effectively dissipated through the enclosure. Combined with dual side vents that improve internal airflow, this ensures the V3 Mono can deliver stable, high power for extended periods.
User-friendly design: supports both XLR/6.35 TRS balanced and RCA single-ended (with gain selection) inputs, with a simple toggle switch for selection. Additionally, it features an automatic power/signal detection mode to improve energy efficiency. You can also customize your preferred sound signature by replacing the stock NE5532 op-amps, which support DIP8 dual discrete op-amps such as Sparkos SS3602, MUSES02, OPA2604, Burson V5i, V6, V7, and more.
