Fosi Audio V3 Mono Combo
Mini monoblock amplifier: The V3 Mono is specially designed for hi-fi audiophiles and allows you to drive a single passive speaker with one amplifier, with a nominal power of up to 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 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 solves common load dependency issues in Class D amplifiers, improving distortion and enhancing frequency response, significantly boosting sound quality and performance.
Audiophile-grade components: The V3 Mono features the high-quality TPA3255 Class D amplifier chip, combined with well-known components such as Japanese Nichicon filter capacitors, ELNA capacitors, German WIMA capacitors, and Japanese Sumida inductors, among others. In addition, it features an upgraded four-layer PCB. This combination not only delivers high output power but also achieves a THD of just 0.006%, a SINAD of 101 dB, and an SNR of 123 dB, ensuring fidelity and sound quality.
Advanced cooling: Thanks to Fosi Audio’s groundbreaking full-device heat dissipation design, the TPA3255 amplifier chip is placed at the bottom and tightly integrated with the chassis, allowing heat to be effectively dissipated through the enclosure. Combined with dual side vents that enhance internal airflow, this ensures the V3 Mono can deliver stable high power over extended periods.
User-friendly design: Supports both XLR/6.35 TRS balanced and RCA single-ended inputs (with gain selection), with a simple toggle switch for selection. It also features an automatic power/signal detection mode to improve energy efficiency. You can further customize your preferred sound signature by replacing the standard NE5532 op-amps, with support for DIP8 dual discrete op-amps such as Sparkos SS3602, MUSES02, OPA2604, Burson V5i, V6, V7, and more.
