Fosi Audio V3 Mono Power Amplifier for Passive Speakers, Mini Monoblock Class D Amplifier with TPA3255, 240W HiFi Home Theater AVR Receiver, RCA/XLR Balanced Inputs, 48V/10A Power Supply

Description

Brand: Fosi Audio

Characteristics:

  • Mini Monoblock Amplifier: Designed for hi-fi audiophiles, the V3 Mono allows you to drive a single passive speaker with an amplifier capable of delivering up to 240W @4Ω nominal power. 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, supplementing the output power to easily drive high-performance speakers in home theater systems.
  • Cutting-edge innovative technology: Fosi Audio has achieved a technological breakthrough through independent research and development, applying PFFB (Post-Filter Feedback) technology to the V3 Mono for the first time. This effectively overcomes the common load-dependence problems of Class D amplifiers, improves distortion, and extends the frequency response, significantly enhancing sound quality and performance.
  • Audiophile Components: The V3 Mono features a high-end TPA3255 Class-D amplifier chip, combined with exclusive components such as Japanese Nichicon filter capacitors, ELNA capacitors, German WIMA capacitors, and Japanese Sumida inductors. Featuring an improved four-layer PCB, it delivers high output power and premium audio quality with a total harmonic distortion of only 0.006%, a SINAD of 101 dB, and a SNR of 123 dB.
  • Advanced Cooling: Thanks to Fosi Audio's groundbreaking full-body heat dissipation design, the TPA3255 amplifier chip is positioned at the bottom and tightly integrated into the chassis, allowing heat to be effectively dissipated throughout the enclosure. Combined with the two side ventilation holes that improve internal airflow, this ensures the V3 Mono can deliver stable, high output even for extended periods.
  • User-friendly design: The V3 Mono offers flexible connections—balanced XLR/1/4" TRS and unbalanced RCA inputs with gain selection. A toggle switch allows for easy selection. Automatic power/signal detection mode ensures greater power efficiency. Customize your sound signature by replacing the stock NE5532 ops amplifiers with DIP8 dual discrete ops amplifiers such as Sparkos SS3602, MUSES02, OPA2604, Burson V5i, V6, V7, etc.
