Introducing the Fosi Audio V3 Mono Mini Power Amplifier, engineered for discerning audiophiles seeking exceptional performance in a compact form factor. This Class D monoblock delivers up to 240W @4Ω, enabling flexible multi-channel system configurations from 2 to 5 channels. The breakthrough PFFB (Post-Filter Feedback) technology addresses traditional Class D limitations, reducing distortion and expanding frequency response for superior sound clarity. Built with premium components—including the TPA3255 amp chip, Japanese Nichicon and ELNA capacitors, German WIMA capacitors, and a four-layer PCB—the V3 achieves exceptional specifications: 0.006% THD, 101dB SINAD, and 123dB SNR. Advanced full-body heat dissipation with dual ventilation ensures stable operation during extended listening sessions. Flexible connectivity includes balanced XLR/¼" TRS and RCA inputs with gain selection, plus auto power-sensing efficiency. Customize your sonic signature by swapping the stock NE5532 op-amps with premium alternatives like Sparkos SS3602 or Burson V5/V6/V7 for personalized audio refinement.
