Variant: V3 Mono Pair + 48V 10A PSU + Power Filter

Drawing inspiration from the acclaimed V3 stereo platform, the V3 Mono represents our commitment to audiophile refinement. This Class D monoblock amplifier integrates proprietary PFFB technology, engineered to elevate sonic clarity while optimizing power delivery across your audio ecosystem. Each channel operates independently, delivering dedicated amplification that transforms your listening experience with precision and finesse. A sophisticated solution for discerning listeners seeking to elevate their home audio setup.

The Fosi Audio V3 MONO is a monoblock high-power amplifier integrated with the Texas Instruments TPA3255 amplifier chip, suitable for speakers of 2Ω to 8Ω impedance. It implements Post-Filter Feedback (PFFB) technology, addressing the long-standing issue of load-dependency in Class-D amplifiers. This significantly improves distortion, linearity, and frequency response, enhancing sound purity and system efficiency. The V3 MONO incorporates balanced (XLR/¼" TRS) and unbalanced (RCA) input modes, with the latter offering 25dB/31dB gain selection to meet diverse listening preferences. It also features an automatic standby function that activates after 10 minutes of no signal input, automatically waking upon signal reception, enhancing energy efficiency and convenience.

Features 
  • Mini Monoblock Amplifier Crafted for HiFi audiophiles, the V3 Mono allows you to drive a single passive speaker with one amp, delivering up to 240W @4Ω of rated power. It offers the flexibility to build your home audio 2/3/4/5-channel system effortlessly. The V3 Mono can serve as a power amplifier for multi-channel AVRs, complementing the output power to easily drive high-power speakers in home theater systems.

  • Innovative Cutting-Edge 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 overcomes the common load dependency issues of Class-D amplifiers, improving distortion and enhancing frequency response, thereby significantly enhancing sound quality and performance.

  • Audiophile-Grade Components The V3 Mono incorporates the high-end TPA3255 Class-D amp chip, paired with well-known components such as Japanese Nichicon filter capacitors, ELNA capacitors, German WIMA capacitors, and Japanese Sumida inductors, etc. Additionally, it features an upgraded four-layer PCB. This combination not only ensures high power output but also achieves a THD as low as 0.006%, a SINAD of 101dB, and an SNR of 123dB. As a result, the fidelity and quality of the audio are assured.

  • Advanced Cooling Utilizing Fosi Audio's pioneering full-body 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 casing. Coupled with dual side ventilation holes that enhance internal airflow, this ensures the V3 Mono can deliver stable, high-power output over extended periods.

  • User-Friendly Design Supports both XLR/¼" TRS balanced and RCA single-ended(with gain selection) inputs, with an easy toggle switch for selection. Additionally, it features an auto power/signal sensing mode to enhance energy efficiency. You can also customize your preferred sound signature by replacing the stock NE5532 op-amps, supporting DIP8 dual discrete op-amps such as Sparkos SS3602, MUSES02, OPA2604, Burson V5i, V6, V7, and more.
