About this item
- 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 @4¦¸ 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/?" 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. For example, it will work with Sparkos SS3602, MUSES02, OPA2604, Burson V5i, V6, V7, and more. Note: Please ensure that the device is powered off when connecting the speaker cable
