Fosi Audio V3 Mono Power Amplifier for Home Audio Speakers, Mini Monoblock Class D Amp
Experience extraordinary sound fidelity and amazing power with the Fosi Audio V3 Mono—a mini monoblock amplifier meticulously designed for HiFi enthusiasts. Delivering up to 240W at 4Ω, it easily powers a single passive speaker or supplements multi-channel AVR systems, making it ideal for a wide range of home audio setups. Leveraging pioneering PFFB (Post-Filter Feedback) technology, the V3 Mono overcomes typical Class-D load dependency issues for improved distortion, a more refined frequency response, and overall enhanced performance. At its core lies the TPA3255 Class-D chip, supported by top-tier components—Japanese Nichicon, ELNA, German WIMA, and Japanese Sumida inductors—plus quality four-layer PCB for peak efficiency. Its advanced cooling strategy places the amplifier chip at the chassis base, with dual side ventilation ensuring stable, high-power output during extended listening sessions. Compatibility is key when it comes to amplifiers, and the V3 Mono takes compatibility to the next level by offering both balanced XLR/¼" TRS and RCA connections—complete with an on-board toggle switch and auto power/signal sensing to boost energy efficiency. You can even personalize your sound signature by swapping out the stock NE5532 op-amps with DIP8 dual discrete op-amps. For a compact but full-featured amplifier that caters to every audio need—speakers, home theater, in-ear monitors, headphones—look no further than the V3 Mono

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, reducing noise 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 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. - V3 Mono Specifications: V3 mono stereo audio component mini power monoblock amplifier 2 channel amplifier single channel 2/2.1/3/4/5 channel class d amp tpa3255 for home theater speakers , desktop speakers , outdoor speakers , bookshelf speakers , tower speakers , floorstanding speakers , and passive speakers ZA3.
