Description

Introducing the Fosi Audio V3 Mono Mini Power Amplifier—a debut Class D amplifier engineered with cutting-edge PFFB technology to elevate sound purity and optimize system efficiency. Building on the success of the V3 stereo amplifier, the V3 Mono is meticulously crafted to deliver an unmatched audio experience for discerning listeners. With versatile input options including RCA, XLR, and ¼" TRS, the V3 Mono offers flexibility and high-fidelity sound quality with impressive SINAD levels of 101dB (RCA) and 93dB (XLR), and an exceptional SNR of ≥123dB. Boasting powerful output capabilities of 240W @ 4Ω (mono) or 100W @ 4Ω (stereo), it’s the ideal amplifier for audiophiles seeking top-tier performance. The V3 Mono also features Automatic Signal Sensing, which places the amplifier in standby mode after 10 minutes of no signal input, reducing power consumption and enhancing energy efficiency. Designed with a minimalist aesthetic, it seamlessly integrates into any environment—from home theaters and study rooms to desktop setups and studios—bringing exceptional sound to every space.

HIFI MINI MONOBLOCK AMPLIFIER FOR FLEXIBLE MULTI-CHANNEL AUDIO SYSTEMS

The V3 Mono is a mini monoblock amplifier designed for discerning audiophiles. It allows you to drive a single passive speaker with exceptional power, delivering up to 240W @ 4Ω of rated output. This flexibility makes it ideal for building 2, 3, 4, or 5-channel home audio systems with ease. But the V3 Mono's capabilities extend beyond just powering your speakers. It can also serve as a power amplifier for multi-channel AVRs, boosting their output to effortlessly drive even the most demanding high-power speakers in your home theater system. With the V3 Mono, you'll experience the full potential of your audio equipment, enjoying rich, detailed sound that brings your music and movies to life.

REVOLUTIONIZES CLASS-D AMPLIFICATION WITH PFFB TECHNOLOGY

Fosi Audio has made significant strides in audio technology by application of Post-Filter Feedback (PFFB) technology to its V3 Mono amplifier. This innovative approach addresses the inherent limitations of traditional Class-D amplifiers, particularly their sensitivity to varying load impedances. By incorporating PFFB, Fosi Audio has successfully mitigated distortion and optimized frequency response, resulting in a substantial enhancement of overall sound quality and performance. This breakthrough signifies a new era in Class-D amplification, promising a more refined and immersive audio experience.

OPTIMIZED HEAT DISSIPATION FOR RELIABLE POWER OUTPUT

The V3 Mono features Fosi Audio's advanced full-body heat dissipation design, with the TPA3255 amplifier chip positioned at the bottom for efficient heat management. The seamless integration into the chassis ensures effective heat dissipation, while dual-side ventilation holes improve airflow. This design allows for stable, high-power output even during extended use, maintaining optimal performance without overheating.

PURE AUDIO PERFORMANCE WITH AUDIOPHILE-GRADE COMPONENTS

The V3 Mono amplifier is designed for outstanding sound quality using top-tier components like the TPA3255 Class-D chip and high-grade parts from brands such as Japanese Nichicon filter capacitors, ELNA capacitors, German WIMA capacitors, and Japanese Sumida inductors, etc. Its advanced four-layer circuit board ensures better reliability and performance. With ultra-low distortion (0.006%), a high signal-to-noise ratio (123dB), and excellent clarity (101dB SINAD), it delivers crystal-clear, accurate, and detailed audio for an exceptional listening experience.

TAILOR YOUR AUDIO EXPERIENCE WITH EASILY REPLACEABLE DIP8 DUAL DISCRETE OP-AMPS

The Fosi Audio V3 allows for audio customization by replacing the stock NE5532 op-amps with higher-quality DIP8 dual discrete op-amps like Sparkos SS3602, MUSES02, OPA2604, Burson V5i, V6, V7, and more. This enables users to tailor the sound to their preferences, influencing factors like frequency response, noise floor, distortion, and soundstage. By experimenting with different op-amps, users can achieve their desired sound signature, whether it's warm and tube-like or analytical and precise.

MINIMALIST DESIGN WITH EXCEPTIONAL POWER FOR ANY SETTING

The V3 is a versatile mini power amplifier that can be used for various audio setups, including home theater, desktop, outdoor, and bookshelf systems. It features a powerful TPA3255 Class-D amplifier chip, offering high-quality audio performance and energy efficiency. With its compact design and flexible connectivity options, the V3 is a great choice for audio enthusiasts seeking a high-performance solution.
