SMALL MONO-BLOCK AMPLIFIER: Designed for HiFi audiophile enthusiasts, the V3 Mono can drive one passive speaker with a single amplifier and reach a rated power of 240W@4Ω. Provides flexibility to easily build your home audio 2/3/4/5 channel system. The V3 Mono serves as a multi-channel AVR power amplifier, supplementing the output power to easily drive the high-output speakers of your home theater system
Package Contents: 1 x 48V/10A power adapter, power filter, splitter cable, Japanese instruction manual (English language not guaranteed)
Nice Heat Dissipation Design: Fosi Audio's first full-body heat dissipation design, TPA3255 amp chip is located on the bottom, tightly integrated with the chassis, effectively dissipate heat through the housing. Combined with vents on both sides to enhance internal air flow, the V3 Mono provides consistent high output for long periods of time
Innovative, cutting-edge technology: Through unique research and development, Fosi Audio achieved a technical breakthrough by applying PFFB (Post Filter Feedback) technology to the V3 Mono for the first time. This effectively overcome the common load dependency problems of class D amplifiers, improved distortion, enhanced frequency response, greatly improved sound quality and performance
HIGH QUALITY COMPONENTS: The V3 Mono incorporates high-end TPA3255 class D amplifier chip, combined with famous components such as Japanese Nichicon filter capacitors, ELNA capacitors, German WIMA capacitors, and Japanese Sumida inductors. Moreover, it has an upgraded 4-layer PCB. This combination not only ensures high output, but also reduces THD to 0.006%, SINAD to 101dB, SNR to 123dB, ensuring audio fidelity and quality
Friendly Design: Supports both XLR/¼" TRS balance and RCA single end (with gain selection) input and features an easy toggle switch for selection. In addition, it has automatic power/signal detection mode, which increases energy efficiency. You can also customize your favorite sound signature by replacing the standard NE5532 operational amplifiers to support DIP8 dual discreet operations such as Sparkos SS3602, MUSES02, OPA2604, Burson V5i, V6, V7
For better heat dissipation, we recommend using Fosi Audio cooling fan (sold separately) with an amplifier
