（AA-AB33182）
Picture Showcase

Description

This 4CH mid-power audio amplifier board is capable of delivering 100W output power per channel into a 4Ohm load based on Class D topology and Sure’s T-AMP technology, featuring high efficiency up to 95% and high sound quality with low distortion and low noise level. Easy installation, mid power output and high reliability make this audio amplifier board suitable for home audio, DIY audio, car audio and demanding industrial applications. A DC15V – 27V power supply is required.
4-channel Audio Amplifier Board

This audio module provides 4 output channels, each of which delivers 100W output power into a 4Ohm load, making it applicable to audio 4.0 systems.


Applicable to Various Applications


This multi-channel amplifier board is suitable for multi-speaker systems, such as Game Machines, Vibroacoustic Therapy Devices, Massage Chairs, Massage Tables, Theater Chairs, Racing Simulator, Arcade Machines.
One key advantage of this amplifier boards is their flat and smooth frequency response in the range of 20Hz to 20kHz. Moreover, they exhibit no attenuation in the low-frequency range of 30Hz to 120Hz, which is especially important for vibration transducers. This means that not only can these amplifier boards play full-range music with precision, but they are also capable of effectively driving vibration transducers to enhance the sensory experience for your customers.

High Quality Audio Performance
By means of dedicated PCB layout design and engineers’ attentive debugging, this mid-power audio amplifier board features such high audio performance that you can get pure enjoy of the music, whose SNR reaches 90dB and THD+N performs well as 0.03% @ 4Ohm, 1W, 1kHz.
High Reliability and Long Service Time

A low noise cooling fan together with an optimized robust heatsink are mounted atop the amplifier board to effectively decrease the temperature. Full protection circuit, like over temperature protection and overcurrent protection, is equipped on this board for high reliability and long service time.
Easy for Installation

Four screw holes provided make this amplifier board easy for installation and quick for integration in any cabinet. Thanks to the pre-mounted industrial terminal interfaces, all you need to do is to plug in cables for connection, without any demand of soldering, which is swift and convenient. Active indicator is provided on board for customers to have an overview of the operating status of the amplifier board.
