Description

This 4CH mid-power audio amplifier board is capable of delivering 100W output power per channel into a 6Ohm load based on Class D topology and TDA7498 amplifier IC, featuring high efficiency up to 92% 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 DC14V – 36V 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 6Ohm load, making it applicable to audio 4.0 systems.

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 95.38dB and THD+N performs well as 0.0409% @ 6Ohm, 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.

Four Stages Gain Adjustable

This audio module provides four stages gain for customers’ choice as 25.6dB, 31.6dB, 35.6dB and 37.6dB. You can select the most suitable stage for your application. The switch among the four stages gain is achieved by the different combination of the switches on the board, no need of complex operations.
