Description
This stereo mid-power audio amplifier board is capable of delivering 150W output power per channel into a 4Ohm load based on Class D topology and TI’s TAS5613 amplifier IC. By giving full play to this high performance IC, this amplifier module features high efficiency up to 96% and high sound quality with low distortion and low noise level. Easy installation, mid power output and high reliability makes this audio amplifier board suitable for home audio, DIY audio, car audio, home theater and demanding industrial applications. A DC25V – 36V power supply is required.
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 94dB and THD+N performs well as 0.019% @ 4Ohm, 1W, 1kHz.
High Reliability and Long Service Time
A low noise, temperature-controlled fan together with an optimized robust heatsink are mounted atop the amplifier board to ensure sufficient heat dissipation. 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. Power indicator is provided on board for customers to have an overview of the power condition of the amplifier board. Shutdown function is offered for simple control of the amplifier board.
Four Stages Gain Adjustable
This audio module provides four stages gain for customers’ choice as 20dB, 26.8dB, 30.1dB and 32.5dB. 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 two switches on the board, no need of complex operations.
