Picture Showcase

Description
This Class D stereo mid-power audio amplifier board is able to deliver 50W output power per channel into a 6Ohm load with the adoption of TDA7492 as the driver. It features high efficiency up to 95% and high sound quality with low distortion and low noise level. Easy installation, high reliability and mid power output makes this audio amplifier board suitable for home audio, DIY audio, desktop amplifier, toy audio and demanding industrial applications. A DC10-27V power supply is required.



High Quality Audio Performance

By means of the dedicated PCB layout design and engineers’ attentive debugging, this mid-power audio amplifier board features high audio performance, whose SNR reaches 87dB and THD+N performs well as 0.026% @ 4Ohm, 1W, 1kHz.
High Reliability and Long Service Time

The idle power of this module is 1.9W and the standby power is only 0.2W. An optimal heatsink is mounted atop the amplifier board for better heat dissipation, which improves its stability. Mute and Standby functions are offered with this amplifier module for easy control. Full protection circuit, like over temperature protection, overcurrent protection and reverse polarity 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.
