The main chip, the IRS2092S, is a chipset with an integrated audio driver IC featuring protected pulse width modulation (PWM) switches and IR complete digital audio MOSFETs. The chip is targeted at high performance class D audio amplifier applications such as home theater, home stereo, active speakers, musical instruments and professional audio applications.
RCA components using the original ROHM (Roma) semiconductor production, high precision, good stability. ROHM is one of the world&x27;s leading semiconductor manufacturers. Founded in 1958, ROHM is a multinational group company headquartered in Kyoto, Japan. "Quality First" is the consistent policy of Roma.

Wiring diagram: IRAUD200 set to DC power supply, especially suitable for use with switching power supply, ± ± voltage (three lines), DC single voltage inappropriate (two lines). If the AC voltage needs an external rectifier power supply board. This is a digital amplifier, do not need to adjust the quiescent current, as long as the measurement of the power amplifier board signal output DC voltage on it, the voltage is 0v, the specific look below:

[Supplementary notes and precautions]
1, the board for debugging a good finished board, we do not recommend that you modify any of the components on the board, replace the case, the board easily burn, for unauthorized changes to board components will not be in the warranty range, if any inconveniences ,beg to be excused
2, the amplifier has a perfect protection, including output overcurrent protection, short circuit protection and overvoltage protection, even if the output short circuit are not afraid of amplifier damage. Prevention in case, it is recommended to add conditional speaker friend protection.
3, the board is designed for mono independent, it is recommended that two independent power supply channel, if the two channels share a power supply there will be a ground loop, handling is not good there will be noise or unstable damage.
