Two-channel Power Amplifier Board TDA7377 

The TDA7377 is a new technology class AB car radio amplifier able to works in DUAL BRIDGE configuration. The exclusive fully complementary structure of the output stage and the internally fixed gain guarantees the highest possible power performances with an extremely reduced component count. The onboard clip detector simplifies gain compression operation.

Connecting to the power supply:

Connect to the adapter of the power supply:
Use the power supply in which the output is above DC12V 5A. Connect the output cable of the adapter to the 12V port of the power amplifier board. The positive connects to the “+” of the port while the negative connects to “-“.

Connect voltage converter:


Use the voltage converter in which the output is above AC12V3A. Connect the two output cables of the converter to the 12V port of the power amplifier board. Because the output of the converter is alternating current, it is not positive or negative.

Play music:


Plugin the power, and the blue power indicator will light up which means that the power amplifier board starts working. You can adjust the volume knob according to your own preferences.
