500W Mono Channel Digital Amplifier Class D HIFI Power Amp Board 20Hz-20KHz Digital Amplifier Module

Use precautions:

1. Rated supply voltage is ±65V, ±58---±70V range, do not over 70V! positive and
​negative do not pick wrong
2. Recommended power supply ±65V
3. Recommended 4-8Ω / 10-18inch speaker
4. Carefully check before electricity, ensure the wiring is correct.

TDA7293/TDA7294 Mono Channel Amplifier Module Circuit PCB Bare Board 4XFB

Model: TDA7293/TDA7294
Power supply: double AC 15V to 36V (AC needs rectification and filtering) or DC positive and negative
18V to 50V.Recommended double 35V (Note that it is not a dual 35V transformer, it is positive and
negative 35V DC. And It is recommended to double 26V/200W toroidal transformer, after rectification
voltage is about DC double 35V).
