TDA7294 Mono 100W Power Amplifier Board Finished Board

1. The noise of the switch is small and will not have too much impact on the speaker. It is recommended to add a horn protection circuit. The horn protection circuit can not only eliminate the impact noise of the power amplifier switch machine, also avoid the output DC burning the horn when the power amplifier is damaged.
2. The bottom noise is small. Zero floating small, do not need to do any debugging after installation, the output zero drift voltage will generally not 50mv, and is relatively stable.
3. Free debugging. As long as the connection is , is wrong, basically it is a success, no need to do any debugging, beginners also have a high success rate.
