Note: Please read the product introduction.You must have some knowledge of electronics, before use must first be familiar with the board's connection, Double check connection, do not over voltage, overload, short circuit, etc. may burn out key parts.

Wiring method suggestion:
Connect speaker first, audio input line, then Power input, confirm the correct wiring and all connection must be fixed securely (loose cable connection likely to cause a short circuit), finally turn on the board. Do not make any cable connection / changes after power on, Switch off power if you need to do so.
The speaker output "+" "-" line is independent, not sharing common (-)

Do not connect Power to Speaker Output terminal, it will damage the amplifier board.
