Advantage of the Digital Amplifying:
1. Up to 90% efficiency, high power; low consumption; strong resistivity for AM;
2. Comprehensive protection: short-circuit/over-heat/over-pressure and direct current;
3. High Resolution and low distortion; provide defined trebles and deep bass;
4. No need to considerate about the problem of internal resistance when matching with the speakers;
5. Instead of analog amplifier, digital amplifier can avoid transient intermodulation distortion efficiently

Wiring instructon:
1. Make sure the correct wiring before connecting the amplifier board;
2. Speaker wiring: connects speaker "+" to Lout "-", connects speaker "-" to Rout "-";
3. Connect the audio input wire;
4. Power on the amplifier board after confirming the wiring. Remember to unplug the power if you want to change the wiring or move the board.

Note:
1. Power supply cannot be connected to the output interface of the speaker, otherwise the chip will be damaged;
2. Please mount install this amplifier board on somewhere without metal and other conductive objects to avoid causing short circuit or current sound;
