Warm Tips:
 
Decoding board power supply requirements: full-wave rectifier power supply, not less than 
 
2200 uf capacitor filter. Output voltage is not higher than 5 v direct current, the 
 
current 800 ma - 1 a, if the current power supply shortage: can produce repeated switch 
 
machine, pause and similar phenomena. Please do not use the charger to power a decoding 
 
board. Especially easy to damage the decoder board.
Speaker wiring : Amplifier output is BTL output , no common ground,The "+" and "-" of left 
 
and right channels couldn't be connected together which can cause damage to the power 
 
amplifier chip. Also can not put the speaker output from other amplifiers, can also damage 
 
to power amplifier chip
