FAQ                                                                                                     

1,open the power supply decoding board shows that”HI”

 

    Connect the power cord will connect the audio line at the same time,did not answer the audio line will show”HI”in decoding board

 

2,use some customers connected to their audio power amplifier will have noise

 

    One:using the multimeter,check whether the ground of the power amplifier on a board under the connected(audio ground wire and ground wire of power supply),then com pare the decoding ground wire is connected on the board(audio ground wire and power supply ground wire)must be broken,if the ground wire of power amplifier board is broken,so the decoding board(audio ground wire and power supply ground wire)must be connected.

 

    Two:the connection between offensive and defensive board and decoding board line if it is too long can also cause murmur voice,use a shorter wire connecting the two board is ok.
