Digital Silence

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Digital silence is a signal from the audio DAC, MFL, when there

 

 

 

 

 

 

is no input to the audio DAC, or when the player is in STOP/

 

 

 

 

 

 

PAUSE mode, or during disc changing track.

 

 

 

 

 

 

To check the MFL signal, use the following command and

 

 

 

 

 

 

check the voltage level at pin 41 of 7200:
