We recommend connecting the signal cables when the D/A Converter and all other units of the audio 
system are switched off.  
 
The D/A Converter has two types of analog audio outputs: unbalanced audio signal (RCA/phono) and 
true balanced audio signal (XLR –pin 2 is positive phase, pin 3 is negative phase and pin 1 is chassis 
ground). 
 
We recommend using the balanced XLR outputs from the D/A Converter, as this will give the highest 
level of sound quality.
