Wiring a preamplifier
 

Hello,
I've just finished a preamplifier using parts from White Noise Audio and DACT and I have a doubt regarding the wiring.
I have a channel selector with individual signal and ground conections for each chanel. I have a stepped atenuator in "double-mono" configuration for the stereo (that mean that each chanel has his own signal imput, signal output and ground). Taking everything toguether, I have an individual circuit for every channel that doesn't share the ground with the other... how should I wire the preamp, with every channel using his individual circuit or should I conect all the ground toghether in an eartring?
TIA.
