AHB2/Sansui Receiver Pre-out Sound without using volume pot


Hello!

I have fully restored Sansui 9090 that i'm using as a preamp. I've split the single pre-outs so that I can use two subs. Works fine and sounds awewome.

The mains amp is a benchmark ahb2.

Subs are both powered...Hsu.

I've noticed when the mains amp is off and the receiver volume dial is on zero, the subs are already amplifying the audio signal entering the receiver via a schiit audio DAC.

Any suggestions greatly appreciated

Thank you

Is the subwoofer playing musical beats and notes or is it a steady drone?  

avanti, the subs are both playing the lows from the music signal when the sansui volume control is fully on zero...the same signal that's going to the benchmark amplifier.
