audio running through mixer when power down

Does the mixer have gain potenciometer?
How affect it to the signal when you put it to the min and the max?? some difference?

yes you can have passive filters, they usually dont touch the phase, so there is more quality instead of active filters. But if your eq amplify the signa then they are active filters...
The gain potenciometer is also an operational amplifier

What I remember is that when there is no Vcc, there is no Signal in the Out.
But for sure this kind of things happen. If you have the schematics, we can see why it does it.

tell us if the gain pot affects...
 
the audio is much worse, also the eq doesn't work, just the faders work

just checking i haven't got a didgy mixer that could electricute me!
