Well i read the whole thing.But if the amps " volume knob" is set at its higest setting( high voltage) and my h/u it set at 60/80 i still hear music
BUT !!!
When i have the h/u's volume set at zero and the amp's " volume knob" set at its lowest setting( low voltage) i hear nothing.
Maybe because the amp isnt producing a signal, there fore, has no volume.
No signal= no volume
Turn the volume up on the h/u, and you get music out of it.
The gain is a mere regulator, it regulates how much AC voltage it produces when given a signal.
They have regulators for good reasons, so things dont blow up.
Turn the source volume up, turn the amps " regulator" down and you wont have a problem.
Shure you can turn down the source and turn up the regulator but thats doing things *** backwards.
Its just safer
And if you like to walk on the wild side, you do that....
