The level controls on the receiver/processor and sub are variable resistors which adjust the amount of voltage being let out/let in to be subjected to the fixed gain of the amplifier.


I didn't think about the XLR being 6db lower. However, the overall output signal at a given input "should" be the same, on the V1 amp it seemed like the XLR input had no "gain" adjust.

I will tinker with it here in a few minutes.
