@Support Dasaita@Quick Yuan ? What number is "unity" gain located? As in the position where the sub out audio signal's level is neither boosted nor reduced. No way is it with the fader all the way down to 0, the sub is barely audible at that level. And what voltage is the sub out? 1.5v, 2v? Please respond.
