@Corey > I'm a little confused which knobs you have set, a little more info would be helpful.
What do you have set to 0? There is no 0 label on the channel trims.
Which gain do you have at half? 12'O'Clock correct?
What are you comparing this to when you said "it makes signifacntly less noise in the maser then the other channels"?
Is it only 1 channel that has a lower volume than the rest?
