If I recall correctly, there was a post where someone was able to reduce the output noise/hiss by adjusting the gain in the DSP via SA. For comps, you need less gain so the DSP is a good place to drop this gain, hopefully dropping the noise/hiss level as well.
Can anybody confirm this?
You see that is the interesting part, The noise will go away if I "MUTE" the amp in SA, but is otherwise unaffect by ANY parameters.
I should have a chance to play with them this weekend. I will take my laptop to a show and see what happens.
Maybe the mute opens output relays or something like that. CROWN should advise what stage gets muted by MUTE in SA.
