Yes, the console was run reduced and luckily, no hum. That would drive me nuts (but might be easier to fix). I will have to look into what lines I am using (balanced or unbalanced).
I really appreciate your advise, thanks.
Yeah, look to see if your are using balanced cables or not.
Not sure of what all you got in the signal chain, but if it's more than a simple mic(or cd) >mixer>amp>speakers, unpatch everything from the simple chain I just described. Set board eq's to mid point.
Once you are back to basics consisting of mic(or cd), mixer and amp, then patch in just one additional component and listen....if you lose clarity or pick up noise then, it's either cables or that component's gain structure is out of whack. It might also be that the component has very narrow dynamic range.
Letitrip is most correct that a change in eq will disturb gain structure....After all, a boost is a boost, and a cut is a cut in signal strength, huh?....
So start with strip eqs flat(mid point or 0), increase your strip input gain to just under 0 on PFL meter, or lower if input clips, open amp gains to max, set masters to 0, then raise strip slider to decent listening level and listen.
From there, reduce strip input gain as you increase strip slider to maintain loudness and see if it sounds clearer. If it does, your input gain was too high.....
If there was no change in clarity and it sounds clear nuff, then tweek eq while you PLF that strip...watch the meter and listen to see if it loses clarity. The PFL meter should increase and decrease as you boost or cut the eq.
