I feel that I am getting closer to understanding sound at my level but I have come up with a list of questions that I commonly run into. I have looked these questions up and feel that while there are comments that could answer these questions...somehow they don't for me. If you care to take a crack at answering my quandries, I would appreciate it. 1) What problems might arise from running 6 wireless mics through a compressor or a reverb unit as a group? I recognize that the compression will only affect the strongest signal on stage at the time, but will it hurt quality or will the reverb unit hurt quality? I can’t afford good compression and reverb for all mics individually currently. 2) When to use TRS and when to use XLR…and what’s the point of TS to begin with other than expense? Mostly I’m curious about plugging in my Shure slx4’s but is there a major difference between balanced TRS and XLR cables? 3) In setting console gain I usual hear to add gain until the signal is around 0 or (unity) on the meter but then usually the very next thing that is said is to adjust it until it sounds correct (volume) on the fader at….0? What am I to make of that? Do I set gain to signal unity or is fader unity…and which of these is a better way of setting mix gain? 4) I have heard only of when to engage the HPF but never of when it is beneficial to disengage…when should I turn HPF on, when off? 5) What is the best way to set sweep eq…turn the eq up and then sweep until you find bad sound and then turn the eq down? Or do I have that backward? 6) Sometimes when I set the factory default gain on the body mic to “mic”(shure slx4) I get an unpleasant sound….is this a problem at the console or at the mic pack or placement? How should I set gain on the mic itself when there is no clear factory default but a slider or wheel of sometype?
