Hi im new here so I dunno if im in the right section.
I just wanna now what like this things are. I can understand what they do and what the function is but I wanna know more deeper like exactly what they do and and all that so I appreciate ALL help I can get.
The things I wanna know is: Trebble, Gain, the high - mid - low, thingie on the bass mics. Thats all for now and if I can come up with anything else Ill post it.

Treble = High frequencies, think Guitar and up.

Gain/Trim = How much volume you want preamped/cut before the othe rvolume control

High-mid-low thingy? Boost/Cut? If so then its just volume for those.
