you have one XLR input (for mic) OR 1 line input and 2 line inputs Mono
OR
one XLR input + 2 line inputs stereo (with BAL set to center)
e.g.
#1-vocal mic > xlr > XLR input
#2a-Guitar > 1/4inch jack > L (Mono) > [Set BAL to Center 0]
#2b-Guitar > 1/4inch jack > R
#3-Bass > 1/4inch jack > L (Mono) > [Set BAL to L]
OR
#3a-Bass > 1/4inch jack > L (Mono) > [Set BAL to center 0]
#3b-Synth > 1/4inch jack > R
what you get is
#1 - vocals
#2 - guitars left and right
#3 - Bass center OR Bass left, Synth right
set your levels gain, sound should be going in by now and your meter will flash.
and the sound will be coming out from Main Out / Phones.
what I've suggested is just basic use. for more information you should really learn how to use by reading the manual, mixers in layman terms is simply : Sound goes in. Sound gets mixed SOMEWHERE. and Sound goes out somewhere AND
do try my method : if using your head is too confusing, try thinking with your penis. everything becomes a lot more simpler. I got to where I am via this method lol :
Fornicate every "hole" on the mixer with a 1/4inch jack from guitar and your 1/4inch jack headphones.
