I was wondering with
the four xlr ch on the back.
one and 2 have mic/line/inst switch
pad switch. and mute
3 and 4 have just the pad
and mute. I want to use this with a duo
this thursday. Should i run
vocals into 1 and 2 And inst
into 3 and 4.. is there any
difference in the output of
these 4 chanels??
