bit new to live mixing so any help here would be appreciated...i have a 2 channel 31 band EQ and all of my front of house is in mono. Can I use channel A on my EQ for my front of house and use channel B for my foldback (monitors)? Will it work? Is it stupid? Is there any reason why I have to use both channels for front of house? I'm not running anything but vocals through the PA (guitar and drums are using only on stage sound...room is not that big). any help here please!!
