So i've had this mixer http://bavasmusic.com.au/store/images/images_big/XEN1202FX_big.jpg for a little while, but have not used it quite yet. My question is, it only has four xlr inputs, and the rest are mono..... So which mics should be plugged in mono. overheads?? Also, does it depend on which program i use to determine if these will all show up on different tracks?
