Preparing to use my DL32 this weekend. Mapped out all my channels, based on settings for this particular band that I've mixed before on my DL1608. Went to play some music through the mains just to make sure all is working and got..nothing. The Channel I'm playing music through has visible signal. The main meter has visible signal, but nothing. When I turn up the corresponding channels in AUX 13 and AUX 14, (which also double as the main outputs, I guess) and turn up Aux 13 and Aux 14, I get sound. Why is this happening? What am I missing? I have no problem linking 13 and 14 and just mixing that way-is it something in the settings that I"m missing? regards, David
