I am a newbie to this forum, so please forgive me if this topic has been covered.
I have an MR76 that seems to have a problem with the main outputs. When I connect two 1/4" jack cables from the left and right outs into my Mackie 1202 and listen through the phone jack on the Mackie, no sound comes through. I do not encounter this problem when I go out of the phone jack on the MR 76 into a mono input on my Mackie. Any help would be greatly appreciated.
