Suppose you had a head with 4 stereo outs, 2 left and 2 right. Most of the time you just ran 2 extension cabs, 1 left and 1 right. Occasionally you would like to run an additional cab, say a 1x15, in mono...almost as a center channel type speaker. Is it possible to somehow use the extra two stereo outs to feed one cab a mono signal?
