[QUOTE="ghostinthemachine, post: 62824, member: 760"] I have a QSC USA 1300 amplifier here of a friend. The B channel speaker relay is not engaging. At first I thought the channel is dead but after poking around with the oscilloscope I confirmed that its not the case. It produces signal up to the relay and I confirmed this audibly. Looking at the schematic it could be caused by a few things. Anybody got some pointers for me whilst I am poking around some more? Thanx in advance! [/QUOTE]
