I tried what you suggested and everything worked fine. So you are right, it must be something with the cables I am running out of that output.
I probably could have identified this myself, but I did not realize that when you were using the stereo outputs it only send Dly A out one and only Dly B out the other.
So that solves that problem! Thank you very much for your help. I was afraid I was going to have to mail it in.
One other question if you don't mind…Is there any way to power down the unit other than just unplugging it?
