I have a Trace Elliot series 6 amp and have tried to hook up my Behringer Modulizer Pro in the effects loop for chorus etc. Every other effect I use is fine but the Behringer has a "buzz" as soon as I hook it up. I've tried taking it out of the rack and plugging it in elsewhere to eliminate the ground as a cause. I now think that it is because the Behringer has a 1/4" balanced (tip/ring/sleeve, as well as an XLR in/out). How do I hook up a balanced to an unbalanced unit easiest? I suppose I could run a 1/4 unbalanced cord from the effects send on the Trace to a direct box and then to the unit via XLR and back. This seems expensive and cumbersome. Is there a better way?
