Hi Guys, I've just installed 2 patch bays into my studio and I'm having some issues. I have 1x Motu 24 i/o 2x Behringer Ultrapatch Pro 1x Aphex Aural Exciter Type C2 with Big Bottom The patch which is causing the trouble is 1&2 OUT from the MOTU, into the Exciter via the patch bay then back the board via the patch bay. When I turn the MIX knobs up on the exciter, I start to get phasing. The same happens when I push the mix of the Big Bottom up as well. I'm using all mono cables. Any ideas? Thanks in advance.
