Sorry if this issue has been discussed many times before. I've searched a bunch and cannot fix my problem.
I've got a brand new HX Effects and Orange Rocker 15 Terror with PCP112 Cab. Everything works great as a pedal board. If I connect everything through the effects loop only or the 4CM, I get no sound at all. Silence from both channels. Updated firmware. Quadruple checked the cables. Thanks in advance for the help.
