/...with my sound system..../ We're doing a week long program at our church. I'm running sound as well as playing the keys. Today I walked in, turned on systems, all went normal. After a while, I tried turning the wireless rack of lavs on. Nothing. the lavs only go through the mains, no monitors (I"m using three monitor lines). Soon, I realized it wasn't just the lavs, it was EVERYTHING not going through the mains, and it was actually going through monitors. so. I began the trouble shooting. I checked my signal, and found the signal to be connected, routed, etc etc properly all the way to the main outs of the board. After this point, the cable goes under the floor, back to the sound room, (amps, processors, etc etc.) Nothing had been changed from last night til this morning. Why is no sound coming out of my mains???? PS. The outputs of the board go to an automixer, which also has channels from the Ambo, and three wireless channels (which don't go through the wireless rack). These channels work just fine. WHAT is my problem???????
