The last few weeks we have been getting very intermittent crackling on our show-run channel of com. When it really gets going, it seems to garble the sound of the calling SM. Lately it seems to be getting worse and more bothersome to the crew on headset during the show. But when I try to troubleshoot it, of course I can't get it to happen.
We have an SB-704 for the SM. On the channel in question we have ~10 RS-603 beltpacks, various headset types (mostly PH-88's and Sennheiser HMD25/26's), and a BTR-800 running 3 TR-800 wireless packs. This channel is also fed into 2 KB-702 wall speakers.
I haven't been able to tie it to any specific station/pack or interference. It really does seem to be random, although I mostly have to rely on feedback from the SM's as to when it happens. I thought it could be the wireless, but I still heard crackling when all of the packs were turned off (though BTR base station remained on). I don't know where to go from here, short of ripping apart the whole system and putting it back together, which with so few dark days, isn't a possibility.
I oversee the sound department in a smallish theater and com is my achilles heel, as I come from more of a music studio background....It is driving me mad! Please help!
Thank you in advance.
