Brought in a bunch of Sennheisers for our upcoming passion play on Easter. They were mostly A band, tuned in the 540-560 region. Switched on the rack and the RF level meters were pretty much all pegged! (35Db) Tuned them down in the 518-530 region and found their happy spots. Still seeing 5 to 10Db RF noise, but no problem squelching that out. Bottom line, the source was the LED house lights. When I killed them, pretty much everything dropped to zero. (btw- there was also a bulge of noise in the 600 band on the B receivers.) There is about 3300 watts of LED lamps in the room, all white running off a dimmer as compared to DMX. Mix of brands. Biggest offenders were Philips lamps (A21, 11 to 12 watts.)
I thought I would post this simply as a heads-up that some LED or LED/Dimmer combos can play havoc with analog wireless.
