[QUOTE="Henry Cohen, post: 50478, member: 123"] Re: Proximity between IEM transmitters and wireless receivers It's not so much a question of the proximity of the electronics as it is the antennas. It's perfectly fine to mount the mic receivers and IEM transmitters in the same rack (separated by a few rack spaces). But the antennas for the respective systems should have some physical separation. I've not done out of band emissions susceptibility testing of the Line 6, but I'd bet they're pretty deaf two octaves away. That said, if the antennas are too close, you might find the receivers vulnerable to IEM frequencies exactly 1/4 of the tuned mic frequencies if strong enough harmonics are generated in the transmitters.
