[QUOTE="Nitin Sidhu, post: 10533, member: 2521"] Hello! I was wondering, there has been gig that I have had the opportunity to engineer a few times, elaborate, and we have used in excess of 50 channels of RF (iem + HH) Im no wireless expert and dont take the responsibility. But it hasn't really been working. Everyones been relying on WB6 or WSM to get the needful done. But the IEM's have a constant issue, so much so that the artists now consider it a given with iems. I know that we can face similar issues even if using 2 iem packs instead of 20. I also know that with proper coordination we can get many channels of iems to work. Antenna placement and the drill aside, 3 questions. 1. Im not too sure if the likes of WB or WSM can actually do frequency 'coordination', when multiple units can come in proximity and cause inter modulation etc ? 2. And then, why is it always the IEM's that give issue ? A higher number of HH's all seem to work clean most of the time ? 3. Thirdly, there seems to be a solid foundation with FCC in the US where TV channel frequencies etc are easily available in the public domain.... but in India, and for example, Malaysia or Singapore, how would one work with something like the Professional Wireless software etc ?
