Microphones Looking to buy 3 more wireless mic sets, need advice.

[MrPham]

We currently have 3 Audio Technica ATW-R3100BL systems. We are looking to purchase 3 more sets and have bene looking at Audio Technica ATW-3100BC. My question is should I get 3 more sets that use the same frequency's as the ones we currenty have? The range is 482-507MHZ. The new system we want to buy uses range from 541.500-560.375. Or should we go with systems that use 656.125 - 678.500? Thanks

Stick with the 500 Mhz mics. 600 Mhz will be unavailable within a few years:

It depends upon two things: What channels TV stations are using in your area, and how many systems can operate in a block of channels. 482-507 are TV channels 16-19. (You also have to differentiate between virtual channels and real channels. For example, "KOMO channel 4" in Seattle actually broadcasts on 38.) I suggest that rather than buying from a box house, consult a reputable dealer who can do proper frequency coordination for you. It might cost a bit more, but the equipment will function properly when all is done.
