[QUOTE="Gordon Brinton, post: 141860, member: 9814"] Re: Going to buy wireless IEM system All of the stereo units have two independent inputs/channels. If they have a mono switch, then the signal from only one input can be sent to both ears. I am guessing that most do have such a switch, but double check anyway. I would strongly recommend Mipro MI-808T/R or 909T/R because the base unit broadcasts two channels simultaneously and the body pack automatically switches to the strongest channel to prevent dropouts. Then pair that up with something like Shure SE535 or Westone UM Pro 30 or 50 and you've got yourself one kick-ass IEM system. All well within your budget. As far as frequencies go, in America, you can operate a small device anywhere between 470 and 698 Mhz, (except 608 - 614 is reserved for emergency use). The only problem is that your local over-the-air digital TV stations also fall within that range. While most all IEM transmitters have a variety of (TV) channels to choose from, if you happen to choose a channel that a local TV station is using, each can interfere with the other. You may get lots of static noise and dropouts. Also, if your IEM device causes interference to nearby TV viewers and generates complaints, you can be fined. Hence, wherever you take your IEM device, you need to discover what TV channels (frequencies) are in use in that area and avoid them. Some people use a website service like the link above, (which does not always give a complete list,) and some are carrying portable RF scanning devices to each show. To confuse matters even further, cell phones may soon be encroaching into that frequency range. The same rules apply to wireless mics. Also, avoid buying a transmitter from other counties because they may be set to operate outside of the legal range for US customers. Hope this helps. [/QUOTE]
