What I want to see is a unit that is capable of handling several microphones at once. And then, also, like guitar systems that have the little transmitter, like the AKG Bug system, a small transmitter to plug into the back of a mic that would have to be capable of providing phantom power for condensors. This would make it possible to mic up a set of drums without using any cables. Each unit could handle, for example, 8 microphones, kinda like most interfaces these days. Then have a 1/4" or XLR output for each microphone channel coming out of the back of the wireless unit. Imagine....being able to mic up a drumset without any cables...man...that would be freakin awesome IMO, and to top it off it's all transmitting and recieving at 24-bit.
I understand that most wireless units that exist are capable of handling like 2 signals. I am not sure why there is such a limited amount, but I know there are plenty of frequencies to go around...
