Dual Control: XPR4550

[trumpetman12]

Hey folks, I'm working on trouble shooting a small problem for some Connect Plus users.

They have a two-station dispatch setup in a small closet sized room. Each station has an XPR4550 sitting on a shelf in front of them (behind their computer monitor) and an RMN5050 desktop mic that they use. They're just far enough away from each other to need 2 microphones, but still close enough to cause some awful feedback when one radio keys up. They are operating on a single channel 99.9% of the time. The AGC has been turned way down, but still they're finding it next to impossible to set the volume and leave it without some field units being way too quiet or way too loud.

Are there any solutions that you folks can suggest as far as maybe running a single base station with 2 separate microphones, or a dual control head setup, or any other idea that might make them happy? Trying to avoid hacking up any cables, but if there's an easy fix to combine two mics into one port, that would be ideal.

Thanks!

Have you adjusted the desk mic sensitivity via the pot on the back of the mic??

Very easy to set up...just get a standard 'Maxtrac' style microphone with the RJ45 connector. Wire an RJ45 box with the desired length of CAT5 (or whatever) cable into the rear accessory connector of the radio...you'll only need three wires...ground, PTT and TX audio. The XPR will allow you to set separate input levels for both the front and rear mics, so balancing the mics to sound the same should be a snap.
