What wireless systems are compatible with Crown head-worn mics?

Crown CM-311AE and CM-312AE mics will work with most wireless transmitters that have a three-wire configuration (separate ground, audio and bias pins) and have from 3V to 9V bias available. These mics will NOT work on transmitters that combine the audio and bias together (two-wire configuration).


Crown offers versions of the CM-311A and CM-312A mics that come pre-wired for AKG (systems using TA3F connectors), Audio-Technica (systems using Hirose HR10 connectors) and Shure (systems using TA4F connectors). The mics will not work with a system having a 1/4" input on the transmitter.
