The Crown CM-311AE headset microphone is designed to meet the most demanding touring sound applications. The CM-311AE microphone has an electret condenser capsule to deliver full, clear, and distortion-free sound.
This is a cardioid pattern pickup, for use in situations where directivity is important, but gain before return is less critical. The mic is not finished, so you can use it with the wireless mic transmitter of your choice.
