Crown CM-311A Microphone

Headworn Microphone

Designed for touring and live-sound applications, the Crown® CM-311A is a rugged head-worn microphone with unequalled performance. It sounds like the best handheld microphones—full, clear, and distortion-free, even with the loudest singers.

The CM-311A is the latest version of the Crown’s proprietary Differoid® technology. Its cardioid pickup pattern rejects sounds from the rear, such as floor monitors. Its noise-canceling ability rejects sounds at a distance, such as instruments on stage and crowd noise. This results in the CM-311A having outstanding gain-before-feedback and isolation.

Lightweight and comfortable, the mic’s headband and boom adjust to fit any singer. An included pop filter greatly reduces breath noise and pops. Because of the boom’s unique behind-the-ear design, it does not cover up the singer’s face.

Two models are available: CM-311A and CM-311AE. The CM-311A is powered by a 9V battery or phantom power. It has a battery belt pack with an on/off switch, a programmable mic on/off switch, and a "Mic On" LED. The CM-311AE is a pig-tail version allowing you to connect it to the wireless transmitter of your choice.

NOTE: Putting an XLR connector on the CM-311AE and connecting to a mic input with phantom power WILL damage the mic element. For wired applications, use the CM-311A.
