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.
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.
