PRODUCT DESCRIPTION
The CM-311A offers Differoid performance in a comfortable headworn package. The CM-311A is designed to meet the most demanding touring sound applications, with its electret condenser capsule providing full, clear, and distortion-free sound. Gain-before-feedback and isolation are exceptional. Lightweight, rugged, and comfortable, the headband and mic boom are adjustable to any vocalist. CM-311A includes battery/phantom powered belt pack.
For Wired Applications
Designed for touring and live-sound applications, the Crown(R) CM-311A is a rugged head-worn microphone with unequaled 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(R) 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.
To get the maximum performance out of this microphone, take the time to adjust it to fit correctly. For best results, the CM-311A MUST be custom fitted to a single user's head.
