Crown CM311AE/TL

Designed for touring and live-sound applications, the Crown CM311AE/TL is a rugged head-worn microphone with unequalled performance. It sounds like the best handheld microphone - full, clear and distortion-free, even with the loudest singers.

The CM311AE/TL 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-cancelling ability rejects sound at a distance, such as instruments on stage and crowd noise. This results in the CM311AE/TL 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 CM311AE/TL is terminated for use with a Telex Transmitter.
