CM-311A
Common name: cm311a
The CM-311A offers Differoid® performance in a comfortable headworn package. Designed for live sound applications, it provides distortion-free sound with exceptional isolation and gain before feedback. Its noise-cancelling ability rejects sounds at a distance. Lightweight, rugged and comfortable, the headband and mic boom are adjustable to any vocalist. Includes battery/phantom-powered beltpack with programmable mute switch for hardwired use and XLR-3M output.
The CM-311AE offers a pigtail output for use with most professional wireless beltpack transmitters.
The ASH version fits on Sony MDR7506 or MDR-V6 headphones.
