CM-312A
Common name: Crown International CM-312A
Production Status: Discontinued / Vintage
The Crown CM-312A is a rugged, lightweight head-worn microphone designed for aerobics, live entertainment, and sports broadcasting. Because the microphone is positioned to the side of the mouth, breath pops are eliminated. The CM-312A sounds like the best handheld microphones. Designed for comfort, the headband fits behind the head and disappears in use.
Also available is the CM-312A/E, which connects to a wireless transmitter of your choice.
