Product Research


Overview: The AudioControl CM-20 audio measurement microphone offers an excellent frequency response and lasting durability. Designed for calibrating both car-audio and pro-audio sound systems, the CM-20 is rugged enough to be taken "on the road" and is the perfect match for AudioControl's DM-RTA signal analyzer. It features a 1/4" back electret condenser capsule, with omni-directional pickup pattern, and a male XLR socket for a balanced, high-quality connection to your test equipment (sold separately). The CM-20 requires phantom power for operation.
