Features

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.

Q
Has anyone used this microphone with an older SA-3050 1/3 octave RTA?

While this CM-20 microphone is designed for use with Audiocontrol's DM-RTA (in the handy reference link below) Jason, Audiocontrol does state that it can be used with many real-time analyzers. The CM-20 does require phantom power for operation. I checked the owner's manual on the SA-3050 and it appears that there is no phantom power feature to power this CM-20 calibration mic. I hope this helps! https://www.crutchfield.com/p_161DMRTAPR/AudioControl-DM-RTA-Pro-Kit.html

Greetings Dan, and thank you for your question. The Audio Control CM-20 can be used for a number of real time analyzers. We know it works with the Audio Control DM RTA, but we do not have a list of compatible devices. You would, be best to reach out to the fine staff at Audio Control for the best answer. Their number is 425-777-7723.
