The CMX380 is a mini hanging cardioid microphone designed to be used in choirs, instrumental groups and theatres, but itʼs technical qualities and design will also justify itʼs use in several recording / reproduction applications.

The unidirectional cardioid polar pattern reduces feedback to an absolute minimum. Due to the flat frequency characteristic, users, musicians, singers and performers will experience a clear natural reproduction of their instrument or voice, even when exposed to loud powerful sounds.

The slimline modest design will not disctract the attention from the vocal of instrumental performance, and will flawlessly blend into the background.

The new CHM 99 Condenser Hanging Microphone provides both ease of use and a high level of functionality. There is hardly any more affordable and simpler solution for recording choirs at worship centers. Suspended from the ceiling or a beam, the hanging microphone is aligned and then fixed in the correct position. Now use the spring steel clamp to adjust the correct angle, and off you go!
The CHM 99 is available in white or black.

XY stereo recording

Using two CHM 99 hanging microphones in an XY configuration (coincident pair) is a good way to make stereo recordings, particularly of choirs. However, sound source locations are defined only by intensity differences. Adjusting the angle between the microphones determines the width and depth of the stereo image.

ORTF stereo recording

Developed by the French Broadcasting Authority, this technique differs from the XY technique by recording not only intensity differences, but also delay differences. The capsules are aligned at an angle of precisely 110° and 170 mm / 6.7 in. apart.
