AKG CHM 21 CARDIOID CONDENSER HANGING MICROPHONE

CHM 21 
 
Cardioid polar pattern
10 m (33 ft.) cable
125° pickup angle
Especially suited for choir recordings
Integrated spring steel clamp for optimum alignment

The new Discreet Acoustics Compact Series 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!
XY stereo recording
Using two CHM 21 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.
