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.

Current consumption

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.

 Shure MX412SE/C 12-inch (30 cm) Gooseneck Condenser Microphone, Shock Mount, Flange Mount, 10-foot (3 m) Side-Exit Cable (or Bottom-Exit), Snap-Fit Foam Windscreen, In-Line Preamp, Cardioid.

Shure Microflex MX412SE/C microphones are miniature gooseneck-mounted electret condenser microphones designed for speech and vocal pickup. Their high sensitivity and broad frequency range make them suitable for recording, as well as sound reinforcement applications.

The MX412SE/C microphone can be screwed onto a mic stand or the supplied 5/8 inch 27-threaded flange. They can be easily changed from side-exit to bottom-exit to conceal the cable. All models include an in-line preamplifier and a 3 m (10 ft) cable. Each microphone is available with interchangeable cardioid, supercardioid, or omnidirectional cartridges.
