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!
• Cardioid polar pattern
• 10 m (33 ft.) cable

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 (see figure below).
ORTF stereo recording
Developed by the French Broadcasting
Authority, this technique differs from the
XY technique by recording not only inten-
sity differences, but also delay differences.
The capsules are aligned at an angle of
precisely 110° and 170 mm / 6.7 in. apart
(see illustration below).
