- Hypercardioid polar pattern
- 38 cm long
- 95° pickup angle
- For acoustically difficult environments
- Connects easily via XLR connector
The hypercardioid polar pattern with its narrow 95° pickup angle is suited best for situations where noise typically occurs from all sides (particularly in worship centers), where people talk into the microphone from a greater distance, or where several talkers are grouped side by side. Two different lengths are available. The .exible joint ensures optimum alignment of the gooseneck to any talker position. Several options are available for installation, i.e., stand, tabletop installation, and lockable.
Choosing polar patterns
Selecting the correct polar pattern for installed sound is difficult since it depends on a variety of factors. Of course the acoustics of the room play a key role. For highly reverberant rooms such as worship centers, a hypercardioid polar pattern will be the best choice to avoid high levels of unwanted noise. Correct placement of the loudspeakers is also essential. If the speakers project right at the capsule, a hypercardioid will be your best bet. The most difficult task, however, is trying to judge how the talkers will behave. For talkers who are inexperienced or move around a lot, be sure to choose a cardioid polar pattern for reliable pickup; talkers at a greater distance from the mic will be served best by a hypercardioid.

- 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 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.
