Audio Technica ES933H Hypercardioid condenser hanging microphone

With durable construction and unobtrusive appearance, the ES933H offers versatile solutions for speech, theater, orchestra and choir sound reinforcement and recording. The microphone's low-profile element provides a uniform hypercardioid polar pattern with 100º acceptance angle. Available in two colors: black (ES933H); white (ES933WH), the microphone offers unsurpassed immunity from radio frequency interference thanks to UniGuard® innovations. The ES933H also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.

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.
