■Features

•Clip-on lavalier mic provides high intelligibility for lecturers, stage/TV performers and singers

•Designed to be worn as a lavalier or hidden in loose clothing or in the hair

•Wide-range capability ensures clean, accurate reproduction

•Small size provides excellent yet unobtrusive sound pickup

•Rugged design and construction for reliable performance

•MT830a and MT830R wired version's power module (AT8531 / AT8538) include a high-pass

filter that provides a steep low-frequency attenuation to improve sound pickup without a ecting voice quality

• 1 Pascal = 10 dynes/cm2 = 10 microbars = 94 dB SPL

* Typical, A-weighted, using Audio Precision System One.

For product improvement, the product is sublect to modification without notice.

•The power module (AT8531) of MT830a can be operated on battery or phantom power

•Wireless version equipped with cW-style locking or cH-style screw-down 4-pin termination for Audio-Technica wireless systemss

■Notes on use

MT830a wired version includes a power module AT8531 that requires 11V to 52V DC phantom power, or a 1.5V AA battery for operation. A battery need not be in place for phantom power operation. An integral 80Hz high-pass filter provides easy switching from a flat frequency response to a low-end roll-o . The output of the power module is a 3-pin

XLRM-type connector.

MT830R wired version includes a power module AT8538 that requires 11V to 52V DC phantom power only. Also has an integral 80Hz high-pass filter for a low-end roll-o . The roll-o position reduces the pickup of low-frequency ambient noise (such as tra c, air-handling systems, etc.), room reverberation and mechanically coupled vibrations.

MT828cW and MT828cH wireless versions do not contain power module and includes clothing clip and windscreens only. 1.4 m cable terminated with locking 4-pin connector. The connector is also compatible with Audio-Technica cW and cH type body-pack transmitters.
