User Manual

Subminiature Omnidirectional Condenser Microphones

Thank you for purchasing this product. Before using the product, read through the user manual to ensure that you will use the product correctly. Please keep this manual for future reference.

■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 aﬀecting voice quality

• 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-oﬀ. 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-oﬀ. The roll-oﬀ position reduces the pickup of low-frequency ambient noise (such as traﬃc,

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.

Avoid leaving the microphone in the open sun or in areas where temperatures exceed 43°C for extended periods. Extremely high humidity should also be avoided.

■Safety precaution

Although this product was designed to be used safely, failing to use it correctly may result in an accident. To ensure safety, observe all warnings and cautions while using the product.

■Cautions for the product

• Do not subject the product to strong impact to avoid malfunction.

• Do not disassemble, modify or attempt to repair the product.

• Do not handle the product with wet hands to avoid electric shock or injury.

• Do not store the product under direct sunlight, near heating devices or in a hot, humid or dusty place.

■Connection procedure

Connect the output terminals of AT8531 and AT8538 power module to the device that has a microphone input (balanced input) compatible with a phantom power supply. The output connector is an XLRM-type with polarity as shown in the ﬁgure below.
