Wired Description

The AT899 is a subminiature clip-on/lavalier condenser microphone with an

omnidirectional polar pattern. It is designed to provide accurate reproduction for

vocalists, lecturers, stage and television talent, and houses of worship.

The microphone is intended to be worn on the clothing or hidden in props for excellent

yet unobtrusive sound pickup. The wide-range capability of the microphone ensures

clean, accurate reproduction with high intelligibility for speakers, presenters and other

performers. Its small size makes it ideal for use in applications where minimum visibility

is required.

The microphone requires 11V to 52V phantom power or a 1.5V AA battery for

operation. A battery need not be in place for phantom power operation.

The microphone includes a permanently attached 3 m (9.8') long, 2.0 mm (0.87")

diameter, 2-conductor shielded cable. Its free end connects to the provided AT8537

power module via a TA3F-type connector. The output of the power module is a 3-pin

XLRM-type connector.

A recessed switch in the power module permits choice of ﬂat response or low-

frequency roll-o (via integral 80 Hz high-pass ﬁlter) to help control undesired

ambient noise.

The microphone comes equipped with a power module, a cable clip, a clothing clip

base, a viper clip base, magnet clip base and plate with lanyard, three single mic

holders, two double mic holders, two windscreens, two element covers and a battery.

A protective carrying case is also included. All AT899 models are available with a low-

reﬂectance black ﬁnish; selected models are available in beige.

Operation and Maintenance

The AT899 requires 11V to 52V phantom power or a 1.5V AA battery for operation. A

battery need not be in place for phantom power operation.

To install the battery, unscrew the base of the power supply unit and insert one AA

battery into the battery compartment, being certain to observe battery polarity as

marked. Then simply screw the base shut. Alkaline batteries are recommended for

longest life. Remove the battery during long-term storage.

Output is low impedance (Lo-Z) balanced. The signal appears across Pins 2 and 3;

Pin 1 is ground (shield). Output phase is “Pin 2 hot”— positive acoustic pressure

produces positive voltage at Pin 2.

An integral 80 Hz high-pass ﬁlter provides easy switching from a ﬂat frequency

response to a low-end roll-o. The roll-o position reduces the microphone’s sensitivity

to popping in close vocal use. It also reduces the pickup of low-frequency ambient

noise (such as trac, air-handling systems, etc.), room reverberation and mechanically

coupled vibrations. To engage the high-pass ﬁlter, use the end tip of a paperclip or other

small pointed instrument to slide the switch toward the “bent” line.

For use as a lavalier, attach the microphone about six inches below the chin. Anticipate

movements that may cause the microphone to rub against or be covered by clothing,

and position the microphone to avoid it.

The included single and double mic holders are interchangeable with the included

bases. To change the holders, simply remove original holder and snap in the desired

one. When using the microphone in extremely close situations, slip the included

open-pore foam windscreen over the mic to reduce wind noise or popping. Use the

included element cover to protect the microphone element from contaminants.

CAUTION! To avoid possible injury, use caution when axing the microphone viper

clip to clothing. The pins are sharp and may puncture skin. For best results, ensure

that pin ends rest on outside of clothing.

Avoid leaving the microphone in the open sun or in areas where temperatures exceed

110° F (43° C) for extended periods. Extremely high humidity should also be avoided.

Wireless Models Description

The microphone is also available in a variety of terminations for use with Audio-

Technica and many other manufacturers’ wireless systems. No power module or

battery is included (or required) with the wireless models. The wireless models’

dimensions, polar pattern and included accessories are otherwise identical to those

of the AT899.

The AT899cW is also available unterminated as the AT899c.
