Audio-Technica specifications AT898 Subminiature Cardioid Condenser Microphone

AT898 SUBMINIATURE CARDIOID CONDENSER MICROPHONE

•Maximum intelligibility and clean, accurate reproduction for lecturers, stage and television talent, and worship leaders

•Low-profile design (a mere 5 mm in diameter) is ideal for applications requiring minimum visibility

•Includes an extensive array of accessories

•Switchable low-frequency roll-off reduces sensitivity to popping in close vocal use

•Operates on battery or phantom power

The AT898 is designed to be worn as a lavalier or hidden in loose clothing. 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 all the bases. To change the holders, simply remove original holder and snap in the desired one. When using the AT898 in extremely close situations, slip the included open-pore foam windscreen over the mic to reduce wind noise or “popping.”

CAUTION! To avoid possible injury, use caution when affixing the AT898 viper clip to clothing. The pins are sharp and may puncture skin. For best results, ensure that pin ends rest on outside of clothing.

The AT898 requires 11-52V DC phantom power, or a 1.5V AA battery for operation. A battery need not be in place for phantom power operation.

*1 Pascal = 10 dynes/cm 2 = 10 microbars = 94 dB SPL

1Typical, A-weighted, using Audio Precision System One. Specifications are subject to change without notice.

Battery installation: 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 from the power module’s XLRM-type connector 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.

The microphone is RoHS compliant–free from all substances specified in the EU directive on hazardous substances.

Avoid leaving the microphone in the open sun or in areas where temperatures exceed 43° C (110° F) for extended periods. Extremely high humidity should also be avoided.
