Features

• 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

• Cardioid polar pattern improving isolation of the desired sound source

• 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

Notes on use

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 the 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 the skin. For best results, ensure that pin ends rest on the 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.
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 the longest life. Remove the battery during long-term storage.
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.
