User Manual
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
• 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 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 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.
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.
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.
