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
or best results, ensure that pin ends rest on outside of
