AT898 Audio-Technica | Audio-Technica

Subminiature Cardioid Condenser Mic.

AT898

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.”

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.

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.
