skin. For best results, ensure that pin ends rest on outside of clothing.

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

Architect’s and Engineer’s Specifications

The microphone shall be a fixed-charge condenser. It shall have a cardioid polar pattern with a uniform 120° angle of acceptance and a frequency response of 200 Hz to 15,000 Hz. The microphone shall operate from an external 11V to 52V DC phantom power source or, alternatively, from a 1.5V AA/UM3 battery. It shall be capable of handling sound input levels up to 131 dB (phantom) or 115 dB (battery) with a dynamic range of 100 dB (phantom) or 84 dB (battery). Nominal open- circuit output voltage shall be 7.0 mV (phantom) or 5.0 mV (battery) at 1 V, 1 Pascal. Output shall be low impedance balanced (200 ohms – phantom, 250 ohms – battery).

The microphone shall have a 3 m (9.8') permanently attached miniature cable terminating in a TA3F-type output connector. The output connector shall connect to a TB3M-type jack on the included power module. The power module shall contain a recessed switch to permit choice of flat response or 80 Hz low-frequency roll-off. The output of the power module shall be a 3-pin XLRM-type connector.

The microphone shall be 23.0 mm (0.91") long and have a diameter of 5.3

mm(0.21"). Weight shall be 0.9 grams (0.03 oz). The microphone shall include a power module, a cable clip, a clothing clip base, a viper clip base, a magnet clip base and plate with lanyard, three single mic holders, two double mic holders, two windscreens, a battery and a protective carrying case. Finish shall be low-reflectance black.

The microphone shall also be available with a 1.4 m (55") permanently attached miniature cable terminated for use with Audio-Technica UniPak® body-pack transmitters and a variety of other manufacturers’ wireless systems. The wireless models’ dimensions, polar pattern and included accessories (excluding power module and battery) shall be identical

to those of the wired model. The microphone shall also be available unterminated.

The Audio-Technica AT898 is specified.

The Audio-Technica [AT898cW]; [AT898cL4]; [AT898cT4]; [AT898cT5] (wireless version) is specified.

The Audio-Technica AT898c (unterminated) is specified.
