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 Specications
The microphone shall be a xed-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 at
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-reectance 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.
