Specications are subject to change without notice.
The donut-shaped moisture guard is provided to protect the element from
sweat and moisture. Position the moisture guard as close to the element as
possible to provide maximum protection. To remove the moisture guard, rst
remove the element cover and place it out of harm’s way. Gently slide the
moisture guard over the element. Replace the element cover.
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 designed for headworn
use. It shall have an omnidirectional polar pattern and a frequency response
of 20 Hz to 20,000 Hz. The microphone shall operate from an external 11V
to 52V DC phantom power source. It shall be capable of handling sound
input levels up to 135 dB with a dynamic range of 104 dB. Nominal open-
circuit output voltage shall be 3.5 mV at 1V, 1 Pascal. Output shall be low
impedance balanced (250 ohms). The microphone shall be RoHS compliant.
The microphone shall have a 1.4 m (55") permanently attached miniature
cable terminating in a locking 4-pin output connector. The output connector
shall connect to a jack on the included power module. The output connector
shall also connect to any Audio-Technica UniPak
®
body-pack wireless
transmitter. 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 an underear headworn design with a diameter of 2.6
mm (0.10"). Microphone, boom and earpiece weight shall be 2.6 grams (0.09
oz). The microphone shall include a power module, a cable clip, a dual-ear
mount, two windscreens, two element covers, a moisture guard, a belt clip
and a carrying case. Finish shall be low-reectance black [beige].
Wireless models of the microphone shall also be available, 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 belt
clip) shall be identical to those of the wired model. The microphone shall
also be available unterminated.
