CARDIOID CONDENSER HEADWORN MICROPHONE
- Ideal for drummers, keyboard players or anyone requiring hands-free
operation.
- Comfortable, unobtrusive headband design with side-of-mouth pickup.
- Belt-mounted power module operates on battery or phantom power.
- Cardioid polar pattern improving isolation of desired sound source.
- Also available as: ATM73cW - less power module; 1.4m cable terminated
with locking 4-pin connector for A-T UniPak
™ wireless systems.
The ATM73a required 11V to 52V DC phantom power or a 1.5V AA
battery for operation. A battery need not be in place for phantom power
operation.
Battery installation: Remove the cap from the top of the power module.
Insert a fresh 1.5V AA battery (“+” end toward the cap release button),
then reassemble the power module. Alkaline batteries are recommended
for longest lift. Remove the battery during long-term storage.
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.
An integral 80Hz high-pass UniSteep® filter provides easy switching
from a at frequency response to a low-end roll-off. The roll-off position
reduces the microphone’s sensitivity to popping in close vocal use. It also
reduces the pickup of low-frequency ambient noise (such as trafc, air-
handling systems, etc.), room reverberation and mechanically coupled
vibrations.
For maximum stability and minimum visibility, the headband should be
worn around the back of the head, with each cushioned support pad
resting on the temple in front of the ear. The cable should remain clipped
to the headband, with slack at the boom connection. The headset is
designed so the microphone descends from the left support pad.
Avoid leaving the microphone in the open sun or in areas where
temperatures exceed 40°C for extended periods. Extremely high humidity
should also be avoided.
