Audio Technica ES943, ES943/C Operating And Maintenance
[
Description
]
The microphone features a 55" (1.4 m)
permanently-attached miniature cable,
connected to an AT8536 power module
via internal solderless screw terminals. It
can be powered from any external 11V to 52V
DC phantom power supply. A recessed switch
in the power module permits choice of flat
response or low-frequency roll-off to help
control undesired ambient noise.
The microphone is enclosed in a rugged
housing with a low-reflectance black finish.
Two foam windscreens and an AT8460 clothing
clip are included, as well as a snap-on belt clip
for the power module.
The ES943/C is a wide-range condenser
clip-on/lavalier microphone with a cardioid
polar pattern. It is designed for quality sound
reinforcement, professional recording,
television and other demanding sound pickup
applications.
The ES943/C is intended to be worn on the
clothing for excellent yet unobtrusive sound
pickup.The wide-range capability of the microphone ensures clean, accurate reproduction
with high intelligibility for speakers,singers and
other performers.The cardioid pickup pattern
helps reject undesired off-axis sounds.Its small
size makes it ideal for use in applications
where minimum visibility is required.
Engineered Sound
while the ground (shield) connection is Pin 1.
Output is phased so that positive acoustic
pressure produces positive voltage at Pin 2, in
accordance with industry convention.
While a modern condenser microphone is
not unduly sensitive to the environment,
temperature extremes can be harmful. Avoid
leaving the microphone in the open sun or
in areas where temperatures exceed 110° F
(43° C) for long periods of time. Extremely
high humidity should also be avoided.
The microphone can be easily attached to a
tie, lapel, dress or other clothing using the
included clip.
The provided foam windscreen simply slips
over the head of the microphone, effectively
reducing wind noise and “popping” when used
extra close.
Output is low impedance balanced. The
output connector of the power module mates
with XLRF-type cable connectors. The
balanced signal appears across Pins 2 and 3,
The microphone shall be a fixed-charge
condenser with a frequency response of 30
Hz to 20,000 Hz and a cardioid polar pattern
with uniform 120° angle of acceptance. It shall
be capable of accepting optional interchangeable elements for additional polar patterns. It
shall operate from an external 11V to 52V DC
phantom power source. It shall be capable of
handling sound input levels up to 138 dB with
a dynamic range of 109 dB. Nominal opencircuit output voltage shall be 10.0 mV at
1 kHz, 1 Pascal. Output shall be low impedance balanced (250 ohms).
The microphone shall have a permanentlyattached 55" (1.4 m) miniature low-noise
cable, connected to an in-line power module

containing the microphone electronics. Screw
terminal input connections in the power
module shall permit shortening of the cable
without soldering. The power module shall
include a recessed switch for low-frequency
roll-off and shall terminate in a 3-pin XLRMtype output connector.
The microphone shall be 0.92" (23.3 mm)
long with a head diameter of 0.33" (8.4 mm).
Weight shall be 0.2 oz (5 grams) without
cable. Finish shall be low-reflectance black.
Two slip-on foam windscreens, a detachable
clothing clip and a power module belt clip
shall be included.
The Audio-Technica ES943/C is specified.
