Description

The integral power module 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. A mute switch in the
base lights when the mic is “on.”
The microphone is enclosed in a rugged
housing with a low-reflectance black finish. It
features an XLRM-type connector insert at its
base, allowing it to be plugged directly into an
XLRF-type panel jack or microphone cable. In
addition to an AT8658 heavy-duty shock
mount, an AT8651 thread-mount adapter is
included to permit attachment of the XLR mic
base to a standard
5
/
8
"-27 threaded mic stand
or mounting flange.
The ES917S/C is a wide-range condenser
microphone with a cardioid polar pattern.
It is designed for quality sound reinforcement,
professional recording, television and other
demanding sound pickup applications. The
small-diameter, alternating gooseneck design
permits highly flexible positioning while
maintaining a smooth,
well-contoured
appearance. An included snap-on foam
windscreen effectively reduces noise from
wind or ventilation air currents.
The cardioid polar pattern provides a 120°
angle of acceptance. Additional interchange-
able elements with hypercardioid (100°) and
MicroLine
®
(90°) pickup patterns are available.

the cable should be 0.2" (5 mm) maximum.
Solder the conductors to the XLRF insert
using Pin 1 as ground (shield), Pin 2 as positive
(signal hot), and Pin 3 as negative (signal com-
mon). Reassemble the adapter mount and test
the wiring.
The provided snap-on foam windscreen
simply slips over the element, effectively
reducing wind noise or “popping” when used
extra close.
The small-diameter goosenecks are easy to
manipulate for proper positioning. Heavily
lubricated, they operate smoothly and quietly.
Should the unit become noisy with prolonged
use, apply a light machine oil directly on the
gooseneck area affected.
While a modern condenser microphone
is not unduly sensitive to the environment,
temperature extremes can be harmful.
Exposure to high temperature can result in
gradual and permanent reduction of the out-
put level. 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.
Output is low impedance balanced. The
output connector mates with XLRF-type
cable connectors. The balanced signal appears
across Pins 2 and 3, 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.
The microphone can be mounted on a
podium or desktop with the included AT8658
shock mount. A special isolator attenuates
noise, shock and vibration transmitted through
the mounting surface. Installation details are
provided on the back of this sheet.
The microphone can also be mounted using
the AT8651 mounting adapter. The micro-
phone inserts directly into the XLRF-type
connector end of the adapter, while the other
end is

a standard microphone desk/floor stand, or a
mounting flange on a podium or desktop. To
install: Disassemble the XLRF insert from the
adapter body. Route the mic cable (2-conduc-
tor shielded, not supplied) either through the
side hole or from the bottom of the adapter
body. If the side hole is used, the diameter of
The microphone shall be a fixed-charge
condenser with a frequency response of
30 Hz to 20,000 Hz and a cardioid polar pat-
tern with uniform 120° angle of acceptance. It
shall be capable of accepting optional inter-
changeable elements for additional polar pat-
terns. 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 open-circuit output voltage shall be
10.0 mV at 1 kHz, 1 Pascal. Output shall be
low impedance balanced (250 ohms).
The microphone shall be a small-diameter
alternating gooseneck design. It shall have
a self-contained power module with an
XLRM-type connector at the base for direct

connection to a mating XLRF-type panel jack
or cable connector. The power module shall
include an illuminating mute switch to indicate
“on” status and a recessed switch for low-
frequency roll-off. A shock mount shall be
supplied for mounting in a solid surface. An
included mounting adapter shall permit
attaching the microphone directly to a

windscreen shall also be included.
The microphone’s overall length shall be
17.44" (443.0 mm). Head diameter shall be
0.33" (8.4 mm). The microphone weight shall
be 3.8 oz (109 grams). Finish shall be
low-reflectance black.
The Audio-Technica ES917S/C is specified.
