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.
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 thread mic stand or
mounting flange.
The ES915/ML is a wide-range condenser
microphone with a MicroLine
®
polar pattern.
It is designed for quality sound reinforcement,
professional recording, television and other
demanding sound pickup applications. The
small-diameter, alternating adjustable-length
gooseneck design permits highly flexible
positioning while maintaining a smooth, wellcontoured appearance. An included custom
foam windscreen effectively reduces noise
from wind or ventilation air currents.
The MicroLine polar pattern provides
a 90º angle of acceptance. Additional interchangeable elements with cardioid (120º)
and hypercardioid (100º) pickup patterns are
available.

Gooseneck Microphone
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 common). Reassemble the adapter mount and test
the wiring.
The provided foam windscreen simply slips
over the MicroLine 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 output 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 microphone inserts directly into the XLRF-type
connector end of the adapter, while the other
end is
5
/8"-27 threaded to allow connection to
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-conductor 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 MicroLine
®
polar
pattern with uniform 90° 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
133 dB with a dynamic range of 107 dB.
Nominal open-circuit output voltage shall be
17.7 mV at 1 kHz, 1 Pascal. Output shall be
low impedance balanced (250 ohms).
The microphone shall be a small-diameter
alternating gooseneck design with an integral
adjustable-length section.The entire mechanical assembly shall operate smoothly and
quietly for positioning.

The microphone 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 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
standard
5
/8"-27 thread. A custom foam
windscreen shall also be included.
The microphone’s overall length shall be
adjustable from 18.66" (474.0 mm) to 21.42"
(544.0 mm). Head diameter shall be 0.31" (8.0
mm). The microphone weight shall be 4.8 oz
(135 grams). Finish shall be low-reflectance
black.
The Audio-Technica ES915/ML is specified.

1. Locate the center of the mounting location and mark it. Allow enough clearance to
accommodate the shock mount's flange on the desired surface and make certain there are no
physical obstructions below the desired location.
2. Using a 21/4" (57 mm) hole saw, drill the large through-hole for the shock mount.
3. Set the shock mount into the hole and mark the location of the three mounting screw
holes.
Make certain to "center" the mount in the large hole before marking the three small
mounting screw locations.
4. Using a 1/16" (1.5 mm) drill bit, drill three pilot holes for the mounting screws.
5. After installing the microphone, assure maximum shock mount effectiveness by providing
some slack in the connecting cable.
