Description
The ES915SC is a wide-range miniature condenser microphone with a
cardioid polar pattern and an integral mute switch/LED. It is designed for
quality sound reinforcement, professional recording, television and other
demanding sound pickup applications.
The small-diameter double gooseneck design permits highly flexible
positioning while maintaining a smooth, well-contoured appearance.
The ES915SC is available in the following models and lengths:
• ES915SC12: 304.8 mm (12.00")
• ES915SC15: 381.0 mm (15.00")
• ES915SC18: 457 .2 mm (18.00")
• ES915SC21: 533.4 mm (21.00")
• ES915SC24: 609.6 mm (24.00")
The microphone requires 11V to 52V phantom power for operation.
The microphone is equipped with UniGuard
which offers outstanding rejection of radio frequency interference (RFI).
The microphone's cardioid polar pattern provides a 120° angle of acceptance.
Additional interchangeable elements with omnidirectional (360°),
hypercardioid (100°) and MicroLine
An XLRM-type connector insert at the base allows the microphone to be
plugged directly into an XLRF-type panel jack or microphone cable.

The mute switch is designed to operate quietly without any mechanical
noise.
The microphone comes equipped with a two-stage foam windscreen,
a low-profile isolation mount, and a stand clamp to permit attaching
the microphone to a standard
mounting flange. The microphone is enclosed in a rugged housing with a
low-reflectance black finish.
Installation and Operation
The ES915SC requires 11V to 52V phantom power for operation.
Output 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.
The microphone can be mounted on a podium or desktop with the
included AT8474 low-profile isolation mount. Designed to be mounted
either above or beneath the mounting surface, the AT8474 firmly secures
the microphone while providing maximum attenuation of noise, shock
and vibration transmitted through the mounting surface. An AT8473 stand
clamp is also included to permit attaching the microphone to a standard
/ "- 27 or / "-16 threaded mic stand or mounting flange.

The provided two-stage foam windscreen simply slips over the element,
effectively reducing wind noise and popping.
An integral 80 Hz high-pass UniSteep
from a flat 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 traffic,
air-handling systems, etc.), room reverberation and mechanically coupled
vibrations. To engage the UniSteep

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.

1. The AT8474 mount can be mounted either above or below the
table surface.
2. Locate the center of the mounting location and mark it. Allow enough
clearance to accommodate the AT8474 mount on the desired
surface and make certain there are no physical obstructions
below the desired location.
3. Locate the three mounting screw holes and mark them.
4. Using a 1" hole saw, drill the through-hole for the microphone body.
(Note: Although a 1" drill bit will work, a hole saw provides for a cleaner
