switch allows selection of flat or low-roll-off response.
Enclosed in a rugged die-cast case and protected by
two layers of sturdy perforated steel, each microphone
has a field-replaceable element and low-reflectance
black finish. The combination of heavy case and rubber
non-slip bottom pad minimizes mechanical coupling of
surface vibrations to the microphone. The ES961 is also
available in white as the ES961W.
The ES961 is supplied with a 25' (7.6 m)
output cable terminating in TA3F and XLRM-type
connectors.
The ES961P has a 1/4" TRS phone plug built into its
underside, allowing for quick and easy mounting and
removal.
The ES961 and ES961P are wide-range
condenser microphones with unidirectional polar
patterns. They are designed for surface-mounted
applications such as high-quality sound reinforcement,
professional recording, television and teleconferencing.
Positioning a properly designed unidirectional
microphone centrally on a large, flat, unobstructed
surface yields several distinct advantages.The directionality is increased by 3 dB, promoting enhanced gain
before feedback and further suppression of ambient
noise. Sensitivity is increased for improved signal to
noise ratio. Phase distortion due to reflected sound
energy from the boundary itself is eliminated.
The ES961 and ES961P require 9V to 52V DC
phantom power for operation. A built-in recessed

Description

Engineered Sound
The ES961 can be mounted to a flat surface using
two panhead screws 1.88" (47.8 mm) apart, in
conjunction with the keyhole slots on the microphone’s underside. Simply remove the small cut-out
section of the rubber pad to reveal the keyhole slots
and the low-frequency roll-off switch.
ES961P The ES961P’s output is low impedance
balanced. The balanced signal appears across the tip
and ring of the 1/4" TRS plug, while the ground
connection is to the plug’s sleeve. Output is phased so
that positive acoustic pressure produces positive
voltage at the plug’s tip.
The ES961P can be plugged directly into
a mating 1/4" TRS jack.The jack should be installed with
its top edge just flush with, or slightly below, the
mounting surface. Because there can be some variation
in the jacks used, try the mounting method on scrap
material for proper fit before drilling finished cabinetry.
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 symmetry and area of the mounting
surface directly affect the sensitivity of the boundary
microphone at low frequencies. Ideally, the mounting
surface should be circular; however, square or rectangular surfaces are most often used. If the mounting
surface is rectangular, the smaller dimension tends to
determine low-frequency cutoff. The microphone
should be centered on the surface and positioned with
the front of the microphone facing the sound source
along the longer dimension of the mounting surface.
The sound source should not be below, or higher than
60° above, the plane of the mounting surface.
ES961 The ES961’s output is low impedance balanced.
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.
