T h e E S 9 4 5 i s a w i d e- r a ng e
condenser microphone with an
omnidi re ct io na l pol ar pattern.
It is desig ned for u nob trus ive
table, ceiling or panel-mounted
applications for high-quality sound
reinforcement, teleconferencing,
professional recording, television
a nd oth e r d e m an d ing s ou n d
pickup applications.

U n i G u a r d ® R F I - s h i e l d i n g

outstand ing rejection o f radi o
frequency interference (RFI). The
microphone is RoHS compliant –
free from all substances specied
in the EU directive on hazardous
substances.
The microphone should be placed on a at, unobstructed mounting
surface. The smalldiameter capsule near the boundary eliminates
phase distortion and delivers clear, high-output performance.
The microphone requires 11V to 52V phantom power for operation.
The microphone is enclosed in a heavy-duty die-cast case and
protected by a two-layer steel mesh grille. The low-profile housing
has a low-reectance black nish. The microphone is also available
in white as the ES945W (shown above). Isolators are included with
the microphone for optional mechanical isolation from the mounting
surface.
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.
To mount the ES945 in a ceiling or table top without the isolators,
a 20.5 mm diameter hole is required. To mount the ES945 with the
isolators, a 23.5 mm hole is required. Place the isolators on either
side of the hole to achieve mechanical isolation from the mounting
surface.
The microphone shall be a xed-charge condenser designed for use
in table, ceiling or panel-mount boundary applications. It shall have
a frequency response of 40 Hz to 18,000 Hz and an omnidirectional
polar pattern. It shall have a self-contained power module and shall
operate from an external 11V to 52V DC phantom power source.
It shall offer outstanding rejection of radio frequency interference
(RFI). It shall be capable of handling sound input levels up to 142 dB
with a dynamic range of 112 dB. Nominal open circuit output voltage
shall be 7.9 mV at 1 kHz, 1 Pascal. Output shall be low impedance
balanced (200 ohms) from an integral 3-pin XLRM-type connector.
The microphone shall have a maximum diameter of 28.0 mm and an
overall length of 69.0 mm. Weight shall be 63 grams. The microphone
shall be housed in an all-metal case with a two-layer steel mesh
grille. Finish shall be low reectance black [white]. Resilient isolators
shall be provided for reduction of mechanical noise transfer from the
mounting panel.
Avoid leaving the microphone in the open sun or in areas where
temperatures exceed 43°C for extended periods. Extremely high
humidity should also be avoided.
