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.
ARCHITECTS AND ENGINEERS SPECIFICATIONS
The microphone shall be a fixed-charge condenser designed for
suspended installation in permanent applications. It shall have 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 be capable of handling sound input levels up to
123 dB with a dynamic range of 102 dB. Nominal open-circuit
output voltage shall be 17.7 mV at 1 kHz, 1 Pascal. Output shall
be low impedance balanced (200 ohms).
The microphone shall operate from an external 11V to 52V DC
phantom power source. It shall offer outstanding rejection of radio
frequency interference (RFI). The microphone shall be RoHS compliant.
The microphone shall have a permanently attached 50' (15.2 m)
miniature low-noise cable. Its free end shall connect to a provided
plate power module via a TA3F-type connector. An optional crimping
tool and crimp sleeves shall allow for shortening of the cable
without loss of RFI immunity.
The plate power module shall be designed to mount over a standard
single gang metal electrical box for ceiling or wall mounting. The
power module shall be provided with a switch for low-frequency
roll-off. The low-frequency roll-off shall be a tailored roll-off at 80
Hz to minimize pickup of unwanted mechanical noise. In addition,
the power module shall incorporate a switchable +10 dB gain
setting. The power module face plate shall be semi-gloss white
and mounting screws shall be included.
Output connections on the power module shall be screw terminals.
For suspended installations, the microphone shall be provided
with an adjustable steel wire hanger. The steel wire hanger shall
attach to the microphone body and allow for the positioning of
the microphone without the need for tools. Microphones using
goosenecks or other methods for positioning shall be
unacceptable. A foam windscreen shall be provided.
The microphone shall be 5.77" (146.5 mm) long with a head diameter
of 0.31" (8.0 mm). The microphone weight shall be 0.3 oz
(9.5 grams) without cable. The microphone case, cable and steel
hanger shall be finished in black [white].
The Audio-Technica ES933PMML [ES933PMWML] is specified.
