The microphone shall be a fixed-charge
condenser with a frequency response of
30 Hz to 20,000 Hz and a cardioid polar
pattern with uniform 120° angle of acceptance.
It shall be capable of accepting optional inter-
changeable 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
138 dB with a dynamic range of 109 dB.
Nominal open-circuit output voltage shall be
10.0 mV at 1 kHz, 1 Pascal. Output shall be low
impedance balanced (250 ohms).
The microphone shall have a permanently-
attached 50' (15.2 m) miniature low-noise
cable, connected to an included in-line power
module containing the microphone electronics.
Screw terminal input connections in the power
module shall permit shortening of the cable
without soldering. The power module shall
include a recessed switch for low-frequency
roll-off and shall terminate in a 3-pin XLRM-
type output connector.
The microphone shall be mountable in an
included adjustable steel wire hanger that
allows permanent overhead installation for
pickup of dialogue, orchestras and choirs. A
snap-on foam windscreen shall be provided.
The microphone shall be 0.92" (23.3 mm) long
with a head diameter of 0.33" (8.4 mm). The
microphone weight shall be 0.2 oz (5 grams)
without cable. The microphone case, cable and
steel hanger shall be finished in black [white].
The power module shall be finished in black.
The Audio-Technica ES933/C [ES933W/C] is
specified.
