The microphone shall be a back-electret con-
denser type with a wide-range uniform fre-
quency response of 20 Hz to 20 kHz. The mi-
crophone shall have an output level of 10 mV/
Pa. The microphone shall be of a single capsule,
single membrane design. The microphone shall
have an impulse response with the rise time no
longer than 25 microseconds, and total settling
time, including the rise time, no longer than 120
microseconds. The microphone shall have po-
lar characteristics uniform in all planes to form
either a cardioid or hypercardioid of revolu-
tion. Response at any angular position up to
90° away from the major axis within frequency
range from 500 Hz to 16 kHz shall deviate by
no more than ±3 dB from the ideal cardioid or
hypercardioid pattern as described by the fol-
lowing equation: SPL(a)=20*Log(1/2+cos(a)/2)
(dB), where a is the angle in radians between
the measurement source position axis and the
major axis. The microphone shall accept sound
pressure levels up to 139 dB producing no more
than 3% THD. Overall length above the XLR
connector shall be 12.5 in. (31.8cm) long for
FM360, 18.3 in. (46.5cm) long for the FM500.
The maximum head diameter shall be 1.0 in (25
mm). The microphone shall be terminated with
a professional gold-plated 3 pin XLR connector.
The microphone shall include an external wind-
screen. The microphone shall require 24-48V
phantom power. The microphone shall be made
of metal with black nish. The microphone shall
have its entire exible portion encased in black
vinyl. The Earthworks FM360, FM500 or FM360/
HC, FM500/HC is specied.
