ARCHITECTS’ SPECIFICATIONS
The microphone shall be a moving coil (dynamic) type with
a frequency response of 50 to 20,000 Hz. The unit shall have
a cardioid polar characteristic. The cancellation at the sides
shall be approximately 6 dB and the cancellation at the rear
shall be 15 to 20 dB. The microphone shall be low impedance
with a rated impedance of 150 ohms for connection to
microphone inputs rated at 19 to 300 ohms. The microphone
output shall be –57.0 dB where 0 dB = 1 milliwatt per Pascal.
The microphone shall have two switches for controlling the
frequency response. The first switch is a Bass Rolloff selector
switch. One position of this switch provides a flat low frequency
response and the second position provides a gradual low
frequency rolloff. The second switch is the Mid-Range
Emphasis (presence boost) switch. One position of this switch
provides a flat mid-range frequency response and the second
position raises the level of the mid-range frequency response.
The microphone shall be equipped with an integral swivel
assembly suitable for mounting on a stand with a 5/8 in-27
thread.
The overall dimensions shall be 189.7 mm (7.469 in.) in
length, 148 mm (5.812 in.) in height, and 96 mm (3.775 in.) in
width. The weight of the microphone shall be 765.4 g (1 lb.,
11 oz.)
The microphone shall be the Shure Model SM7B or
equivalent.
