Architects’ and Engineers’ Specification
The microphone shall be a dynamic cardioid type, low impedance with a wide
range of frequency response, uniform from 80 to 15,000 Hz having an on/off
switch. Output level at 1 kHz shall be - 54 dB (0 dB = 1mW/10 microbars). The
polar response shall show a minimum of -15 dB at 180 degrees between 150 and
4 kHz. The woven steel screen, when attached to the microphone, shall withstand
a drop of 6 feet to a wooden floor without deformation. The microphone case
shall be die-cast zinc alloy. The microphone shall have a length of 6-3/4" ±1/32"
and a maximum diameter of 1-1/8" ±1/64". The microphone shall be finished in a
rubber textured non-reflecting black. A snap-in clamp and zippered vinyl protective
pouch shall be supplied.
The ASTATIC Model CTM 44 is specified.
