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.
