clean and natural reproduction of both music and speech

•

Classic cardioid polar pattern, uniform with frequency and symmetrical minimum coloration of off-axis sound

•

Internal mechanical noise transmission

•

Highly effective pop filter eliminates need for any add-on protection against explosive breath sounds, even for close-up vocals or narration

•

Extremely good rejection of electromagnetic hum due to built-in hum rejection system

ARCHITECTS’ SPECIFICATIONS

The microphone shall be a moving coil (dynamic) type

a frequency response of 40 to 16,000 Hz. The unit

with have

a cardioid polar characteristic. The

cancellation at the

shall

sides shall be approximately 6 dB and the cancellation at

rear shall be 15 to 20 dB. The microphone shall be low

the 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 10 microbars.

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

148 mm (5–13/16 in.) in height, and

length,
