Architects and engineer specifications The condenser microphone is of a very low profile boundary layer through table design, with a cardioid polar pattern. 2 Independently powered microphone capsules are inbuilt into the housing. The Microphone is motor driven and has the ability to automatically retract leaving only 2mm protruding above the surface. The integral motor requires the control module ARM-C to operate. A control signal (+2.5V - 12V) from a DSP or Electronic Switch are required to activate the RETRACTA. The microphone is of a robust brass construction and includes 2 metres (6.6ft) of cable. Included is an integral phantom power module which requires 9 to 48 volts. The phantom power module also includes filters which will eliminate all GSM frequencies from 800-1200 MHz Impedance 200 Ohms; Frequency response 50 Hz to 18 KHz; Sensitivity -37dB ± 3dB @ 1KHz (0dB =1V/Pa); Total Harmonic Distortion (THD) at an operating level of 125dB is no greater than 1%. Finish: Black Nextel® or Satin Nickel.
