|Architects and engineer specifications
||The Microphone is a low profile boundary layer through table design with a cardioid polar pattern.
The Microphone is push activated for both UP and Down positions leaving only 3mm (0.12") protruding above the surface when in the retracted position.
The Microphone is engineered in high quality brass for long life and smooth action.
The Microphone has an integral eletronic module which requires a 9 - 48 volt phantom power supply. The module is fitted with filters which will wliminate all GSM frequencies from 800 - 1200MHz Impedance 200 Ohms Frequency 50Hz - 18HZ Sensitivity -37 ± 3dB @ 1 KHz (0db = 1V/Pa) THD 120dB is no greater than 1%
The Microphone connections: Audio a 2 metre (6.6ft) open ended 2 core and screen cable. The switch is a gray 2 core and screen the screen is not used. The switch is not designed as an on/off audio switch and is only for use via a DSP system for muting when the microphone is in the retracted position. Finish: Black Nextel® or Satin Nickel.
Not recommended. The CRM102-RF and the rest of the CRM line are fitted with a magnetic reed switch designed to be used for remote switching at the beginning and end of each session when the microphones are no longer in use.
The magnetic reed switch in the CRM line was not designed to be used for privacy muting. If used as a privacy mute, the far end would hear the mechanics of the microphone pushing in before the magnetic reed switch would have time to signal the DSP to mute.
Privacy muting can be achieved by using a separate TS001 button with your DSP of choice to mute electronically.
