Technical Data Sheet
Description
The MCP-90 series microphones are phantom-powered “back-electret” miniature
condenser gooseneck microphones. The back-electret feature provides greater sensitivity, wider frequency response, and superior immunity from handling noise than
a diaphragm-electret microphone. The removable windscreen provides pop filtering, response-shaping and overload protection to further enhance the acoustic
performance of the microphone. The MCP-90 mircorphones are mechnically designed for quick, easy mounting to RTS™ keypanels and selected Audiocom®
intercoms.The frequency response is tailored for full-range sound reproduction
with natural sound pick-up optimized for close-up use. The microphones are fitted with a threaded TRS male connector that is compatible with RTS™ standard
threaded TRS female connectors. The MCP-90 series is designed to be phantom
powered with a wide voltage range of 1.5 to 9 VDC.

Architectural & Engineering
specifications
The microphone is a single-D cardioid backelectret condenser type with frequency response of 100 to 15,000 Hz.
The microphone has an output impedance
compatible with RTS™ equipment. The
output level is -44 dB (0 dB= 1mW/pascal). The microphone has a back-electret
generating element whose output will not
be appreciably affected by temperature extremes from -29°C (-20°F) to 74°C (135°F)
and/or humidity extremes. The microphone
is fitted with a threaded TRS male type connector that is compatible with RTS™
keypanels.
The RTS™ MCP-90-3 is specified.
The RTS™ MCP-90-8 is specified.
Installation
Insert the TRS end of the microphone into the threaded TRS connector. When the
threads are reached, begin turning the microphone (as a unit) in a clockwise manner until the microphone is completely screwed into the unit.
The RTS™ MCP-90-12 is specified.
The RTS™ MCP-90-18 is specified.
