The RTS MCP-90 series microphones are phantom-powered “back-electret” miniature condenser gooseneck microphones. The back-electret feature provides greater sen- sitivity, wider frequency response, and superior immunity from handling noise than a diaphragm-electret microphone. The removable windscreen provides pop filter- ing, response-shaping and overload protection to further enhance the acoustic performance of the microphone.

The MCP-90 mircorphones are mechnically de- signed 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 fit- ted 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.
