Technical Data Sheet MCP-90-0 MCP-90-0 Low Profile Profile Low Intercom Intercom Panel Microphone Microphone Panel Architectural & Engineering Specifications Description The MCP-90-0 microphone is a phantom-powered “back-electret” miniature condenser flush microphone. The back-electret feature provides greater sensitivity, wider frequency response, and superior immunity from handling noise than a diaphragmelectret microphone. This microphone is under 3” in length and extends less than 1” from the intercom panel, lending to use in small, confined spaces without the obtrusiveness of a regular size mic. The removable windscreen (figure 1) provides pop filtering, response-shaping and overload protection to further enhance the acoustic performance of the microphone. The MCP-90 microphones 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. 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 -47 dBv / Pascal @ 1kHz. 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. Figure 1. Microphone windscreen 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. Note: To prevent damage to the microphone, finger-tighten the unit to the intercom panel. Please Contact Us Telex Communications, Inc. 12000 Portland Avenue South Burnsville, MN 55337 U.S.A.
