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.

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.
