The MCP-90-0 is a compact, high-performance, flush-mount back-electret condenser microphone designed for discreet installation on RTS intercom keypanels. Its miniature design extends less than an inch from the panel, making it ideal for confined spaces where a traditional gooseneck is too obtrusive. The back-electret technology offers greater sensitivity and superior immunity to handling noise, while the included windscreen provides pop filtering and overload protection for enhanced audio quality.
