The Aiphone IMU-100 Controller and Operation Station Kit is designed for seamless voice communication in security settings, featuring an acoustic tube system that delivers clear voice transmission without requiring holes in security glass for installation. Its thin acoustic tube maintains an unobstructed field of vision, while ambient noise cancelling control enhances clarity. The unit supports flexible installation options, as it can be desk mounted or installed under the counter using the supplied bracket and allows volume adjustments with a hi/lo control switch. Additionally, it includes a socket for an optional gooseneck microphone and can be mounted up to 6 feet from the MU-100 via the supplied connector.
