  • Description

    The M55 is an innovative, hanging ceiling microphone system designed for applications where aesthetics, sound quality, and ease of installation are critical. The primary applications for the ceiling mounted M55 include Video & Teleconference (VTC), distance learning, hospital rooms, surveillance and ambient room miking.

    The M55 accommodates interchangeable capsules with cardioid, hypercardioid, omnidirectional and supercardioid (shotgun) coverage patterns. All electronics are fully integrated with high sensitivity and low noise. The signal output is balanced to eliminate RF interference caused by cell phones and mobile devices.
    Installing the M55 requires drilling just one 5/8-inch hole in the ceiling, with no additional tools needed. The M55's mounting hardware easily adjusts the hanging height up to four feet from the ceiling surface without removing ceiling tiles. An optional aiming clip (MCHANGER) easily makes any additional angular adjustments. The cable assembly, with a terminal block connector, is neatly housed in an airtight, plenum-rated junction box. A wire safety cable provides additional seismic restraint.
