  • 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.

    All M55 mics are manufactured in white finish with 6 ft cable terminating in terminal block conenctor. Several capsule configurations below.
    M55W - cardioid
    M55WHC - hypercardioid
    M55WS - supercardioid (shotgun)
    M55O - omnidirectional

    CONN170F - Terminal block connector, 4-ft integrated mic cable
    CONN170M - Mating terminal connector for solder-less connection
    JBM55 - Metal plenum junction box with seismic and fire safety cable restraint where required by code.

    MCHANGER  - Clear plastic clip to adjust mic angle
    WS20W - White foam windscreen to reduce wind noise
