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 Teleconferencing
(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 is equipped with terminal block connectors. For installations
where plenum rated cable is to be used a UL rated, metal plenum junction box
All M55 mics are manufactured in white finish with 4 ft cable terminating in terminal
block connector. Several capsule configurations below.
