Description:
The Control 24CT MicroPlus is a compact in-
ceiling speaker, providing full, high quality sound for
background music and music-plus-paging systems.
These speakers are ideally suited for a wide variety of
applications, from restaurants and specialty retail stores
to professional offices and airports. Low distortion,
a smooth, natural frequency response, and a 25W
transformer make the Control 24CT MicroPlus ideal
for medium volume business music. Low frequency
output can be augmented with the addition of one of
the Control Contractor subwoofer models. Similar mid/
high frequency voicing to other JBL Control Contractor
loudspeakers allows mixing and matching of models
within zones without requiring separate equalization.
Installation of the Control 24CT MicroPlus is quick and
easy. The loudspeaker is packaged with the backcan,
grille, support backing bracket and tile rails. In addition,
optional new construction brackets are available. The
entire installation can be accomplished without requiring
access above the ceiling.
The Control 24CT MicroPlus backcan is made of formed
steel and the speaker is suitable for use in air handling
spaces per UL2043. An attachment loop is provided on
the backcan for cabling. A seismic tab is provided as a
secondary support.
The Control 24CT MicroPlus trim and baffle are
paintable to match any decor.
