24C/CT Micro
Professional Series – Background Music Ceiling Speaker
SPECSHEET
Description:
The Control 24C Micro and Control 24CT Micro are
compact in-ceiling speakers, 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 and a smooth, natural frequency response
make the Control 24C/CT Micro ideal for medium
volume business music systems as well as for the
medium to low SPL segments of larger or louder
systems. 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 can, in many systems,
allow for mixing and matching of models within zones
without requiring separate equalization.
Installation of the Control 24C/CT Micro 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. A template is provided for
marking the cutout. An innovative C-shaped support
backing plate can be installed from below through the
cutout to reinforce the top of the ceiling material. Tile
bridge rails are included which can be screwed onto
the C-plate to extend support to the T-channel grid in
suspended ceiling installations. After the speaker is
fitted through the cutout, it is held securely in place via
mounting tabs which tighten onto the C-plate, if used, or
directly onto the ceiling material.
The Control 24C/CT Micro 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 24C/CT Micro trim and
baffle are paintable to match any decor.
