Applications
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 loud-
speaker 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 taps 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.
