CIS120
High-Output Ceiling-Mounted Loudspeaker
DESCRIPTION
The CIS120 is a high output ceiling-mounted coaxial loudspeaker
designed for fixed installation into high ceiling plenum spaces or
open structures. Utilizing a 12” coaxial driver, the CIS120 delivers
coherent point-source reproduction, as well as superior lowfrequency dispersion. The result is superior full-range performance in
any distributed loudspeaker system.
The CIS120 is supplied with an integral 70V/100V line transformer,
rated to a maximum of 128 watts. Tap settings are adjustable by
means of a recessed rotary switch on the front bezel, and allows
selection of 128, 64, 32, and 16 watt taps at 70V, and 128, 64, and
32 watt taps at 100V. In addition, the transformer can be bypassed,
presenting an 8-ohm load to low-impedance systems.
A sealed, painted, 18-gauge steel back can is square in shape, and
designed to mount in a 24-inch ceiling grid. The back can includes a
recessed Euroblock input connector, with detachable mating plug,
concealed behind a hinged metal cover plate. A ceramic screwterminal block is also present. Four eye-bolts fit to the back can, prior
to suspending the assembly. The baffle/can assembly is shipped with
the transducer installed. The powder-coated perforated steel grill is
easily installed once the wattage tap has been selected.
Optional installation kits include a 4-piece cable kit AC-CK for
suspension, and a 4-piece square trim ring kit AC-TRK to dress the
baffle into suspended ceiling tile surrounds.
