Two-Way Ceiling Monitor
CIS400 — TWO-WAY CEILING
MONITOR
The CIS400 is a complete two-way bass-
reflex flush-mount loudspeaker assembly
designed for fixed installations into typi-
cal ceiling plenum spaces. Employing a
unique HF waveguide design based on
the Mackie HR824 studio monitors, the
CIS400 delivers superior dispersion and
pattern control over conventional coaxial
designs. The waveguide integrates the
HF driver with a 6.5" LF driver optimized
for smooth frequency response and
seamless transition through the cross-
over point. The result is extraordinary
acoustic performance not generally
associated with a commercial ceiling
speaker in this price range.
The CIS400 is supplied fully assembled,
complete with a sealed zinc-coated
steel backcan and cam-style installation
clamps. The metal enclosure includes
a recessed Euroblock input connector
with detachable mating plug, concealed
behind a hinged metal cover plate.
A welded tab is provided for seismic
restraint. Two steel T-Bar support chan-
nels are provided to facilitate installation
to a standard tile ceiling. Also supplied
is a steel split C-ring, which serves to
disperse the clamping pressure of the
mounting cams.
The CIS400 is supplied with an integral
70/100V line transformer rated to a maxi-
mum of 30 watts. Power is adjustable by

means of a recessed rotary switch on the
front bezel, and allows selection of 30, 15,
7.5 and 3.7 watt taps. A second recessed
rotary switch is provided to engage a
16-Ohm tap for use with low-impedance
amplifiers, or a 150 Hz high-pass filter.
The speaker assembly is shipped with a
detachable plastic cover fitted over the
transducers inside the bezel. This protec-
tive cover protects the drivers from dam-
age during installation and also serves
as a paint cover, allowing convenient
spray painting to match interior décor. A
powder-coated perforated steel grille is
supplied, and easily installed once the
desired Tap Selector and Full-Range/
High-Pass switches have been set.
The entire assembly is fully tested at the
time of manufacture and is warranted
to be free from defects in materials and
workmanship for a period of five years
from the date of purchase. The speaker
is designed for use in ceiling plenum
spaces and meets UL 1480 and UL 2043
regulations governing signaling devices
and plenum applications.
