EAW CIS400 User manual

Part No. 0009734 Rev. E 07/07
DESCRIPTION
The CIS400 is a complete two-way bass-reex ush-mount
loudspeaker assembly designed for xed installations into typical
ceiling plenum spaces. Employing a unique HF waveguide design,
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 crossover 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 channels 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 maximum of 40 watts. Power is adjustable by means of a
recessed rotary switch on the front bezel, and allows selection of 40,
20, 10 and 5 watt taps. A second recessed rotary switch is provided
to engage a 16-Ohm tap for use with low-impedance ampliers, or
a 150 Hz high-pass lter.
The speaker assembly is shipped with a detachable plastic cover
tted over the transducers inside the bezel. This protective cover
protects the drivers from damage 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 ve 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.
