CIS400 TWO-WAY CEILING MONITOR
THAT WAS THEN. THIS I S EAW.
www.eaw.com
FEATURES
• 6.5" cast steel basket, high-efficiency carbon fiber woofer
• 110º x 110º constant directivity horn with Ferrofluid® cooled,
1" Neodymium dome tweeter
• Built-in LICC low-inductance passive crossover with high
frequency dynamic protection
• Lightweight, UV/weather resistant, high density polystyrene
• Integrated mounting system and hardware included
• UL/cUL/CE listed
DESCRIPTION
The CIS400 is a complete two-way bass-reflex flush-mount
loudspeaker assembly designed for fixed installations into typical
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 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 speaker assembly is shipped with a detachable plastic cover
fitted 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 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.
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
amplifiers, or a 150 Hz high-pass filter.
