EAW CIS961 Specifications

DESCRIPTION

The CIS961 ceiling loudspeaker features a powerful 3-way design
that provides exceptional performance, especially in high ceiling,
large-space applications. The CIS961 (60-degree by 60-degree
dispersion) incorporates four 5.25-inch LF cone woofers, four 4-inch
MF cone woofers and a 1-inch-exit HF compression driver mounted
on a large horn that foster superior pattern control. The application
of proprietary frequency shading techniques facilitates the eight
cone woofers working together to provide LF output and impact
equal to that of a 12-inch LF woofer.

The CIS961 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 that allows
selection of 128-, 64-, 32-, and 16-watt taps at 70 volts, and 128-,
64-, and 32-watt taps at 100 volts. In addition, the transformer can
be bypassed, presenting an 8-ohm load to low-impedance systems.

CIS961

3-Way High-Output Ceiling Loudspeaker

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
screw terminal block is also present. Mounting is accomplished
using the integral eyebolts on the rear to suspend the loudspeaker
with optional, adjustable, wire rope rigging. A cable clamp secures
the incoming loudspeaker cable.
