4. INTRODUCTION
The CIS300 is a complete two-way bass-reflex flush-mount
loudspeaker assembly designed for ease of installation,
extremely wide coverage, and high-fidelity full-range sound
reinforcement.
The CIS300 is ideal for use in business music systems and
foreground/background music applications.
Installing the CIS300 is simple. The one-piece assembly
includes the backcan, mounting tabs (clamps), front baffle rim,
high- and low-frequency drivers, and our proprietary two-way
waveguide based on the award-winning Mackie HR824 studio
monitors. Support rails are supplied that attach to the C-ring
(included) and distribute the speaker’s weight to the ceiling tile
T-channels. A template is also included for marking the correct
cutout size.
The Phoenix-style connector on the back of the assembly
provides input and loop-through connections for 70V/100V
distribution systems, or low-impedance operation. An easily
accessible rotary switch on the front panel selects the
appropriate tap (from 3.7 watts to 30 watts). A second switch
allows you to select among full-range operation, high-pass
(when used with a subwoofer), and full-range low-impedance
operation (16 ohms).
A plastic paint shield is provided that protects the
transducers so the front baffle rim and grille can be painted to
match the surrounding décor.
