WARNING! This equipment has been designed to be installed
by qualied professionals only! There are many factors to be
considered when installing professional sound reinforcement
systems, including mechanical and electrical considerations, as
well as acoustic coverage and performance. LOUD Technologies
strongly recommends that this equipment be installed only by a
professional sound installer or contractor.
Occupational Safety and Health Administration (OSHA) has
established the maximum sound pressure levels that can be
with stood without causing damage, which are shown in the
table below. According to the OSHA regulations, any exposure
over the maximum limits indicated in the table can reduce the
hearing capacity of a person. To prevent potentially dangerous
exposure to high sound pressure levels, anyone subjected to such
levels must use suitable protection. When an EAW Commercial
product capable of producing high sound levels is being used, it
is therefore necessary to wear ear plugs or protective earphones
when the limits shown in the table are exceeded.
Consult the specications provided in the instruction manual to
know the maximum sound pressure (SPL) the speaker is capable
of producing.

4. INTRODUCTION
The CIS300 is a complete two-way bass-reex ush-mount
loudspeaker assembly designed for ease of installation,
extremely wide coverage, and high-delity 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 bafe 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 bafe rim and grille can be painted to
match the surrounding décor.

6. INSTALLING THE CIS300
The CIS300 can be installed into suspended or drywall-based
ceilings. The speaker is secured in place with the four rotating
mounting tabs. The support rails are used with suspended
ceilings (standard 24" spacing) to transfer the weight of the
speaker to the T-channel runners.
PLACEMENT
There are two considerations when deciding where to place
the CIS300 speakers.
Location: When installing the speaker in a suspended
ceiling with conventional ceiling tiles, the location of the
speaker is determined in part by the support grid of the
suspended ceiling system.
When installing the speaker in a drywall ceiling, the
location of the speaker is determined in part by the location of
the ceiling joists.
Coverage: It is important to locate the speakers in such
a way that the sound is evenly distributed over the entire
area. Keep in mind that the sound has farther to travel on the
outside edge of the coverage area for each individual speaker
than directly below the speaker, resulting in a decrease in SPL
at the outer edges of the listening plane. The CIS300 is –6 dB
at a horizontal off-axis angle of 70º from 1 kHz to 6 kHz (140º
coverage).
The speaker placement should be designed such that the
edges of the coverage pattern for each speaker are at least
touching. The more overlap that is provided (higher density
coverage), the more SPL the system is capable of providing and
the less variation in level as you move around the area. The
downside of higher density coverage, of course, is that more
speakers are required for a given area.
INSTALLATION
Note: Observe all local and national codes when installing the
CIS300.
1. Cut the hole for the speaker using the supplied cutout template.
If using a circular cutter, set the diameter
to 7.8 inches (199 mm).
2. Insert the C-ring (2) through the hole so the hanging
brackets on the C-ring point up. If installing in a suspended
ceiling, align the support rails (3) on either side of the hole
and hook them onto the T-channel runners in the suspended
ceiling support grid. Then slide the C-ring brackets over the
support rails as shown in the illustration below.
3. You can install the CIS300 speakers using either conduit or
plenum-approved jacketed cable.
A. Installation with Plenum-Approved Jack-
eted Cable or Flexible Conduit
Note: If you can access the back of the CIS300 once it is
mounted, you may prefer to do steps A3 and A4 before doing
steps A1 and A2.
A1.Attach the speaker cable to the supplied Phoenix-type
connector (8). This is a 4-position connector, with two “+”
and two “–” terminals. Connect the speaker cable to the
“+” and “–” terminals labeled IN. If connecting another
speaker in a distributed system (in parallel), connect the
speaker cable running to the next speaker to the “+” and
“–” terminals labeled LOOP THRU.
A2.Open the terminal cover plate (7) on the back of the
CIS300. Route the speaker cable through the strain relief
bracket (9), and connect the speaker connector (8) to the

A3.Insert the speaker into the hole all the way, so the front
bafe rim is ush against the ceiling.
B. Installation to Conduit
B1. Remove the two screws holding the strain relief (9) onto
the rear cover and remove the strain relief assembly.
4-pin terminal. Tighten the strain relief screws to secure
the speaker cable or exible conduit. Close the terminal
cover plate (7) and tighten the locking screw (7a) rmly.
B2. Open the terminal cover plate (7) on the back of the
CIS300. Use a threaded conduit set-screw coupler (not
supplied: For 1/2" conduit, use Thomas&Betts Steel City
model TC221-SC or UL listed equivalent1) and insert
into the opening exposed by removing the strain relief
assembly.
B3. Fasten the coupler to the cover using the nut supplied with
the coupler.
B4. Insert the speaker into the hole
all the way, so the front bafe rim is
ush against the ceiling.
B5. Turn the four attachment screws
(5) clockwise until tight to secure
the mounting tabs over the C-ring.
DO NOT OVERTIGHTEN.
1 This method can be used with 1/2" exible
conduit by substituting a Thomas&Betts Steel
City model XC241 exible conduit tting (or
UL listed equivalent).

B6. Pull the speaker cable through the conduit coupler and
attach to the supplied Phoenix-type connector (8). This is a
4-position connector, with two “+” and two “–” terminals.
Connect the speaker cable to the “+” and “–” terminals
labeled IN. If connecting another speaker in a distributed
system (in parallel), connect the speaker cable running
to the next speaker to the “+” and “–” terminals labeled
LOOP THRU.
B7. Close the terminal cover plate (7) and tighten the locking
screw (7a) rmly.
B8. Insert the conduit into the coupler and fasten with the set-
screw.
Note: A seismic safety tab (10) is provided to secure the
loudspeaker to the building structure with wire cabling for
additional support where required by local construction
codes. We recommend using this secondary support for
additional safety.
4. Set the Tap Selector Switch (12). Make sure all the taps
in the system add up to less than the rated power of
the amplier driving them. As a general rule, you should
provide at least 10% headroom to account for insertion
losses (i.e., wiring resistance, etc.). For example, if you
have four speakers tapped at 15 watts each, the amplier
should be rated at least 66 watts.
5. Set the Full-Range/High-Pass Selector Switch (13). For
normal operation, set the switch to the FULL RANGE
position. If a subwoofer is being used in the system to
reinforce the very-low frequencies, use the HIGH PASS
position to roll off the frequencies below 150 Hz. This
provides the added benet of making more power available
for the crucial mid and high frequencies.
If the speaker is being used in a low-impedance system,
use the FULL RANGE (16 OHM) position. This
bypasses the tapped transformer.
6. Install the grille (1) by pressing it into place until the front
of the grille is ush with the front bafe rim. It is important
that the grille be securely seated to avoid having it vibrate
loose.
