CONNECTION TIPS
aimed toward the listening area.
STEREO
Before deciding where to place your speakers, survey your room and think
about placement, keeping the following points in mind, and using Figure 1,
on previous page, as a guide:
• For best results, place the speakers 6'–8' apart.
• Refer to “Home Theater” below if you also plan to use the speakers in
a home theater system.
HOME THEATER
For front-channel use, place one speaker on the left and another on the
right along either side of the television.
A center channel speaker should go directly above the television. For left
and right surround channels, place one speaker on the left and another
on the right, to the side of or slightly behind the listening area. In 6- or
7-channel configurations, place the rear channel(s) behind the listening
position, as shown in Figure 3.
NOTE: A JBL powered subwoofer will add impact and realism to both
music and film soundtracks. Contact your JBL dealer for recommendations
on subwoofer models for your application.
Proper placement of the speakers is an important step in obtaining the most
realistic soundstage possible. These recommendations are for the optimal
placement of the loudspeakers. Use these placement recommendations as
a guide. Slight variations will not diminish your listening pleasure.

NOTE: The LS360C in-ceiling speaker was designed to be easily installed.
However, if you are unable to clearly and fully understand and follow the
instructions in this manual, or if you are unsure of your ability to properly
install these loudspeakers, please contact your dealer or a qualified installer.
TURN OFF ALL POWER
Before completing the installation, you must connect your speakers to your
system. First, turn off all audio-system power. Use high-quality speaker wire
to make your connections. Use at least #16-gauge speaker wire with polarity
coding. Heavier-gauge wire is recommended for larger distances. Consult the
chart above or your dealer for recommendations. The side of the wire with a
ridge or other coding is usually considered positive (+) polarity. Also, consult
the owner’s manuals that were included with your amplifier or receiver to
confirm connection procedures.
TOOLS NEEDED
Pencil
Phillips #2 screwdriver
(Do not use a powered screwdriver
of any kind)
Observe polarities when making speaker connections, as shown in Figure 4.
Connect each + terminal on the back of the amplifier or receiver to the
respective + (red) terminal on each speaker. Connect the – (black) terminals
in the same way.
Measuring tape
Utility knife
IMPORTANT!
Do not reverse polarities (i.e., + to – , or – to +) when making connections.
Doing so will cause poor imaging and diminished bass response. Be certain
that positive and negative wire strands are completely isolated to avoid short
circuits that may damage your equipment.

3. NOTE: Always allow at
least a 1/2 inch between
a ceiling stud/joist and the
speaker cutout, or the
locking tabs will not be
able to swivel into place.
1. Remove the plastic paint
shield from the speaker frame.
2. Determine the correct
speaker location.
NOTE: Use the included
template when cutting the
drywall.
4. Ensure that the drywall or plywood
board or other appropriate wallboard
is at least a 1/2-inch thick, and confirm
that the board material is capable of
withstanding the weight of the speaker
you will be installing. Cut the drywall.
7. Screw down each of the four
Phillips-head screws, alternating
between the four screws. The
locking tabs will swivel into
place and secure the unit to the
rear surface of the ceiling. Hand-
tighten with a nonpowered,
straight-handle regular screw-
driver only. Do not use a socket
wrench, a powered screwdriver,
a drill or any other powered tool.
Confirm that the speaker is firmly
and securely held in place and
that all four locking tabs are firmly
resting against the ceiling.
5. Connect the speaker wires to
the speaker. It is recommended
that the nylon cable-strain
relief tab, located next to the
speaker terminals, be used
to help prevent the speaker
wires from being accidentally
dislodged (see Figure 5, below).
6. Make sure all four locking tabs
are properly positioned against
the locking tab stops that are
located on the speaker frame (see
Figure 6, below). After confirming
this, carefully place the frame
assembly in the ceiling and con-
firm that there is no more than
1/8-inch play between the frame
and the ceiling cutout. After posi-
tioning the speaker in the mounting
location, back each screw out one
full turn (turn counterclockwise).
8. Attach the metal grille
and logo, if desired.

NEW CONSTRUCTION
If you wish to preinstall a rough-in frame before the drywall is installed,
you will need to purchase the RIF10C rough-in-frame. Detailed installation
instructions are supplied with the rough-in kit.
PAINTING THE SPEAKER
FRAME AND GRILLE
The LS360C in-ceiling loudspeaker can be painted to match any décor.
If you wish to change the color, the satin finish on the grille and frame will
function as a primer coat. Before painting, install the paint shield (inner
section of template in the assembly kit) securely into the recess in the baffle.
This will protect the speaker components and baffle from paint residue. Use
a high-quality spray paint, and apply a thin coat of color. Be certain the grille
perforations remain free of paint. Filling them with paint will diminish the
sound quality.
NOTE: Gently remove the acoustical foam blanket from the grille before
painting. Reattach the blanket after the paint has dried.
OPERATION
SURROUND SETTINGS
®
®
When using the system in a Dolby Digital or DTS home theater system,
make sure all speakers are set to “Small.”
Some Dolby Digital-equipped receivers/processors offer different setup
options for each source or surround mode: e.g., CD-stereo, videotape, Dolby
®
or Pro Logic . In each case, follow your equipment’s instructions to ensure that
the subwoofer (if you have one) output is turned on and that the speakers are
set to “Small” in each mode.
TWEETER-LEVEL CONTROL
In most typical listening rooms, this switch should be left in the neutral or
“0” position. This setting will deliver the most neutral and balanced sound.
In some extreme cases, it may be desirable to slightly boost or cut the
tweeter’s output, depending upon the room layout, construction and
furnishings.
If the room is sparsely furnished, contains large exposed windows or is
otherwise very reverberant, you may want to set the control to the “–”
(–1.5dB) position. If the room is exceptionally absorbent because it is well
furnished or has thick curtains and/or carpet, you may want to increase
the tweeter output by setting this switch to the “+” position (+1.5dB).
Of course, the control may be set to either position, based on listener
preference.
BOUNDARY COMPENSATION CONTROL
This control is designed to be engaged when positioning the loudspeaker
within two feet of another surface to eliminate the bass peak caused by
the second surface and to maintain a smooth, natural bass response. For
example, if you need to install your in-ceiling speaker within two feet of a
side wall or corner, it is recommended that the Boundary Compensation
control be set to the “On” position. In all other installations, the control
should typically be set to “Off”. Of course, the control may be set to either
position, based on listener preference.
