PLACEMENT
Left and Right Front Channels
For left and right front channels, place one satellite to the left
and another to the right of the television, as shown in Figure 1.
Since the speakers are magnetically shielded, you can place
them very close to the TV without worrying about the magnetic
field distorting the picture.
Center Channel
For the center channel, place the speaker directly on top of,
or below, your television. Use a shelf or one of the included wall
brackets if the television does not provide a stable platform.
Surround Channels
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. The surround speakers should be mounted at a height of
between 5 ft. (1.5m) and 7 ft. (2m).
Subwoofer
Since the installation of a subwoofer can be somewhat more compli-
cated than installing full-range speakers, it is essential that you read
this section very carefully prior to connecting the subwoofer to your
system. Should you have questions relating to installation, it is advis-
able to call either your dealer or JBL’s Customer Service Department
for advice.
The performance of the subwoofer is directly related to its placement
in the listening room and how the subwoofer is aligned with the
satellite speakers. Setting the volume of the subwoofer in relation
to the left and right speakers is also of critical importance because
it’s essential that the subwoofer integrate smoothly with the entire
system. Setting the subwoofer’s volume level too high will result in
an overpowering, boomy bass. Setting the volume level too low will
negate the benefits of the subwoofer.
Here are several additional facts on installation that may prove use-
ful. It is generally believed that low frequencies (below 125Hz) are
nondirectional and, therefore, placement of a subwoofer within any
listening room is not critical. While in theory it is true that the larger
wavelengths of extremely low frequencies are basically nondirec-
tional, the fact is that, when installing a subwoofer within the limited
confines of a room, reflections, standing waves and absorptions gen-
erated within the room will strongly influence the performance of any
subwoofer system. As a result, specific location of the subwoofer
becomes important, and we strongly recommend that you experiment
with placement before choosing a final location. Placement will
depend upon your room (for example, whether or not your room
permits placement of the subwoofer near either satellite) and the
amount and quality of bass required.

WALL MOUNTING THE SATELLITES
AND CENTER CHANNEL
The CS480 satellites and center channel are designed to be mounted
on the wall. There is a fixed-mount wall bracket and an adjustable
wall bracket provided for each satellite and the center channel. Each
speaker bracket will require up to four 1-1/2"#10 wood screws; each
screw should be fastened to a wall stud. If a wall stud is unavailable,
install an anchor appropriate for a 1-1/2"#10 screw.
Step 2. Mark the positions on the wall where you would like to place
the mounting screws.
Step 3. Place the bracket against the wall and fasten four 1-1/2" #10
wood screws (not included) through the bracket’s screw holes into
the wall. If a wall stud is not available, use an appropriate anchor.
NOTE: The customer is responsible for the correct selection
and use of mounting hardware (available through hardware stores)
that will ensure the proper and safe wall-mounting of the speakers.
Fixed-Mount Wall Bracket
Step 1. Mark the positions on the wall where you would like to
place the mounting screws.
Step 2. Attach the bracket to the wall using two screws
(not included).
Step 4. Unscrew the round collar (C) from the bracket (A).
Step 3. Remove the rubber ring on the bottom of the satellite and
seat the satellite or center channel speaker onto the back bracket.

Step 4. Attach the 1/4-20 screw into the insert on the bottom of the
speaker and tighten.
Step 5. Screw the ball and shaft assembly (B) to the 1/4"-20 insert on the
back of the satellite or the center channel (do not use the bottom insert
on either speaker). Back out 1/2 of a turn and tighten the nut against the
speaker. If the ball and shaft assembly is not backed out before tighten-
ing the nut, performing Step 8 below may dislodge the threaded insert in
the speaker housing and permanently damage the speaker.
Step 6. Attach the speaker wire as shown on page 7.
Step 7. Drop the round collar (C) over the ball and shaft assembly
(B) that is mounted to the speaker with the finished side of the collar
facing the rear of the speaker.
Step 8. Carefully push the ball straight into the socket mounted on the
wall, angle the speaker as desired and tighten the collar using the
enclosed metal bar.

CONNECTIONS
Observe polarities when making speaker connections, as shown
in Figure 5. Connect each + terminal on the back of the amplifier or
receiver to the respective + (red) terminal on the speaker. Connect
the – (black) terminals in the same way.
Turn Off All Power
After placing the speakers, you are ready to connect your system.
First, turn off all audio-system power. Use high-quality speaker wire
to make your connections (#18-gauge speaker wire with polarity
coding is included). For longer distances, #16-gauge or heavier wire
is recommended. 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.
Important!
Do not reverse polarities (i.e., + to –, or – to +) when making
connections. Be certain that positive and negative wire strands are
completely isolated to avoid short circuits that may damage your
equipment.
NOTE: On certain models using hexagonal terminal nuts, a small
socket wrench is provided to help in properly tightening the terminals.
Hand-tighten only and do not overtighten.
Satellites
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.
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.
Figure 4. Wiring diagram shows polarity connections
for one channel of a home theater system.
Figure 5. The satellites and center channel
speaker feature terminals that can be connected
in several different ways – e.g., spade terminals
and direct wiring (as shown here).

OPERATION
Surround Modes
Phase Control
When using the CS480 in a Dolby Digital or DTS home theater system,
make sure all speakers are set to “Small”. In a Dolby Pro Logic home
theater system, make sure the receiver’s center channel mode is set
to “Normal.”
The Phase Switch ᕢ determines whether the subwoofer speaker’s
pistonlike action moves in and out with the main speakers (0˚) or
opposite the main speakers (180˚). Proper phase adjustment depends
on several variables such as room size, subwoofer placement and
listener position. Adjust the phase switch to maximize bass output at
the listening position.
®
Some Dolby Digital-equipped receivers/processors offer different
setup options for each source or surround mode (e.g., CD-stereo,
videotape, Dolby, Pro Logic). In each case, follow your equipment’s
instructions to ensure that the subwoofer output is turned on and that
the speakers are set to “Small” in each mode.
Final Positioning
After correctly connecting the CS480 system and verifying that both the
subwoofer and all satellite speakers are playing, it is time to optimize
the system for your particular listening room. Earlier, you placed the
subwoofer in its general location. Finding the exact location for optimum
performance sometimes only involves moving the speakers up to a
few inches in any direction. We urge you, therefore, to experiment
with placement, if possible, until your speakers deliver their full
potential.
Power On
Plug your subwoofer’s AC cord into a wall outlet. Do not use the outlets
on the back of the receiver.
Initially set the Subwoofer-Level Control ᕡ to the“MIN” position.
Turn on the subwoofer by pressing the Power Switch ᕦ on the
rear panel.
A Few Suggestions
We recommend that you do not operate your speakers or subwoofer with
the bass, treble and loudness controls set to full boost. This will place
undue strain on your electronics and speakers, and could damage them.
Turn on your entire audio system and start a CD or movie soundtrack
at a moderate level.
The volume control setting on your processor/preamp or receiver is not a
specific indication of the overall loudness level of the speakers. The only
important consideration is the loudness level at which the system can be
played, regardless of where the volume control is set.
Auto On/Standby
With the Power Switch ᕦ in the ON position, the LED on the rear
panel ᕥ will remain lit in green or red to indicate the ON or STANDBY
mode of the subwoofer.
Always turn down the volume control setting on your processor/preamp
or receiver when changing sources, or switching inputs to AM or FM
operation. Excessively loud transients (clicks or popping sounds) can
damage the satellite speakers and possibly the subwoofer.
RED = STANDBY (No signal detected, Amp Off)
GREEN = ON (Signal detected, Amp On)
Maintenance and Service
The satellite and subwoofer enclosures may be cleaned using a soft cloth
to remove fingerprints or to wipe off dust.
The subwoofer will automatically enter the Standby mode after
approximately 10 minutes when no signal is detected from your
system. The subwoofer will then power on instantly when a signal

is detected. During periods of normal use, the Power Switch

can be left on. You may turn off the Power Switch for extended
periods of nonoperation, e.g., when you are away on vacation.

emanates from the subwoofer, check the AC-line cord and input
cables. Are the connectors on the cables making proper contact? Is
the AC plug connected to a “live” receptacle? Has the Power Switch
ᕦ
been pressed to the ON position? Once you have confirmed that
the subwoofer is active, proceed by playing a CD or DVD. Use a
selection that has ample bass information.
Set the overall volume control of the receiver/processor to a comfort-
ᕡ
able level. Adjust the Subwoofer-Level Control until you obtain
a pleasing blend of bass. Bass response should not overpower the
room but rather be adjusted so there is a harmonious blend across
the entire musical range. Many users have a tendency to set the
subwoofer volume too loud, adhering to the belief that a subwoofer is
there to produce lots of bass. This is not entirely true. A subwoofer is
there to enhance bass, extending the response of the entire system
so the bass can be felt as well as heard. However, overall balance
must be maintained or the music will not sound natural. An experi-
enced listener will set the volume of the subwoofer so its impact on
bass response is always there but never obtrusive.
