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 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 to the“MIN” position.  
Turn on the subwoofer by pressing the Power Switch 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 in the ON position, the LED on the rear  
panel 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  
All wiring connections should be inspected and cleaned or remade peri-  
odically. The frequency of maintenance depends on the metals involved  
in the connections, atmospheric conditions and other factors, but once  
per year is the minimum.  
can be left on. You may turn off the Power Switch for extended  
periods of nonoperation, e.g., when you are away on vacation.  
Adjust Level  
Turn the Subwoofer-Level Control up about halfway. If no sound

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  
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-  
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.
