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 1.5m (5 ft.) and 2m (7 ft.).  
Subwoofer  
Since the installation of a subwoofer can be somewhat more  
complicated 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 advisable 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  
useful. 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  
nondirectional, the fact is that, when installing a subwoofer within  
the limited confines of a room, reflections, standing waves and  
absorptions generated 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 CS680 satellites and center channel are designed to be mounted  
A
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.

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.  
.
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 tightening the nut, performing Step 8 below may dislodge the  
threaded insert in the speaker housing and permanently damage the  
speaker.  
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 3. Remove the rubber ring on the bottom of the satellite and sit  
the satellite or center channel speaker onto the back bracket.  
Step 4. Attach 1/4-20" screw into insert on bottom of speaker  
and tighten.  
Step 6. Attach speaker wire as shown on page 6.  
Step 7. Drop round collar (C) over 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.

Adjustable Wall Bracket  
Step 1. Remove cap over threaded insert on rear of speaker.  
Step 2. Mark the positions on the wall where you would like to place  
the mounting screws.  
Step 3. Place bracket against the wall and fasten four 1-1/2" #10  
wood screws through the bracket’s screw holes into the wall. If a  
wall stud is not available, use an appropriate anchor.

CENTER AND SATELLITE SPEAKER CONNECTIONS  
Turn Off All Power  
Center Channel  
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 (i.e., +). Also, consult the  
owner’s manuals that were included with your amplifier or receiver  
to confirm connection procedures.  
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.  
Important!  
Do not reverse polarities (i.e., + to –, or – to +) when making con-  
nections. Be certain that positive and negative wire strands are  
completely isolated to avoid short circuits that may damage your  
equipment.  
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.  
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.  
Important!  
Do not reverse polarities (i.e., + to –, or – to +) when making con-  
nections. 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 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).

Phase Control  
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.  
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.”  
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 CS680 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.  
A Few Suggestions  
Turn on the subwoofer by pressing the Power Switch on the

place undue strain on your electronics and speakers and could  
damage them.  
rear panel.  
Turn on your entire audio system and start a CD or movie soundtrack  
at a moderate level.  
Auto On/Standby  
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.  
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.  
RED = STANDBY (No signal detected, Amp Off)  
GREEN = ON (Signal detected, Amp On)  
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.  
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.  
All wiring connections should be inspected and cleaned or remade  
periodically. The frequency of maintenance depends on the metals  
involved in the connections, atmospheric conditions and other  
factors, but once per year is the minimum.  
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  
comfortable 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 experienced listener will set the volume of the subwoofer  
so its impact on bass response is always there but never obtrusive.
