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.

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 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.

®
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 ᕡ to the“MIN” position.
A Few Suggestions
Turn on the subwoofer by pressing the Power Switch ᕦ on the

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 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.
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

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

factors, but once per year is the minimum.

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
ᕡ
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.
