Placing Speakers
WARNING: The subwoofer is NOT magnetically shielded, so it must be
kept at least 2 feet (0.6m) from PC monitors, TV sets, computer hard
drives, or any other magnetic media (floppy discs, computer or audio
tapes, etc.)
Arrange the satellite speakers to suit your listening tastes. The speakers
are magnetically shielded, and can be placed close to a PC monitor or
TV set without distorting the image.
The subwoofer is non-directional, so it doesn’t need to be placed in
any particular location. Putting it on the floor close to a wall or in
a corner will maximize bass efficiency and be sure to provide it with
proper ventilation.
Making Connections
WARNING: Do not insert the system’s power plug into an AC outlet
until all other connections are made. And turn off audio sources before
connecting them to the CS21’s inputs.
To ensure first-time operation as expected, please carefully follow the
connection sequence described below.
1. Connect the right satellite speaker (with a thicker cable and orange
DIN connector) to the orange input on the back of the subwoofer,
labeled RIGHT. Note that the arrow on the DIN connector must
face left.
2. Connect the left satellite speaker (with a thinner cable and a brown
3.5mm connector) to the brown input on the back of the subwoofer,
labeled LEFT.
3. Connect one end of the audio input cable (with lime green
connectors at each end) to the matching lime green input plug on
the back of the subwoofer, labeled MAIN INPUT.
4. Connect the other end of the audio input cable to your desired
audio source.
PC AUDIO
Connect the lime green audio input cable to your PC’s sound output
jack (typically colored lime green, and usually labeled “1” or “Main”),
as described in your PC/sound card documentation.
PORTABLE AUDIO DEVICE (CD PLAYER, MP3 PLAYER, ETC.)
Connect the lime green audio input cable to the line out of your
portable device (if it has one), or to the device’s headphone jack.
GAME CONSOLE (PLAYSTATION
®
2, XBOX™, GAMECUBE
®
, ETC.)
Connect the lime green audio input cable to the matching lime green
connector on the console gaming Y-adapter, then attach the other
ends of the Y-adapter (with red and white RCA connectors) to the
corresponding red and white RCA audio outputs from your game
console. Your game console documentation should help you determine
which connections to use.
Powering On
1. After all other connections are made; plug the AC power cord from
the back of the subwoofer into an AC outlet.
2. Turn on the audio source.
3. Turn on the CS21 speaker system by pushing the power button
located on top of the right satellite . Blue LED’s will light on the
front of both satellites when the power is ON.
NOTE: To avoid hearing popping sounds when you turn on your CS21
speaker system, always turn on your audio source first.
System Operation
Master Volume
Adjust the master volume using the buttons on the top of the right
satellite labeled + and –. The + button increases the volume, and
the – button decreases it.
Subwoofer Volume
Adjust the subwoofer level (and system bass response) using the
control on the back of the subwoofer labeled SUBWOOFER LEVEL.
A horizontal control position is neutral. Turn the control clockwise to
increase the bass, and counter-clockwise to decrease the bass. A high
bass level is often preferable for gaming audio or when listening at
low volume levels.
Headphones
To use headphones with the CS21, connect the headphones to the
appropriate jack on the side of the right satellite speaker. When
headphones are connected the speakers will automatically mute.
Auxiliary Input
A second audio source may also be connected to your CS21 system,
using the black 3.5mm connector on the back of the subwoofer
labeled AUX INPUT. When present, this sound will be mixed with
the main audio source.
