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.

Make sure the lime green 3.5mm audio cable is connected and fully inserted into your PC sound output jack or other audio source.

Test the speakers on another audio source by removing the lime green 3.5mm audio cable from the audio source and connecting it to the line out or headphone jack of a different audio source (e.g., Walkman, Discman or FM radio).

Make sure the lime green 3.5mm audio cable is properly connected to the PC sound output jack (NOT “speaker-out.”) or other audio source.

Check the PC output volume level and set at mid-level.

Press the – button on the top of the right satellite to lower the volume.

Check the PC output volume level and set at mid-level.

Digital audio files (.MP3, .WAV, .MID) are often of poor quality; distortion and noise are easily noticed with high-powered speakers. Try a different audio source such as a music CD.

Move your speakers to see if the interference goes away. If not, you may be able to purchase a shielded stereo cable from your local electronics store.

Troubleshooting

Symptom Possible Problem Solution

Low hum from subwoofer.

Loud hum from subwoofer.

Not enough bass from subwoofer.

Distorted picture on PC monitor or TV screen.

The AC in your house is at 60 cycles per second, which is within the audio frequency of your subwoofer.

Bad connection.

Volume on your audio source set too high.

Check the volume on audio source.

Bad connection.

Bass setting is too low.

Subwoofer too close to PC monitor or TV set.

Some low hum may be detected when your speaker system is powered on without an audio source playing, or when the volume is set at an extremely low level.

Unplug the power cord from the surge protector (if used), and plug directly into an AC wall outlet.

Check to make sure all cables are connected properly and are making a clear connection.

Lower the volume or bass level on your PC, portable audio device, etc.

Increase the volume on the audio source.

Check to make sure all cables are connected properly and are making a clear connection.

Increase bass level on back of subwoofer.

Because the subwoofer is not magnetically shielded, it can cause distortion if it’s too close to your PC monitor or TV set. Move the subwoofer so it’s at least 2 feet from the monitor or TV set.
