Setting up your Logitech® Z-640 speakers
Important: For your safety, set up the system before plugging it into a power source.
1. Before attaching the cables to the subwoofer, position the two front satellite speakers on
either side of your computer monitor about the same distance from each other as from
you. Angle them to face you.
Place the other satellite speakers behind you and about the same distance apart as the
front speakers.
Position the center channel speaker on top of your monitor or on your desk in between
your monitor and keyboard. This speaker is the control center for your system, so you will
want to place it within easy reach. Depending on where you place it, adjust the stand to
direct the sound toward you. To adjust stand, remove screw holding it to satellite, reverse
stand, and replace screw.
For best sound quality, place the subwoofer on the floor beneath your desk. Be sure to
allow for adequate ventilation around it.
2. Insert the colored plug from each satellite speaker into the corresponding colored jacks
on the back of the subwoofer. Connect the d-sub plug from the center speaker to the
subwoofer as shown on the previous page. Carefully align the pins before inserting the
plug, and screw down the connector.
3. A. If you have a PC and a:
• 6-channel sound card: Connect the colored plugs from the audio input cable to
the color-coded jacks on the sound card. To hear optimal sound from your 6-
channel sound card, make sure the Matrix button on the center speaker control is
not depressed.
• 4-channel sound card: Connect the green plug from the audio input cable to the
front jack and the black plug into your sound card's rear jack. To enable sound
from the center channel speaker, depress the Matrix button on the center speaker.
• 2-channel sound card: Connect the green plug from the audio input cable to the
"line out" jack on your sound card. To enable sound from the center channel
speaker, depress the Matrix button on the center speaker. With a 2-channel sound
card, you will not hear sound from the rear speakers.

B. If you have a video game console (PlayStation®, PlayStation®2, Xbox™, or
GameCube®):
• Connect the green and black plugs from the audio input cable to the 2 stereo
mini jacks on the included video game adapter. Connect the red and white RCA
audio cables from your video game console to the RCA audio jacks to the video
game adapter. To enable sound from the center channel speaker, depress the
Matrix button on the center speaker.
4. Plug the subwoofer's power cord into an electrical outlet.
Enjoying your Logitech® Z-640 speakers
Access these controls on the center channel speaker:
Power

System Volume

Matrix
If you do not have a 6-channel sound card, use the Matrix feature to provide a soundtrack
for the center channel speaker. This feature creates sound for the center channel speaker
from the front left and right speakers.
Headphone Jack
When headphones are used with your Z-640 system, the speakers will mute
automatically for private listening. Note: The volume of your headphones is controlled by
your sound card or video game and cannot be adjusted by the system volume knob on
the center speaker. Instead, adjust the headphone volume on your sound card or video
game.
Dolby® Digital
The Z-640 speakers support Dolby® Digital sound on your PC if your 6-channel sound
card or DVD software can decode a Dolby® Digital soundtrack.
