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.

English
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
Turns the system power on and off.
System Volume
Adjusts the overall system volume.
Fader
Adjusts the volume level of the rear speakers.
Center
Adjusts the volume level of the center speaker.
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.

Logitech®Z-640 喇叭的安裝
重要：基於安全的理由，請先安裝系統，再接上電源。
1. 在連接纜線與重低音喇叭之前，請將兩個前方的衛星喇叭分別放在電腦螢幕的兩
邊，讓它們之間的距離與您的距離相同。讓它們面對您。
其他的衛星喇叭則放在您的後方，距離約與前方喇叭的距離相同。
將中央聲道喇叭放在您的螢幕上面，或是您的螢幕與鍵盤中間的桌面上。這個喇
叭是系統的控制中心，因此請放在您手部可及的範圍內。依照您放的位置來調整
腳架，讓聲音可以直接往您的方向傳送。如果要調整腳架，請拆下用於固定的螺
絲，將腳架反轉，然後再裝上螺絲。
為了達到最佳的音效品質，請將重低音喇叭放在桌下的地面上。請保持喇叭周圍
的通風良好。
2. 將各衛星喇叭的彩色插頭分別插入重低音喇叭背面的對應彩色插孔中。將中央喇
叭的 d-sub 插頭連接到重低音喇叭上，如上頁所示。在插入插頭之前，先仔細地
排列好接腳，然後再用螺絲固定接頭。
3. A. 如果您有 PC 及：
•6聲道音效卡：請將音源輸入纜線的彩色插頭插入音效卡上對應的彩色插孔
中。如果要聆聽 6 聲道音效卡的最佳效果，請確定沒有按下中央喇叭控制
的矩陣按鈕。
•4聲道音效卡：請將音源輸入纜線的綠色插頭插入前方的插孔中，然後將黑
色插頭插入音效卡的後方插孔中。如果要打開中央聲道喇叭的聲音，請按
下中央喇叭上的矩陣按鈕。
•2聲道音效卡：請將音源輸入纜線的綠色插頭插入音效卡上的「訊號輸出」
插孔中。如果要打開中央聲道喇叭的聲音，請按下中央喇叭上的矩陣按
鈕。如果是使用 2 聲道音效卡，便聽不到後方喇叭的聲音。
