Re: I have installed the z 640 but I get no sound at all
- Verify that all cables are plugged in correctly. Make sure the rear
and/or center/sub audio cable is plugged in to the correct port. On
most surround sound cards, the rear audio port is black, the front
audio port is green, and the center/sub audio port is orange. If you do
not have a surround sound card, make sure you obtain the proper adapter
(discussed in the next paragraph) or use surround sound emulation if
your speaker system offers it. If you are not sure if you have a
surround sound card, please check with the manufacturer of your sound
card for details.
- Make sure your sound card supports the same amount of channels as
your speaker system contains. For 4.1 systems, it should have a front
and rear speaker jack on the card. For 5.1 systems, the card should
have a front, rear, and center/sub, output. The card should be properly
installed and configured. Please contact your sound card manufacturer
for details. If you do not have a surround sound capable sound card,
you can use the M3D button on the controller unit (if you own a z-560
or z-540) or use the source selector switch (if you own a z-5300 or
x-620). If you do not have any of the models above, you can use an
adapter to split the signal for the front and rear speakers. This type
of adapter is a 3.5mm male to 2-3.5mm female jacks. You can purchase
this adapter at your local electronic store. Please refer to your
manual if you do not know if your speaker system can emulate surround
sound.
- Try connecting the speakers to a portable sound device such as a
walkman or portable CD player. Plug the speakers into the headphone
jack, but make sure the volume is lowered so the speakers are not over
powered. You can do this for both the front, rear, center/sub speakers
to verify that they work. If the speaker system works on the walkman,
then you are experiencing a configuration issue with your sound card.
Please contact your sound card manufacturer.
- Check the system Volume Control located in the System tray. Make
sure that the volumes are at a reasonable level and are not checked for
Muting.
