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.

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.
