INFORMATION TAB

The information tab provides detailed information about your sound card. This includes the model number for your product and software version information.

Using 4 or 5.1 channel surround speakers your Acoustic Edge™ sound card can deliver true multi-channel surround sound from a compatible soft-DVD player application even if the player only supports stereo output. If the soft-DVD player is capable of providing a true 5.1 Dolby Digital or a 4 channel Dolby Digital™ down- mix Acoustic Edge will output all 4 or 5.1 Dolby Digital channels. Even if the soft- DVD player supports 4 or 5.1 channel Dolby Digital™ you may prefer using QMSS™ playback of DVD’s because of the enhanced rear channel content it provides. If you have only stereo speakers Acoustic Edge can also provide virtual surround using its QSurround feature.

To enable 4 or 5.1 speaker QMSS™ DVD enhancement:

1.Make sure “4 Speakers” or “5.1 Speakers” (and "Expand All" for Windows® 2000) is selected in the Acoustic Edge control panel settings tab.

2.Open the “control panel” or “settings” menu for the soft-DVD player.

3.Select the menu or tab that controls the player’s audio settings.

4.Look for a panel that allows you to select the number and type audio channels

5.Select either 2 speaker “Stereo” or 2 speaker “Dolby Surround or ProLogic”. Either option will work well as the QMSS™ DSP algorithm does not depend on Dolby encoding. (Effectively you should follow the soft-DVD player instructions for playing back over stereo speakers even though you have a quad or 5.1speaker system connected).

6.Close the control panel and play a DVD. Acoustic Edge will detect that it is in 4 or 5.1 speaker mode but is only receiving two channels of audio from the DVD and automatically generate 4 or 5.1 distinct channels of surround sound using QMSS™.

To enable a 4 or 5.1 speaker Dolby Digital™ playback :

1.Make sure “4 Speakers” or “5.1 Speakers” is selected (and for Windows® 2000 that "Expand All" is NOT selected) in the Acoustic Edge control panel settings tab.

2.Follow the soft-DVD players instructions for 4 or 5.1 speaker playback. (Some players will not offer this feature)

3.Play a DVD and Acoustic edge will output the 4 or 5.1channel Dolby Digital sound provided by the soft-DVD player.
