Using SRS® TruSurround HD™
SRS® TruSurround HD™ delivers the excitement of surround sound and enhanced movie dialog without
the need for rear speakers. In addition, it adds richness and dimension to stereo sources like music and
Internet video.
In order to experience the surround sound properly, it is important to confi rm you have the proper setup on
your PC. This section will guide you through the process of making sure you have the necessary setup to enjoy
the Z Cinéma in surround sound mode.
1. Make sure the content you are listening to was recorded in surround sound
For movies, surround sound is typically recorded using Dolby® Digital and/or DTS®. If you see one of these
two logos on your DVD, that means there a surround sound recording on your disc. Most music is not
recorded in surround (it is typically recorded in stereo), but you may have surround sound on a DVD Audio
disc or a SACD disc. Finally, many games support surround sound via the Windows® operating system.
Check with the game manufacturer to see if the game has surround sound available.
2. Make sure the application you are using supports surround sound
Every application supports surround sound differently, so there is no common instruction for this process.
For watching DVD movies in surround sound, make sure that your DVD software has a Dolby® Digital or
DTS® decoder/plugin installed (these decoders typically do not come pre-installed with the software, so
you may have to upgrade your DVD player application to unlock these features).
3. Make sure that surround sound is enabled inside the application
Once you have a surround sound decoder installed, make sure that the audio settings for your DVD
software are set to 5.1 channel surround sound. For games that support surround sound, make sure that
the audio is set to 5.1 channel surround sound from within the game settings menus.
4. Make sure the DVD is playing the surround sound recording
Some DVD movies require you to select a surround sound track from within the DVD menu. To access
these setup menus, insert the DVD movie and navigate to the main menu. Look for a settings menu or an
audio menu. Select Dolby® Digital, DTS® or whatever surround sound capability you have within your DVD
player software.
The same steps apply to watching DVD movies within Windows® Media Center. By default, Windows® Media
Center does not ship with a surround sound decoder, so you may need to purchase a separate decoder that
works with Media Center.
