(Stereo) Cinema Mode: If you are using a DVD software application that only supports a 2-channel output and you wish to play a Dolby Digital or DTS movie (or DTS music CD), then choose this mode. This should also be used for sources that are encoded with Dolby Surround encoding, which is used for almost all 2- channel mix downs of movie content and some games.

5.1Cinema Mode (Windows only): This mode should only be used when the audio from the application or DVD player is providing a 5.1 channel output to the TruSurround XT software— that is, when the software can decode the multi-channel audio (this is usually the case only in “advanced” versions of DVD playback software). In the case of a Dolby Digital movie or game, if supported by the DVD or gaming software, you should select “6 Channel” or “5.1 multi-channel” as the output mode from the application (see section,“Using the Sonica With Your DVD Player”). TruSurround XT will then take this 5.1 output from the Windows application software and provide an accurate 2-channel surround virtualization.

You may adjust the Dialog Enhancement and TruBass settings according to what pleases your ears, or you may leave them as they are. Feel free to experiment with these settings while you are playing a DVD or listening to music. You may turn off these features by clicking the box and unchecking either “Enable Dialog Enhancement” or “Enable TruBass.” The following are descriptions of these additional SRSTruSurround XT™ controls and features:

SRS Dialog Enhancement: Playback of dialog often suffers because feature film soundtracks are mixed specifically for cinema playback and are loaded with the latest advancements in special audio effects. When translated over home theater or computer systems, dialog may become unintelligible. This patented SRS algorithm enhances signal clarity to address these problems, thus improving dialog intelligibility from all such source material.

TruBass: TruBass is a patented SRS technology that enhances bass performance utilizing proprietary psychoacoustic techniques.These techniques restore the perception of fundamental low frequency tones by dynamically augmenting harmonics, which are more easily reproduced by contemporary loudspeakers. Using TruBass, TruSurround XT takes the bass information contained within the original audio track and helps the speakers or headphones re- create it – even if it is below the speaker’s low frequency limitations.
