M-Audio 4230/MRP Computer Hardware User Manual


 
(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.
5.1 Cinema 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 SRS TruSurround 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.
