Speaker environment
Note:
these settings are disabled in versions of CyberLink PowerDVD that use Dolby
PCEE to optimize sound for media playback.
Depending on your sound card and/or number of speakers, select the speaker
environment that matches the number of speakers you have:
•
Headphone is mainly for notebook users who listen to their audio output on
headphones.
•
2 Speaker is the selection for most users playing discs on their desktop/laptop
who only have 2 speakers or a sound card that only outputs two channels.
•
The 4 Speaker selection is for computers equipped with sound cards that
support 4-ch output.
•
The 6 Speaker selection (a.k.a. 5.1 channels) is for computers equipped with
sound cards that support 6-ch output and is optimal for DVD Video titles that
feature multichannels encoding such as Dolby Digital 5.1 or DTS 5.1.
•
The 7 Speaker and 8 Speaker options are available for users who have
multiple speakers and wish to output audio to each of them.
•
The Use S/PDIF option is an advanced technological D igital I nter F ace, as
opposed to transferring signals via conventional analog interfaces, designed
by the
S ony and P hilips corporations. To enjoy true 6 speaker output quality,
you must have an external Dolby Digital or DTS decoder along with a S/PDIF-
compliant sound card to make this selection available.
Note:
when the S/PDIF audio output is enabled and the output stream is not PCM, the
volume control for CyberLink PowerDVD is disabled because your decoder assumes
the task.
•
The HDMI output selection is for users who have their audio connected with
an HDMI (High-Definition Multimedia Interface) connector.
