6.1 Matrix:
This DTS mode is actually identical to DTS ES 6.1 Matrix as described above, but
by enabling this mode, the user thereby chooses always to activate the matrix
process on the SL and SR to generate the SC channel.
6.1 Matrix mode will work on Dolby Digital 5.1 streams, too. Try out this feature on
e.g. “Black Hawk Down”.
If the installation contains three rear surround channels, the 6.1 Matrix mode will
improve the surround experience on nearly all 5.1 encoded music and movie
CD/DVD discs. Also, the 6.1 Matrix mode will generate the same sound information
in the SC channel as the THX Surround EX process.
In this case, the user should enable both “DTS 6.1 Discrete” and “6.1 Matrix” under
the
config.extended surround menu.
DTS 96kHz:
DTS now offers a new format, where D/A conversion takes place at 96kHz. This is
also supported by AV100/120. The encoding resolution is also 24-bit, thus the
format is normally referred to as “DTS 24/96”. AV100/120 will automatically detect
this type of bitstream and display
96k 5.1 . No interaction from the user is necessary.
The 6.1 Matrix mode is automatically disabled and no sound comes from the SC
channel in 96kHz mode.
The “Queen: A night at the opera” DVD in DTS 24/96 demonstrates the potential of
this format.
The DTS 24/96 format is compatible in performance with DVD-Audio, but can be
played on normal DVD-video or CD players.
5.3 Dolby ProLogic II
The AV100/120 supports the new ProLogic II format, which generates surround and
centre channels from a normal stereo signal. Compared to the conventional
ProLogic, the new ProLogic II among other things offers separate SL and SR
channels with full bandwidth information.
Especially on TV-films in stereo, Prologic II can generate a near-Dolby Digital 5.1
experience.
AV100/120 supports separate music and movie modes for ProLogic II. The normal
movie mode will concentrate too much information in the centre channel when
listening to music, therefore the special music mode spreads out the music away
from the centre channel into the L & R speakers.
Thule Audio finds the music mode especially useful for some live recordings, but it is
of course a matter of personal taste, which mode is preferable.
For each input, the user can decide by default whether to use Music or Movie mode,
or to activate ProLogic II under the config.ProLogic II menu.
The surround mode can be toggled between
STEREO and Dolby ProLogic II by an
additional short push on the “SURROUND MODE” key.
5.4 PCM and analogue inputs
An analogue input is activated if the letters “ ANLG ” are indicated after the source
name, e.g. LD ANLG . A PCM input is present if a Dolby Digital or DTS stream is not
auto-detected for a digital input ( COAX or OPTO ).
An analogue or PCM input stream contains no information about the surround
