If only two audio channels are active in the received Dolby Digital bitstream (2/0), the
input is assumed to be Dolby ProLogic II, if indicated in the bitstream, otherwise as
two channel stereo.
In case of only two audio channels are active, the user can toggle between
STEREO
and
Dolby ProLogic II
by an additional short push on the “SURROUND MODE” key.
In this case both the Dolby Digital and Stereo or the Dolby Digital and Dolby
ProLogic II indicators are turned on. See further information about ProLogic II below.
The normal display returns after 15 sec. from last push on “SURROUND MODE” or
by pushing the ”>VOL” key.
5.2 DTS
Generally DTS offer the same information and possibilities as described above for
Dolby Digital. But DTS also contains additional possibilities as described in the
following.
Several new DTS formats are supported:
DTS 24bit:
The DTS encoding resolution is indicated at DTS lock on, second line. E.g.
768k/24
means a 768kHz transmission bitrate with a 24bit encoding resolution.
PR350 B offer extended precision decoding of DTS 24bit stream to take full
advantage of this increased resolution. This improves dynamic range for DTS 24bit
of up to 117dBA, which is fully comparable with DVD Audio. But DTS 24bit stream
can be played on normal DVD Video players. Several mainstream DVD Video disc’s
are already encoded with DTS 24bit, e.g.: “Pearl Harbour”, “Jurassic Park III”,
”Gladiator”, “Bowfinger” and “The Haunting”.
DTS ES 6.1 Discrete and DTS ES 6.1 Matrix:
Some DTS disc’s are encoded with a discrete center surround channel, called “6.1
Discrete”. If such DVD disc’s are played, PR350B will indicate
ES 3/3.1
at lock on.
This means three front channels (L, C, R) and three surround channels (SL, SC, SR)
are present in the DTS stream. If “6.1 Discrete” is enabled under the
config.extended
surround
menu, the PR350B will automatically activate the extended surround
channel, SC.
Examples of DTS ES 6.1 Discrete DVD disc’s are “Gladiator” and “The Haunting”.
A few other DVD disc are encoded with DTS ES 6.1 Matrix, where the extended
surround channel, SC is generated by a matrix process on the surround channels,
SL and SR.
An example of DTS ES 6.1 Matrix disc is “Terminator II, special edition”.
