ENGLISH
ProLogic and Neo:6 are both available in various guises to decode
appropriately encoded soundtracks. Additionally DSP modes are available to
process sources with no encoding at all. Due to the matrix encoding process
none of these modes incorporate flags that tell the 551R the type of
encoding used in the source material. Thus you must manually select these
modes.
Pressing the Surround Modes button when the 551R has locked to a DD/DTS
bitstream will present more options where possible including Post-Processed
modes.
These are modes that allow extra processing to be applied after the main
surround-sound decoding. For instance Dolby Digital (2/0) + PLII Music.
Which adds a 5.1 ProLogic decode to a Stereo Dolby Digital decode to turn 2
channel stereo into 5.1.
For 7.1 Speaker setups, the number of decoding possibilities increases as
shown in the following ‘Decode modes’ tables. Several extra Post Processing
modes are available using either Prologic IIx or Neo:6.
Incoming Dolby Digital/DTS streams are always shown on the front
panel display as Dolby Digital (x/x).x or DTS (x/x).x, where the
bracketed numbers indicate the active channels in the source material.
Active output channels are shown by the icons on the right hand side
of the front panel display. Possible incoming DD/DTS types are:
(1/0) - Mono, Centre channel only
(2/0) - Left/Right stereo
(2/0).1 - Left/Right stereo and LFE (Sub)
(2/2) - Left/Right stereo and Left/Right surround
(3/0) - Left, Centre, Right
(3/0).1 - Left, Centre, Right and LFE (Sub)
(3/2).1 - 5.1: Left, Right, Centre, Left Surround, Right Surround and
LFE (Sub)
(3/4).1 - 7.1: Left, Right, Centre, Left Surround, Right Surround,
Surround Back Left, Surround Back Right and LFE (Sub)
