Advanced setup
The first three adjustments affect Dolby Pro Logic II or IIx processing (or post-
processing) in Music mode only. Movie and Game modes where available
are preset as part of their specification to match the encoding or provide a
specific effect. These adjustments have no affect in these modes.

Panorama mode -
A Dolby Pro Logic II/IIx mode that extends the front Stereo
image to the surround sound speakers for a more enveloping experience.
This mode can be either On or Off.
Centre Width -
Allows gradual adjustment of the centre image from being
produced only by the Centre speaker (Setting 0) through levels of being
spread between the centre channel and Left and Right speakers to finally
being produced by the Front Left and Right speakers only (Phantom Centre,
Setting 7). Useful in optimising the Front/Centre/Right soundfield for best
integration of the 3 speakers. Best tuned by ear.
Dimension -
Adjusts the soundfield to be gradually shifted from the front
of the room to the back to suit taste, speaker positioning and size of room.
Setting 0 has the image furthest forward, 6 furthest back.
All three adjustments are a matter of personal preference, experiment for
the settings that you prefer when you are using Dolby Pro Logic II or Dolby
Pro Logic IIx decoding.
DTS-HD speaker re-map
As there is no "official" speaker layout for discrete 7.1 channel audio it could
be possible that the original master track of a 7.1 soundtrack was mastered
with a different speaker layout than the one being used in your home. DTS
have addressed this issue for DTS-HD Master Audio and High Resolution
Audio by including in the bitstream flags to tell the receiving AV Receiver which
of a 7 nominal 7.1 speaker layouts was actually used. By using special DTS
Speaker Remap algorithms the 551R V2 is able to electronically "reposition"
the speakers (i.e. direct the audio propagation), so that the playback matches
the original encoded layout for the best possible sound quality.
A second aim of this technology is that by re-purposing some of the 7.1
available channels it is possible to use some of them to do new things such
as adding a height element to the sound field.
The following diagrams show the 7 possible encoding schemes for reference.
The angles quoted refer to the angle from a nominal 0 degrees line through
the centre channel to each speaker either side right or left of that line.
Configurations 1 and 5 are variants of normal 7.1 setups whilst Configuration
6 can increase the available panning of the front channels.
Configurations 2,3,4 and 7 are less conventional and re-purpose some of
the available 7.1 channels to provide an extra height dimension to the sound
field in different ways. Please refer to the DTS website for more details on
this new technology.
