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 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 digrams 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.
