Using the 861
Reference Digital
Surround Controller
Changing the DSP preset
Each source has a set of DSP presets associated with
it, one for each of the alternative content types: Music
2 (2-channel music), Music 6 (multichannel music),
Movie 2 (2-channel movie soundtrack), or Movie 6
(multichannel movie soundtrack).
When you choose a source, a DSP preset is selected
depending on the incoming content type.
For example, if you have selected the CD source and
are playing a conventional CD, the Trifield DSP preset
will initially be selected.
You may then wish to choose a different DSP preset,
such as Music or Ambisonics.
You can also change the default DSP preset assigned
to the source; see
To assign a DSP preset to a source
,
page 24.
The sequence of DSP presets for each content type is
as follows:
Content type Presets available
Music 2, Movie 2 Music, Trifield, Ambisonics, Super
Stereo, Music Logic, PLIIx Music,
Stereo, Direct, PLIIx Movie, PLIIx
THX, TV Logic, Mono.
Music 6 Discrete, PLIIx Mus6, THX Music,
Ambisonics B format.
Movie 6 Cinema, PLIIx Mov6, THX, THX
Surround EX, THX Ultra2 Cinema.
In each case these will be followed by any user-defined
presets you have stored for the appropriate content
type.
To change the DSP preset
Press DSP (front panel or remote) to step between
the different DSP presets.
You will be able to choose any of the predefined DSP
presets, or any user-defined presets you have stored.
The 861 Reference Digital Surround Controller
mutes the sound while you change DSP preset, to
avoid clicks in the speakers.
