Each source has a set of DSP presets associated with it, one for
each of the alternative audio formats: two-channel (PCM), Dolby
Digital, DTS, MPEG, and MLP.
When you choose a source an appropriate DSP preset is
selected for the incoming audio format.
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 Ambisonic.
You can also change the default DSP preset associated with the
source; see Changing the DSP preset for a source, page 33.

To change the DSP preset

●Press Preset (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.
