Defining your own presets

The digital surround controller provides sophisticated treble and
bass controls, to allow you to adjust the broad balance of the
system to correct for the acoustics of your listening room, or for
a misbalanced recording.
The controls are more subtle than conventional tone controls,
and take advantage of digital signal processing techniques to
provide a more natural adjustment of the frequency response.
You can also change the absolute phase of the signal, to
compensate for recordings which are out of phase.
In each case all the outputs of the digital surround controller are
given the same adjustment, to ensure a correct surround effect.
If you have a Meridian DSP loudspeaker these menus appear on
the speaker. For more information see the speaker user guide.
