Customising the digital surround processor
25
The digital surround processor 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 processor are
given the same frequency adjustment, to ensure a correct
surround effect.
If you have a Meridian DSP Loudspeaker these menus appear
on the speaker menus. For more information see the speaker
user guide.
To change the treble
● Press > or < until the display shows
the current treble; for example:
Treble +1.5
● Press A or V to change the treble.
The treble control tilts the frequency of the response over the
entire frequency range to make the sound brighter or dimmer. It
can be adjusted between ±10dB in 0.5dB steps. Normally
settings between +1.0 and -2.0 will give the most natural results.
To change the bass
● Press > or < until the display shows
the current bass setting; for example:
Bass +0.5
The bass control allows you to adjust the bass response in the
room by ±5dB in 0.5dB steps. Normally settings between +3.0
and -2.0 will give the most natural results.
● Press A or V to change the bass.
To change the absolute phase
● Press > or < until the display shows
the current phase; for example:
Phase +
● Press A or V to change the phase.
