Changing treble, bass, or phase

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 frequency adjustment, to ensure a correct surround effect.
To change the treble
• Press < or > until the display shows the current treble setting.
For example:
• 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 more or less bright. 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:
• Press A or V to change the bass.
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.
To change the absolute phase
• Press > or < until the display shows the current phase.
For example:
• Press A or V to change the phase.
