Treble control
For the playback channel, treble can be regulated in three audio modes: minimum, flat and maximum mode. In flat mode
the audio is not influenced. In minimum and maximum mode, the treble range is from 0 to 6 dB in steps of 2 dB.
The programmable treble filter is implemented digitally and has a fixed corner frequency of 3000 Hz for the minimum
mode and 1500 Hz for the maximum mode. Because of the exceptional amount of programmable gain, treble should be
used with adequate prior attenuation, using volume control.

Bass control
For the playback channel, bass can be regulated in three audio modes: minimum, flat and maximum mode. In flat mode
the audio is not influenced. In minimum mode the bass range is from 0 to approximately 14 dB in steps of 1.5 dB.
In maximum mode, the bass range is from 0 to approximately 24 dB in steps of 2 dB. The programmable bass filters are
implemented digitally and have a fixed corner frequency of 100 Hz for the minimum mode and 75 Hz for the maximum
mode. Because of the exceptional amount of programmable gain, bass should be used with adequate prior attenuation,
using volume control.
