Multiple DAC curves
You can activate multiple DAC curves and, at the same
time, define the offsets between the multiple curves and
the recording curve.
The offset 0.0 dB only represents the recording curve.
Every setting varying from 0 produces four other curves
with the corresponding dB offset between them.
For better distinction, the recording curve is shown in
bold with multiple DAC curves.
You can use fixed offsets for all curves. In this case, the
adjustment range is 0 … 12 dB in steps of 0.5 dB.
