mixing is done before the sound processing: input signals are automatically scaled by
6 dB in order to prevent clipping during adding; after the addition, the 6 dB scaling is
compensated

ADC volume control left.
An 8-bit value to program the gain of the decimator for left
and right independently. The ranges are +24 to
63.5 dB and
∞
dB in steps of
0.5 dB. The default setting is 0 dB (value 00000000), see Table 53.
