Auto gain: If this function is turned off, then the total level before the output will be
increased up to 3dB, depending on clipping controller settings. This is limited via the
weaker saturation threshold (the maximum of which would normally be achieved before full
overdrive), but in this case the value is raised to guarantee maximum headroom. Without
auto gain, a volume increase will occur with absolute levels that remain static due to the
altered overtone spectrum.
If 'auto gain' is activated, then such a level increase will be avoided and a constant
loudness will be aimed for independent of the saturation curve. For this, the input of the
clipper will be reduced to that of the expected level gain at the output, so that the 'same
ratio' governs again. This measure can be especially necessary with the employment of the
dual-band clipper, since under some circumstances a double saturation of the signal can
sound 'overdriven' without dampening.
Consequently, the 'Auto gain' function itself ensures a certain amount of airiness with
additionally generated overtones.
