.
The owner of an input has access to the Gain Compensation
Recalibrate
button. Pressing and
holding the
Recalibrate
will reset the
Gamma point
.
When the preamp is in
Line
mode, pressing and holding
Recalibrate
will move the
Gamma point
to the current position of the analogue gain knob. This means that the analogue gain value now
equals a digital trim value of 0dB and no digital trim is applied.
When the preamp is in
Mic
mode, pressing and holding
Recalibrate
will move the
Gamma point
to
10dB below
the current position of the analogue gain knob. This feature has been designed to
protect the compensated signal against digital clipping, in the event that the analogue gain control is
drastically reduced. This means that the initial digital trim value is -10dB, as the analogue gain value
is 10dB above the Gamma point.
Pressing the + or - 3dB buttons raises or lowers the Gamma point by 3dB.
