[GainSelector]. [DigitalAll] (master gain), [DigitalRed]* (digital R gain), and
[DigitalBlue]* (digital B gain) can be configured.
❷ Configure the gain value in [Gain].
• [DigitalAll] (master gain) can be set to a value from x1 to x16 the analog
gain value. The resolution is set in about 0.1dB steps. Values are
configured by multipliers.
• The [DigitalRed]* (digital R gain) and [DigitalBlue]* (digital B gain) can be
set to a value from x0.447 to the [ADigitalAll] (master gain) value.
The resolution is set in 0.000122 steps. Values are configured by multipliers.
