Analog Input Advisory Volume (Address 1Eh)
Digital Input Advisory Volume (Address 1Fh)
Defines the maximum analog input volume level used by the class H controller to determine the appropri-
ate supply for the HP and Line amplifiers.
Defines the maximum digital input volume level used by the class H controller to determine the appropri-
ate supply for the HP and Line amplifiers.
Note:
the highest required advisory volume. When any respective amplifier is powered down, the charge pump’s
voltage automatically adjusts to the appropriate level.
