5.1.3. Channel Fader Gain - Step Up/ Step Down
Set the input and output channel gain positions by the number of steps.
Positions can be varied from the current status by the designated number of steps.
One position varies per step.
9000M2 series Amplifier informs position values changed by commands.
Position values are shown in POSITION V/S GAIN TABLE.
Values are 1dB step under -40dB, and 2dB step under -60dB.
The 9000M2 series Amplifier informs position values changed by Step Up or Down.
