Control Command and Setting Value
Channel Fader Gain (Position)
Set the input and output channel fader gains by position.
For the relationship of position to gain (dB), refer to the Position vs. Gain Table for Fader.
The D-901 transmits changed value data after receiving this command.
91H, 03H, <Channel Attribute>, <Channel Number>, <Position>
<Channel Attribute>
00H: Input channel
01H: Output channel
<Channel Number>
When Channel Attribute=00H: 00H - 0BH, 7FH (Input channel 1 – 12, All input channels)
When Channel Attribute=01H: 00H - 07H, 7FH (Output channel 1 – 8, All output channels)
<Position>
00H - 3FH
(-
∞
- +10dB, see the Position vs. Gain Table)
Example of setting Input Channel 1 fader gain to 0 dB:
91H, 03H, 00H, 00H, 2AH
Channel Fader Gain (Step)
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.
The D-901 informs position values changed by step Up or Down.
91H, 03H, <Channel Attribute>, <Channel Number>, <Step>
<Channel Attribute>
00H: Input channel
01H: Output channel
<Channel Number>
When Channel Attribute=00H: 00H - 0BH, 7FH (Input channel 1 – 12, All input channels)
When Channel Attribute=01H: 00H - 07H, 7FH (Output channel 1 – 8, All output channels)
<Step>
UP: 41H - 5FH (1 step up - 31-step up) ; Example showing 1step Up: 41H
Down: 61H - 7FH (1 step down – 31–step down) ; Example showing 1step Down: 61H)
Example showing 3-step Up of Input Channel 1 fader gain
