Matrix Assignment
Set the matrix assignment (matrix crosspoint) to ON or OFF.
The DP-SP3 transmits changed value data after receiving this command.
94H, 03H, , ,
00H - 01H (Input channel 1 - 2)
00H - 05H (Output channel 1 - 6)
00H: to assign OFF
01H: to assign ON
Example of setting the matrix assignment from Input channel 1 to Output channel 1 to ON:
94H, 03H, 00H, 00H, 01H
Matrix Crosspoint Gain
Set the crosspoint gains by position.
The DP-SP3 transmits changed value data after receiving this command.
95H, 03H, , ,
00H - 01H (Input channel 1 - 2)
00H - 05H (Output channel 1 - 6)
00～3DH : Gain Position (-INF - 0dB), refer to Value vs. Gain Table for Crosspoint gain.
60～6FH : Position Down (1～16 Step Down)
70～7FH : Position Up (1～16 Step Up)
Example of setting the crosspoint gain from Input channel 1 to Output channel 1 to 0dB:
95H, 03H, 00H, 00H, 3DH
Example showing 3-step Up of Input channel 1 to Output channel 1 crosspoint gain
95H, 03H, 00H, 00H, 72H
