chain for ALP882e and ALP882e-MIC
The mixer inputs and outputs are numbered 0 to 31. The mixer offers 32 mix buses, with 32 input
channels per bus, and a digital gain associated to each channel in a mix.
The DAW0 to DAW15 inputs are the 16 audio channels coming from the host machine
●
(played by software on the host machine).
The ANA0 to ANA7 inputs are the eight analog input channels (IN1 and IN8).
●
The inputs AES0 to AES7 are the eight input channels of the four digital inputs AES/EBU IN1
●
to AES/EBU IN4.
The DAW0 to DAW15 outputs are the 16 audio channels destined for the host machine
●
(captured by software on the host machine).
The ANA0 to ANA7 outputs are the eight analog output channels (OUT1 and OUT8)
●
The AES0 to AES7 outputs are the eight channels of the four stereo digital outputs AES/EBU
●
OUT1 to AES/EBU OUT4.
By default, the matrix gains are positioned so as to have:
DAW0 PLAY -> ANA0 OUT 1
DAW1 PLAY -> ANA0 OUT 2
DAW2 PLAY -> ANA0 OUT 3
DAW3 PLAY -> ANA0 OUT 4
DAW4 PLAY -> ANA0 OUT 5
DAW5 PLAY -> ANA0 OUT 6
DAW6 PLAY -> ANA0 OUT 7
DAW7 PLAY -> ANA0 OUT 8
DAW8 PLAY -> AES0 OUT (AES/EBU OUT1 Left)
DAW9 PLAY -> AES1 OUT (AES/EBU OUT1 Right)
DAW10 PLAY -> AES2 OUT (AES/EBU OUT2 Left)
DAW11 PLAY -> AES3 OUT (AES/EBU OUT2 Right)
DAW12 PLAY -> AES4 OUT (AES/EBU OUT3 Left)
