size M:N i1 i2 i3... iN Audio matrix
mtx 0 (size 14:13) controls the
audio matrix; outputs 0-7 are
embedded sound; outputs 8-11 are
AES output 1 to 4; output 12 is
datalink;
inputs 0-3 are AES inputs,
inputs 4-11 are deembedded
sound; 12=1kHz sine, 13=
mute/silence
Note: Any combination of the three
basic commands are allowed, for
instance the following command to
set up a 10x10 audio matrix in a
single line:

mtx 3 (size 24:1) controls the
default scaling. The 12 fixed
scalings are 0-11, the 12 user
scalings are 12-23.

size M:N i1 i2 i3... iN GPIs mapped to scalings
mtx 4 (size 25:16) controls how
the 4-bit GPI values are mapped to
the 24 available scalings. The 12
fixed scalings are 0-11, the 12 user
scalings are 12-23. The 25

option
is to not perform any action at all.

Current scaling
mtx 5 (size 37:1) has no control, it
is only used to report the current
scaling back to the system
contoller. The 12 fixed scalings are
0-11, the 12 user scalings are 12-
23. 24-34 represent scalings 1-11
when they are selected by the auto
logic, 35 and 36 represent scaling
0 (no conversion) for output
environments 16:9 and 4:3
