MTRX - Matrix
This command selects/reports the matrix routing of an input to an output.
Command form: DEVICE
MTRX
<SRC CHNL> <SRC GRP> <DEST CHNL>
<DEST GRP> [Value]
Argument details
Name Description
Device 0–7 or * to select all units
MTRX Command form
SRC CHNL See Groups and Channels, page 93
SRC GRP I, M, P, L, E
DEST CHNL See Groups and Channels, page 93
DEST GRP O, P, E
Value 0 = Cross point off
1 = Cross point on (not valid for mic sources)
2 = Cross point toggle (not valid for mic sources)
3 = Non-gated (mic sources only)
4 = Gated (mic sources only)
Null = Current mode
Example:
#47 MTRX 1 M 4 O 4
On PSR1212 unit 7 (
#47
), mic (
M
) channel
1
is routed (
MTRX
) as gated (
4
) to output (
O
)
4
.
MTRXLVL - Matrix Attenuation Adjustment
This command selects/reports the matrix level at the cross point.
Command form: DEVICE
MTRXLVL
<SRC CHNL> <SRC GRP>
< DEST CHNL> <DEST GRP> [Value] [A/R]
Argument details
Name Description Units
Device 0–7 or * to select all units
MTRXLVL Command form
SRC CHNL See Groups and Channels, page 93
SRC GRP I, M, P, L, E
DEST CHNL See Groups and Channels, page 93
DEST GRP O, P, E
Value -99.99 to 99.99 dB
Null = Current mode
A/R A = Absolute
R = Relative, Null = Relative
Example:
#40 MTRXLVL 1 M 4 O -6
On PSR1212 unit 0 (
#40
), cross point
attenuation (
MTRXLVL
) at the point of mic (
M
)
1
and output (
O
)
4
is
-6
dB.
SRC = source
DEST = destination
CHNL = channel
GRP = group

Values indicate entry
range only. Actual
internal range of the gain
stage is from
-60 to 0 and absolute values will
be limited to the internal gain
range. Absolute levels below -60
will mute the gain stage.
