Matrix section

The M3000A provides eight matrices which allow output signals from the MIX buses 1–16
or the ST bus, or input signals from MATRIX SUB IN to be mixed at the desired level.
Matrix 1–8 are output in mono from MATRIX OUT jacks 1-8 respectively (page 27), and
can be used as foldback or for an individual monitor system.

A M1–M16 controls
When the TO MATRIX switch of the mix section is
on, these controls adjust the level of the signal which
is input from the corresponding MIX OUT to the
matrix. The " " position is nominal level (0 dB).
B STEREO A L/R controls
When the TO MATRIX switch of the STEREO A sec-
tion is on, these controls adjust the level of the signal
which is input to the matrix from ST OUT A. The " "
position is nominal level (0 dB).
C SUB IN L/R controls
These controls adjust the level of the signal which is
input to the matrix from the rear panel MATRIX SUB
IN jacks (page 27). The " " position is nominal level
(0 dB).
D ON switch
When this switch is turned off, the indicator will go
dark, and no signal will be output from the MATRIX
OUT jacks. However even in this case, the signal
sourced before passing through the LEVEL control
can be monitored from the MONITOR OUT jacks or
the PHONES jack by turning on the AFL switch (6).
E LEVEL control
This adjusts the final output level of the correspond-
ing matrix 1–8. The " " position is nominal level (0
dB).

F AFL switch
This switch allows the output signal of the corre-
sponding matrix 1–8 to be monitored from the
MONITOR OUT jacks or the PHONES jack. When
this switch is on (
signal before passing through the level control will be
sent to the MAS PFL bus, and the signal after passing
through the LEVEL control will be sent to the MAS
AFL bus, allowing you to monitor them from the
MONITOR OUT jacks or the PHONES jack.
When the monitor section MASTER PFL switch
(page 19) is off, you can monitor the signal of the
MAS AFL bus. When the MASTER PFL switch is on,
you can monitor the signal of the MAS PFL bus. How-
ever if even one of the input channel PFL switches is
on, the PFL bus will be given priority for monitoring,
meaning that it will not be possible to monitor the
matrix.
