Matrix Section - Yamaha M3000-24 Owner's Manual

Control panel

Matrix section

The M3000 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
This is an on/off switch for the output of the matrix.
When this is turned off, no signal will be transmitted
from the corresponding MATRIX OUT jack or to the
MAS AFL bus. However even in this case, if the AFL
switch (6) is turned on, the signal before passing
through the LEVEL control can be monitored from
the MONITOR OUT jacks or the PHONES jack.
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 (
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.
