18 M2500—Owner’s Manual
Matrix section
The M2500 provides an eight channel matrix section
that allows the output signals from the G1/A7–G8/
A14 section, the output signals from the stereo/mon-
aural master section, and the input signals from the
SUB IN MATRIX jacks to be mixed at a desired level.
Matrix 1–8 are output individually from MATRIX
OUT jacks 1–8 (page 27), and can be used as mixes
for foldback or individual monitor systems.
A SUB IN L/R control
These adjust the signal levels that are input to the
matrix from the rear panel SUB IN MATRIX jacks
(page 28). The “▲” position is nominal level (0 dB).
B ST L/R controls
When the MATRIX switch of the STEREO section
(page 16) is on, these controls adjust the level of the
signal that is sent from the STEREO section to the
matrix. The “▲” position is nominal level.
C MONO/C control
When the MATRIX switch of the MONO/C section
(page 16) is on, this control adjusts the level of the
signal that is sent from the MONO/C section to the
matrix. The “▲” position is nominal level.
D G1/A7–G8/A14 controls
When the MATRIX switches of the G1/A7–G8/A14
section (page 11) are on, these controls adjust the
level of the signal that is sent from the corresponding
GRP/AUX OUT to the matrix. The “▲” position is
nominal level.
E LEVEL control
This adjusts the final output level of the matrix. The
“▲” position is nominal level.
F ON switch
This switches the output of the matrix on/off.
G AFL switch
Using this switch, the signal of the matrix can be
monitored from the MONITOR OUT/PHONES
jacks. If the PFL switches of all input channels are off,
turning this AFL switch on will allow you to monitor
the output signal of the corresponding matrix from
the MONITOR OUT/PHONES jacks. Use the MAS-
TER PFL switch of the monitor section to switch the
monitor signal between pre/post-fader (LEVEL con-
trol).
