M2500—Owner’s Manual
Features of the system
• The M2500-24 {32/40C/48C/56C} provides 24
{32/40/48/56} monaural input modules and
four stereo input modules. It also provides 14
AUX outputs, eight group outputs, stereo out-
put, and monaural output, for a generous total
of 25 output buses. The M2500 is ideal for a
wide range of applications from use as a main
PA mixer to use in installed systems.
• Eight independent matrix outputs are provided.
The GRP/AUX, STEREO, and MONO/C chan-
nel output signals and the input signals from
dedicated inputs can be mixed freely, and output
from the eight MATRIX OUT jacks. This is con-
venient for foldback, or for creating individual
mixes for monitor speakers or amps.
• Monaural input channels and GRP/AUX output
channels allow you to select not only conven-
tional LR (stereo) output or monaural output,
but also LCR (stereo+center) output. When LCR
output is selected, the level of the center output
signal is also controlled by the PAN control, for
accurate spatial positioning when a three-chan-
nel stereo+center playback system is used.
• Monaural input channels provide a 26 dB pad,
high pass filter switch, phase switch, four-band
EQ, and 100 mm full-stroke faders. +48 V phan-
tom power that can be switched on/off individu-
ally for each channel is also provided.
• An INSERT I/O jack is provided on each mon-
aural input channel as well as on the AUX 1–6,
GRP/AUX, STEREO, and MONO/C output
channels. This allows you to insert external
effect units as necessary.
• The GROUP/AUX FLIP switch allows the eight
100 mm fader output channels to be used either
for the GROUP or AUX buses. When used for
the AUX buses, all 14 AUX buses can be con-
trolled by 100 mm faders, which is convenient
when using the M2500 as a stage monitor con-
sole.
• The Scene Memory function allows you to store
the on/off status of each mono/stereo input
channel and GRP/AUX 1–8, STEREO, and
MONO/C output channels as one of 128 scenes.
Scenes can be recalled at any time from the front
panel or via MIDI. In addition, control change
messages can be used to individually switch
these channels on/off from an external device.
• Eight DIRECT RECALL switches are provided
to allow scene memories 1–8 to be recalled at the
touch of a single button. This allows multiple
channels to be switched on/off quickly.
• By changing a setting, the DIRECT RECALL
switches can be used as mute group switches.
Mute group switch settings allow the DIRECT
RECALL switches to individually add/remove
eight sets of mute settings.
• PFL switches are provided on all input channels,
and AFL switches are provided on all master
outputs. In addition, a MASTER PFL switch
allows the master output monitor signal to be
switched between pre/post fader. You can rap-
idly check the input/output signal sources at a
variety of points.
• The talkback signal and the test tone oscillator
(PINK/10 kHz/1 kHz/100 Hz) can be sent to any
of the AUX 1-2, 2-6, 7-10, 11-14, STEREO, or
MONO/C buses.
