Features of the system
The M3000A provides a generous number of input
modules; 4 stereo and monaural (the M3000A-56C
provides 56 monaural, the M3000A-40C provides 40
monaural, the M3000A-32 provides 32 monaural, and
the M3000A-24 provides 24 monaural). Stereo out-
put, 16 mix outputs, and 8 matrix outputs are pro-
vided in addition. The M3000A is suitable for use in a
wide range of applications, such as the main mixer for
sound reinforcement, as a monitor mixer, or in build-
ing installations.
The GA Diversity function allows each pair of MIX
buses 1/2–7/8 to be switched between group bus
(fixed output level from the input channels) and AUX
bus (variable output level from the input channels).
Bus configuration can be set up as needed.
The Scene Memory function allows the on/off status
of the mono/stereo input channels, MIX OUT 1–16,
and STEREO A OUT to be saved as one of 128
“scenes.” Scenes can be selected from the front panel,
or by MIDI program change messages from an exter-
nal device. In addition, MIDI control change mes-
sages transmitted from an external device can be used
to switch the individual on/off status of input chan-
nels or bus outputs channels.
By modifying internal settings, Scene Memory num-
bers 1–8 can be used as mute groups. In this case, up
to eight mute (on/off) settings can be added/defeated
individually.
Eight VCA master faders allow the gain of multiple
input channels to be controlled as a group. By group-
ing the desired input channels and assigning them to a
VCA master fader, you can adjust the mix as appropri-
ate for the on-state action using the VCA master fad-
ers alone.
The mono input channels provide a 26 dB pad, HPF,
phase switch, four-band parametric EQ, and 100 mm
full stroke faders as well as DIRECT OUT jacks. Phan-
tom power is also provided, and can be switched on/
off individually.
The M3000A-40C/M3000A-56C features a center
master design that places the master section in the
middle of the mixer for superior operability.
All input channels provide a PFL switch, and an AFL
switch is provided for MATRIX OUT 1–8/MIX OUT
1–16/STEREO A OUT/STEREO B OUT. This makes it
easy to check your input/output sources.
Eight independent matrices are provided. The signals
from MIX OUT 1–16/STEREO A OUT and dedicated
input jacks can be mixed at the desired levels, and out-
put from MATRIX OUT jacks 1–8. This capability can
be used for foldback or as a mix for individual speak-
ers/amps.
All mono input channels, stereo buses, and MIX buses
provide an INSERT I/O jack. External effect proces-
sors can be inserted as necessary.
The talkback signal and test tone oscillators can be
sent to any of the MIX buses 1-2–13/16 or the stereo
buses.
As monitor sources for the monitor output, you can
select (in addition to STEREO A OUT), PFL from the
input channels, AFL/PFL from MATRIX OUT 1–8/
MIX OUT 1–16/STEREO A OUT/STEREO B OUT, or
2TR IN 1/2.
