MIXING
CONSOLES
-24/-32/-40C/-48C/-56C
When discerning sound-reinforcement professionals think “console”
they also think “Yamaha.” And with good reason. Yamaha soundreinforcement consoles have, for many years, been standards by
which others are judged. Yamaha’s new M2500 consoles up the ante
once more, defining new levels of performance, control, versatility,
and reliability for an industry that never stands still. Innovate features such as the group/aux flip function and LCR panning offer
unprecedented control, while no-compromise circuit design, layout,
and component selection from the critical head amplifiers right
through to the output connectors ensure that you get the cleanest,
most accurate signal possible. The most important and in-demand
features have all been implemented as well: 4-band EQ with two
sweepable mid-bands on all mono inputs, a matrix submix of the
group, auxiliary, stereo and mono/center busses as well as the sub
inputs, 128-scene memory, 100-millimeter faders, and more.
■ A wide range of input configurations for all applications: 24, 32, 40, 48, or 56 mono inputs
with 4 stereo inputs.
■ A total of 25 output busses: 8 group, 14 auxiliary, 1 stereo, and 1 mono/center buss.
■ Full-length 100-mm faders for all group masters and aux sends 1 through 6 — the group master
faders/controls and aux send 7 through 14 controls can be flipped for maximum system versatility.
■ Group/auxiliary flip function allows the master section to be instantly optimized for main or
monitor mixing.
■ Mono channel pan controls switchable for LR or LCR operation.
■ All mono inputs feature switchable phantom power, 26-dB pad switches, 44-dB gain trim,
high-pass filter switches, and versatile 4-band EQ.
■ 128 mute scenes recallable via numeric keys, 8 direct recall switches, or MIDI control for mute
automation.
■ The 8 direct recall switches can alternatively be used as mute group switches.
■ 13 x 8 submix matrix mixes the group/aux, stereo, and mono busses, as well as the L and R sub
input signals, to 8 discrete outputs.
■ Odd/even group assign as well as stereo and mono buss assign switches on all input channels.
■ Aux sends 3 through 14 switchable for pre- or post-fader operation.
■ All outputs are balanced: stereo, mono/center, group, aux, monitor, and matrix out.
■ Insert patch points on all mono channels as well as the stereo, mono/center, group, and aux busses.
■ 11 large illuminated VU meters for precise visual level monitoring.
■ 3-point input level indicators on all input channels.
■ High-capacity, high-performance external power supply with full power monitoring (two can be
connected for automatic switchover in case of failure).

All of the mono inputs and group master controls feature LCR
switches which, when engaged, assign the related panpot to the left,
right, and center busses for LCR panning rather than just to the left
and right busses as for standard LR stereo panning. When an LCR
switches is not engaged, the corresponding PAN control functions in
the normal way, panning the signal from left to right on the stereo
buss. When a channel’s LCR switch is engaged, however, the center
panpot position directly feeds the channel signal to the MONO/C
buss, which can feed a center amp/speaker system as required,
while intermediate pan positions feed both the L or R and C buss
proportionately. The advantage is that centered signals are heard
precisely in the center of the sound field, regardless of listening
position — an ideal situation for vocals, speech, etc.

Signal Level
This innovative feature makes it possible to flip the functions of
the group master 1 through 8 controls (including pan pots, assign
switches, and insert I/O jacks) with aux send controls 7 through 14
via a single switch. When the GROUP/AUX FLIP switch is set to
GROUP, the 100-mm group master faders and related controls
function in the normal way, affecting the signal fed to the console’s
group outputs — the ideal configuration for most house mixing
applications. When the GROUP/AUX FLIP switch is set to AUX,
however, the group master
faders are flipped with rotary aux
sends 7 through 14, so that all of
the console’s master aux sends
are controlled via full-length
faders for unmatched monitor
mixing convenience.

STEREO INPUTS
MONO INPUTS
INPUT CHANNELS
■ Inputs
■ 14 Aux Sends
The mono input channels feature balanced
XLR-type microphone/line inputs. +48V
Phantom power is independently switchable
for all mono inputs, providing direct compatibility with high-performance phantompowered condenser microphones and DI
boxes.
Stereo line sources can be directly connected to any of the 4 stereo input channels
(a total of eight inputs). Stereo channel 1 has
switchable “A” or “B” inputs: the “A” inputs are
balanced XLR type connectors, and the “B”
inputs are standard RCA pin jacks type for
compatibility with the widest possible range of
line sources. Stereo channels 2 through 4
have balanced TRS inputs.
The AUX 1 through AUX14 controls are
mono auxiliary sends, feeding the corresponding auxiliary busses. The AUX 7 through AUX
14 signals can be re-routed to the group
master controls, as described in the “MASTER
CONTROLS” section, below. AUX 1 and AUX 2
are hard-wired pre-fader, while the remaining
12 sends can be switched to receive the preor post-fader signal in groups of four.
■ Channel Insertion
Insert send/return patch points are
included on all mono channels for convenient
insertion of compressor/limiters (a must for
top-quality vocal sound), equalizers, or any
other outboard equipment you might need to
apply to individual channels.
■ Input Controls & Level Matching
Gain trim controls with a 44-dB range on
all mono inputs, independent 40-dB gain
controls for the A input on stereo channel 1
and stereo channels 2 through 4, and 30-dB
gain controls for the B input on stereo channel
1, facilitate optimum level matching with a
wide range of sources. The mono inputs
additionally feature 26-dB pad switches and
phase switches for easy input phase correction.
■ Filters & Flexible 4-band Channel
EQ
All mono channels feature a switchable
high-pass filters to effectively eliminate rumble
and other low-frequency noise. The mono
channels also feature a very flexible 4-band
equalizer which provides sweepable frequencies for the HI MID and LO MID bands. The
stereo channels offer 2-band shelving EQ. EQ
bypass switches are provided on all channels
so equalization can be punched in or out as
required without having to change settings.
■ Buss Assign & Pan/Balance
Controls
All mono and stereo channels have odd/
even assign switches for the 8 group busses,
as well as stereo and mono buss assign
switches. The mono channels have PAN
controls switchable for LR or LCR operation,
and the stereo channels have balance
controls.
■ 3-point Level Indicators
All mono and stereo channels feature 3point input level indicators for accurate
monitoring of pre-fader signal levels. SIGNAL,
NOM (nominal), and PEAK LEDs provide a
broader “view” of channel signal levels than
the usual one- or two-LED indicators.
■ Channel Faders, Pre-fader Listen,
& Channel ON Switches
Smooth, noise-free 100-mm linear faders
make it easy to set up the optimum balance
between channels, while PFL (Pre-Fader
Listen) switches allow convenient solo
monitoring of the channel’s pre-fader signal.
All channels additionally feature ON/EDIT
switches and indicators that can be used to
switch the channel signal into or out of the
mix — allowing editing of mute scenes, for
example — without changing any other
settings.
MASTER CONTROLS
■ Master Auxiliary Sends
■ Sub Inputs
Master auxiliary sends 1 through 6 feature
full-length 100-millimeter faders with ON and
AFL switches, and theses directly feed the
corresponding AUX outputs. Master auxiliary
sends 7 through 14 are normally rotary
controls with ON and AFL switches, feeding the
corresponding AUX outputs, but these can be
flipped with the 100-millimeter faders and
related controls normally assigned to the 8
group busses.
Sub inputs to the stereo L and R busses, the
mono/center buss, and the submix matrix
allow external line-level signals to be added to
the mix as required.
■ Group Master Controls
All 8 group master faders are full-length
100-mm types with ON/EDIT switches and
indicators, AFL switches, PAN controls, MATRIX
assign, STEREO assign, MONO assign, and LCR
panning mode switches. These group controls,
in conjunction with the flippable aux master
controls, lets you configure the console to
meet your group/auxiliary requirements while
retaining full use of all 25 output busses.
■ Group/Aux Flip Switch
Flips the functions of the master group
controls (1 through 8) with aux send masters
7 through 14. This makes it possible to to
instantaneously optimize the master control
section for main or monitor mixing applications.
■ All Balance Outputs with Insert
Patching
All outputs from the M2500 console —
stereo, mono/center, group, aux, monitor, and
matrix out — are electronically balanced for full
compatibility with professional equipment and
optimum performance with long signal runs.
The group/aux, aux, stereo, and mono outputs
also feature insert patch points for external
signal processing.
■ 128 MIDI Scene Memory & 8 Mute
Groups
In the M2500 console the channel, group/
aux, stereo, and mono/center buss mute
functions are electronically controlled by a
microcomputer and MIDI interface. Up to 128
mute “scenes” can be stored in memory and
recalled either via the panel controls or an
external MIDI device. Eight DIRECT RECALL
switches can be used for instant recall of the
most often-used scenes, while others can be
recalled via the numeric keys. The memory
contents can be checked and edited at any
time without actually affecting the mix.
In addition to recalling complete scenes,
external MIDI control can be used to individually turn the applicable channels and busses
off or on as required. A MIDI sequencer or
computer, for example, could be used for
complete mute automation. And since the
M2500 also transmits MIDI program change
messages whenever a scene is recalled, it can
be linked to MIDI-controllable signal processors so that appropriate effects are recalled
automatically. Furthermore, scene data can be
dumped to a MIDI data recorder or other
storage device for long-term storage.
■ Submix Matrix
The matrix mix concept was a Yamaha
innovation which has virtually become an
industry standard in professional audio
consoles. The M2500 features a 13 x 8 matrix
mix which allows the 8 group/aux buss signals,
the stereo signals, the mono buss signal, and
the L and R sub input signals to be mixed to
eight balanced outputs for extra stage monitor
mixes, zoned speaker mixes, or just about any
type of mix the job requires. All eight matrix
mixes include mix on/off switches and AFL
switches.
■ Flexible Monitoring & Metering
In addition to balanced stereo monitor
outputs, the M2500 consoles feature a
balanced mono/center monitor output for an
extra margin of monitoring versatility. There’s
also a separate headphone output with its own
level control. A L+R switch sums the left- and
right-channel signals when you want to
monitor in mono via the stereo monitor
outputs.
A total of 11 large illuminated VU meters
with built-in peak-reading LEDs provide
accurate visual level monitoring. Eight of the
meters can be switched to display levels on
the group busses, aux busses, or the matrix
outputs. The remaining three meters show
levels on the stereo and mono/center busses.
■ Oscillator/Talkback Module
For talkback the M2500 features a panelmounted microphone jack with level control
and on/off switch. For convenient system
calibration and testing there’s even a built in
oscillator with 100Hzm 1kHz, 10kHz and pink
noise output.
■ Lamp Connectors
Connectors for up to three Yamaha LA1800
(option) console lamps are provided on the
rear panel.
