Precautions
1. Avoid excessive heat, humidity, dust and
vibration
Keep the unit away from locations where it is
likely to be exposed to high temperatures or
humidity — such as near radiators, stoves, etc.
Also avoid locations which are subject to exces-
sive dust accumulation or vibration which could
cause mechanical damage.
2. Ventilation
The unit has ventilation slots on the top, rear and
bottom panels. Do not block these vents.
3. Avoid physical shocks, liquid and small
metal objects
Strong physical shocks to the unit can cause dam-
age. Handle it with care.
Do not place a container with liquid or small
metal objects on top of this unit. Liquid or metal
objects inside this unit are a fire and electrical
shock hazard.
4. Do not open the case or attempt repairs
or modifications yourself
This product contains no user-serviceable parts.
Refer all maintenance to qualified Yamaha service
personnel. Opening the case and/or tampering
with the internal circuitry voids the warranty.
5. Always power off before making connec-
tions
Always turn the power OFF before connecting or
disconnecting cables. This is important to pre-
vent damage to the unit itself as well as other con-
nected equipment.
6. Handle cables carefully
Always plug and unplug cables — including the
AC power cord — by gripping the connector, not
the cord.
7. Clean with a soft dry cloth
Never use solvents such as benzine or thinner to
clean the unit. Wipe clean with a soft, dry cloth.
8. Always use the correct power supply
Make sure that the power supply voltage specified
on the rear panel matches your local AC mains
supply. Also make sure that the AC mains supply
can deliver more than enough current to handle
all equipment used in your system.

MC32/12, MC24/12—Owner’s Manual
Introduction
Thank you for choosing the Yamaha MC32/12 or MC24/12 mixing console. Please read
this manual thoroughly to take best advantage of the console and extend its useful life.
Notes:
This manual has been written on the assumption that you already understand the basic
operation and technical terminology of mixing consoles.
Descriptions of MC24/12 specifications appear in brackets ({}) if they differ from the
MC32/12.
Features
• The MC32/12 provides 28 monaural and 2 stereo
input modules {the MC24/12 provides 20 mon-
aural and 2 stereo input modules}. The output
channels comprise stereo outputs, 10 mix out-
puts, and two matrix outputs, and support a wide
range of applications, from SR (sound reinforce-
ment) to facility acoustics.
• Each monaural input channel offers a 26 dB pad,
HPF, phase switch, 4-band EQ (HI-MID and LO-
MID frequencies are variable), and a 100 mm-
long full-stroke fader. Also, phantom power can
be turned on and off for every group of four
inputs.
• Four stereo AUX returns and TAPE IN jacks are
provided as standard.
• The master section of the console is located in the
center area of the unit, facilitating operation.
• The master section provides output channels for
MIX buses 1–10, with EQs and 100 mm-long
faders.
• Each input channel and four stereo AUX returns
include a PFL switch, and stereo bus, MIX buses
1–10, and Matrix 1–2 has an AFL switch,
enabling you to monitor the input/output
sources quickly.
• Using the GA Diversity function enables you to
set MIX buses 1–4 to Variable mode or Fix mode
individually. In Variable mode, you can change
the level of the signals sent out from the input
channels. This routing can be used as a conven-
tional AUX bus. In Fix mode, the level of the sig-
nals sent out from the input channels is fixed.
This routing can be used as a conventional group
bus. In this way, you can configure the bus for a
specific purpose.
• The console has two independent matrixes. You
can mix MIX buses 1–4 and the stereo bus indi-
vidually at the levels you desire and output them
from the MATRIX OUT 1–2 jacks. This routing
can be used as a mix for the foldback or for indi-
vidual speakers and amplifiers.
• The INSERT I/O jacks are provided for all mon-
aural input channels, the stereo bus, and MIX
buses 1–4. You can insert an external effect pro-
cessor, if necessary.
• Talkback signals can be sent to any of MIX buses
1–4, MIX buses 5–10, and the stereo bus.
• C-R monitor output enables you to select PFL/
AFL or TAPE IN as a monitoring source.
• The console’s sturdy finish and rugged design
assure its durability even under severe conditions
and rough on-site usage.

use the MIX bus 1–4 signals as group bus signals or AUX bus signals. This section of the console
allows you to select whether you wish to use MIX buses 1–4 as group buses or AUX buses.
A M1–M4 switches
These switches are used to select whether the level of signals sent from the input channels to
MIX buses 1–4 will be fixed (FIX) or variable (VARIABLE).
■ When FIX is on:
The selected MIX bus(es) function as a group bus. The
level of the signal from each input channel will be fixed,
and the M1–M4 mix level controls of the input channels
that correspond to the MIX buses will be disabled.
■ When FIX is off:
The selected MIX bus(es) function as an AUX bus. Signals
that pass through the M1–M4 mix level controls of each
input channel (see page 2, monaural input channel
8, and
page 4, stereo input channel
6) are sent to the
corresponding MIX buses.
Mix section
This section consists of the output channels that handle MIX bus 1–10 signals individually.
Signals that pass these output channels are output from MIX OUT 1–10 jacks (see page 17, rear

The MC32/12 and MC24/12 provide four stereo AUX returns. Use the paired AUX RETURN
1–4 L/R jacks (see page 17, rear panel
8) to input stereo signals. Alternatively, connect signals
only to the AUX RETURN 1–4’s L jack to use the routing as a monaural AUX return.
A M1–M4 mix level controls
These controls are used to route signals input
from the AUX RETURN 1–2 jacks to MIX buses
1–4. The L channel of a stereo input signal is
sent to MIX buses 1 and 3, and the R channel
signal is sent to MIX buses 2 and 4. For a
monaural signal input, the same signal is sent to
MIX buses 1–4.
B M5–M10 mix level controls
These controls route the input channel signals
at the AUX RETURN 3–4 jacks to MIX buses
5–10. The L channel of a stereo input signal is
sent to MIX buses 5, 7, and 9, and the R channel
signal is sent to MIX buses 6, 8, and 10.
C ST (Stereo) level control
This control knob enables you to adjust the level of signals sent from the AUX RETURN 1–4
jacks to the ST bus, and does not affect the M1–M10 mix level control settings (
1 and 2).
D ON switch
This switch is used to turn on and off the corresponding AUX return. When you turn this
switch off, no signals are sent to the ST bus and MIX buses 1–10. However, using the PFL switch
5 enables you to monitor the signals via the C-R MONITOR OUT jacks or PHONES jack.
E PFL switch
When you turn this switch on, the AUX return signals will be routed to the PFL bus, and you
can monitor the signals via the C-R MONITOR OUT jacks or PHONES jack. The signals are
not affected by the M1–M10 mix level controls (
1 and 2), ST level control (3), or ON
switch (
4).
Note: The M1–M4 switch settings in the Variable/Fix select section do not affect the M1–
M10 mix level control settings. If the switches are set to FIX, signals that pass the M1–M10
mix level controls will still be sent to MIX buses 1–10.
