Introduction
Thank you for your purchase of the YAMAHA MG32/14FX or MG24/14FX mixing console.
This console offers excellent cost-performance and is ideal for use as the main mixer in an
SR setup or as part of an installed system.
Please read through this Owner’s Manual carefully before beginning use, so that you will be
able to take full advantage of the mixer’s superlative features and enjoy trouble-free operation
for years to come. Be sure to retain this manual in a safe place.
● Provides 24 (MG32/14FX) or 16 (MG24/14FX) monaural input
channels suitable for connection to both microphones and
line-level devices. Also provides four line-level stereo inputs.
● Built-in dual digital effector, based on Yamaha’s acclaimed SPX
multi-effector technology, can apply a variety of internal effects
to both vocal and instrumental inputs.
● Convenient “tap delay” feature lets you set the internal effect’s
delay time by tapping on a button (or by stepping on a sepa-
rately-sold foot switch).
● Provides dual stereo outputs, two effect outputs, six AUX out-
puts, and four group outputs—for a total of 14 outputs. You can
use the AUX and GROUP outputs both to connect to external
devices (such as effectors and MTRs) and to create custom
mixes for targeted speakers or amps for stage monitoring.
● An independently controlled MONO output jack feeds out a mix
of the main ST output signal, ideal for connection to a subwoofer
or other SR system extension.
● All monaural channels are equipped with an INSERT I/O jack
for independent connection to an external effector.
● Includes independent PFL switches for each input channel, for
each AUX return, and for the 2TR IN bus, together with inde-
pendent AFL switches for each AUX and GROUP output and for
the main ST output. These switches make it easy to selectively
monitor the input and output signals through headphones con-
nected to the PHONES jack.
● Phantom power supply can provide DC +48 power to all XLR
input jacks, allowing you to connect phantom-powered con-
denser mics and direct boxes to any combination of monaural
channels. The phantom power can be independently switched on
and off in eight-channel blocks.
● Dual RETURN jacks can feed AUX return signals not only into
the ST bus but also into four of the AUX buses. These jacks can
also serve as an auxiliary stereo input.

■ MONAURAL CHANNELS Section
STEREO CHANNELS Section
1 PAD Switch
When this switch is on ( ), the mixer attenuates the input
signal by 26 dB.
2 GAIN Control
Adjusts the gain applied to the input signal level. To get the
best balance between the S/N ratio and the dynamic range,
adjust the gain so that the PEAK indicator (B) comes on just
as the signal approaches its maximum level.
On monaural channels: When the PAD switch (1) is off
( ), the GAIN control adjusts for input levels from –60 dBu
to –16 dBu. When the PAD switch is on ( ), the GAIN con-
trol adjusts for input levels from –34 dBu to +10 dBu.
On stereo channels: The GAIN control adjusts for input levels
from –34 dBu to +10 dBu.
3 Switch (High-Pass Filter)
This switch toggles the HPF on or off. To turn the HPF on,
press the switch in ( ). The HPF cuts frequencies below 80
Hz.
4 Equalizer Controls
• On monaural channels
A three-band equalizer adjusts the channel’s high, mid, and
low frequency bands. For each band, setting the knob to the
position produces a flat frequency response. Turning the
knob to the right boosts the corresponding frequency band,
while turning to the left cuts the band. The following table
shows the EQ type, base frequency, and maximum cut/boost
for each of the three bands.
• On stereo channels
A four-band equalizer adjusts the channel’s high, hi-mid,
lo-mid, and low frequency bands. For each band, setting the
knob to the position produces a flat frequency response.
Turning the knob to the right boosts the corresponding fre-
quency band, while turning to the left cuts the band. The fol-
lowing table shows the EQ type, base frequency, and
maximum cut/boost for each of the four bands.

5 AUX Controls (AUX1 to AUX6)
These knobs adjust the channel’s signal levels into AUX buses
1 to 6. Each knob controls the signal into the corresponding
AUX bus.
For AUX1 to AUX4, you use the PRE switch (6) to select
whether the pre-fader or post-fader signal is fed to the bus. For
AUX5 and AUX6, only the post-fader signal can be fed.
These knobs should generally be set close to the position.
On stereo channels, the L (odd) and R (even) input signals are
mixed before moving into the AUX bus.
To enable use of AUX5 and AUX6, you must turn on
the AUX5/AUX6 switch (
8).
6 PRE Switch
Selects whether the pre-fader or the post-fader signal is fed to
the corresponding pair of AUX buses. The upper PRE switch
controls the signal to AUX1 and AUX2; the lower switch con-
trols the signal to AUX3 and AUX4. If the switch is on ( ),
the mixer feeds the pre-fader signal to the corresponding buses.
If off ( ), the mixer feeds the post-fader signal.
There is no PRE switch for AUX5 and AUX6. For
these buses only the post-fader signal is available.
7 EFFECT Controls
These knobs adjust the channel’s signal levels into EFFECT
buses 1 and 2. Since the signal to the EFFECT buses is
post-fader, the level is always determined by the combination
of the EFFECT control and the channel fader.
On stereo channels, the L (odd) and R (even) input signals are
mixed before moving into the EFFECT bus.
These knobs operate as EFFECT controls only if
the AUX5/AUX6 switch is in off position ( ). If the
switch is on, these knobs adjust the output to the
AUX5 and AUX6 buses. (See
8 below.)
8 AUX5, AUX6 Switch
Selects whether the channel signal is sent to AUX buses 5 and
6 or EFFECT buses l and 2. If the switch is on ( ), the signal
goes to AUX5 and 6 buses; if off ( ), the signal goes to the
EFFECT buses. Note that the signal to these buses is always
post-fader.
9 PAN Control (Monaural Channels)
BAL Control (Stereo Channels)
The PAN control adjusts the signal’s pan positioning into the
Group 1-2 bus pair, into the Group 3-4 bus pair, and into the
Stereo bus’s L and R lines.
The BAL control knob sets the balance between left and right
channels. Signals into the L input (odd channel) feed to the
Group 1 and Group 3 buses and to the L line of the Stereo bus.
Signals into the R input (even channel) feed to the Group 2 and
Group 4 buses and to the R line of the Stereo bus.
If you are inputting to a stereo channel through the
L (MONO) jack only, the BAL knob operates as a
PAN knob.
0 ON Switch
Sets the channel on or off. To turn the channel on, press the
switch in ( ) so that it lights up orange. Be sure to turn on all
the channels that you wish to use. If you set the channel off
( ), you cut off all of its signal feed into the ST, GROUP,
AUX, and EFFECT buses.
• The ON switch does not affect the operation of
the PFL switch (A). You can monitor the chan-
nel’s pre-fader signal through the PHONES jack
even when the ON switch is set off.
•To reduce noise, turn all unused channels off
().
A PFL (Pre-Fader Listen) Switch
Use this switch to feed the channel’s pre-channel-fader signal
into the PFL bus, so that you can monitor the signal from the
PHONES jack. To turn PFL feed on, press the switch in ( )
so that it lights up.
• If you switch on output to both the PFL and AFL
buses, the mixer outputs only the PFL signal.
• If you set PFL on for multiple channels, the mixer
feeds the mixed signal from the channels into the
PFL bus.
B PEAK indicator
Lights up when the channel’s post-equalizer signal level comes
within 3 dB of the clipping level.
C SIGNAL indicator
Lights up when a signal is being input into the channel.
D GROUP Switches
Use these switches to feed the channel’s signal to the GROUP
1-2 and/or GROUP 3-4 buses. Setting the switch on ( )
causes the signal to feed into the corresponding GROUP buses.
These switches allow you to independently assign
the signal to groups regardless of the setting of the
ST switch (E).
E ST Switch
Set this switch on ( ) to feed the channel’s signal to the ST
bus.
F Channel Fader
Adjusts the output level of the channel’s signal. Use these fad-
ers to adjust the volume balance among the various channels.
To reduce noise, set the fader sliders for unused
channels all the way down.

G PHANTOM +48 V Switch
Toggles phantom power on or off to a set of eight adjacent
channels. The MG32/14FX has three of these switches: for
CHs 1 to 8, for CHs 9 to 16, and for CHs 17 to 24. The
MG24/14FX has two: for CHs 1 to 8 and for CHs 9 to16. If
using condenser microphones, set the switch on ( ) for all
channels to which these microphones are connected.
If this switch is on ( ), the mixer supplies DC
+48 V power to pins 2 and 3 of all XLR-type jacks in
the corresponding channels.
• Be sure to leave these switches off ( ) if you do
not need phantom power. Humming or damage
may result if you connect to an unbalanced device
or to an ungrounded transformer while this switch
is on ( ). But note that the switch may be left on
without problem when connecting to balanced
dynamic microphones.
• To avoid damage to speakers, be sure to turn off
amplifiers (or powered speakers) before turning
these switches on or off.

■ GROUP Section
This section adjusts the level and controls the flow of the signals
from the four GROUP buses. While the signal from each GROUP
bus is always fed into the corresponding GROUP OUT jack (see
page 20), you are also free to use the TO ST and AFL switches to
selectively feed these groups into the ST and AFL buses.
1 PAN Control
If you are feeding the signal from the GROUP bus into the ST
bus (that is, if the corresponding TO ST switch (
2) is on), this
knob controls how the signal is positioned on the ST L/R lines.
2 TO ST Switches
For each group: If the switch is on ( ), the mixer feeds the
signal from the GROUP bus into the ST bus, after first passing
the signal through the GROUP fader (
4) and the PAN control
(
1).
3 AFL (After-Fader Listen) Switches
Feeds the corresponding GROUP OUT signal into the AFL
bus, so that this signal can be monitored at the PHONES jack.
4 Group Faders
Each fader adjusts the level of the signal that is fed to the corre-
sponding GROUP OUT jack.
■ SEND Section
This section adjusts the levels and controls the flow of the signals
from the six AUX buses and the two EFFECT buses. Each of these
signals flows to the corresponding SEND output jack (to
AUX1–AUX6, EFF1, and EFF2, respectively).
1 AUX Controls (AUX1 to AUX6)
Each knob adjusts the level of the signal from the indicated
AUX bus into the corresponding AUX SEND jack.
2 Effect Controls (EFF1, EFF2)
Each knob adjusts the level of the signal from the indicated
EFFECT bus into the corresponding EFFECT SEND jack and
also into the corresponding internal digital effect.
For each channel, you use the channel’s AUX5/6
switch (see page 11) to select between feed into the
AUX5 and 6 buses or feed into the EFFECT 1 and 2
buses. If the switch is on ( ), the signal goes to
the AUX5 and AUX6 SEND jacks. If the switch is off
( ), the signal goes to the EFF1 and EFF2 SEND
jacks.
3 AFL (After-Fader Listen) Switches
For each AUX and EFFECT bus: Use this switch to feed the
corresponding AUX SEND or EFF SEND signal into the AFL
bus. Feeds the corresponding AUX SEND or EFF SEND signal
into the AFL bus, so that this signal can be monitored at the

Each knob adjusts the level of the signal from the correspond-
ing RETURN jack into the corresponding AUX bus (AUX1 to
AUX4). If you are inputting a stereo signal, the L and R signals
are mixed before moving to the AUX buses.
2 ST Control
Adjusts the level of the signal from the corresponding
RETURN jack into the ST bus. If you are inputting a stereo
signal, the L signal goes into the ST L line and the R signal
goes into ST R line. If you are inputting a mono signal, the
same signal is fed to both ST L and ST R.
3 PFL (Pre-Fader Listen) Switch
Use this switch to feed the corresponding RETURN signal,
taken from before the ST and AUX Mix controls, into the PFL
bus, so that you can monitor the signal at the PHONES jack. To
turn the PFL feed on, press the switch in ( ).

■ INTERNAL DIGITAL EFFECTS Section
You use this section to control the dual internal effects processor: to
select the two effect types, to set the effects on or off, and to adjust
the related signal levels and flows.
1 PROGRAM Dials
This dial sets the effect type for the corresponding internal dig-
ital effect. For information about the effect types, see page 24.
2 PARAMETER Controls
This knob sets the parameter value for the corresponding inter-
nal digital effect. The setting applies to the currently selected
effect type.
The mixer saves the last value used with each effect
type. When you change to a different effect type, the
mixer automatically restores the value that was pre-
viously used with the newly selected effect (regard-
less of the current position of the Parameter Control
knob). These parameter values are retained even
after power-off.
3 AUX PRE Controls (1 to 4)
Each knob adjusts the level of the effected sound into the corre-
sponding AUX bus (AUX1 to AUX4).
4 TAP Button and Indicator
This feature lets you set the delay time for internal EFFECT 2
by tapping on the button. The feature only works if you have
set the effect type for EFFECT 2 to [16] TAP DELAY. To set
the delay time, tap on the button at the appropriate interval. The
mixer measures the interval between the last two taps and sets
this as the delay time. Continue tapping as necessary until you
get the timing right.
The mixer retains the last time setting even after power goes
off, and restores this setting the next time you set the effect
type to TAP DELAY. The indicator next to the button flashes in
sync with the delay time.
5 ON Switches
This switch turns the corresponding internal digital effect on
() or off ( ).
6 PFL (Pre-Fader Listen) Switches
Use this switch to feed the corresponding digital effect signal,
taken from before the EFFECT RTN fader, into the PFL bus, so
that you can monitor the signal from the PHONES jack. To
turn the PFL feed on, press the switch in ( ).
The signal will not feed into the PFL bus if the
effect’s ON switch (5) is turned off.
7 GROUP Switches
Set the switch on ( ) to feed the corresponding internal digi-
tal effect signal into the corresponding GROUP buses. The top
button feeds the signal to Groups 1 and 2; the lower button
feeds it to Groups 3 and 4.
8 ST Switches
Set this switch on to feed the corresponding internal digital
effect signal into the ST bus.
9 EFFECT RTN faders (1, 2)
This fader adjusts the level of the effected sound into the ST
and GROUP buses.

■ METER/PHONES Section
You use these meters to view various signal levels: the levels to the
ST OUT jacks, the PFL and AFL levels, and the levels to the
GROUP OUT jacks. The PFL or AFL signals indicated by these
meters can be monitored through the PHONES jack.
1 POWER Indicator
Lights up when the mixer’s power is on.
2 STEREO Level Meters
If the GROUP switch (4) is off, the left and right meters show
the level to the ST OUT L and R jacks, respectively. If the
GROUP switch is on, the left and right meters show the level to
GROUP OUT jacks 1 and 2, respectively. The “0” position cor-
responds to the standard level. The PEAK indicator lights up
red when the level hits the clipping point.
3 PFL-AFL Level Meters
If the GROUP switch (4) is off, these meters show the levels
to the PHONES jack. If the GROUP switch is on, the left meter
shows the level to GROUP OUT jack 3 and the right meter
shows the level to GROUP OUT jack 4. The “0” position corre-
sponds to the standard level. The PEAK indicator comes on red
when the level hits the clipping point.
If signals are present on both the PFL and AFL
buses, the PHONES jack will output the PFL signal
only. Accordingly, these meters will indicate only the
PFL level.
4 GROUP Switch
Selects whether the meters show the GROUP levels or the ST
and PFL/AFL levels. If the switch is on ( ), the four meters
show the levels to GROUP OUT jacks 1 to 4, in order. If the
switch is off ( ), the meters operate as described above.
5 PHONES Jack and Control
• PHONES Jack
An unbalanced stereo phone output jack, for connection to
headphones.
• PHONES Control
Controls the level of the signal output to the PHONES jack
for monitoring.
The PFL-AFL level meter (3) shows the level of the
signal monitored through the PHONES jack.
■ 2TR INPUT Section
This section adjusts the signal that is input from the 2TR IN jack
(see page 20).
1 2TR IN Control
Adjusts the level of the signal from the 2TR IN jack into the ST
bus.
2 PFL (Pre-Fader Listen) Switch

■ CHANNEL I/O Section
1 Monaural-Channel Input Jacks
(MG32/14FX: CHs 1 to 24, MG24/14: CHs 1 to 16)
• INPUT A
These are balanced XLR input jacks.
• INPUT B
These are balanced phone input jacks. You can connect either
balanced or unbalanced phone plugs to these jacks.
On any given channel, you may use either INPUT A
or INPUT B, but not both. If you connect to both of
these inputs, only INPUT B will be effective.
2 INSERT I/O Jacks
These are unbalanced TRS (tip, ring, sleeve) phone-type bidi-
rectional jacks. You can use these jacks to connect channels to
devices such as graphic equalizers, compressors, and noise fil-
ters.
Connection to an INSERT I/O jack requires a spe-
cial separately-sold insertion cable such as illus-
trated below.
3 Stereo-Channel Input Jacks
(MG32/14FX: CHs 25/26, 27/28, 29/30, 31/32)
(MG24/14FX: CHs 17/18, 19/20, 21/22, 23/24)
• Phone jacks
(MG32/14FX: CHs 25/26, 27/28, 29/30, 31/32)
(MG24/14FX: CHs 17/18, 19/20, 21/22, 23/24)
These are unbalanced phone input jacks. You can use each
pair of jacks to input a stereo signal. Feed the L signal into
the odd-numbered channel, and the R signal into the
even-numbered channel.
• RCA-pin jacks
(MG32/14FX: CHs 29/30, 31/32)
(MG24/14FX: CHs 21/22, 23/24)
These are unbalanced RCA-pin input jacks. You can use each
pair of jacks to input a stereo signal. Feed the L signal into
the odd-numbered channel, and the R signal into the
even-numbered channel.
• Where a channel provides both a phone jack and
an RCA pin jack, you may use either one of these
jacks but you may not use both at the same time.
Please connect to only of these jacks on each
channel.
• Some of the phone jacks (MG32/14FX: CHs
25/26, 27/28; MG24/14FX: CHs 17/18, 19/20)
also support monaural input. Specifically, if you
input only into the L (MONO) jack of either pair
(while leaving the R jack empty), the mixer will
propagate the same signal through both the L
(MONO) and R inputs.

■ MASTER I/O Section
1 RETURN Jacks (1, 2)
These are unbalanced phone input jacks. The signal into each
of these jacks feeds into the ST bus and into AUX buses 1 to 4.
These jacks are typically used to receive a return signal from an
external effector (reverb, delay, etc.).
These jacks can also be used as an auxiliary stereo
input. If you connect to the L (MONO) jack only, the
mixer will recognize the signal as monaural and will
propagate the identical signal from both L and R
jacks.
2 2TR IN Jacks
These unbalanced RCA-pin input jacks can be used to input a
stereo sound source. The signal into each of these jacks feeds
into the ST bus. Use these jacks when you want to connect a
stereo sound source (such as a CD player or DAT deck) directly
to the mixer for monitoring.
3 REC OUT (L, R) Jacks
These are unbalanced RCA-pin output jacks. By connecting
these jacks to an external recorder, you can record the same
signal that is being output from the ST OUT jacks.
The signal from these jacks is not adjusted by the
ST master fader and is not affected by input or out-
put at the INSERT I/O jacks. When using these
jacks to record, adjust the level as necessary at the
external recording device.
4 SEND Jacks
•AUX Jacks (1 to 6)
These are impedance-balanced phone jacks. These jacks out-
put the signals from AUX1 to AUX6, respectively. You use
these jacks, for example, to connect to a monitoring system,
effector, or other such equipment.
• EFFECT Jacks (1, 2)
These impedance-balanced phone jacks output the signals
from the EFFECT buses. You would typically use these jacks
to connect to an external effector.
5 GROUP INS I/O Jacks (1 to 4)
These are unbalanced TRS (tip, ring, sleeve) phone-type bidi-
rectional jacks. You can use these jacks to connect individual
groups to devices such as graphic equalizers, compressors, and
noise filters.
Connection to an INSERT I/O jack requires a spe-
cial separately-sold insertion cable such as illus-
trated below.
6 GROUP OUT Jacks (1 to 4)
These are impedance-balanced phone output jacks. These jacks
output the signals from GROUP buses 1 to 4. Use these jacks to
connect to the input jacks of MTRs, external mixers, and other
such devices.
