Precautions
Warnings
• Do not allow water to enter this unit or allow the
unit to become wet. Fire or electrical shock may
result.
• Connect this unit’s power cord only to an AC out-
let of the type stated in this Owner’s Manual or as
marked on the unit. Failure to do so is a fire and
electrical shock hazard.
• Do not scratch, bend, twist, pull, or heat the power
cord. A damaged power cord is a fire and electrical
shock hazard.
• Do not place heavy objects, including this unit, on
top of the power cord. A damaged power cord is a
fire and electrical shock hazard. In particular, be
careful not to place heavy objects on a power cord
covered by a carpet.
• If you notice any abnormality, such as smoke,
odor, or noise, or if a foreign object or liquid gets
inside the unit, turn it off immediately. Remove
the power cord from the AC outlet. Consult your
dealer for repair. Using the unit in this condition is
a fire and electrical shock hazard.
• Should this unit be dropped or the cabinet be
damaged, turn the power switch off, remove the
power plug from the AC outlet, and contact your
dealer. If you continue using the unit without
heeding this instruction, fire or electrical shock
may result.
• If the power cord is damaged (i.e., cut or a bare
wire is exposed), ask your dealer for a replacement.
Using the unit with a damaged power cord is a fire
and electrical shock hazard.
• Do not remove the unit’s cover. You could receive
an electrical shock. If you think internal inspec-
tion, maintenance, or repair is necessary, contact
your dealer.
• Do not modify the unit. Doing so is a fire and elec-
trical shock hazard.
Cautions
• This unit has ventilation holes at the top and right
side to prevent the internal temperature rising too
high. Do not block them. Blocked ventilation holes
are a fire hazard.
• Hold the power cord plug when disconnecting it
from an AC outlet. Never pull the cord. A damaged
power cord is a potential fire and electrical shock
hazard.
• Do not touch the power plug with wet hands.
Doing so is a potential electrical shock hazard.
Operating Notes
• Using a mobile telephone near this unit may
induce noise. If noise occurs, use the telephone
away from the unit.
• XLR-type connectors are wired as follows:
pin 1: ground, pin 2: hot (+), and pin 3: cold (–).
• Insert TRS phone jacks are wired as follows:
sleeve: ground, tip: send, and ring: return.
• The performance of components with moving
contacts, such switches, rotary controls, faders,
and connectors, deteriorates over time. The rate of
deterioration depends on the operating environ-
ment and is unavoidable. Consult your dealer
about replacing defective components.

Introduction
—Owner’s Manual
Introduction
Thank you for purchasing the Yamaha GF24/12, GF16/12, or GF12/12 mixing console.
These mixers provide an ample twelve outputs, and are suitable for a wide variety of
applications ranging from concert sound reinforcement to installed systems. In order to
take full advantage of the mixer’s functionality and to enjoy years of trouble-free perfor-
mance, please read this manual carefully.
Note:
• This owner’s manual assumes that you are familiar with basic operation of a mixing
console and its specialized vocabulary.
• At points where the specifications of the GF24/12, GF16/12, and GF12/12 differ, the
specifications of the GF16/12 and GF12/12 are given in curly brackets { }.
Features of the system
• In addition to the main stereo outputs, this mixer
provides six AUX outputs plus four group outputs
(a total of 12 outputs). The AUX/GROUP outputs
can be used not only as sends to external effect
processors or to a multitrack recorder, but are also
ideal for creating separate foldback mixes for each
speaker and amp.
• The MONO OUT jack can be controlled indepen-
dently from the STEREO OUT jacks. Since a mon-
aural mix of the main output is sent from this
output, it can be used to extend a PA system.
• All input channels provide a high-pass filter, a
three-band EQ, and 60 mm faders.
• All input channels/AUX returns provide a PFL
switch, and AUX/group/stereo output channels
provide an AFL switch. You can audition input and
output sources at the touch of a button.
• All mono input channels provide balanced XLR
type and TRS phone jack connectors that accom-
modate a range of sources from mics to line level
devices.
• Switchable phantom power is provided. This can
supply DC +48 V power from the XLR type input
connectors to condenser mics and direct boxes
that require an external power supply.
• Two stereo input channels allow connection of
line-level equipment. 1/4" phone jack and phono
jack inputs can be selected by a switch.
• Two stereo AUX returns are provided. This allows
AUX return signals to be sent to an AUX bus or
GROUP bus as well as to the ST bus. These can
also be used as spare line level input jacks.
• An insert I/O jack is provided on each mono input
channel and on the ST bus, allowing you to insert
external effect processors as desired.
• The TAPE IN jacks and REC OUT jacks let you
easily connect a master recorder for recording or
playback.

Channel controls
■
Mono input channels
Here are the 20 {12, 8} mono input channels of
the GF24/12 {GF16/12, GF12/12}. The input
channel section processes the signal from the
input jacks of the connector section, and sends
the result to the GROUP buses, AUX buses, and
the ST bus.
1
Pad switch
This attenuates the input signal by 26 dB. The
pad is on when this switch is pressed in.
2
GAIN control
This adjusts the input sensitivity. The range of
levels that can be accommodated is –16 dB to
–60 dB when the pad switch (
1
) is off, and
+10 dB to –34 dB when the pad switch is on.
3
High pass filter switch
This is an on/off switch for the high pass filter
that cuts the frequency range below 80 Hz at a
slope of 12 dB/octave. The high pass filter is on
when the switch is pressed in.
4
PEAK indicator
This is an indicator that detects post-EQ clipping.
It will light 3 dB before clipping, indicating that
the signal is near the clipping level. If this LED
lights, lower the GAIN control (
2
).
5
EQ controls (HIGH/MID/LOW)
This is a three-band equalizer that boosts/cuts
each frequency band over a
±
15 dB range. The
center frequency and equalizer type for each
band is shown below.
The response is flat when the knob is in the “
▼
”
position.
6
AUX controls (1–6)
These knobs adjust the level at which the input
channel signal is sent to the AUX buses 1–6. AUX
controls 1 and 2 are fixed at pre-fader, and AUX
controls 3–6 can be switched between pre/post
fader using the PRE switch (
7
). When a knob is
in the “
√
” position, the level is “nominal”.

PRE switches
These switches select whether the pre or post -
fader signal will be sent to AUX buses 3–6. This
setting is switched in pairs: AUX 3/4 and 5/6.

(page 19, A in the connector section) in pairs,
you can input stereo signals. If only the L jack of
AUX RETURN 1/2 is connected, this can be used
as a monaural AUX return. The input signal from
AUX RETURN jack 1 can also be sent to GROUP
bus 1/2 and AUX bus 1/2, and the input signal
from AUX RETURN jack 2 can be sent to
GROUP bus 3/4 and AUX bus 3/4.
1 GROUP 1/2, AUX 1/2 mix controls
These controls adjust the level at which signals
from the AUX RETURN 1 jacks are sent to
GROUP bus 1/2 and AUX bus 1/2. When a stereo
signal is input, the signals of the L and R channels
will be sent to GROUP buses 1/2 and AUX buses
1/2 respectively. When a monaural signal is input,
the same signal will be sent to GROUP buses 1
and 2, and to AUX buses 1 and 2.
2 GROUP 3/4, AUX 3/4 mix controls
These controls adjust the level at which signals
from the AUX RETURN 2 jacks are sent to
GROUP bus 3/4 and AUX bus 3/4. When a stereo
signal is input, the signals of the L and R channels
will be sent to GROUP buses 3/4 and AUX buses
3/4 respectively. When a monaural signal is input,
the same signal will be sent to GROUP buses 3
and 4, and to AUX buses 3 and 4.
3 ST (stereo) controls
These adjust the level at which the input signals
from the AUX RETURN 1/2 jacks are sent to the
ST bus. The position of the stereo control knobs
does not affect the GROUP 1–4 and AUX 1–4
mix controls (1 and 2).

switch (page 6, 1 of the monaural input channel
section) is off, and +10 dB to –34 dB when the
pad switch is on.
When the PHANTOM +48 V switch (page 14, 1
of other controls/connectors) is on, DC +48 V
phantom power is supplied to pins 2/3. The pin
wiring is shown in the following diagram.
8 INPUT B jacks 1–20 {1–12 on the GF16/12,
1–8 on the GF12/12}
These are TRS phone input jacks (balanced) for
the monaural input channels. Nominal input
level is the same as for the INPUT A jacks (7).
Be aware that it is not possible to simultaneously
use both the INPUT A and INPUT B jacks of the

9 INSERT I/O jacks 1–20 {1–12 on the GF16/
12, 1–8 on the GF12/12}
These are TRS phone input/output jacks for
inserting external effect processors between the
EQ and channel fader of a monaural input chan-
nel. Nominal level is 0 dB. The pin wiring is
shown in the following diagram.
0 INPUT B jacks 21–24 {13–16 on the GF16/
12, 9–12 on the GF12/12}
These are phono input jacks (unbalanced) for the
stereo input channels. Nominal level is the same
as the INPUT A jacks (6). On the stereo input
channels, you can make connections both to the
INPUT A jacks (6) and the INPUT B jacks (0),
and use the A/B switch (page 8, 1 in the stereo
input channel section) to select whether INPUT
jack A or B will be used.
Be aware that in the case of the INPUT B jacks,
the channel cannot be used as a mono input
channel by inserting a plug only into 21L and
23L. (If only 21L or 23L are connected, the signal
will be sent only to the left channel.) The pin wir-
ing is shown in the following diagram.
A AUX RETURN jacks 1/2
These are 1/4" phone input jacks (unbalanced)
for connecting the stereo output of external effect
processors, etc. The nominal level is +4 dB. If
