Precautions
Warnings
Cautions
• Do not allow water to enter this unit or allow the
unit to become wet. Fire or electrical shock may
result.
• 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.
• 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.
• 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 scratch, bend, twist, pull, or heat the power
cord. A damaged power cord is a fire and electrical
shock hazard.
• Do not touch the power plug with wet hands.
Doing so is a potential 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.
Operating Notes
• Using a mobile telephone near this unit may
induce noise. If noise occurs, use the telephone
away from the unit.
• 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.
• 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.
• 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.

Introduction
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
• 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.
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 TAPE IN jacks and REC OUT jacks let you
easily connect a master recorder for recording or
playback.
• 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.
Contents
• 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.

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.

0Group select 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.
When the switch is pressed in, the pre-fader sig-
nal will be sent to the corresponding pair of AUX
buses. When the switch is in the out (up) posi-
tion, the post-fader signal will be sent.
These switches send the signal of the input chan-
nel to GROUP buses 1–4. When the 1–2 switch is
on (pressed in) the signal will be sent to GROUP
bus 1/2. When the 3–4 switch is on, the signal will
be sent to GROUP bus 3/4.
AST (stereo) switch
This switch sends the signal of the input channel
to the ST bus. When this switch is on, the signal
will be sent to the ST bus.
8PAN control
This adjusts the left/right position at which the
input channel signal will be sent to the ST (ste-
reo) bus, GROUP bus 1/2, and GROUP bus 3/4.
BPFL (pre-fader listen) switch
This switch sends the pre-fader signal to the PFL/
AFL bus, allowing you to monitor it through
headphones or monitor speakers. When this
switch is on, the pre-fader signal of the input
channel can be heard from the C-R OUT jacks
and the PHONES jack, even if the ON switch
(9) is off.
9ON switch
This switches the input channel on/off. When
this switch is turned off, the signal of the input
channel will not be sent to the ST bus, GROUP
buses, or AUX buses. However even if this switch
is off, you can use the PFL switch (B) to monitor
the signal from the C-R OUT jacks or the
PHONES jack.
CChannel fader
This fader adjusts the input level of the input
channel. The position of the channel fader will
affect the level of the signal that is output from
the ST bus, GROUP buses 1–4, and AUX buses 1–
6 (except when the PRE switch is on for AUX
buses 3–6).

1–8 on the GF12/12}
These are phono jacks (unbalanced) that output
the signal from the ST bus, with a nominal level
of –10 dBV. This output signal is not affected by
external effect processors connected to the ST
INSERT I/O jacks (B) or by the position of the
MONO control section). The pin wiring is shown
in the following diagram.
These are XLR-3-31 type input connectors (bal-
anced) for the monaural input channels. Nomi-
nal input level is –16 dB to –60 dB when the pad
section) is off, and +10 dB to –34 dB when the

These are 1/4" phone input jacks (unbalanced)
for the stereo input channels, with nominal level
of +10 dB to –34 dB. When using these as mono
channels, insert a plug only into the 21L/23L
jacks {13L/15L on the GF16/12, or 9L/11L on the
GF12/12}. The pin wiring is shown in the follow-
ing diagram.
8INPUT 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
same channel. Phantom power is not supplied to
the INPUT B jacks. The pin wiring is shown in
the following diagram.

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
inputting a monaural signal, connect a plug only
to the 1L or 2L jack. The pin wiring is shown in
the following diagram.
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),
input channel section) to select whether INPUT
jack A or B will be used.
