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 out­let 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 inspec­tion, maintenance, or repair is necessary, contact your dealer.
• Do not modify the unit. Doing so is a fire and elec­trical shock hazard.
Precautions
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 environ­ment and is unavoidable. Consult your dealer about replacing defective components.

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 perfor­mance, 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 indepen­dently from the STEREO OUT jacks. Since a mon­aural 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 accom­modate 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.

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.
Pad switch
1
This attenuates the input signal by 26 dB. The pad is on when this switch is pressed in.
GAIN control
2
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.
High pass filter switch
3
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 ).
EQ controls (HIGH/MID/LOW)
5
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.
Band
HIGH 10 kHz shelving
MID 250 Hz–5 kHz peaking
LOW 100 Hz shelving
Center
frequency
Type
The response is flat when the knob is in the “▼” position.
AUX controls (1–6)
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”.
—Owner’s Manual
PRE switches
7
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 sig­nal will be sent to the corresponding pair of AUX buses. When the switch is in the out (up) posi­tion, the post-fader signal will be sent.
PAN control
8
This adjusts the left/right position at which the input channel signal will be sent to the ST (ste­reo) bus, GROUP bus 1/2, and GROUP bus 3/4.
ON switch
9
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.
Channel controls
Group select switches
0
These switches send the signal of the input chan­nel 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.
A
ST (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.
B
PFL (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.
Channel fader
C
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).

Here are the two stereo input channels provided by the GF24/12, GF16/12, and GF12/12. The INPUT 21/22 and 23/24 {13/14 and 15/16 on the GF16, and 9/10 and 11/12 on the GF12/12} jacks ( 6 and 0 of the connector section) are pairs of
3
connectors that let you control a stereo signal using one input channel. If a cable is connected only to the INPUT A 21L or 23L jack {13L or 15L on the GF16/12, or 9L or 11L on the GF12/12}, the source will be controlled as a monaural sig­nal.
