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.

Front and rear panel

This section explains the names and functions of each section of the GF24/12, GF16/12, and GF12/12.

The functionality of these mixers is grouped into ten sections. These are the two channel control sections, seven master control sections, and the rear panel connectors. Their functions will be explained sequentially.

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.

C

Channel 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).
