  • Page 2 N or coloured BLACK. The wire which is coloured BROWN must be connected to the terminal which is marked with the letter L or coloured RED. * This applies only to products distributed by YAMAHA KEMBLE MUSIC (U.K.) LTD.
  • Page 3 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.

    • 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 { }.

  • Page 5: Front And Rear Panel

    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 chan- nel control sections, seven master control sections, and the rear panel connectors. Their functions will be explained sequentially.

  • Page 6: Channel Controls

    3–4 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.
  • Page 7 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. When the switch is pressed in, the pre-fader sig- nal will be sent to the corresponding pair of AUX buses.
  • Page 8 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 sig- nal.
  • Page 9 (MONO) INPUT A *2,*4 *1,*3 INPUT B *2,*4 GF12/12 GF16/12 GF24/12 Group select switches 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.

  • Page 10: Master Controls

    Front and rear panel Master controls GROUP section This section individually controls the output sig- nal of GROUP buses 1–4. The signal that passes through the GROUP 1–4 output channels can be sent individually from the GROUP OUT 1–4 output jacks (page 20, D in the connector sec- tion), and can also be sent to the ST bus or PFL/ AFL bus by using the TO ST switch (group sec- tion 2) and AFL switch (group section 4).
  • Page 11 AUX section This section individually controls the output sig- nals of AUX buses 1–6. The signal that has passed through the AUX 1–6 output channels can be sent individually to the AUX OUT jacks 1–6 (page 17, 1 in the connector section), and can also be sent to the PFL/AFL bus by using the AFL switch (2 in the AUX section).
  • Page 12 Front and rear panel STEREO/MONO section This section separately controls the STEREO OUT jacks (page 17, 3 in the connector section) which are the main output of the mixer, and the MONO OUT jack (page 17, 2 in the connector section) which outputs a monaural mix of the STEREO OUT output.
  • Page 13 AUX RETURN section This section controls the two stereo AUX returns. By using the L and R jacks of AUX RETURN 1/2 (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.
  • Page 14 Front and rear panel TAPE IN section This section controls the signal that is input from the TAPE IN jacks (page 17, 4 in the connector section). The input signal from the TAPE IN jacks can be sent directly from the ST bus, and can also be monitored from the C-R OUT jacks or PHONES jack.
  • Page 15 TAPE IN switch This selects the signal that will be monitored by the C-R OUT jacks and PHONES jack: either the PFL/AFL bus, or the TAPE IN jacks. C-R MONITOR LEVEL (control room moni- tor level) control This adjusts the level of the signal that is sent to the C-R OUT jacks.

  • Page 16: Meter Section

    Front and rear panel Meter section This is a peak level meter that shows (according to the setting of the METER SELECT switch, page 14) the output levels of GROUP buses 1–4, the ST bus, and the PFL/AFL bus, and the input level of the TAPE IN jacks.

  • Page 17: Connectors

    Connectors POWER ON/ OFF MONO OUT +4dBV AUX OUT jacks 1–6 These are TRS phone output jacks (balanced) that individually output the signals of AUX buses 1–6. Nominal level is +4 dB. These jacks can be connected to your foldback system or to the inputs of external effect processors.
  • Page 18 +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. 1/4" phone plug INPUT A jacks 1–20 {1–12 on the GF16/12,...
  • Page 19 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.
  • Page 20 Front and rear panel ST INSERT I/O jacks These are TRS phone input/output jacks for inserting external effect processors between the ST bus and the STEREO fader. The nominal input/output level is 0 dB. The pin wiring is shown in the following diagram. Tip (send) Ring (return) 1/4"...
