Introduction Thank you for choosing the Yamaha MC32/12 or MC24/12 mixing console. Please read this manual thoroughly to take best advantage of the console and extend its useful life. Notes: This manual has been written on the assumption that you already understand the basic operation and technical terminology of mixing consoles.
Front Panel Front Panel Monaural input channels 26dB GAIN –34 –16 –60 The MC32/12 {MC24/12} has 28 {20} monaural input channels. They are located on both sides of the master section and feature the same specifications. PEAK HIGH Pad switch –15 This switch is used to attenuate input signals by 26 dB.
ON switches These switches are used to turn on and off the signals routed from the input channel to MIX buses 1–4. Note: When these switches are set to off, no signals will be sent from the input channel to the corresponding MIX buses regardless of the setting of the switches in the Variable/Fix select section (see page 6).
Front Panel Stereo input channels The MC32/12 and MC24/12 provide two stereo input channel modules. Use the paired GAIN INPUT 13/14 and 15/16 jacks (see page 17, rear panel –34 connect signals only to the 13L (MONO) jack or 15L (MONO) jack, the same signal will be sent t the o M1–4 and ST buses.
PRE (Pre-fader) switches These switches are used to select pre- or post-fader for signals sent from the stereo input channel to MIX buses 5–10. Each switch is effective for one pair of MIX buses:5/6, 7/8, or 9/10. When you turn these switches on, the pre-fader signals are sent to the corresponding MIX bus pair.
Master Section Master Section Variable/Fix select section The MC32/12 and MC24/12 feature a GA (Group/Aux) diversity function, which enables you to use the MIX bus 1–4 signals as group bus signals or AUX bus signals. This section of the console allows you to select whether you wish to use MIX buses 1–4 as group buses or AUX buses.
Page 9
M1–M4 These modules function as output channels for either a group bus or an AUX bus, depending on the setting of the switches in the Variable/Fix select section. The MIX bus 1–4 signals that pass these output channels can be routed to MIX OUT 1–4 jacks, ST bus, AFL bus, and Matrixes 1/2.

ST (Stereo) section This section enables you to control the ST bus signals output from the ST1 OUT jacks (see page 17, rear panel POST ST1 (Post stereo 1) switch This switch toggles between pre- and post-fader for signals output from the ST2 OUT jacks. When you turn this switch on, signals that passed the ST fader are output from the ST2 OUT POST ST1 jacks.
Master Section AUX RETURN section The MC32/12 and MC24/12 provide four stereo AUX returns. Use the paired AUX RETURN 1–4 L/R jacks (see page 17, rear panel only to the AUX RETURN 1–4’s L jack to use the routing as a monaural AUX return.

Matrix 1–2 signals are output in monaural via the MATRIX OUT 1–2 jacks (rear panel M1–M4 level controls These control knobs enable you to adjust the input level of MIX bus...
Master Section C-R MONI (Control room monitor) section PHONES (headphones) section This section enables you to control signals monitored via the C-R MONITOR OUT jacks (see page 18, rear panel PHONES section Monitor source select switch This switch enables you to select the type of signal to monitor via the C-R MONITOR OUT PFL/AFL jacks and the PHONES jack.
TAPE IN section This section enables you to control line-level signals input from the TAPE IN jacks. Input signals from the TAPE IN jacks can be routed to the ST bus or directly to the C-R MONITOR OUT jacks and PHONES jack. ST (Stereo) control This control knob determines the level of input signals at the TAPE IN jacks that are sent to on the ST buses.
Master Section TALKBACK section This section is used to route talkback signals to the MIX buses and the ST bus. INPUT jack This XLR-3-31 unbalanced input jack is used to connect a talkback microphone with an output impedance of 50–600 . See the figure below for wiring.
METER SELECT section You can select the signal source to be displayed in the Meter bridge section. Source select switch This switch enables you to select the signal source to be displayed on the MATRIX (PFL•AFL/TAPE) meter (Meter bridge corner of the level meter. When the switch is set to PFL-AFL/TAPE ( The meter indicates either the PFL/AFL bus output level or the input level of the signals sent from the TAPE IN jacks, depending on the...
Rear Panel Rear Panel C-R MONITOR OUT MATRIX OUT +4dB ST INSERT I/O TAPE IN –10dBV REC OUT –10dBV INPUT A jacks 1–12, 17–32 {1–12, 17–24} These are balanced, XLR-3-31 monaural input jacks. Usually their nominal input levels range from –16 dB to –60 dB. However, when the pad switches (see page 2, front panel on, the nominal input levels range from +10 dB to –34 dB.
Page 19
INPUT jacks 13–16 These are unbalanced phone jacks for the stereo input channels, with nominal input levels ranging from –34 dB to +10 dB. If you are using the stereo input modules as monaural channels, connect a plug to 13L (MONO) or 15L (MONO) jack. See the figure on the right for wiring.

GA Diversity Function What is GA Diversity? GA Diversity is an output select function that allows you to use the MIX OUT jacks as group output jacks or AUX output jacks on the MC32/12 and MC24/12. You can route either MIX (Variable) bus signals or MIX (Fix) bus signals to the MIX OUT 1–4 jacks of the MC32/12 and MC24/12.
