    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.
  • Page 5: Pan Control

    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).
  • Page 6: Stereo Input Channels

    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.
  • Page 7: Channel Fader

    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.
  • Page 8: Master Section

    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.
