Understanding the controls of your MX12 mixer is key to achieving optimal sound.

Channel Controls

• GAIN Controller: Adjusts the input sensitivity for each channel. Set this to an appropriate level to avoid clipping (indicated by the 'PK' light).
• EQ (Equalization): Each channel has three bands: 'HI' (treble), 'MID' (midrange), and 'LOW' (bass). Use these knobs to shape the tone of each input source.
• AUX Controller: Controls the send level to the auxiliary output, useful for monitor mixes or external effects.
• FX Controller: Adjusts the send level to the internal DSP effects processor.
• PAN Controller: Positions the sound of the channel within the stereo field (left to right).
• MUTE Button: Mutes the individual channel. The 'MUTE' light illuminates when active.
• VOLUME FADER: Controls the overall output level of the individual channel.

DSP Effects

The MX12 features 256 DSP effects. Use the 'ENTER' knob to scroll through and select different effects. The selected effect number will be displayed on the screen. Adjust the 'FX' knob on individual channels to send signal to the effects processor, and use the main 'EFFECTS' fader to control the overall effect return level.

USB/MP3 Player

Insert a USB drive into the 'USB OTG' port. Use the playback controls (play/pause, next/previous, mode) to navigate and play audio files. The display will show track information and playback status. For PC recording/playback, ensure the mixer is selected as the audio input/output device in your computer's sound settings.

Main Output Controls

• MAIN Faders (L/R): Control the overall volume of the main stereo output.
