6. Operating Instructions

6.1 Adjusting Channel Levels

1. Set all channel faders and the MAIN L/R faders to their lowest position before starting.
2. Connect your audio source to a channel input.
3. Slowly increase the 'GAIN' knob for that channel until the 'PEAK' LED flashes occasionally during the loudest parts of the signal. Then slightly reduce the gain until the LED no longer flashes.
4. Slowly raise the channel fader to the desired level.
5. Adjust the 'MAIN L/R' faders to control the overall output volume. Monitor the 'PEAK/LEVEL' indicators to avoid clipping.

6.2 Using the Equalizer (EQ)

1. Channel EQ (HI/MID/LOW): Use these knobs on each channel to fine-tune the tone of individual inputs. Adjust 'HI' for treble, 'MID' for mid-range, and 'LOW' for bass frequencies.
2. 7-Band Graphic Equalizer: Use the sliders on the 'STEREO GRAPHIC EQUALIZER' section to adjust the overall frequency response of the main mix. This allows for global tone shaping.

  • Check if any 'MUTE' buttons are active on channels or the main output.
  • Confirm that connected speakers/amplifiers are powered on and functioning.
• Distorted Sound:
  • Reduce the 'GAIN' knob on the input channel if the 'PEAK' LED is constantly lit.
  • Lower the channel faders or 'MAIN L/R' faders if the output level indicators are consistently in the red.
  • Check the EQ settings; extreme adjustments can cause distortion.
• Bluetooth Connection Issues:
  • Ensure the mixer is in 'BLUE' mode (indicated on the display).
  • Make sure Bluetooth is enabled on your device and it's within range.
