  • Regularly clean the system with a soft cloth and mild detergent
  • RCA (Phono and Line)
  • XLR ( Mic and Line)
  • 1/4" TRS (Headphone and Footswitch)

B. The Mixer Section (Center)

  • Channel Input Selectors (CH1 / CH2): A 3-way toggle: Line (for CD/Bluetooth), Phono (for turntable), or USB (for flash drive). Manual warning: Never leave a turntable on "Line" – it will overload the preamp.
  • Gain (Trim) Knobs: Set to "12 o'clock" during initial setup. The manual provides a calibration trick: Play a loud track and adjust Gain until the "Peak" LED flickers red only on bass hits.
  • 3-Band EQ: High (+12dB to -26dB), Mid, Low. The "Kill" feature (-26dB) is fully subtractive, meaning at minimum, the frequency disappears completely.
  • Crossfader: Curves cannot be adjusted on this model (sharp cut is default). Manual recommends lubricating the crossfader rails every 6 months.
  • Most software allows you to adjust "Jog Wheel Sensitivity" in the controller settings.
  • If the wheel is loose physically, it may require cleaning. Use compressed air to blow out dust from under the wheel rim.
