  • Patikrinkite, ar GAIN controls are set appropriately and the CLIP šviesos diodas is not constantly lit.
  • If using condenser microphones, ensure PHANTOM POWER (+48V) yra aktyvuotas.
  • Patikrinkite garsumo lygius savo ampkeltuvai arba maitinami garsiakalbiai.
• Iškraipytas garsas:
  • Sumažinti GAIN control for the offending channel if the CLIP šviesos diodas is frequently flashing.
  • Lower the channel LYGIS or PAGRINDINIS MIKSAS lygiu.
  • Check the input source for distortion before it reaches the mixer.
• Dūzgimas arba triukšmas:
  • Ensure all audio cables are properly shielded and in good condition.
  • Try to isolate the mixer's power supply from other noisy electrical devices.
