Due to fog residue, smoke, and dust, cleaning the mixer should be carried out periodically to optimize 
light output. 
 
1.   Use normal glass cleaner and a soft cloth to wipe down the outside casing.
2.   Use a cleaner specially designed for electronics to spray in and around the knobs and switch.    
  This will reduce small particle built up that can effect the proper operation of the mixer. 
3.   Clean should be carried out every 30-60 days.
4.  Always be sure to dry all parts completely before plugging the   mixer in.
Cleaning frequency depends on the environment in which the mixer operates (i.e. smoke, fog residue, 
dust, dew).
The crossfader is “Hot Swappable” which means it may be replaced at any time, even when power is 
applied.  Only  replace  with  American  Audio  Part  Feather  Fader  Plus.  Replacing  with  any  other  model 
fader may seriously damage your mixer.
Replacing the Crossfader:
1.   Using a number two Phillips screw driver, unscrew the each of the stainless steel retaining    
  screws   that hold the crossfader in place.
2.   Gently remove the crossfader from its seated position. You may need to wiggle the crossfader    
  slightly to unseat it.
3.   After removing the crossfader, disconnect the ribbon cable that attaches the crossfader to the    
  PC board. Grasp the crossfader by its base and pull the ribbon cable by its connector not the    
  actual cables. The connector is designed to fit one way, so don’t worry about the connectors    
  orientation.
4.   Connect the new crossfader to the ribbon cable.
5.  Reassemble in reverse order.
Changing/Replacing the Transformer Switch:
1.  Disconnect the mixer’s main power supply.
2.   Using a number two Phillips screw driver, unscrew each of the larger retainer screws that hold    
  the transformer switch in place.
3.   To replace: disconnect the ribbon cable that attaches the switch to the PC board. Grasp the    
  crossfader by its base and pull the ribbon cable by its connector not the actual cable. The con-   
  nector is designed to fit one way, so don’t worry about the connectors orientation.
3.  To augment transformer orientation: Pull the switch out and turn to the desired position.
