Due to fog residue, smoke, and dust, cleaning the mixer should be carried out periodically to residue 
build up.  
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.   Cleaning should be carried out every 30-60 days to prevent heavy built up.
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 Swapable” 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.   Disconnect the mixers main power supply
2.   Using a number two Phillips screw driver, unscrew the each of the stainless steel retain screws    
 

that hold the crossfader in place.

3.   Gently remove the crossfader from its seated position. You may need to wiggle the crossfader    
 

slightly to remove it.

4.   After removing the crossfader, disconnect the ribbon cables that attach the crossfader to the  

 

       PC board. Grasp the crossfader by its base and pull each of the ribbon cables by its connector   
 

not the actual cables. The connector is designed to only fit one way, so don’t worry about the       

    connectors orientation.
5.   Connect the new crossfader to the ribbon cable and replace in reverse order.
