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. Replace with American Audio VMS4.1 crossfader (part# Z-FF-8). If you wish to upgrade to 

an Innofader, please order the Innofader model which comes with the VMS4.1 plade cover to protect 

the Innofader from damage during handling of the VMS4.1. If you upgrade to the Innofader, please 

make sure the power is off before upgrading to limit the chance of damage to the Innofader and/or 

VMS4.1 during installation. Replacing with any other model fader may seriously damage your mixer.

Replacing the Crossfader:

1.   Disconnect the mixers main power supply

2.   Using a Phillips screw driver, unscrew the two outside screws on each side that hold the cross   

 

fader assembly in place.

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

 

crossfader slightly to remove it.

4.   After removing the crossfader assembly, disconnect the ribbon cable that attaches the cross 

 

 

fader to the PC board. Grasp the crossfader by its base and pull the ribbon cable by its con 

 

 

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

 

 

about the connectors orientation.

5.  Unscrew the two inner screws that connect the crossfader to the crossfader plate.

6.   Connect the new crossfader to the ribbon cable and replace in reverse order.
