							 COMPUTEr CONNECTION
1.  CONNECTINg  ThE VMS4 TO yOUr PC
Connect the VMS4 to your PC by using the USB ports located on the rear of the VMS4 and your PC. Connect 
the supplied USB cable to the USB port on the rear of the VMS4, and the other end connects to the USB port 
on  your  computer. NOTE:  Before  connecting  your  VMS4  to  your  computer  or  laptop,  we  highly  recom-
mend that you install the provided software. The Virtual DJ version included with this product  is specifi-
cally tailored to work with the VMS4 with no setup required. The setup of other non-factory authorized 
drivers and software is far more complex and in some instances not as reliable.

							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 crossfader (part# Z-FF-8). If you wish to upgrade to an 
Innofader, please order the Innofader model which comes with the VMS4 plade cover to protect the 
Innofader from damage during handling of the VMS4. 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 
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.
