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 fi t 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 cross-
fader by its base and pull the ribbon cable by its connector not the actual cable. The connector is
designed to fi t 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.
4. Reassemble in reverse order.
