American Audio Q-D5 MKII Stereo Amplifier User Manual


 
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 OF-1. Replacing with any other model fader may seri-
ously damage your mixer.
Replacing the Crossfader (Model OF-1):
1. Carefully remove all the knobs for the controls on the face of the unit, including fader knobs.
2. Using a # 2 Phillips screw driver, unscrew the four screw that secure the in the face plate in
place and remove the face plate.
3. Using a number two Phillips screw driver, unscrew the each of the stainless steel retaining
screws that hold the crossfader in place.
4. Gently remove the crossfader from its seated position. You may need to wiggle the crossfader
slightly to unseat it.
5. 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 t one way, so don’t worry about the connectors orientation.
6. Connect the new crossfader (model OF-1 only) to the ribbon cable.
7. Reassemble in reverse order.
Changing/Replacing the Transformer Switch:
1. Follow steps one and two above to remove the faceplate.
2. Disconnect the mixer’s main power supply.
3. Using a number two Phillips screw driver, unscrew each of the larger retainer screws that hold
the transformer switch in place.
4. 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
connector is designed to t one way, so don’t worry about the connectors orientation.
5. To augment transformer orientation: Pull the switch out and turn to the desired position.
6. Reassemble in reverse order.
