Quick start instructions  
American Audio would like to thank for your purchase of  
this great product. For those of you that are to impatient  
to read the entire user manual we have compiled these  
quick start instructions. We hope that you will at least read  
through these instructions to familiarize yourself with the  
basic understanding of the unit. The Q-D5 is part of Ameri-  
can Audio’s continuing evolution in audio technology. This  
unit has been built and designed with the typical DJ in  
mind, by DJ’s. We have attempted to provide you with the  
most reliable product on the market by using only compo-  
nents made from quality products.  
MASTER LEVEL - Use this level control to set your volume  
output. Try never to send an output of more than +4dB to  
your system. Signal at levels higher than this will start to  
distort and may cause damage to your system and speak-  
ers. Remember that a distorted signal from you mixer will  
only be multiplied throughout your system.  
DJ SKILZ  
SIGNATURE SERIES  
CHANNEL GAIN LEVEL - The channel trim levels are not  
to be used as volume controls, never use the channel gain  
to set the output volume. These controls are used to aid in distortion control. Use these control to  
preset your signal level before the crossfader. With your channel faders in the maximum position, use  
the channel trim level to set an average output level of about +4dB on you master level meter.  
HEADPHONES - To avoid sever hearing damage, always be sure the headphone level is set to mini-  
mum before plugging them in. Never put the headphone on without making sure the headphone level  
is turned down.  
MIC - The mic connector uses a 1/4” jack unbalanced connector. The DJ mic has an independent  
volume control. When feedback occurs when using the mic, try lowering the “low” level this may  
reduce the feedback. Always leave the mic level to it’s minimum level when not in use.  
PHONO/AUX SWITCH (27) - This switch is used to change the selected input from phono level to  
line level and vice versa. Channels 1 and 2 may be switched PHONO/AUX or LINE. The selectors for  
AUX1/PHONO1 and AUX2/PHONO2 are on the rear panel.  
Q-START FEATURE - This function works in conjunction with a compatible American Audio or Ameri-  
can DJ “Q”Start CD player. When used with a compatible CD player, you can use the crossfader to  
start and stop the CD Player with the slide of the fader. The ON/OFF “Q ”START switch activates this  
FADER “Q ”START feature.  
CROSSFADER CURVE ADJUSTMENT- This rotary knob is used to change the way the crossfader  
will operate. The crossfader can operate in three different modes, NORMAL CURVE, QUICK CURVE  
and any variation of the two. (Quick Curve usually used for crabbing).  
CHANNEL FADER CURVE ADJUSTMENT - This rotary knob is used to change the way the channel  
fader will operate. Each channel has a Curve adjustment. The curve on the faders adjust from long or  
short or any variation of the two.  
REVERSE FUNCTION - Both the crossfader and the channel faders will reverse function when the  
reverse switch is activated.

Q-D5™  
Cleaning  
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).  
Q-D5™  
Cross Fader Replacement  
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 fit 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 fit one way, so don’t worry about the connectors orientation.
