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 understand-
ing of the unit. The Q-D5 MKII is part of American 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 pro-
vide you with the most reliable product on the market by using only components 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 speakers. Remember that a distorted signal from you mixer will only be 
multiplied throughout your system.
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.
