Please  make  any  connections  before  you  plug  the  mixer  in.  Be  sure  the  Power  switch  is  in  the  OFF 
position before connecting other devices to the mixer. All fader and volume controls should be set to 
0  or  minimum  position,  before  the  device  is  switched  on.  If  the  device  has  been  exposed  to  drastic 
temperature fluctuation (e.g. after transportation), do not switch on the mixer immediately. The arising 
condensation of water might damage your device. Leave the device switched off until it has reached 
room temperature.
Operating Determinations:
•  When installing this mixer, please make sure that the device is not exposed to extreme heat,  
 moisture or dust!
• There should not be any cables lying around. Doing so endangers you as well as others. 
• Do not operate the mixer in extremely hot (more than 30° / 100°F) or extremely cold (less than  
 5°C/40°F) surroundings. 
• Keep the unit out of direct sunlight and away from heaters.
• Operate the mixer only after becoming familiar with its functions. Do no\
t permit operation by  
 persons not qualified for operating the mixer. Most damages are the result of unprofessional  
 operation!

Quick  start:  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-D1 PRO 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 provide you with the most reliable product on the market by using only components 
constructed of the finest material.
Master LeveL (2) - Use this level control to set your master 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.
PHONO/LiNe seLectOr sWitcH  (7)  - 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  or  LINE. 
Use  “LINE”  for  line  level    devices  such  as  CD  players  and  tape  decks.  Use  “PHONO”  for  magnetic 
turntables only (DJ turntables).
cHaNN eL  G aiN  Leve L  (4)  - The  channel  gain  levels  are  not  to  be  used  as  volume  controls. 
Never use the channel trim to set the output volume. These controls are used to aid in distortion con-
trol. 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.
 
HeaDPHON es (10) - To avoid damaging your headphones always be sure the headphone volume 
level (1) is set to minimum before plugging them in. To avoid sever hearing damage, never put the head-
phone on without making sure the headphone level is turned down.
Mic  (13)  - The  mic  connector  uses  a  1/4”  plug  that  allows  you  to  connect  a  1/4”  unbalanced  mic 
cord. The mic also has an independent volume control. Always leave the mic level to it’s minimum level 
when not in use.
Q-start  Feature  - This  function  works  in  conjunction  with  a  compatible  American  Audio  
“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.

1.  cue Leve L vOL uM e  cON trOL - This knob adjusts the headphone volume output level. Turning 
the knob in clockwise direction will increase headphone volume output.
2. Master  vOLuM e cON trOL - This rotary knob is used to control the master output level (volume). 
To  avoid  distorted  output  try  to  maintain  an  average  output  signal  level  +4  dB.  Be  sure  this  volume 
control is always set to zero before turning the unit on.
3. Mic LeveL - This rotary knob is used to control the microphone volume output level. Turning the 
knob in a clockwise direction will increase volume output.
4.   cHaNNeL GaiN  cONtrOL - This adjustment is used to adjust the audio source signal input gain 
for  a  channel.  Never  use  the  gain  control  to  adjust  a  channels  output  volume.  Setting  the  gain  level 
properly  will  ensure  a  clean  output  signal.  An  improper  gain  level  adjustment  will  send  a  distorted 
signal throughout the entire audio line which may damage speakers and amplifiers. To properly set a 
channels the gain level control:

series  professional  CD  player.  When  used  with  a  compatible  "Q"  series  CD  player,  you  can  use  the 
CROSSFaDER  (12)  to  start  and  stop  the  CD  Player.  The ON/OFF  “Q”  START  switch  activates  this 
FADER “Q” START feature. When in the ON position, the FADER “Q” START function allows the fader 
to return automatically to the CD players preset cue point by simply sliding the CROSSFaDER (12) 
back and forth.
   For example, each time you slide the crossfader to the far left, the "Q" start function will trigger 
   the play mode for any CD player connected to PLayER  CONTROL  "a". Play will begin at 
   that unit's last set cue point. Turn the "Q" ON/OFF SWITCh to the OFF position to disengage 
   “Q” Start function and resume normal fader operation.

(12) to  right  position  will  cut  that  channels  volume  to Master  VoluMe  leVel  (2). The  reverse  is
