American Audio Mixer QD6 User Manual

							
musical instruments with stereo outputs such as Rhythm Machines or Samplers should also be con-
nected to LINE inputs. Turntables should only be connected to “Phono” inputs. The red colored RCA 
jack represents the right channel input and the white represents the left channel input.
23.  REC  OUT  -  This  is  a  low  current  unbalanced  output  source  designed  for  various  tape  and  CD 
recorders. The Record Out (REC OUT) level is dictated by the  CHANNEL FADER LEVEL (9)
, it is not 
influenced by the 
MASTER VOLUME CONTROL (4).
24. RCA MASTER OUTPUTS - The Master Output includes a pair of RCA  UNBALANCED JACKS (24). 
The RCA jacks send a low current unbalanced output signal. 
25 .  BALANCED  XLR  MASTER  OUTPUTS  -  The  Master  Output  includes  a  pair  XLR  Balanced 
JACKS  as well as a pair  RCA UNBALANCED JACKS (24)
. The 3-pin XLR jacks send a high current 
balanced output signal. These jacks should be used when you will be driving an amp or other audio 
equipment with a balanced input, or whenever you will be running a signal line greater than 15 feet. 
Always, use these jacks whenever possible.
26.  9V AC INPUT - Connect the included power supply to this input, or any other 9v power adapter .
27 . MAIN POWER SWITCH -
 This is the main power ON/OFF button. An L.E.D. located on the front 
of  the  mixer  will  glow  green  when  the  power  is  ON.  Before  main  power  is  applied,  be  sure  you  have 
made all connections to the mixer. Also be sure your amplifier(s) is(are) tuned off. Remember to avoid 
damaging pops, the mixer should be powered on first and turned off last.

28 . HEADPHONE OUTPUT JACK - This jack is used to connect your headphones to the mixer allow-
ing you to monitor the cue source. Use headphones only rated at 8 ohms to 32 ohms. Most DJ head
-
phones are rated at 16 ohm, these are highly recommended. Always be sure the  CUE LEVEL VOLUME 
(5) is set to minimum before you put the headphones on.
29. MICROPHONE CONNECTOR - This jack is used to a connect a microphone to the mixer. Con-
nect you microphone via 1/4 inch (6.3mm) jack. The signal volume will be controlled by the  MIC LEVEL 
(13). The bass and treble levels can also be adjusted by the built-in MICROPHONE EQ (13).

Due to fog residue, smoke, and dust, cleaning the mixer should be carried out periodically to residue 
build up.  
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-D6™                                Cross Fader Replacement
©American Audio®   -   www.americanaudio.us   -   Q-D6™ Instruction Manual Page 14
The crossfader is “Hot Swapable” 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.   Disconnect the mixers main power supply
2.   Using a Phillips screw driver, unscrew the two stainless steel retaining screws that hold the    
  crossfader in place.
3.   Gently remove the crossfader from its seated position. You may need to wiggle the crossfader    
  slightly to remove it.
4.   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 only fit one way, so don’t worry about the connec-   
  tors orientation.
5.   Connect the new crossfader to the ribbon cable and replace in reverse order.
