FADER “Q” START CONTROL: This feature is used in conjunction with American Audio® mixers that feature “Fader 
Q-Start”  control.  Connect  your  SDJ-1  as  described  in  the  set-up  section  of  this  manual.  After  set  up  is  completed 
load SDs into both players. By moving the mixer’s crossfader from left to right you can start and pause the SDJ-1™ 
playback functions. For Example, if the mixer’s crossfader is all the way to the left (player one is playing and player two 
is in cue or pause mode), and you move the fader at least 20% to the right, player two (2) will begin to play and player 
one  (1)  will  return  to  cue  mode.  When  the  crossfader  is  to  the  right,  and  you  move  it  20%  to  the  left,  player  one  (1) 
will begin to play and player two (2) will return to its’ cue point. You can create great effects similar to scratching with 
this feature. After storing cue points on each side of the SD player, different  songs or loops may quickly be recalled 
by  moving  the  mixer  crossfader  back  and  forth.  New  cue  points  can  be  easily  selected  on  the  SDJ-1™  player (see 
setting cue points page 16). “Q” Start control is easy to use and mastering this feature will help you create amazing 
effects with your music.

1. Checking the Contents      
 Be sure your SDJ-1™ was shipped with the following:          
 1)  SDJ-1™ Controller         2)  Operating Instructions (This Booklet)
     3)  Two (2) "Q-Start" 1/8” mini plug.      4)  Two (2) Sets of Stereo RCA Cables   
 5)  Warranty card.
2. Installing the Units 
 1)   Place your unit on a flat surface or mount it in a secure rack mount case.
  2)   Be sure the player is mounted in a well ventilated area where it will not be exposed to direct   
      sunlight, high temperatures, or high humidity.
 3)   Try to place the unit as far as possible from TVs and tuners, as the unit may cause undesir- 
       able interference.
3. Connections
 1)   Be sure main power is connected last to prevent any electrical damage.
  2) AUDIO CONNECTIONS: Use the included RCA cable to connect the SDJ-1™ outputs to 
       the line inputs of a mixer. Never connect this player's output to a mixers "phono" inputs. 
   3) CONTROL JACK CONNECTIONS: Use the supplied 1/8” mono mini plug cable to connect   
      your SDJ-1™ to a mini jack connection (A or B) on a compatible American Audio® or    
    American DJ® “Fader Q Start” mixer. (This will enable the Fader “Q” Start function - See “Q”   
      start control page 7).
CAUTION:
• Be sure to use the supplied mono 1/8" control cables. Using other types of cable may result 
 in unit damage
• To avoid sever damage to the unit, be sure the power is off when making connections to 
 the unit.

 gENErAL FUNCTIONS  AND CONTrOLS 
A. SD PLAYER  (FIgURE 1)
1. SEARCH  MODE  BUTTON  - Press  this  button  to  toggle  between  fast  search  (LED  lit)  and  slow 
search (LED off). The fast search will automatically turn off if the jog Wheel (20) is not used for more 
then 15 seconds. 
  - When  in  PLAY  mode,  you  can  use  the jog  Wheel  (20)  to  search  fast,  backward  or  forward 
through the current track. If in PLAY mode and the SEARCH mode is not activated the JOG WHEEL 
will act as a PITCH BEND.
  - When in PAUSE mode, you can use the jog Wheel (20) to search, backward or forward through 
the current track. If the SEARCH button is activated you can search fast through the track, if the but-
ton is not activated you can search frame by frame or a slow search.
2. SgL/CTN - This function allows you to choose between single track play or continuous track play 
(all tracks in order). This function also operates in FLIP  FLOP mode. See page 20 for FLIP FLOP. Hold 
this  button  down  for  1  second  to  toggle  the  Auto  Cue  function  on  and  off.  See  page  15  for  AUTO 
CUE.
3.  LCD  DISPLAY  - This  high  quality  LCD  display  indicates  all  the  functions,  as  they  are  occurring. 
The display ICONS will be explained on page 13.
4.  TEMPO  LOCK  FUNCTION  -  This  button  activates  and  deactivates  the  TEMPO  LOCK  function. 
This  function  allows  you  to  use  the pitch  SliDer  (5)  to  speed  up  or  slow  down  playback  speed
