 MAIN FEATURES
(a)  FADER “Q” START CONTROL: This feature is used in conjunction with American Audio® mixers that also 
feature  “Fader  Q  Start”  control.  For  best  results  use  this  feature  with  two  Pro-DJ  players.  Connect  your  Pro-
DJ’s as described in the set-up section of this manual. After set-up is completed load your unit's. By moving 
the mixer’s crossfader from left to right you can start and pause your Pro-DJ playback functions. For Example, 
when  using  two  Pro-DJ  units  and  a  Fader  “Q”  Start  mixer,  if  your  mixer’s  crossfader  is  all  the  way  to  the  left 
(player one is playing, player two is in cue or pause mode), and you move the fader at least 20% to the right, 
player two will begin to play and player one will return to cue mode. When the crossfader is to the right, and you 
move it 20% to the left, player one (will begin to play and player two will return to its’ cue point. You can cre
-
ate great effects similar to scratching with this feature. After storing cue points on each side of the CD player, 
different songs or samples may quickly be recalled by moving the mixer crossfader back and forth. New cue 
points can be easily selected on the Pro-DJ player  (see setting cue points page 17). “Q” Start control is easy 
to  use  and  mastering  this  feature  will  help  you  create  amazing  effects  with  your  music.  Note:  For  proper  “Q” 
Start operation be sure your mixers “Hamster” setting are set to 1/2 (Normal Setting).
(b)  BOP EFFECT: The Bop Effect button serves two features. First, it is a stutter effect, creating a sound similar 
to a sampler. Second, it will return to the last Cue point in memory instantly. This will allow you to  create great 
effects. To create the BOP Effect, see BOP Effect on page 21.
(c)  FLIP-FLOP:  This  feature  is  used  in  conjunction  with  American  Audio®  mixers  that  also  feature  Fader  “Q” 
Start.  For  FLIP-FLOP  results  you  must  use  two  Pro-DJ  players.  Connect  your  Pro-DJ’s  as  described  in  the 
set-up section of this manual. This feature will start the next player once one player has ended. For example, if 
player one is playing a disc and it ends, player two will instantly begin to play. You may set FLIP-FLOP to play 
track to track or disc to disc. For more information on this feature, see FLIP-FLOP™ on page 22.
(d)  60  SECOND  TRANSPORT  PROTECTION:  The  CD  transport  tray  will  automatically  close  if  left  open  for 
more than 60 seconds. If a CD is left in the tray it will immediately cue. 
(e)  SLEEP  MODE:  The  Pro-DJ’s  laser  and  pick-up  assembly  will  power  down  after  15  minutes  of  inactivity 
(when  in  pause  or  cue  mode).  This  will  lengthen  the  life  of  your  motor  drive  and  laser.  To  initialize  the  player, 
just press the cue or play buttons.
(f)  MEMORY  BACKUP:  The  Pro-DJ  has  a  five  year  memory  back-up,  that  will  save  your  setting  in  case  the 
power supply is accidentally disconnected. Pro-DJ will automatically remember your last setting (repeat, SGL, 
CTN)  even  if  you  disconnect  your  main  power..  The  Pro-DJ  will  store  your  cue  points  in  memory  if  you  acci
-
dentally  open  transport  tray  or  shut  off  the  power.  Note:  Memory  cues  are  erased  automatically  when  a  new 
CD is played, or by holding memory button down for 3-4 seconds.

ing you to set a specific cue point or find a particular starting point. 
B.  The inner wheel also works as a momentary pitch bend during playback. Turning the wheel clock-
wise  will  increase  the  pitch  percentage  up  to  12%,  and  turning  the  wheel  in  the  counterclockwise 
direction will decrease the pitch percentage up to -12%. The pitch bend will be determined on how 
fast you turn the wheel.

with or without a CD in the drive. The pitch adjustment will remain even if a disc has been removed, 
and  will  reflect  on  any  other  disc  loaded  into  the  unit.  That  is  to  say,  if  you  set  a  +2%  pitch  on  one 
disc,  remove  that  disc  and  insert  another,  that  disc  too  will  have  a  +2%  pitch.  The  amount  of  pitch 
being applied will be displayed in the  LCD (5). Use this slider to match the BPM’s of this unit to that 
of another music source. By changing the pitch of one disc with respect to the other in this way, the 
beats can be matched.

19. SGL/CTN -  This button allows the unit's play mode to change between Single and Continuous. 
In single mode the unit will play a single track and return to cue mode. In  continuous mode the unit 
continues  to  play  track  by  track  and  returns  to  cue  mode  after  all  tracks  have  played.  This  function 
also  operates  in 
PROGRAM and  FLIP  FLOP modes.  In  program  mode  the  continuous  function  will 
play  all  tracks  in  a  program,  than  return  to  cue  mode  on  the  first  track  in  the  program.  When  using 
two  units  in  Flip-Flop  mode,  each  unit  may  be  set  up  to  run  in  either  single  or  continuous.  In  single
