 MAIN FEATURES
(a)    60  SECOND  TRANSPORT  PROTECTION:  The  CD  transport  tray  will  automatically  close  if  left  open  for  more  than  60  sec-
onds. If a CD is left in the tray it will immediately cue. 
 
(b)    JOG  WHEEL  PITCH  BEND:  During  normal  playback,  the  jog  wheel  acts  as  a  momentary  pitch  bend.  Turing  the  wheel  in  a 
clockwise direction will increase the speed and turning the wheel in a counter-clockwise direction will decrease the speed. 
 
(c)  FADER “Q” START CONTROL: This feature is used in conjunction with American Audio
® mixers that also feature “Fader Q 
Start” control. Connect your DCD-PRO310 as described in the set-up section of this manual. After set-up is completed, insert 
CD's in to both drives. By moving the mixer’s crossfader from left to right you can start and pause your DCD-PRO310 playback 
functions.  For  Example,  if  your  mixer’s  crossfader  is  all  the  way  to  the  left  player  one  is  playing,  player  two  is  in  cue  or  pause 
mode. If slice the fader at least 20% to the right, player one will continue to play and player two will begin to play, mixing both 
sides together. When the crossfader is slid all the way to the right, player two will is playing, and player one will go into cue or 
pause mode. You can create great effects similar to scratching with this feature.  “Q” Start control is easy to use and mastering 
this feature will help you create amazing effects with your music. 
(d)   FLIP-FLOP™: For FLIP-FLOP™ results you must use both disc drives. Connect your DCD-PRO310 as described in the set-
up section of this manual. This feature will start the next player side once one player side has ended. For example, if disc drive 
one is playing a disc and it ends, disc drive 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 18-19.

 GENERAL FUNCTIONS AND CONTROLS - REMOTE UNIT
©American Audio®   -   www.americanaudio.us   -   DCD-PRO310™ Instruction Manual Page 8
REMOTE CONTROL - FACE (FIGURE 3)
1. JOG WHEEL -  The jog wheel serves two functions depending on the current operating mode:   
  A.  The jog wheel will act as a slow frame search control when the unit is in pause or cue mode  
    allowing 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  
    clockwise will increase the pitch percentage up to 16%, and turning the wheel in the coun- 
    terclockwise direction will decrease the pitch percentage up to -16%. The pitch bend will be  
    determined on how fast you turn the wheel.
2.  LIQUID CRYSTAL DISPLAY (LCD) -  This high quality LCD Indicates all the functions (play, pause, 
cue,  etc..,),  as  they  occur.  This  display  is  viewable  at  several  comfortable  angles  as  described  on 
page 6. The LCD icons will be described in the next section.
3. PITCH SLIDER - This slider is used to adjust the playback pitch percentage when the PITCH (13)

function is activated. The slider is a set adjustment and will remain set until the pitch slider is moved 
or the 
PITCH (9) function has been turned off. The maximum pitch range of the slider is +/-12%. This 
adjustment  can  be  made  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 will also have a +2% 
pitch. The amount of pitch being applied will be displayed in the  LCD (2). 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. 
4. LOOP IN BUTTON -  “CUE ON THE FLY” -  This function allows you to set a CUE POINT (see CUE 
POINT page 18) without music interruption (“on the fly”). This button also sets the starting point of a  
loop (see LOOP).
5.  REPEAT  BUTTON  -  When  the  player  is  in  SINGLE  mode  and  this  button  is  pushed  the  song  will 
rep
eat  until the button is pressed again. The Red LED above the button  will glow when this function 
is act
ive.
6. +10 TRACK SKIP -  This button allows you to skip ahead by 10 tracks. Example:  if you are at Track 
#1, pressing this button will skip you to Track #11, press the button again, it will skip to Track #21. If 
there are not that many tracks, it will go back to Track #1. 
7.  SGL/CTN  -  This  button  allows  the  unit's  play  mode  to  change  between  Single  and  Continuous.
