1. OPEN/CLOSE - (Disc Tray Open/Close)- Press to load or eject the disc. Each press will open or close the disc  
tray on the transport. NOTE: Tray will not open unless the disc has been paused.  
2. OUT BUTTON - Used to set the ending point when looping. When the OUT BUTTON is pressed, the player will  
play the loop continuously. To exit the loop, press the OUT BUTTON again.  
3. IN BUTTON - This button sets the loop start point  
4. SHUTTLE WHEEL - (OUTER RING) This wheel has 6 forward and 6 reverse speed positions for searching  
through songs. The more you turn the wheel in either direction the faster you search through the music.  
5. JOG WHEEL - (INNER RING) This jog wheel serves two functions depending on the mode you are working in.  
a. The jog wheel will act as a slow frame search control when the CD is not playing but either paused  
or set to a cue point. To set a new frame cue point, spin the wheel then press PLAY (9) when you  
have determined the proper position. Press CUE (7) to return to the “CUE POINT”.  
b. It also works as a pitch bend, when you turn clockwise the pitch will rise to 16%, and when you turn  
counterclockwise it will fall to -16%. The pitch bend is determined on how fast you turn the wheel.  
6.  
TRACK BUTTON - This button is used to select a BACK SKIP track to be played.  
7. CUE - Pressing the CUE BUTTON during play provides a return to the position at which play was started. If  
PAUSE is used before CUE or a CUE POINT was set, that will become the cue point. Alternately pressing the  
PLAY button and the CUE BUTTON allows the CD to be played from the same position any number of times.  
The CUE LED will light up from the time the Cue button is pressed until the CD has reset to the position at

Pitch percentage (%) can be changed by holding the PITCH BUTTON (18) and pushing the plus (+) BUTTON (14)  
to change the percentage (%) selection.  
12. RELOOP BUTTON - If a LOOP has been made, but the CD Player is not actively in LOOP mode, press the  
RELOOP BUTTON to reactivate the LOOP. RELOOP will appear in the LCD DISPLAY (13). To exit loop, press the

mode - This is not a malfunction.  
14. (+) & (-) PITCH BEND Button - When each of the two CD players is playing a CD, the pitch bend function allows  
the positioning of the bass beats to be matched after the pitch of each disc is matched. Either player can “catch up”  
or “fall back” to match the other player. The pitch will automatically rise when the (+) BUTTON is pressed (allowing  
“catch up”) and return to the original pitch when the button is released. The pitch will automatically drop when the (-)  
BUTTON is pressed (allowing “fall back”) and return to the original pitch when the button is released. By changing  
the pitch of one disc with respect to the other in this way the beats can be matched.

(a) SLEEP MODE PROTECTION: After 15 minutes in PAUSE or CUE Mode the CD drive mechanism will automatically go in to  
sleep mode. This function shuts down the laser pick-up diode extending the life of the unit. During sleep mode the LCD screen  
will flash repeatedly indicating sleep mode is activated - This is not a malfunction, to restart the drive simply press the Cue or  
Play/Pause Buttons  
(b) 60 SECOND TRANSPORT PROTECTION: Will automatically close transport if left open for more than 60 seconds to prevent  
someone from walking by and breaking the transport.  
(c) FLIP-FLOP: On the rear of the PRO DJ2 there is a control input jack, use a standard stereo mini plug to plug in one PRO DJ1  
to another, via the control jacks. Set both of the CD players to single play mode. Play Disc 1, Disc 2 will immediately begin to  
play when the track ends on disk 1. Disc 1 will return to cue mode and will begin to play at the end of disc 2 track. This function  
will continue until the jacks are disconnected but may be overridden at any time through manual operation.  
(d) Memory Backup: This will automatically save your last setting (SGL, CTN) even if you unplug AC- current.  
(e) “Q” Start Control: This feature is used with American DJ “Q-Series” mixers featuring Fader Q Start. Connect a standard  
American DJ mini plugs, from CD1 output on CD player to the “A” player control input on the rear of mixer. Then connect the  
other mini plug from CD 2 output on CD player to the “B” player control input on the rear of mixer. By moving the mixer fader  
from left to right you can start and pause Disc1 and Disc 2 respectively. In other words, when the cross-fader of the mixer is to  
the left, and you move it 20% to the right, Disc 2 will begin to play. When the cross-fader is to the right, and you move it 20% to  
the left, Disc 1 will begin to play. 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 become a better DJ.

BASIC OPERATIONS (CONT.)  
14. PITCH BENDING  
The speed increases or decreases respectively when the (+) PITCH BEND BUTTON (14) or PITCH BEND  
(-) BUTTON (14) is pressed. The extent to which the speed changes is proportionate to the amount of time  
the button is pressed. For example, if the PITCH BEND (+) BUTTON (14) is held in continuously, the speed  
increases continuously.  
The pitch can be changed from range. See changing PITCH PERCENTAGE (17).  
The jog wheel will temporarily bend the pitch of the music if the song is already playing. Rotate the wheel  
clock-wise to speed up or counterclockwise to slow down. The speed that you rotate the inner JOG WHEEL  
determines the percentage (%) of the PITCH BEND.  
15. PROGRAM PLAY  
(1) Press the PROGRAM BUTTON (17) to make the unit enter the program mode in stop position. The  
PROGRAM INDICATOR (27)LED above the PROGRAM BUTTON (17) will light as well as the PROGRAM
