FRONT PANEL FEATURES  
1. Open/Close: Press to load or eject the disc. The tray will not open if a disc is in play. The tray  
door will automatic close in 30 seconds if left open. This is to protect the tray from accidental  
damage while open  
2. Single: toggles the unit to play back just one track at a time (single) or play continuously through  
all tracks and then start over repeating the CD infinitely (continuous).  
3. Time: switches the time modes on the display between elapsed playing time, remaining time on  
the track, and remaining time on the total CD. When toggled to remaining time total the total  
number of remaining tracks will also show.  
4. LCD DISPLAY - Indicates all the functions, as they are occurring, with the CD.  
5. Track Buttons: These buttons are used to select the track to be played.  
6. Search Button: Pressing this button allows you to use the wheel and rapidly scan the music to  
find a cue point. The search function automatically shuts off after 8 seconds of non-use or you  
may toggle it off.  
7. Cue: Returns and pauses the music at the last set cue point. The cue point is where the music  
will begin when play is pressed. The cue point is set as the initial start point on a track or can be  
moved when play is started at a different point. For instance if the music is paused then play is  
pressed a new cue point is set. You can easily edit the cue point by turning the wheel during  
pause. As you rotate the wheel the music will sound. By stopping the wheel and pressing play a  
new point is set. Alternately pressing the PLAY button and the CUE button allows the CD to be  
played from the same position any number of times.

8. Play/Pause: Starts the music from the cue point or pauses it while in play. By pressing play after  
pause a new cue point will be set  
9. Jog Wheel:  
Cue Function: As explained under “CUE”, when the music is paused and you rotate the wheel,  
music will sound. By pressing play a new cue point is set.  
Search Function: As explained under “SEARCH BUTTON”, when search is press and you rotate  
the wheel, the music will rapidly scan the music to find a cue point.  
Pitch Bend Function: allows the user to temporarily change the speed of the music to align  
beats. When the beats of the music of the CD you wish to match is fast compared to the tempo of  
the other music rotate the jog wheel counter clockwise (to the left). When the CD is behind rotate  
the jog wheel clockwise (to the right). The pitch changes temporarily while the jog wheel is rotated.  
The faster you rotate the wheel the more pitch is changed. Releasing the wheel results in a  
return to the original pitch.  
10.Pitch Range: actives the pitch slider and adjusts the amount of control the pitch slider has on the  
overall speed of music. Tapping the pitch will toggle slider between 8% and 16% pitch ranges.  
Holding the pitch for 3 seconds will deactivate the pitch control.  
11.Pitch Range LEDs: indicate current pitch range. When both LEDs are off the pitch slider is not  
active  
12.Pitch Slider: By moving the slider in the (+) direction the speed of the music permanently speeds  
up. By moving the slider in the (-) direction the speed of the music permanently slows down. To  
match the speeds of two CDs you can adjust the pitch. When the tempo of the music of the CD  
you wish to match is slow compared to the tempo of the other music, move the slider to the (+)  
side and match the speed. When faster, move the pitch slider to the (-) side. By making this  
adjustment the speeds will be matched though the beats may not yet be aligned.  
13.CD Drawer – Place your CDs you wish to play in here. This unit is designed to play commercially  
available CD and properly burned and finalized CDR and CDRW formats. Due to variances on  
the specification of certain CD burners and CDs some discs home made CDs may not play  
properly.  
14.Power Switch- Turn on and turn off the machine with this button. The unit should always be shut  
down with this button first before any external power is removed.

DESCRIPTION OF THE PLAY/PAUSE AND CUE OPERATIONS  
PLAY and CUE  
Pressing the “PLAY/PAUSE” button starts the disc. Pressing the “CUE” button will reset the disc to the last place  
where the disc was started. This is called the cue point. By alternately pressing the “PLAY/PAUSE” button and the  
“CUE” button, the disc may be returned and played from the cue point any number of times. This function is called back  
cue.  
PLAY, PAUSE and CUE  
When Play is paused and then started again, the return position for the back cue will be updated as the new cue  
point  
EDITING CUE POINT  
When the jog wheel is turned while a cue point is set, a new cue point can be located. The CD player will  
repeatedly play small parts of the CD as you move it to the desired position. By pressing “PLAY/PAUSE” then “CUE” you  
can confirm that this new cue point is desirable.

MATCHING THE BEATS PER MINUTE (BPM)  
Match the tempo by monitoring the music of both PLAYER 1 and PLAYER 2 by ear and adjusting the pitch.  
When the tempo of the music of the selected CD player is slow compared to the tempo of the other player, move the  
slider to the “+” side and match the tempo. When faster, move the pitch slider to the “-“ side. The following description is  
for the case of matching the pitch of PLAYER 2 to the pitch of the music being played on PLAYER 1.  
Press PLAY/PAUSE to start PLAYER 1  
PLAYER 1 is playing  
Press PLAY/PAUSE to start PLAYER 2  
Both CD players are playing discs.  
Listen to PLAYER 2 in your headphones  
When PLAYER 2 is fast  
compared to PLAYER 1  
slow down PLAYER 2  
When PLAYER 2 is slow  
compared to PLAYER 1  
speed up PLAYER 2  
MATCHING BEATS USING PITCH BEND  
If you find the BPM’s (Beats Per Minute or Tempos) are the same, however, the drumbeats are not matched you  
will need to temporarily change the pitch. This description is for the case of matching the beat of PLAYER 2 to the beat of  
the music being played on PLAYER 1. (This procedure can be done on either PLAYER).  
After matching the BPM’s adjust the pitch temporarily as follows:  
When PLAYER 2 is behind rotate the jog wheel  
clockwise to bend pitch faster  
When PLAYER 2 is ahead rotate the jog wheel counter  
clockwise to bend pitch slower.  
The pitch changes automatically while the jog wheel is rotated. The faster you rotate the wheel the more you change.  
Releasing the wheel results in a return to the original pitch. (So the BPM’s are once again the same)
