STARTING PLAY OPTIONS
Play can be started any 1 of 3 ways
1. Pressing the “PLAY/PAUSE” button
2. Pressing the “STUTTER” button as explained in the STUTTER SECTION
3. When the cue button is pressed a second time, it will temporarily play a section and will
stop it when the button is released. (to check a cue point)
SETTING OR EDITING A CUE/START POINT
The purpose of a cue point is to set a defined position in the music at which you would like to start playing the song. There
are 4 methods by which a cue point can be set.
1.When a track is initially selected, a cue point
is automatically set after the elimination of
dead space. 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”.
Note: You can also preview a “CUE POINT” by holding down the “CUE” button a
second time. This will play the track from the cue point until you release it.
2.The search and/or jog wheel is used
to set a different start point, also
referred to as editing. When the inner
search dial is turned while the unit is
paused, 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 this new cue point is desirable.
3.Pressing the “PLAY/PAUSE” button starts the disc. Pressing the “PLAY/PAUSE” button when the disc is playing
then pressing it again sets a new cue point. You can edit this point with the jog wheel after you have paused as
described in the previous method. Pressing the “CUE” button the first time instead of the “PLAY/PAUSE” button
again will reset the disc to the previous cued position.
4.The “LOOP IN” button is depressed during play for any reason as explained in LOOPING and STUTTERING.

USING THE LOOPING FEATURES
These feature are for seamlessly looping certain areas of the CD.
LOOP
IN LOOP OUT
RELOOP
STUTTER
A loop is any area of a CD that you choose to repeat with
no breaks.
There are 3 buttons associated with the loop feature.
LOOP IN
The “LOOP IN” is where you wish for the loop to actually start. You will notice the “LOOP IN” LED will be lit every time you
put in a new cd and select a new track. This means that the initial “CUE” point of the CD is also the default “LOOP IN”
point. If you wish to set a new “LOOP IN” point, just press the “LOOP IN” button while the CD is playing when it reaches
the desired point. By default this also becomes the new “CUE” point.
NOTE: The CD Player will always remember a new set point as the “LOOP IN” point until you
actually set a new “LOOP IN” point , erase the loop, or put in a new CD. If you set a “LOOP IN”
point and then do a track search prior to the point position, setting a new auto-cue point, the
LOOP IN LED will turn off. This indicates that the CD player has stored a “LOOP IN” point but
the point is not accessible until the CD players plays through the “LOOP IN” point.
The ”CUE” button will return you to the start position until you play through the “LOOP IN”
point. Then it will return to “LOOP IN”
LOOP OUT
The “LOOP OUT” determines the end point for a loop. The first time you press this button while a CD is in play mode, the
“LOOP OUT” LED will turn onand flash while the song automatically returns to the “LOOP IN” point with no breaks and
continues to play. When the song reaches the “LOOP OUT” point again it returns to the “LOOP IN” point and continues
to repeat this action. You will notice the “LOOP IN” LED will also be flashing during loop action. To release or end the
LOOP press the “LOOP OUT” button a second time and play will continue forward when the song passes the previously
set “LOOP OUT” point. The “LOOP OUT” and “LOOP IN” LEDs will also be lit solid indicating that these “LOOP” points
are now in memory for “RELOOP” purposes.
Note: The “LOOP OUT” point will be erased if “LOOP IN” is pressed or a new “CUE”
point is set after the “LOOP OUT” point. This is important because without this point
“RELOOP” will not be possible.

CDN-34
MOVING LOOP POINTS
The “LOOP IN” point can be moved while a loop is playing just by pressing the “LOOP IN” button at the new desired point.
The next time “LOOP OUT” is reached the CD will return to this new “LOOP IN” point. If you should accidentally set a new
“LOOP IN” point at the same place as your “LOOP OUT” point the “LOOP OUT” point will be erased and play will continue.
Note: If for any reason you should press pause then play to restart a track in between these loop
points, setting a new cue point, this will also set a new “LOOP IN” point.
The “LOOP OUT” point can also be moved while a loop is playing just by first pressing this button to release the old
“LOOP OUT” point and pressing it again at the new desired point.
RELOOP
The “RELOOP/STUTTER” button performs 2 different functions depending on your state of play. The Reloop function is
possible only if “LOOP” points have been previously set and the CD is playing beyond the “LOOP OUT” point.
The “RELOOP” button automatically causes a loop to be played again until it is released with the “LOOP OUT” button.
The LEDs will flash during the loop and then become solid following the loop.
The second function of this button is described in the section called “STUTTERING FUN”

CDN-34
PRE-PROGRAMMING AND EDITING A LOOP
You can pre-program your loop and also edit it.
LOOP IN PRE-PROGRAM
To pre-program your “LOOP IN” point either play your song or search for the desired “LOOP IN” point using
the search and jog wheels. When you get to the desired point press “LOOP IN”. If you wish to edit this point
turn the jog wheel until you find the desired point. When you press play the CD will begin play from the new
“LOOP IN” point. This also is the temporarynew “CUE” point. If you then hit play to listen to the point and
cue to go back you can continue to edit with the jog wheel.
LOOP OUT PRE-PROGRAM
To pre-program your “LOOP OUT” point play your song until you get to the desired “LOOP OUT” point and
press “LOOP OUT”. To rapidly advance over a long distance you can use the search wheel with no center
cue- jog. DO NOT USE THE TRACK BUTTONS**. If the CD player is presently in play mode, the
song will return to the “LOOP IN” point and continue playing the LOOP.
If you wish to precisely set the “LOOP OUT” point while searching;
a. press “PAUSE” once only before you reach the desired point, if you are currently in play
b. turn the jog wheel until you find the desired point
c. hit “LOOP OUT”
REVIEW YOUR LOOP
To review, press “RELOOP” only and the CD will begin playing the LOOP from the “LOOP IN” point so you
may listen to the entire LOOP. DO NOT PRESS PLAY OR YOU WILL SET A NEW “CUE” AND
“LOOP IN” POINT AND ERASE THE “LOOP OUT” POINT! If you wish to advance quickly through
a long loop use the search wheel only.
If you wish to edit this point again;
a. press “LOOP OUT” to release the loop
b. repeat the above steps
To review your loop while the CD is already playing press “CUE”. This returns the CD to the
“LOOP IN” point, then press play.
** Pressing the track buttons puts the CD player into an auto-cue mode.
Multiple tracks are often found for single songs on remix service CDs.
The track select mode automatically sets new cue points and would set a
new “LOOP IN” point if set after the original “LOOP IN” point.
- The Leader in DJ Technology
©1999 Industries 14 http://www.numark.com

CDN-34
PLAYING YOUR LOOP
To return to the beginning of the song and play after you are happy with the loop:
a. Press “PAUSE” to stop the play action of the CD or “CUE” to return to the “LOOP IN” point
b. Track backwards until you reach the beginning of the song. (Remix CD’s often contain multiple track
numbers for the same song.)
c. Auto-cue to the beginning of the track will then occur. Once this occurs your cue button will return you
to this point until you pass over the “LOOP IN” point. Then “LOOP IN” will be the new “CUE” point.
d. The “LOOP OUT” LED will be flashing indicating a preset loop is ahead and will be played when reached
e. When the “LOOP IN” point is reached both “LOOP IN” and “LOOP OUT” LEDs should flash
f. The LOOP should occur as preset by you until you release it with the “LOOP OUT” button
g. Both “LOOP IN” and “LOOP OUT” LEDs should then go solid again indicating the possibility of
RELOOP
NOTE: If you should decide that you do not want to automatically play a preset loop after you start
a song, just press “LOOP OUT” anytime before you actually reach the “LOOP OUT” point and the
“LOOP OUT” LED will remain solid. (You can press it again before the “LOOP IN” point if you
change you mind.) The “LOOP IN” LED will come on solid when this point is reached indicating the
possibility of RELOOP. This will allow you to use the selection for reloop purposes. However, until
you pass the “LOOP OUT” point the “RELOOP/STUTTER” button only acts as a STUTTER
function as explained in STUTTERING FFFUN.
If you turned off your “LOOP OUT” while practicing your loop remember to turn it on again before reaching the
“LOOP IN” point.
ERASING YOUR LOOP
To erase a preset loop either;
a. Open and close the door
b. Press the program button twice
c. Select a track, a new “CUE” point, or new “LOOP IN” point beyond the “LOOP OUT” point
d. Press “LOOP IN” prior to the old point to set a new loop
DESCRIPTION OF LED DISPLAYS
1) LOOP IN on /LOOP OUT off : This
means that there is a LOOP IN point available
for looping and stuttering, but no LOOP OUT
point is set yet.
2) LOOP IN flashing /LOOP OUT
flashing: This indicates that the CD player is
actively looping from LOOP IN to LOOP OUT.
3) LOOP IN on /LOOP OUT on : This
indicates that the LOOP IN and LOOP OUT
points are set and a RELOOP will return to the
LOOP IN to play the loop.
4) LOOP IN off /LOOP OUT off : This indicates that
a) there is a LOOP IN point stored into memory, but this
looping function and this STUTTER point are
disabled until the music plays through the point.
b) there is no LOOP OUT point set yet.
5) LOOP IN off /LOOP OUT on : A future loop has been
stored into memory. This loop will be inactive until either LOOP
OUT is presses prior to the CD playing through the LOOP IN
point or RELOOP is pressed after the LOOP IN point.
6) LOOP IN off /LOOP OUT flashing : An active loop is
stored into memory and will automatically play after the music
plays through the LOOP IN point.

DESCRIPTION OF STUTTERING FFFFUN........
This function allows music to be replayed from the last set cue point seamlessly.
Carefully read all of the following conditions to fully understand this button’s operation. Don’t forget
this button serves two functions depending upon the CD player’s state of play.
1. If the CD is paused either at the beginning of a track or
at some other “CUE” point the “STUTTER/RELOOP”
can start play of the song and actually seamlessly
restart every time the button is pressed.
2. If the song is already playing and no additional cue or
loop in points have been set then the CD will return to
the place where you originally started playing and
seamlessly start playing again. If this was on a beat
this would be a quick way to seamlessly extend a mix.
3. If another “CUE” or “LOOP IN” point has been set, but
you have not reached this point yet, the song will
return to the start position and seamlessly restart
playing.
4. If a “LOOP IN” point but no “LOOP OUT” point has
been set and you have passed this point, then the
song will return to the “LOOP IN” point and start
playing. The reason for this is that every time you set
a “LOOP IN” point you are also resetting the “CUE”
point.
5. If a “LOOP IN” point and “LOOP OUT” point have been
set and the CD is in the middle of playing a loop then
the “STUTTER/RELOOP” button will create a stutter
back to the “LOOP IN” point and continue the set
loop until the “LOOP OUT” button is pressed to
release the loop.
Again it is important to remember that
“STUTTER” and “RELOOP” are the same button.
6. If a “LOOP IN” point and “LOOP OUT” point have been set and the CD is
finished playing a loop then the “STUTTER/RELOOP” will return to the
“LOOP IN” and continue to RELOOP until the “LOOP OUT” is pressed.
7. If a new ”LOOP IN” point is set after the last “LOOP OUT” point then this
can be a new “STUTTER” point.
Simply put, you can Stutter on either your initial cue point or a set “LOOP IN” point, whichever is
immediately prior to your current play position.
(PRACTICE ALL OF THIS BEFORE SHOWING YOUR SKILLS TO THE AUDIENCE !)

DESCRIPTION OF ANTI-SHOCK BUFFER MEMORY
This CD Player is equipped with a total of 24 Seconds of RAM Buffer memory.
12 Seconds of this is used for the Anti-Shock Buffer and the other 12 are used for various
other seamless loop, stutter, and instant start functions. Anti-shock is to allows the unit to be
bumped around hard for 6 seconds per side and not stop. When the CD is first placed in
the tray and a track is selected, the CD player quickly reads the beginning of the track and
stores it into a buffer memory, the same way a computer stores information in RAM. This
initial operation takes about 5 seconds. As you play the track, the CD Player continues to
read ahead of the music and stores this information in the buffer. If the unit is bumped the
CD Player will continue to play from this buffer until the unit recovers and can start filling the
buffer again. The buffer should be long enough to allow recovery from most situations,
however, continual shocks can erase the buffer memory. If the unit should ever run out of
buffer and still be receiving shocks, then the last 2 seconds will repeat until continuation can
occur. The music never stops.
NOTE: The CD player can not store buffer information during the setting of a cue point with the jog
wheel. If you start a CD without giving it an opportunity to load buffer it will still start instantly and load buffer
slowly. It will recover 1 second of buffer for every 6 seconds of music played at 0% pitch.

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. With the
CDN-34 you also have the option of using the BPM display as explained below. 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 and
look at the BPM display information
When PLAYER 2 is slow compared to
PLAYER 1
speed up PLAYER 2
When PLAYER 2 is fast
compared to PLAYER 1
slow down PLAYER 2
USING THE BPM DISPLAY FEATURE
Press the BPM button to select the BPM feature
on the display on the side of the
CD player that you wish to set.
Tap the Counter button to the beat of the music.
You will see the BPM number appear in the display.
The more times you tap the more accurate your number
will be. When you adjust the pitch slider the display
number will change by an equal percentage .

BEAT MATCHING USING PITCH BEND
Beat matching is necessary when the BPM’s are the same of both songs, however, the drum beats are not hitting at the
same time.
This is a description of the procedure for matching the beat of PLAYER 1 and PLAYER 2 using the PITCH BEND button.
(This procedure can be done on either PLAYER).
After matching the BPM’s adjust the pitch
temporarily as follows:
When PLAYER 2 is ahead press the --
or rotate the jog wheel counter clockwise
or
When PLAYER 2 is behind press the +
or rotate the jog wheel clockwise
or
The pitch changes automatically while the + or -- button is being pressed or the jog wheel is rotated. The faster
you rotate the wheel the more you change. Releasing the button or wheel results in a return to the original pitch. (So the
BPM’s are once again the same.)
