counter to reset and recalculate.

23. MARCHING BAR GRAPH – Tracks the beats and measure position of music.

24. INTERLOCK – Links both players for beat alignment.

CD PLAYER & REAR PANEL FEATURES

25. CD DRAWER – Place your CDs you wish to play in here. This unit is designed to play commercially
available CDs, MP3 CDs and properly burned and finalized CD-Rs. Due to variances on the
specification of certain CD burners and CDs, some homemade CDs may not play properly. We
recommend burning CDs at the minimum speed possible for the best performance.

26. EJECT – Pressing will open or close the disc tray on the transport.

27. POWER SWITCH – Turn the machine on and off with this button. The unit should always be shut
down with this button first before any external power is removed. Typically it is recommended that the
CD player is powered on before amplifiers and powered off after amplifiers.

28. IEC POWER PLUG CONNECTOR – Plug your supplied power cord in here.

29. CONTROL CABLE CONNECTOR – Plug in the 8-pin cable included in here to connect the remote
control and main CD unit together.

30. RCA AUDIO CONNECTORS – Connect your CD player to your mixer from this line level output.

31. REMOTE START CONNECTOR – Use this connector to plug into your fader start compatible mixer or
remote switch. This function is always active.

y To use this connector for fader start, connect the supplied fader start cable to a fader start

compatible mixer. Every time you move the crossfader on the mixer over to the side that the unit
is on, it will automatically start playing. When you move the fader away from that side, the unit
will stop. Moving the fader back to the unit side will start play again.

y Foot switches can also be attached to this jack for creative mixing techniques and can be found in

most music shops. Connector plugs are often 1/4” and an adapter to 1/8” will be needed for
connection. There are also two types of footswitches that will work with this connector. The first
is a typical, on/off pushbutton switch and are generally used for switching channels on guitar
amps. The second switch is a momentary footswitch and is usually used for keyboard sustain
pedals.

BASIC OPERATIONS

EJECT: Press to load or eject the disc. The drawer will automatically close to protect the
tray from accidental damage while open. (The tray will not open while a disc is playing.) To
program the automatic close time, hold down PROGRAM and press EJECT. The LCD will
indicate options of 30 seconds, 60 seconds, 120 seconds, and "no" for no auto-close. This

setting will be remembered at power down.

PLAY / STUTTER: Starts the music from either the first set Cue Point or the last point at

which it was paused. If the deck is paused, pressing PLAY / STUTTER will start playback
and set a new Cue Point. If the deck is playing, pressing PLAY / STUTTER will restart
playback from the last Cue Point, creating a “stutter” effect.

To adjust the speed at which playback starts hold down PROGRAM, press PLAY /
STUTTER, and rotate the JOG WHEEL until the desired seconds are shown on the LCD.
After this, you can toggle between a playback start time of "0" ("Start Up OFF") and the time
you just set ("Start Up ON") by holding down PROGRAM then pressing PLAY / STUTTER.
This setting will be remembered at power down.

PAUSE: Pauses playback. Pressing PLAY / STUTTER while the deck is paused sets a
new Cue Point. Holding down PAUSE while scratching or stuttering the music will stop the
music at the current position, allowing you to capture a Loop In or Cue Point.

To adjust the braking time – the speed at which playback stops – hold down PROGRAM,
press PAUSE, and rotate the JOG WHEEL until the desired seconds are shown on the LCD.
After this, you can toggle between a braking time of "0" ("Brake OFF") and the time you just
set ("Brake ON") by holding down PROGRAM then pressing PAUSE. This setting will be
remembered at power down.

CUE: Returns to and pauses the music at the last set Cue Point. The Cue Point is the last
place in which the track was paused and then PLAY / STUTTER was pressed. Pressing
and holding CUE will start playback from this point. The deck will return to the Cue Point
and pause once you release CUE.

You can edit the Cue Point by turning the JOG WHEEL. As you rotate
the JOG WHEEL, you will hear it "scrubbing" through the audio of the
track. Stop the JOG WHEEL and press PLAY / STUTTER to set the
new Cue Point and start playback from there.

The audio you hear while rotating the JOG WHEEL in Scratch Mode can
either be a smooth “scratch” sound ("TT CUEING") or a traditional
“stutter” sound ("NO TT CUEING"). To toggle between these modes, hold PROGRAM then
press CUE. This setting will be remembered at power down.

TIME: Switches the Time Mode on the LCD between elapsed playing time ("ELAPSED"),
remaining time on the track ("REMAIN"), and remaining time on the entire CD ("TOTAL
REMAIN"). This setting will be remembered at power down.

SINGLE: Toggles between Single Play Mode (playback will stop when a track ends) and
Continuous Play Mode (when a track ends, the next track will play and the CD itself will
restart when the last track has played). This setting will be remembered at power down.

TRACK SELECTION: Rotate the TRACK SELECT / SEARCH knob to find the desired
track. To skip through every tenth track, hold down the knob while rotating it.

SEARCH: Pressing the TRACK SELECT / SEARCH knob puts the JOG
WHEEL in Search Mode, which will remain active while the JOG
WHEEL is being moved and for 8 seconds after. In Search Mode,
rotating the JOG WHEEL will let you search rapidly through the track.
(There are two search speeds depending on how quickly you rotate the
JOG WHEEL.)

8

SETTING CUE POINTS

PLAY and CUE: Pressing PLAY / STUTTER starts playback. Pressing CUE will return the track to the last
place playback was started. This is called the Cue Point. By alternately pressing PLAY / STUTTER and
CUE, the track may be returned and played from the Cue Point any number of times. This is called "back
cueing."

PLAY, PAUSE, and CUE: Pressing PLAY / STUTTER to start playback, pressing PAUSE, and pressing
PLAY / STUTTER again will set a new Cue Point. Pressing CUE will return the track to where it was last
paused, which will become the new Cue Point.

EDITING CUE POINTS: When the track is paused, you can rotate the JOG WHEEL to locate the position for
a new Cue Point. By pressing PLAY / STUTTER from this paused position, you will set the new Cue Point.

ADJUSTING PITCH

PITCH RANGE: Activates or deactivates the PITCH SLIDER and adjusts the amount
of control it has on the speed of deck. You can select 6, 12, 25, or 100% as the range
of the PITCH SLIDER by holding down PITCH RANGE and pressing "–/+" to cycle
through the options (shown in the LCD's PITCH indicator). This setting will be
remembered at power down.

PITCH SLIDER: By moving the PITCH SLIDER down, the pitch and tempo of the
music will increase. Move it up to decrease it. If the selected Pitch Range is 100%,
the PITCH SLIDER's extreme positions can play the track at twice its original speed or
reduce its playback speed to zero.

To match the tempos of two decks, you can either monitor the music of both decks by
ear or use the automatic BPM indicators and shift the PITCH SLIDER so the BPMs
match. (You may still need to align the beats of the two tracks after the tempos are
matched.) See MATCHING BPMs for more information.

9

PITCH BEND and JOG WHEEL: These controls temporarily change the tempo of the
music so the beats of the two decks can be aligned. The faster you rotate the JOG
WHEEL or the longer you hold the "–/+" buttons, the greater the change in tempo.
When the button or wheel is released, the deck will return to its usual tempo.

MATCHING BPMs (BEATS PER MINUTE)

You can match the tempos of the two decks either by ear or by looking at the BPM indicator on the LCD and
adjusting a deck's pitch with the PITCH SLIDER until they match. If the deck whose tempo you want to
match is faster, increase the tempo with the PITCH SLIDER on the opposite deck. If the deck whose tempo
you want to match is slower, decrease the tempo with the PITCH SLIDER on the opposite deck. (You may
still need to align the beats of the two tracks after the tempos are matched.)

The following example describes how to match the pitch of Deck B to the pitch of Deck A.

MATCHING BEATS WITH PITCH BEND

Even when the BPMs (beats per minute) are matched, you may still need to synchronize drums beats of the
two tracks. To do this, you will need to adjust the tempo/pitch of a track temporarily with the pitch bend
buttons ("–/+") or with the JOG WHEEL.

The following example describes how to sync the beats of Deck B to the beats of Deck A. After matching the
BPM’s, adjust the pitch temporarily as follows:

or or

The faster you rotate the JOG WHEEL or the longer you hold the "–/+" buttons, the greater the change in
pitch. When you release the JOG WHEEL or "–/+" buttons, the deck will return to its usual tempo.

Press PLAY on Deck A

Press PLAY on Deck B.
Listen to Deck B or look

at the BPM on the LCD.

If Deck B is faster
than Deck A, slow

down Deck B.

If Deck B is slower
than Deck A, speed

up Deck B.

If Deck B is behind, rotate its JOG WHEEL
clockwise or press "+" to bend the pitch up
until its beats are synced with those of the

other deck.

If Deck B is ahead, rotate its JOG WHEEL
counterclockwise or press "–" to bend the
pitch down until its beats are synced with

those of the other deck.

10

BEATKEEPER & INTERLOCK

The CDN88 MP3 includes the Numark-patented Beatkeeper™ technology. The
Beatkeeper automatically tracks beats based on the frequencies and rhythmic patterns in
the music. It detects and displays the track's BPM in the LCD and displays four-count
information (i.e., where you are in a four-beat measure) in the MARCHING BAR GRAPH.

MARCHING BAR GRAPH: Most dance and rock music is structured around four-beat
increments called measures. The MARCHING BAR GRAPH's bottom LED is for the first
beat of a measure – the “downbeat.” Most music starts on the downbeat so the music will
begin from this point. Occasionally this may not be the case, or you may wish to reset it. To
reset the downbeat, simply press the TAP button once where you want to set the new
downbeat as the music is playing or paused.

TAP: This button can recalculate a track's BPM or reset its downbeat.

y To recalculate a track's BPM: tap the TAP button on the downbeat of a measure (during

playback) and hold it for four seconds. The Beatkeeper will automatically detect the track's
BPM. You can also tap the TAP button in time with the beats of the track, which will manually enter a
new BPM (this BPM reading will be based upon the average of your last eight taps).

y To reset a track's downbeat: press the TAP button once on the downbeat during playback.

SYNCED BAR GRAPH: The bar graph between the two decks' MARCHING
BAR GRAPHS compares the music from both units. When the BPMs and
downbeats of the two decks are matched and synced, the SYNCED BAR
GRAPH's green LEDs will light up.

INTERLOCK: This button will automatically match both decks' BPMs and sync their
downbeats. Before using this function, be sure the "Master Deck" (the deck whose
BPM and downbeat will determine the BPM and downbeat when using INTERLOCK)
has the correct BPM and downbeat. The Master Deck is always the first unit to be
playing. The deck whose BPM and downbeat will be changed to match the Master Deck is called the Slave
Deck. As soon as the Master Deck is stopped, the Slave Deck becomes the new Master Deck.

We recommend activating KEY LOCK before using INTERLOCK, which will automatically change the pitch of
the Slave Deck. Once INTERLOCK is pressed, you will see the BPM of the Slave Deck change to match the
Master Deck and the PITCH (in the LCD) change the amount needed to match the two decks. While
INTERLOCK is engaged, all pitch functions of the Slave Deck will be inactive and only follow the pitch
changes to the Master Deck. Other functions, such as looping, on the Slave Deck will now also be beat­synced with the Master Deck.

Please note:

• If both decks are playing, the Slave Deck will adjust to match to the nearest beat of the Master Deck.

• If PLAY / STUTTER is pressed, the Slave Deck will start with the next beat of the Master Deck.

• If the Slave Deck's AUTOSTART button is pressed during INTERLOCK, it will automatically start the

next time its beats are matched with the Master Deck.

• INTERLOCK may automatically deactivate when effects are engaged that can not be beat-aligned,
such as Scratch.

During playback, if the Slave Deck becomes the Master Deck or is released from INTERLOCK, its new pitch
will often be different than the current position of the PITCH SLIDER. The PITCH SLIDER will not function
until it is brought to the new position. Adjust the PITCH SLIDER as indicated in the LCD.

Example:

If the LCD says "PITCH INC +Æ 4.5," move the PITCH SLIDER in the positive direction 4.5%. If
it says "PITCH DEC –Æ 13.1," then move the PITCH SLIDER in the negative direction 13.1%. As you get
closer to the correct position, the number in the LCD's PITCH indicator will reduce until you are at the current
pitch. After this has been achieved, all pitch functions will be re-enabled and can be adjusted normally. If the
unit is stopped, the pitch will automatically reset to the current position of the PITCH SLIDER.

11

KEY LOCK & KEY CHANGE

The CDN88 MP3 uses exclusive technology to lock the key of the music in place at the
current pitch or change it from the current position. This is different than “master tempo”
often found on many modern units because KEY LOCK locks to whatever the current
pitch position is (rather than the "0%" pitch position). This means you can lock the track to any key – not just
its original key – then change the speed of the song without changing the key.

KEY LOCK: Pressing KEY LOCK holds the key in place. The LCD will show a "lock" icon to
indicate the current key is locked. If the tempo is changed with the PITCH SLIDER, the key of the
track will remain unchanged (though you can change it with the "–/+" buttons). If KEY LOCK is
engaged and the deck's track changes, the track will be locked at 0%. If KEY LOCK is deactivated when the
deck is paused, the deck's pitch will reset to match the current pitch position.

KEY CHANGE: While holding down the KEY LOCK button you can press the "+" or "–"
buttons to change the key. The key can be raised up to one octave above the original
key or lowered as many as five octaves below the original key. The KEY indicator in the
LCD will show the key change up to 12 half-steps above or 19 half-steps below the
normal key (any key below 19 half-steps will be denoted by an "L" in the display).

AUTOSTART

The AUTOSTART button serves two functions, depending on how it is set.

Interlock Play Start: If the Slave Deck's AUTOSTART button is pressed during INTERLOCK, it will
automatically start the next time its beats are matched with the Master Deck.

Relay Play: This function will automatically start play on that deck (which becomes the Slave Deck) after the
track on the opposite deck (now the Master Deck) is finished. To activate Relay Play, press the
AUTOSTART button (without INTERLOCK engaged) on the Slave Deck. The LCD will read "RELAY." When
the Master Deck has finished playing, it will send a signal to the Slave Deck to start playback. The Slave
Deck will start automatically and the Master Deck will pause and cue to the beginning of its next track. The
Master Deck will now become the Slave Deck.

In Continuous Play Mode, Relay Play allows the Master Deck to play the full CD before the Slave Deck is
allowed to play. In Single Play Mode, each deck will play one track before switching to the other.

You can designate how much time Relay Play takes to switch from one deck to the other by holding down
PROGRAM and pressing the AUTOSTART button. From here, you can:

y select "0" to relay playback immediately after the track

y select "1," "2," "3," or "4" to add that many seconds between playback of the decks

y select "-1," "-2," or "-3" to assign the Slave Deck to start playing that many seconds before playback on

the Master Deck has ended (creating an automatic segue)

To deactivate Relay Play, press the AUTOSTART button so the LCD reads "NO RELAY."

Note: This feature will also work in Program Mode, but if both decks are also in Single Play Mode, the
number of tracks programmed should be the same on each deck (to ensure playback does not stop
prematurely).

12

FADER START / REMOTE SWITCH START

This function allows for CD player control using most standard fader start-compatible mixers and switches.
First, follow the directions for connecting to your fader start-compatible mixer or switch.

1. Hold down PROGRAM and press TIME to toggle through the following

options:

y REMOTE FADER: The deck will activate with fader start. If you

move your mixer's crossfader toward that channel, the attached
deck will start playback. When the crossfader is moved away the
unit will cue or pause depending upon CD player setting.

y REMOTE ON – OFF: The deck will activate with an on/off push-

button switch (typically used for switching channels on guitar amps).

y REMOTE ON – ON: The deck will activate with a momentary switch (typically used for keyboard

sustain pedals).

2. Hold down the TIME button for two seconds.

y FADER PAUSE: The deck will pause when stopped.

y FADER CUE: The deck will pause and return to the Cue Point when stopped.

LOOPING OPERATIONS

LOOPING

A loop is any area of a CD that you choose to repeat with no breaks ("seamless"). On the CDN88 MP3, you
can set up to two loops per deck.

LOOP IN: The Loop
In Point is where
you want the loop to

start. The track's
initial Cue Point is also the default
Loop In Point for both loops and a
Stutter/Hot Start Point. To set a new
Loop In Point, press LOOP IN at the
desired point while the track is
playing. The LOOP IN button will
light up, indicating a new loop is set.
The RELOOP button will light up and "HOT" will be shown in the LCD, indicating a point has been set and is
accessible for stuttering. (By default, the Loop In Point also becomes the Stutter/Hot Start Point.)

Note: The deck will always remember a new set point as the Loop In or Stutter/Hot Start Point until you
actually set a new Loop In Point or load a new CD. The new point will be accessible until you eject the CD.
If you change tracks and you previously set a Loop In Point on another track, pressing RELOOP will jump to
that point.

LOOP OUT: The
Loop Out Point is the
end point of a loop.

The first time you
press LOOP OUT while playing a
track, the LOOP OUT button will
flash as the song automatically
returns to the Loop In Point and
continues to play. When the song
reaches that Loop Out Point, it will return to the Loop In Point and repeat. (The LOOP IN button will also be
flashing during a loop.)

To release the loop, press LOOP OUT while in the loop. Playback will continue forward when the track
passes the previously set Loop Out Point. The LOOP OUT button will be lit solid indicating that the loop will
be remembered if RELOOP is pressed.

Note: You can also use a

momentary switch in the "ON­OFF" setting. In this case, the
deck will play only while the
switch is depressed. When it is
released, it will either cue or
pause depending upon the
mode.

13

Note: The Loop Out Point will be erased if LOOP IN is pressed or if a new Cue Point is set after the Loop
Out Point. If this happens, RELOOP will not be possible.

SMART LOOPING: The Beatkeeper and looping functions can work together to set perfect loops every time.
For this to work correctly, the Beatkeeper must be on the beat. To activate Smart Looping, hold down
PROGRAM and press RELOOP. All Loop Points and stuttering will now play perfectly to the beat of the
music.

MOVING LOOP POINTS

The Loop In Point can be moved while the music is playing by pressing LOOP IN wherever you want to set it.
The next time the Loop Out Point is reached, the track will return to this new Loop In Point. If LOOP IN is
pressed after the Loop Out Point, it will clear that Loop Out Point.

The Loop In Point can also be edited while paused by holding down CUE, pressing LOOP IN, then rotating the
JOG WHEEL to search for a new Cue Point location. Press LOOP IN again to set the new Loop In Point at this
location. (You can check your Loop In Point by pressing RELOOP.)

The Loop Out Point can also be moved while a loop is playing. Press LOOP OUT to release the old Loop
Out Point and press it again at the new desired point.

14

RELOOPING / STUTTERING

The RELOOP button performs two different functions, depending on the loop setting:

Reloop: This function can only be used if Loop In and Loop Out Points are set. RELOOP
automatically returns the track to the Loop in point and will play the loop until it is released
with the LOOP OUT button.

Stutter: This function starts playback from previously set Stutter/Hot Start Points. Set your Stutter/Hot Start
Point the same way you would set a Loop In Point. (Remember that this button also serves as a reloop
button, so if a loop out has been set, the deck will also loop until released.) This function lets you set three
Stutter/Hot Start Points. The first is based on the Cue Point while the second two are based on the Loop In
Points.

Note: The deck will always remember new Stutter/Hot Start Points until you actually set a new Loop In Point
or load a new CD. The new point will be accessible until you eject the CD. If you change tracks and you
previously set a Loop In Point on another track, pressing RELOOP will jump to that point.

15

USING EFFECTS

EFFECT SELECTION (Single Effect Mode): To select and activate an effect, press its button. It will light
and the effect will be indicated in the LCD. To put the effect into Hold Mode or to activate the second row of
effects, press the HOLD button. The HOLD button will light indicating "hold" has been activated. To
deactivate an effect, tap it again.

EFFECT SELECTION (Multiple Effects Mode): Hold PROGRAM
and press HOLD to activate or deactivate Multiple Effect Mode.
The LCD will indicate "MULTIFX" or "NO MULTIFX." Select an
effect by pressing an EFFECT BUTTON and move the JOG
WHEEL to the desired parameter. Then, press a second EFFECT
BUTTON. The first EFFECT BUTTON will flash while the second
effect will be solidly lit. To deactivate the second effect, press the solidly lit EFFECT BUTTON. You can use
up to four effects at the same time (this includes both decks together).

Some effects, like Scratch and Reverse, are always available. Others, like Phaze, Sonar, and Slide, use two
effect values while the remaining effects allow one. If more than the allowed values are attempted, they will
not activate.

For example:

• You can have Echo and Isolate engaged on Deck A and Scratch and Sonar on Deck B.

• You can have Phaze engaged on Deck A and Slide on Deck B

• You can have Phaze and Slide engaged on Deck A but only Scratch or Reverse on Deck B.

EFFECT PARAMETER SELECTION: Once an effect is engaged, rotate the JOG WHEEL to set the desired
parameter for that effect. The parameter for most effects will be shown in the LCD's TEXT DISPLAY and will
be "remembered" if that effect is disengaged then reengaged. (Note: For all effects except Reverse, the
JOG WHEEL will not be able to pitch bend while adjusting parameters, so you must use the "–/+" buttons to
pitch bend in these cases.)

EFFECTS

SCRATCH – This effect enables the JOG WHEEL to scratch

the music while it is playing. Moving the JOG WHEEL
emulates the scratching of a record (by moving the platter).
This effect has four modes. By holding PROGRAM then the Scratch EFFECT BUTTON, you can toggle
between the following options:

y Scratch 1: The deck automatically resumes playback when the wheel stops moving.

y Scratch 2: The deck will stop when the JOG WHEEL is brought to a stop and will resume playback

when the JOG WHEEL is pushed forward.

y Scratch 3: The deck will scratch the audio from the buffer until the JOG WHEEL is released. When

released, the track will jump ahead to the point where the music would have been if it had not been
interrupted (similar to the Bleep effect).

y Scratch 4: The deck scratches from the last set Cue Point until the JOG WHEEL is pushed forward.

When released, the track will play from that point. This allows you to scratch from a set “sample.”

SCRATCH HOLD – This effect works like Scratch except
playback will not resume when the JOG WHEEL is pushed
forward. Instead, it emulates scratching a record on a
platter with the motor off.

16

PHAZE – Creates an effect similar to the sound of an
airplane taking off. The JOG WHEEL controls the rate of
this effect. If the JOG WHEEL stops, the effect will
automatically return to the "0." If the effect is in Hold Mode, the sound (as set by the JOG WHEEL) will stay
constant until it is adjusted with the JOG WHEEL, deactivated, or taken out of Hold Mode.

SONAR – Creates a hollow, metallic effect. The JOG
WHEEL controls the rate of this effect. If the JOG WHEEL
stops, the effect will automatically return to "0." If the effect
is in Hold Mode, the sound (as set by the JOG WHEEL) will stay constant until it is adjusted with the JOG
WHEEL, deactivated, or taken out of Hold Mode.

SLIDE – Smoothly changes the key of the music with the
motion of the JOG WHEEL. The LCD's KEY indicator will
show the key change as the JOG WHEEL is moved. If the
JOG WHEEL stops, the effect will automatically return to "0." If the effect is in Hold Mode, the sound (as set
by the JOG WHEEL) will stay constant until it is adjusted with the JOG WHEEL, deactivated, or taken out of
Hold Mode.

ECHO – Adds echo to the music based on the Beatkeeper.
The default parameter is “0” (no echo). If you move the JOG
WHEEL to the right the EFFECT PARAMETER display will
read "1-64," "1-32," "1-16," "1-8," "1-4," "1-2," and "1-1,"
indicating the amount of echo added to the unit. If you move
the wheel to the left you will create Reverse Echo. (Reverse
Echo essentially plays the music before the sound actually
occurs in playback. This means the audio will be played out
of the buffer. If the buffer becomes unavailable, Reverse
Echo will stop until the buffer is regained.)

At "1-1," the echo will last for one full measure (four beats).
If you deactivate then reactivate Echo, the last set parameter
will be remembered.

A.D. (Artificial Decimation) – Reduces the bitrate of the music
creating distortion with increasing intensity.

CHOP – Chop breaks up the music by turning the volume on
and off based upon the BPM of the Beatkeeper. (This effect
works best when the Beatkeeper is properly aligned.) When
the effect is first activated the music will play the section then
turn off for a section.

The first activation of Chop occurs at every eighth note (half
of every beat). The LCD's BPM indicator will show "1-8,"
which means one measure (four beats) of music has been
broken into eight parts.

Rotate the JOG WHEEL counterclockwise to decrease the
parts to "1-4," "1-2," and "1-1" (at "1-1," the music plays for
four beats then is silent for four beats). Rotate the JOG
WHEEL clockwise to increase the parts to "1-16," "1-32," or
"1-64." If you deactivate then reactivate Chop, the last set parameter will be remembered.

17

PAN – Pan alternates between playing right and left audio
channels based upon the BPM of the Beatkeeper. (This
effect works best when the Beatkeeper is properly aligned.)

The first activation of Pan alternates between right and left
audio channels every eighth note (half of every beat). The
LCD's BPM indicator will show "1-8," which means one
measure (four beats) of music has been broken into eight
parts.

Rotate the JOG WHEEL counterclockwise to decrease the
parts to "1-4," "1-2," and "1-1" (at "1-1," the right channel
plays for four beats then the left channel plays for four
beats). Rotate the JOG WHEEL clockwise to increase the parts to "1-16," "1-32," or "1-64." If you
deactivate then reactivate Pan, the last set parameter will be remembered.

ISOLATE – This isolation filter lets you play only a specific
frequency in the music. Rotate the JOG WHEEL to move
the selected frequency through the audio spectrum. If you
deactivate then reactivate Isolate, the last set parameter will
be remembered.

KILL – This filter eliminates a specific frequency in the
music. Rotate the JOG WHEEL to move the selected
frequency through the audio spectrum. If you deactivate
then reactivate Kill, the last set parameter will be remembered.

REVERSE – Plays the music backwards until it is
deactivated. There is no limit to the amount of time you can
reverse.

BLEEP – A temporary "forward reverse" function for
“bleeping” obscene lyrics or creating interesting effects.
Once its EFFECT BUTTON is pressed, the music will play
backwards from buffer until Bleep is deactivated or until the
buffer runs out. At that point, the music will play forward
from the point where the track would have been if the button
had never been pressed.

For example, if Bleep is activated for five seconds at the
0:10 mark of a song, you will hear the audio from 0:05 – 0:10
in reverse. When you deactivate Bleep, normal (forward)
playback will resume at 0:15.

Note: The buffer time allotted for this operation varies with the number of loops set and anti-shock buffer
available.

PROGRAM FUNCTIONS

The PROGRAM button provides several functions depending upon the combination of other buttons used.

Track Sequence Programming – Press PROGRAM while the deck is stopped with a
loaded CD and “PROGRAM” will light. Select each track to be programmed, pressing
PROGRAM between each selection. Press PLAY / STUTTER to play the Track Sequence
Program. To exit and erase program, hold PROGRAM for more than two seconds while the
deck is stopped, eject the CD, or turn off the power.

You can activate the following functions by holding down the PROGRAM button then pressing the
appropriate button:

Effect Options * – Pressing PROGRAM and an EFFECT BUTTON will offer alternate

options to that effect (if available). For instance, pressing the Scratch EFFECT BUTTON
will allow you to toggle between "Scratch 1," "Scratch 2," "Scratch 3," and "Scratch 4." See
USING EFFECTS for more information.

Multiple Effect Mode * – Switches the deck between Single and Multiple Effects Modes.
See USING EFFECTS for more information.

End-of-Track Silence Elimination * – This will let you eliminate the silence at the end of
tracks. (The CDN88 MP3 already removes any silence at the beginning of tracks
automatically.) This is useful for eliminating all the gaps between songs when playing a CD
in Continuous Play Mode. The LCD will indicate "NO SPACE" when this function is
engaged or "_SPACE" when the function is disengaged (allowing the silence at the end of
tracks to play).

Cueing Style Selection * – This will let you use hear a smooth "scratch" sound or
traditional "stutter" sound when cueing with the JOG WHEEL. The LCD will indicate
"SCRATCH" when the "scratch" style is active. This indication will be absent when the style
of cue is "stutter."

Braking Time * – To adjust the braking time – the speed at which playback stops – press
PROGRAM, press PAUSE, and rotate the JOG WHEEL until the desired seconds are
shown on the LCD. After this, you can toggle between a braking time of "0" and the time
you just set by pressing PROGRAM then PAUSE twice.

Startup Time * – To adjust the startup time – the speed at which playback begins – press
PROGRAM, press PLAY / STUTTER, and rotate the JOG WHEEL until the desired
seconds are shown on the LCD. (The stutter function will not be affected by this setting.)
After this, you can toggle between a braking time of "0" and the time you just set by
pressing PROGRAM then PLAY / STUTTER twice.

Relay Time * – You can designate how much time Relay Play takes to switch from one
deck to the other by holding down PROGRAM and pressing the AUTOSTART button. From
here, you can:

y select "0" to relay playback immediately after the track

y select "1," "2," "3," or "4" to add that many seconds between playback of the decks

y select "-1," "-2," or "-3" to assign the Slave Deck to start playing that many seconds

before playback on the Master Deck has ended (creating an automatic segue).

Remote Start * – This will let you decide the fader start or remote switch start settings for
the deck. See FADER START / REMOTE SWITCH START for more information.

Automatic Door Close Protection * – This option automatically closes the door at the
specified time. The LCD will indicate options of 30 seconds, 60 seconds, 120 seconds, and
"no" for no auto close.

19

Smart Looping – When Smart Looping is active, all Loop Points and stuttering will play
perfectly to the beat of the music (as long as the Beatkeeper is accurate – see
BEATKEEPER & INTERLOCK for more information). "SMART LOOP" will be shown on the
LCD when this function is active.

Sleep Mode – The unit will automatically enter Sleep Mode after 15 minutes of inactivity. In
this mode the unit will still start instantly from its buffer, but the CD player's laser will turn off
to extend its life. (This feature can be turned off.)

* This setting will be remembered at power down.

CUE / LOOP POINT STORAGE & RECALL

To SAVE Cue and Loop Points on the current audio CD:

1. With an audio CD (with Cue and Loop Points) loaded, hold PROGRAM and press LOOP IN.

2. The LCD will show "CUE STORE" for one second, indicating your Cue and Loop Points are
saved.

To RECALL Cue Points on the current audio CD:

1. Hold PROGRAM and press LOOP OUT.

2. The LCD will show "CUE FETCH" to indicate Cue Point loading. (If the audio CD doesn't have
Cue Points stored on the CD player, then the LCD will show "NO FETCH.")

3. All Cue and Loop Points will be restored in addition to BPM and downbeat information for
immediate access to Beatkeeper functions.

Notes:

y If over 1024 audio CDs have Cue Points written, the oldest Cue Points will be overwritten.

y If new Cue Points are detected on an audio CD, this new Cue Point data will overwrite the old Cue

Point data.

UPGRADING YOUR UNIT

This CDN88 MP3 contains the latest software available at the time of manufacturing. Our engineering staff
will be working hard to improve and offer additional features in the future. The software has been designed
to be easily updated by you through supplied updates from Numark. To obtain the latest software version,
visit us on the web at http://www.numark.com

.

To check your unit’s software version press PROGRAM then the "+" button. Three sets of numbers will
appear. Your unit's software version will be in the set of numbers shown in the "seconds" display on the
LCD. (Example: If "R1 05 34 09" appears, you have Version 34, Revision 1.)

AUDIO CD PROGRAMMING PROCEDURE

1. Go to www.numark.com

and download the latest version of the CDN88 MP3's software.

2. Load the file onto a computer and burn the file onto an "audio CD." (We recommend burning the CD at
the slowest speed possible to ensure its accuracy.) Remember to finalize the CD.

3. Turn on the CDN88 MP3 (without a CD loaded).

4. Load the burned CD into the unit with the EJECT button. Do not close the drawer by pressing PLAY /
STUTTER.

5. Wait until the LCD indicates the time remaining.

6. Press PLAY / STUTTER. In the EFFECT PARAMETER display, you will see the word "TEST" as the
time counts down. The unit will repeat the cycle and indicate "BUSY" while it is updating the software.

7. When it is finished, the CD should eject automatically and the LCD will read "GOOD."

8. Remove the CD and turn the unit off for three seconds before turning it on again.

9. Recalibrate the unit following the calibration procedure included with the software update.

Note: CD burning is dependent on the recording equipment and the CD player's ability to read the burned
information. If the unit ejects the CD during the procedure, remove the CD and try again. If it fails, try re­burning the CD. If this doesn’t work, contact us at [e-mail]

for a free upgrade CD.
