layed out within easy reach of the right or left hand.
Playback tempo and beat of two selections
can be combined easily.
÷ Playback starts immediately through use of the
memory function and DSP (Digital Signal Processor).
÷ Playback tempo of two selections can be aligned
with the TEMPO control knob (variable range :
±10%, stroke : 100 mm/4-inch). And the beat of
two selections can be aligned with the Jog dial.

point can be recalled in an instant.
÷ Cue point monitoring function (*6) which allows
monitoring of the set cue point.
÷ The position being played is displayed by the bar-
graph display which allows the elapsed or remaining
playback time to be read visually.

Pick up protector
When the door is open, a pickup protector is closed to
protect the pickup.
Floating structure preventing vibration
This player employs a structure which insulates the
unit from shock. Selections can be played without
sound skipping regardless of the DJ's rough operation.
(*1) Starting playback immediately
When the CD player is in playback standby (pause) mode,
the disc continues to rotate and the pick up jumps back to
the same track after every rotation. As a result, the user
can switch from pause to playback with a maximum time
lag of about 0.3 seconds.
When seamlessly connecting two selections, it is necessary
to eliminate the time lag between the tracks and start the
second selection immediately after the first one stops
To do this, this player memorizes the first 2.1
seconds of the selection so that it can instantaneously start
playing when the PLAY/PAUSE button is pressed. After the
first 2.1-second time period is played, the player uses its
link memory function to continue the selection by seamlessly
connecting the playback data with the end of the memorized
data (playback is carried out through memory). With this
operation, it is possible to start playback within 0.01 seconds
after pressing the PLAY/PAUSE button.
Moreover, this function can be used not only at the start of
a selection but at any point where you want the playback to
begin through use of the auto cue function.
(*2) Beat search operation using the Jog dial
When two selections are combined, the Jog dial is used to
align the BPM and rhythm (speed and timing) between the
two selections. After playback tempo is aligned with the
TEMPO control knob, turn the Jog dial clockwise.
tempo of playback increases up to +12.7%.
counterclockwise decreases the tempo down to 12.7%.
When the Jog dial is released, the tempo returns to the
setting of the TEMPO control knob. Through this operation,
the beat of playback can be aligned.
(*3) Master tempo function
Playback speed can be changed ±10% in 0.1% increments
with the TEMPO control knob. But the pitch of playback
also changes, and vocals become unnatural.
master tempo function is set to ON, the key control is
processed by the DSP, and the pitch of playback is converted
to the original pitch. Even if the tempo is changed with the
TEMPO control knob, the pitch of playback is never changed.
(*4) Loop playback function
Using a single CD player, this function lets you perform a
"break beat" action similar to when a DJ uses two turntables
to repeatedly play the same phrase. Normally when using a
single player there is a search time lag between when the
phrase ends and when the start of the phrase begins playing
again. To eliminate this lag, this player memorizes the first
2.1 seconds of the loop playback data ahead of time and
plays this data while the player searches for the start point,
then seamlessly connects the playback sound with the
memorized sound to continue the phrase, realizing a true
loop playback function with no time lag.
(*5) Advanced loop function
When the loop play function is used, the advanced loop
function allows you to designate the loop start point during
play. By designating the loop end point after it, repeated
playback of the specified section without sound interruption
can be started. A RELOOP button is provided so that loop
playback using the specified loop section can be started in
(*6) Cue point monitoring function
During instantaneous start standby after the cue point has
been stored in memory, pressing and holding the button
allows you to listen to the music starting from the cue
point. When the button is released, the player returns to the
cue point and pauses there.
