FEATURES
This CD player features the functions and operations of players used
in disco halls in addition to the functions of general CD players. This
player is made for commercial use in disco halls, etc.
Easy operation
÷ This player is a top loading type, allowing discs to be changed
smoothly.
÷ The equipped Jog dial and TEMPO control knob can be used like
the turntable of an analog record player.
÷ Buttons used frequently are designed oversized and 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). (*1)
÷ 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. (*2)
÷ By connecting this unit with the optional DJM-500 or DJM-300 DJ
mixer, the fader starting or back cuing of this unit can be controlled
from the channel fader or cross-fader of the mixer.
The mood of a disco hall can be reproduced using
digital technology.
÷ Master tempo function (*3) - Even though the playback tempo is
changed with the TEMPO control knob, the pitch of playback can
be automatically fixed, and the playback of two selections can be
combined smoothly.
÷ Loop playback function (*4) - A desired passage (less than 10
minutes) can be played back repeatedly and seamlessly.
÷ Advanced loop function (*5) which allows realtime setting of the
loop point during play. The set loop 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.
÷ The cue point can be set accurately with the frame search
function. (1 sec = 75 frames)
÷ BPM (Beats per Minute) can be adjusted precisely in 0.1%
increments by using the speed display.
Pick up protector
When the door is open, a pickup protector is closed to protect the
pickup.

(*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 playing. 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. The tempo of playback increases up to
+12.7%. Turning 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. When the 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 an instant.
(*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.
