INTRODUCTION:
Congratulations on your purchase of a Gemini CDX-802 CD Player.
Your state-of-the-art professional CD Player is backed by a three year
warranty that excludes lasers, which are covered by a separate one
year warranty. Prior to use of this unit, we suggest you carefully read
the following intructions.
Your Gemini CDX-802 CD Player comes equipped with ADCS (Automatic
Disc Calibration System), a unique state-of-the-art feature. CDs are
produced by a variety of manufacturers and recorded by many different
professional companies as well as the do-it-yourselfers at home. Therefore,
all CDs do not play the same. The ADCS automatically adjusts the laser in
your CDX-802 CD Player for each individual CD you insert into the tray, to give
you the best possible performance for every CD you play regardless of how it
was manufactured or how it was recorded. With this exclusive system you
always get consistent and reliable performance as well as exceptional
sound quality every time you play a CD... any CD.
CAUTIONS:
1. Do not use this CD player at temperatures below 41°F/5°C or higher than
95°F/35°C.
2. The apparatus should not be exposed to dripping or splashing, and no objects
filled with liquids such as vases should be placed on the apparatus.
3. Place the unit in a clean and dry location.
4. Do not place the unit in an unstable location.
5. When disconnecting the power cord from an AC outlet, always grasp it by
the plug. Never pull the power cord.
6. To prevent electric shock, do not remove the cover or the bottom screws.
There are no user serviceable parts inside. Please refer servicing to a
qualified technician.
7. Do not use chemical solvents to clean the unit.
8. Keep the laser pickup clean by keeping the tray closed.
9. Keep this manual in a safe place for future reference.
SAFETY CERTIFICATIONS:
Laser Diode Properties
Material: Ga - Al - As
Wavelength: 755 - 815 nm (25° C)
Laser Output: Continuous Wave, max. 5mWCAUTIONS
LINE VOLTAGE SELECTION:
The Gemini CDX-802 CD Player is a dual voltage unit operating at
115 or 230 volts. Be sure to set the proper voltage:
1. Place the head of a screwdriver in the center of the VOLTAGE
SELECTOR (1) switch found on the rear panel.
2. Slide the switch to 115 or 230 volts.
3. Do not force or twist the switch. Excessive force may cause damage.
If the switch does not move smoothly, contact a qualified technician.
CONNECTIONS:
1. Plug one end of a set of RCA connectors into the two LINE OUTPUT
JACKS (2) on the back of your CD unit.
2. Plug the other end of the RCA connectors into any of the available
line level input jacks on your mixer. If you are playing the CDX-802
through a receiver, you can plug the RCA connectors into the CD or
AUX INPUT JACKS located on the receiver. If there are no CD or AUX
INPUTS, use any line level (not phono) input.
FUNCTIONS:
POWER SWITCH: After making sure the VOLTAGE SELECTOR (1)
switch is properly set, plug the unit in and press the POWER (3) button.
The unit will turn on. Pushing POWER (3) a second time turns the unit off.
DISC TRAY: The DISC TRAY (5) is where the CD is held during loading,
unloading and playback. Pressing OPEN/CLOSE (4) opens or closes
the tray. The DISC TRAY (5) holds both 12 cm and 8 cm CDs and
automatically closes after remaining open for three minutes.
NOTE: TRAY WONT OPEN WHEN THE CDX-802 IS IN THE PLAY MODE.
OPEN/CLOSE: Press OPEN/CLOSE (4) to load or remove a CD from the
DISC TRAY (5).
DISPLAY: The DISPLAY (6) shows total tracks; track number; pitch value;
single-auto cue; continue (continuous play); and three different time
displays: track time elapsed, track time remaining and total time remaining
on disc. Time is measured in minutes, seconds and frames.
PLAYBACK DISPLAY: The PLAYBACK DISPLAY (7) displays the
play time remaining for each track. The display flashes slowly when
the track has 15 seconds remaining and pulses rapidly when play
time is down to five seconds.
PLAY/PAUSE : Each press of PLAY/PAUSE (8) causes the operation
to change from PLAY to PAUSE or PAUSE to PLAY.
TRACK SKIP : The TRACK SKIP (9) buttons let you select
the track to play.
SEARCH JOG WHEEL: The SEARCH JOG WHEEL (10) has two
functions. Use the SEARCH
JOG WHEEL (10) to make fine adjustments
in PAUSE mode. Use the SEARCH JOG WHEEL (10) to bend the pitch
for precise synchronization in PLAY mode.
SEARCH DIAL: Use the SEARCH DIAL (11) to select the scanning
direction and speed of your CD. Turning the dial in a clockwise
direction scans forward while a counter-clockwise turn scans
the track in reverse. Scan speed increases as the dial is turned.
STOP : The STOP (12) button ends CD play.
TIME: The TIME (13) button switches the time display between the
three available choices listed under DISPLAY (6).
FLY CUE: The FLY CUE (14) function lets you set cues “on the fly” with the
press of a button. Press FLY CUE (14) when the disc reaches the musical
location you wish to make your cue or start point. The cue point is now
programmed. Press CUE (15) to return to the cue point. Press PLAY/PAUSE
(16) and the unit starts from the pre-programmed spot.
CUE: With the unit in the PLAY mode (PLAY/PAUSE LED is green) and
after the cue point has been programmed, pressing CUE (15) will
cause the CD player to enter the PAUSE mode (green PLAY/PAUSE
LED blinks) at the programmed cue point (the CUE LED glows yellow).
Holding down the CUE (15) button changes the function to PREVIEW
and starts the CD from the programmed cue point. Releasing the CUE
button (15) will return the CD laser to the preset cue point.
LOOP: After a cue point is memorized, pressing the B/EXIT (16) button in
PLAY mode, (the CUE LED blinks yellow), repeats the section between
the cue point and the point where the B/EXIT (16) button was pressed.
Press the B/EXIT (16) button again or pause play to exit the repeating
play.
BOP/RELOOP: The BOP/RELOOP (17) button has two functions. To
return to a previously saved loop from normal play, press the BOP/
RELOOP (17) button after saving the loop. To return to and instantly play
from a previously saved cue point, press the BOP/RELOOP (17)
button after setting the cue point (if you do not have a loop saved).
SINGLE-AUTO CUE/CONTINUOUS: Pressing SINGLE-AUTO CUE/
CONTINUOUS (18) activates the AUTO CUE FUNCTION. The AUTO
CUE causes the CD to pause at the recorded beginning of the next track
and allows you to start play into the next song with no space in
between songs. Pressing SINGLE-AUTO CUE/CONTINUOUS (18) a
second time will activate the CONTINUOUS function. This causes the
CD to repeat play continuously until SINGLE-AUTO CUE/CONTINUOUS
(18) is pressed a third time to deactivate the CONTINUOUS function.
PITCH: Pushing the PITCH button (19) activates the PITCH section of the
unit (PITCH LED glows red). The pitch of the CD will change according
to the position of the PITCH SLIDE (20).
PITCH BEND : Pushing the PITCH BEND (21) buttons will
automatically raise the pitch up to +4% or lower the pitch down to
-4% from the existing setting. Releasing the buttons returns pitch to the
original setting. Use this function to match the pitch bend when mixing
from one song to another.

(4)
4%, 8% and 16%:
Use the 4%, 8% and 16% (22) buttons to assign the
percent the pitch control slide will have. The 4% button will assign +/-
4% to the PITCH CONTROL SLIDE (20). The 8% button will assign +/-
8% to the PITCH CONTROL SLIDE (20). The 16% button will assign +/-
16% to the PITCH CONTROL SLIDE (20). The PITCH (19) must be ON
for the 4%, 8% and 16% (22) buttons to work.
INSERT: Set a cue point (using the CUE (15), FLY CUE (14) or SEARCH
JOG WHEEL (10). From this cue point you will be able to sample up to
10 seconds of a musical phrase or sound. When you push and hold the
INSERT (23) button you will be able to insert that phrase or sound at
any spot in the music that is currently playing, replacing what is playing
in that spot with up to 10 seconds of the piece you have sampled.
When you release the INSERT (23) button the music will continue
uninterrupted.
NOTE: YOU CAN ONLY USE YOUR “SAMPLE” WITH YOUR CURRENT
CD. ONCE YOU OPEN THE DISC TRAY TO CHANGE CDS, YOUR
“SAMPLE” WILL BE AUTOMATICALLY DELETED.
DIGITAL OUTPUT JACK: Connecting any type of DAT, MD, HARD
DRIVE, or other such items which accept digital signals to the BNC
(24) output connector on the rear panel of your CDX-802 allows you
to record a digital signal from CD.
OPERATING INSTRUCTIONS:
1. Make sure that the VOLTAGE SELECTOR SWITCH (1), found on the
rear panel, is set for the proper voltage. Plug the unit in and press the
POWER SWITCH (2). The unit is ON. Pushing POWER (1) a second
time turns the unit OFF.
2. Press OPEN/CLOSE (4) and place a CD in the DISC TRAY (5). Press
OPEN/CLOSE (4) again. The tray will close.
3. Push TRACK SKIP (9) to select the track you wish to play.
4. Press PLAY/PAUSE (8) and the unit will instantly play.
FLY CUE & CUE INSTRUCTIONS:
The FLY CUE (14) function lets you set cues “on the fly” with the press
of a button. Press FLY CUE (14) when the disc reaches the musical
location you wish to make your cue or start point. The cue point is now
programmed. Press CUE (15) to return to the cue point. Press PLAY/
PAUSE (8) and the unit instantly starts from this pre-programmed spot.
AND/OR:
1. To pre-program a cue point (the spot on a CD at which you want play to
start) select the proper track and push PLAY/PAUSE (8) so the unit
enters the PLAY mode (PLAY/PAUSE LED glows green). When the CD
reaches the approximate musical spot you wish to make your cue, push
PLAY/PAUSE (8) so the unit enters the PAUSE mode (PLAY/PAUSE LED
blinks). Move the SEARCH JOG WHEEL (10) forward or in reverse until
the precise spot at which you want CD play to begin is located. Push
PLAY/PAUSE (8). The cue point is now programmed. Press CUE (15) to
return to this pre-programmed cue point at any time. Push PLAY/PAUSE
(8) and the unit will instantly play from the pre-selected spot.
2. To fine tune your pre-programmed cue point, push PLAY/PAUSE (8)
so the unit enters the PLAY mode. Push the CUE button (15) and the
CD will return to the cue point you programmed in step #1 and begin play
from that point. If you decide this cue or starting point is okay, leave the
unit alone until you are ready to play.
3. If, however, the selected spot is not exactly where you want it, push
the CUE (15) button while the CD is playing and the disc will return to
the pre-programmed cue point. Locate the exact spot on the CD at
which you want play to start by turning the SEARCH JOG WHEEL (10).
Push PLAY/PAUSE (8) to pre-program this new cue point. Press the
CUE (15) button to pause play at the new cue point. Push PLAY/
PAUSE (8) at any time and the unit will play from the pre-selected spot.
ROBO START INSTRUCTIONS:
INSINGLE-AUTOCUEMODE:
Use ROBO START (25) in SINGLE-AUTO CUE MODE to alternate play
between the CDX-802’s two CD players (one track from one side, then
one from the other). In SINGLE-AUTO CUE MODE play starts
immediately with no blank or “dead” space. ROBO START (25) causes
one side of the CD player to play when the other side is paused.
1. Engage SINGLE-AUTO CUE MODE with the SINGLE-AUTO CUE/
CONTINUOUS (18) button .
2. Press the ROBO START (25) button to activate ROBO START (25). Play
will alternate between the two CD players. At the end of a track, the
playing side pauses and the other CD deck plays a track. At the end of
this track, the playing side pauses and the first CD deck resumes play.
IN CONTINUOUS MODE OR DURING NORMAL PLAY:
If you use the ROBO START (25) function without SINGLE-AUTO CUE
MODE (in CONTINUOUS MODE or during normal play), CD deck play does
not alternate automatically. The PLAY/PAUSE (8) button must be pressed
on the playing deck for the second deck to play.
1. During normal play, set a cue point on the second CD deck.
2. Press the ROBO START (25) button to activate ROBO START.
3. Press PLAY/PAUSE (8) button on the playing side to start play
from the cue point on the other CD deck.
NOTE: PAUSING PLAY IN THE MIDDLE OF A TRACK CAUSES THE
OTHER CD DECK TO PLAY. WHEN THE NEW TRACK ENDS, PLAY
RESUMES ON THE FIRST CD PLAYER FROM THE POINT AT WHICH
IT WAS PAUSED.
TROUBLESHOOTING:
• If a disk will not play, check to see that it was loaded correctly (label side up)
and that the CD unit is on a flat, level, stable surface. Check disc for dirt,
scratches, spills, etc.
• If the disc spins but there is no sound, check the cable connections. If they are
okay, check your amplifier or receiver.
•If the CD skips, check it for dirt, oil or scratches. Do not assume
that the CD player or laser is defective. Many CDs are recorded “out of spec” and
skip on most or all CD players. Before sending the unit to an authorized Gemini
service technician, insert a disc that plays properly in another unit.
