left. The PLAYBACK DISPLAY (5) flashes quickly when the track
has 15 seconds left.
PLAY/PAUSE : Each press of the PLAY/PAUSE BUTTON (9)
causes the operation to change from play to pause or from pause

SEARCH BUTTONS : The SEARCH BUTTONS (7) are used
to move foward or reverse while in play mode. The SEARCH

point where you wish the track to start playing. This position on the
track is memorized as the cue point. See the CUE INSTRUCTIONS
section for more information.
STOP : The STOP BUTTON (11) will end the playing of the CD.

pause mode at the memorized cue point. Holding down the cue
button changes the cue function to preview (allowing you to hear the
music play from the cue point) and releasing the cue button returns
you to the preset cue point. If a cue point is not memorized, pressing
the CUE BUTTON (8) will cause the unit to return to the beginning of
that track.

track of the disc and continue to play).
OPERATING INSTRUCTIONS
1. Make sure that the VOLTAGE SELECTOR SLIDE SWITCH (3),
found on the rear panel, is set for the proper voltage. Plug the unit in
and press the POWER SWITCH (2).

CUE INSTRUCTIONS
1. To start the play at a point other than the beginning of a track, follow
these instructions:
First choose the track you wish to play, and then press the PLAY/
PAUSE BUTTON (9) so the unit goes into the play mode. Press the
PLAY/PAUSE BUTTON (9) to pause play at the spot where you want
the play to start -- the CUE POINT. Press the PLAY/PAUSE BUTTON
(9) again to save the cue point. Press the CUE BUTTON (8) to pause
play at the cue point (the unit will go into the pause mode and the
location indicated on the display will be the memorized cue point).

BUTTON (8). Press the PLAY/PAUSE BUTTON (9) to begin play
from the cue point.
Note: After a cue point is set, pressing the TRACK SKIP BUTTONS
(6) clears the cue point. When you press the CUE BUTTON (8) in
the new track, the beginning of that track will be the new cue
point.
2. Once you have saved a cue point you can fine tune or change the
memorized cue point:
To change a cue point, push the PLAY/PAUSE BUTTON (9) so the
unit plays from the cue point, then press the PLAY/PAUSE BUTTON
(9) at the spot you wish your new cue point to be. Press the PLAY/
PAUSE BUTTON (9) again to save the cue point. The unit will go into
the pause mode and the location indicated on the display will be the
new memorized cue point.

Page 3
To fine tune a cue point, pause play at the memorized cue point, then
use the SEARCH BUTTONS (7) to scan frame by frame (1/75th of a
second) to where you want play to begin. Press the PLAY/PAUSE
BUTTON (9) to save the new cue point.
Note: During fine tuning there will be a stutter effect (to help you
find the beat). The stuttering effect will end when you press the
PLAY/PAUSE BUTTON (9) to save the cue point. Also, during fine
tuning if you hold down the SEARCH BUTTONS (7), the unit will
scan quickly after 10 frames.
TROUBLE SHOOTING
•If the disk will not play, check to see if the disc was loaded correctly
(label side up). Also check the disc for excessive dirt, scratches, etc.
• If the disc turns but there is no sound, check the cable connections. If
they are okay, check your amplifier or receiver.
• If the CD skips, check the CD for dirt or scratches. Do not assume
that the CD player is defective. Many CDs are recorded out of spec
and will skip on most or all CD players. Before sending the unit in for
repair, try playing a CD that you are sure plays properly.

2. To reduce the risk of electrical shock, do not open the unit. There are
NO USER REPLACEABLE PARTS INSIDE. Please refer servicing to a
qualified service technician.
In the U.S.A., if you have any problems with this unit,
call 1-732-969-9000 for customer service. Do not return
equipment to your dealer.
3. Do not expose this unit to direct sunlight or to a heat source such as a
radiator or stove.
4. This unit should be cleaned only with a damp cloth. Avoid solvents or
other cleaning detergents.

and packaging. This will reduce the risk of damage during transit.
6. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
7. DO NOT USE ANY SPRAY CLEANER OR LUBRICANT ON ANY
CONTROLS OR SWITCHES.
Connections
1. Make sure that the POWER (22) switch is in the off position.
2. This unit comes supplied with a 15 volt AC adaptor. Plug the male pin
of the adaptor into the rear panel POWER JACK (6). Then plug the
adaptor into a proper power source.
3. To connect the mixer to your amplifier, use the OUTPUT AMP (1) jacks
on the rear panel.
4. The unit is equipped with one microphone input. The MIC JACK (15)
is a 1/4" (6.35 mm) and is located on the front panel.
5. On the rear panel are 2 stereo PHONO/LINE (3, 4) inputs, 1 stereo
PHONO (5) input and 1 stereo LINE (2) input. The PHONO/LINE
SWITCHES (8, 9) enable you to set the (3, 4) inputs to Phono or Line.
The PHONO (5) input will accept turntable inputs only. A GROUND (7)
screw for you to ground your turntables is located on the rear panel.
The stereo LINE (2) input will accept any line level input like a CD
player or a cassette player.
6. Headphones can be plugged into the front panel mounted
HEADPHONE (26) jack.
Operation
1. POWER ON: Once you have made all the equipment connections to
your mixer, press the POWER (22) switch. The power will turn on and
the POWER LED (21) will glow RED.
2. CHANNEL 1: The GAIN (12) control allows you to individually adjust
the gain of the channel. Switch # (13) allows you to select the PHONO
1 (5) or the LINE 1/PHONO 2 (4) input. The CHANNEL SLIDE (14)
controls the input level of this channel.
3. CHANNEL 2: The GAIN (23) control allows you to individually adjust
the gain of the channel. Switch # (24) allows you to select the LINE 2/
PHONO 3 (3) or the LINE 3 (2) input. The CHANNEL SLIDE (25)
controls the input level of this channel.
4. CROSSFADER SECTION: The CROSSFADER (20) allows the mixing
of one source into another. The left side of the CROSSFADER (20) is
CHANNEL 1 and the right side is CHANNEL 2. The CROSSFADER
(20) in your unit is removable and if the need arises can be easily
replaced. Crossfader units are available in three varieties. Part # RF-
45 (which is identical to the crossfader supplied with the mixer) has a
45 mm travel from side to side. Part # RF-30 is available with a 30 mm
travel distance. Also available is the PSF-45 with a special curve
designed for scratch mixing. Just purchase one of these crossfader
units from your Gemini dealer and follow these instructions:

3. Plug the new fader into the cable and place it back in the
mixer.
4. Screw the fader to the mixer.
5. TALKOVER SECTION: The purpose of the talkover section is to allow
the program playing to be muted so that the mic can be heard above
the music. When the TALKOVER (11) button is pushed, the
TALKOVER INDICATOR (10) will glow and the volume of all sources
except the Mic are reduced by -16 dB. LEVEL (17) controls the level of
