Cautions
1. All operating instructions should be read before using this equipment.
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.
5. When moving this equipment, it should be placed in its original carton
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 (2) switch is in the OFF position. This unit
comes supplied with a 15 volt AC adaptor. Plug the male pin of the
adaptor into the rear panel POWER JACK (1). Then plug the adaptor
into a proper power source.
2. The PMX-120 is supplied with 2 sets of output jacks. The OUTPUT
AMP (3) jacks are used to connect to your main amplifier. The
OUTPUT REC (4) jacks can be used to connect the mixer to the
record input of your recorder enabling you to record your mix.
3. The DJ MIC (17) input (found on the front panel) accepts a 1/4"
connector and balanced and unbalanced microphones.
4. On the rear panel are 2 stereo PHONO/LINE (6, 10) inputs, 1 stereo
PHONO (11) input and 1 stereo LINE (5) input. The PHONO/LINE
SWITCHES (7, 9) enable you to set the (6, 10) inputs to Phono or Line.
The phono inputs will accept only turntables with a magnetic cartridge.
A GROUND SCREW (8) for you to ground your turntables is located on
the rear panel. The stereo line inputs will accept any line level input
such as a CD player, a cassette player, etc.
5. Headphones can be plugged into the front panel mounted
HEADPHONE (33) jack.
1. POWER ON: Once you have made all the equipment connections to
your mixer, press the POWER (2) switch.
2. CHANNEL 1: The GAIN (18) control allows you to individually adjust
the gain of the channel. Switch # (19) allows you to select the
PHONO 1 (11) or the PHONO 2/LINE 1 (10) input. The CHANNEL
SLIDE (20) controls the input level of this channel.
3. CHANNEL 2: The GAIN (27) control allows you to individually adjust
the gain of the channel. Switch # (28) allows you to select the
PHONO 3/LINE 2 (6) or the LINE 3 (5) input. The CHANNEL SLIDE (29)
controls the input level of this channel.
4. CROSSFADER SECTION: The CROSSFADER (26) allows the mixing of
one source into another. The left side of the CROSSFADER (26) is
CHANNEL 1 and the right side is CHANNEL 2. The CROSSFADER (26)
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:
1. Unscrew the outside FADER PLATE SCREWS (B). Do not
touch the INSIDE SCREWS (C).
2. Carefully lift the fader and unplug the CABLE (D).
3. Plug the new fader into the cable and place it back in the
mixer.
4. Screw the fader to the mixer.
The CROSSFADER CURVE BUTTON (21) allows you to adjust the kind
of curve the crossfader has. Depress the crossfader curve button
to make the curve steep and cutting (perfect for scratching).
Release the crossfader curve button to make the curve gradual
and gentle. The CROSSFADER REVERSE BUTTON (25) allows you to
reverse the crossfader so that CHANNEL 2 is controlled by the left
side of the crossfader and CHANNEL 1 is controlled by the right side
of the crossfader.

TE: When the

(25) (25)
(25) is activated (depressed), only the crossfader
(25) (25)
reverses. The Channel Slides and Gain do not reverse.
5. PUNCH IN: The PUNCH IN BUTTONS (16, 32) allow you to add a
channel’s signal to the mix when the crossfader is set to the opposite
channel.
6. OUTPUT CONTROL SECTION: The level of the MASTER OUTPUT (3) is
controlled by the MASTER (31) control. The BALANCE (30) control
will allow the MASTER OUTPUT signal to be balanced between the left
and right speakers.
NOTENOTE
NOTE: The
NOTENOTE
level is set by the channel slides and the gain controls of
the selected channel. The tonal qualities are set by the
low, mid and high controls of that same channel.
7. 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. The MIC/TALKOVER SWITCH (12) has three settings.
When the MIC/TALKOVER SWITCH (12) is in the bottom position, the
mic and talkover are both off. When the MIC/TALKOVER SWITCH
(12) is in the center position the mic is on, the MIC INDICATOR (13)

is in the top position, the mic and talkover will be on and the volume of
all sources except the Mic input are lowered by 16 dB. MIC LEVEL
(14) controls the level of the MIC.
8. CUE SECTION: By connecting a set of headphones to the HEADPHONE
(33) jack, you can monitor either CHANNEL 1 or CHANNEL 2. Move the
CUE SWITCH (24) to the left to monitor CHANNEL 1. Move the CUE
SWITCH (24) to the right to monitor CHANNEL 2. Use the CUE LEVEL
(5) control to adjust the headphone volume without effecting the
overall mix.
9. DISPLAY: The dual function DISPLAY (22) indicates either the
MASTER OUTPUT (3, 4) left and right levels or the CHANNEL 1 and
CHANNEL 2 input levels. You can choose the option you want by
pressing the DISPLAY (23) button.
