Cut Feature for Low, Mid and High of each channel
3 Stereo channels (3 Phono, 3 Line and 1 Mic)
1/4" DJ Mic jack
Using the Ground Lift Switch
Low, Mid, High and Gain controls on each channel
Beat indicators
Depending on your system configuration, sometimes applying the
ground will create a quieter signal path. Sometimes lifting the ground
can eliminate ground loops and hum to create a quieter signal path.
12 volt BNC light jack
1. With the mixer on, listen to the system in idle mode (no signal
present) with the ground applied (the GROUND LIFT SWITCH (41)
in the left position).
Master, Booth and Record outputs
Dual mode display (Left & Right output or Channel 2 and Channel 3)
Push button cueing with Cue/Program pan control
2. Then turn the power off before moving the GROUND LIFT
SWITCH (41). Lift the ground by moving the GROUND LIFT SWITCH
to the right, turn the power back on and listen to determine which
position will provide a signal devoid of background noise and hum.
Keep the GROUND LIFT SWITCH in the ground position if the noise
level remains the same in either position.
Cautions
1. All operating instructions should be read before using this
equipment.
CAUTION: DO NOT TERMINATE THE AC GROUND ON THE POWER
MIXER IN ANY WAY. TERMINATION OF THE AC GROUND CAN BE
HAZARDOUS.
2. To reduce the risk of electrical shock, do not open the unit. There
are NO USER REPLACEABLE PARTS INSIDE. Please refer servicing

and the POWER LED (2) will glow RED.
3. Do not expose this unit to direct sunlight or to a heat source such as
a radiator or stove.
2. CHANNEL 1: The GAIN (6), HIGH (7), MID (8), and LOW (9),
controls allows you to fully adjust the selected source. Switch #
(10) allows you to select either the mic or the PHONO/LINE (36)
input. The CHANNEL (13) slide controls the output level of this
channel.
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.
3. MAIN CHANNEL SECTION: To assign an input source to a channel,
first set the PHONO/LINE (11,12) switches to their appropriate
positions. To make the proper adjustments to your music, set the
GAIN (6), HIGH (7), MID (8) and LOW (9) controls and position the
CHANNEL (14, 15) slide.
7. DO NOT USE ANY SPRAY CLEANER OR LUBRICANT ON ANY
CONTROLS OR SWITCHES.
NOTE: There is Low, Mid and High equalization for each
channel with an extremely wide range of adjustment
giving you a smoother mix.
Connections
1. Before plugging in the power cord, make sure that the VOLTAGE
SELECTOR (30) switch is set to the correct voltage.
SUGGESTION: You can use the Cut Features on each channel to
remove Low, Mid and/or High to create special effects.
NOTE: This product is double insulated and not intended
4. CROSSFADER SECTION: The CROSSFADER (25) allows the mixing
of one source into another. The left side of the CROSSFADER (25) is
channel 2 and the right side is channel 3. The CROSSFADER (25) 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:
to be grounded.
2. Make sure that the POWER (1) switch is in the off position. The
POWER LED (2) will be off.
3. The PS-626 PRO2 is supplied with 3 sets of output jacks. The
OUTPUT AMP (38) jacks are used to connect to your main amplifier.
The OUTPUT REC (40) jacks can be used to connect the mixer to
the record input of your recorder enabling you to record your mix.
The OUTPUT BOOTH (39) jacks allow you to hook up an additional
amplifier.
4. The DJ MIC (3) input (found on the front panel) accepts a 1/4"
connector and accepts only unbalanced microphones.

BOOTH OUTPUT (39). HINT: The booth OUTPUT is used by some
DJs to run monitor speakers in their DJ booth. You can also use it as
a second ZONE or AMP output.

controls of the selected channel. The tonal qualities are
set by the bass, treble and mid controls of that same
channel.

HEADPHONE (4) jack, you can monitor any or all of the channels.
Select the correct CUE (21) button or buttons and their respective
CUE LED (29) indicators will glow. Use the CUE LEVEL (20) control
to adjust the headphone volume without effecting the overall mix. By
sliding the CUE PGM PAN (22) control to the left you will be able to
monitor the assigned cue signal. Sliding to the right will monitor the
PGM (program) output.
9. DISPLAY: The peak hold, dual function DISPLAY (26) indicates either
the MASTER (38) output left and right levels or the channel 2 and
channel 3 levels. You can choose the option you want by pressing
the DISPLAY (27) button.
NOTE: When the DISPLAY (27) is in the channel 2/
channel 3 display mode, by adjusting the individual
channel gain and tone controls, you can increase or
decrease the signal to match the other channel’s signal.
The channel slides and crossfader have no effect on the
display readings.
