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 1-732-738-9003 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. Before plugging in the power cord, make sure that the VOLTAGE
SELECTOR (33) switch is set to the correct voltage.
2. Make sure that the POWER (1) switch is in the off position. The
POWER LED (2) will be off.
3. The KL-10 is supplied with 3 sets of output jacks. The OUTPUT
AMP (34) jacks are used to connect to your main amplifier. The
OUTPUT REC (36) jacks can be used to connect the mixer to the
record input of your recorder enabling you to record your mix. The
OUTPUT BOOTH (35) jacks allow you to hook up an additional
amplifier.
4. The DJ MIC (3) input (found on the front panel) accepts a 1/4" or
XLR connector and balanced and unbalanced microphones.
5. On the rear panel are 2 stereo PHONO/LINE (40, 42) inputs and 2
stereo LINE (39, 41) inputs. The PHONO/LINE SWITCHES (43, 44)
enable you to set the (40, 42) inputs to Phono or Line. The phono
inputs will accept only turntables with a magnetic cartridge. A
GROUND SCREW (45) 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.
6. Headphones can be plugged into the front panel mounted
HEADPHONE (9) jack.
7. There are LOOP INPUTS (37) and LOOP OUTPUTS (38) located on
the rear panel. If you are using an outboard signal enhancer, you
can use the LOOP OUTPUTS (38) to send the signal to the device
and the LOOP INPUTS (37) to bring the signal back in to the mixer.
The unit comes with jumpers to be used with the loop inputs and
outputs. Keep the jumpers in the unit if you are not using the loop to
prevent interruptions in your music program by the accidental
touching of the loop button.
Using the Ground Lift Switch
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.
1. With the mixer on, listen to the system in idle mode (no signal
present) with the ground applied (the GROUND LIFT SWITCH (46) in
the bottom position).
2. Then turn the power off before moving the GROUND LIFT
SWITCH (46). Lift the ground by moving the GROUND LIFT SWITCH
to the top position, 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.
CAUTION: DO NOT TERMINATE THE AC GROUND ON THE POWER MIXER
IN ANY WA Y. TERMINA TION OF THE AC GROUND CAN BE
HAZARDOUS.
Operation
1. POWER ON: Once you have made all the equipment connections to
your mixer, press the POWER SWITCH (1). The power will turn on
and the POWER LED (2) will glow RED.
2. CHANNEL I: The GAIN (10), BALANCE (11), HIGH (18), MID (17),
and LOW (16) controls allow you to fully adjust the selected source.
Switch # (12) allows you to select either the PHONO 1/LINE 1 (42)
or the LINE 2 (41) input. The CHANNEL SLIDE (14) controls the
output level of this channel.
3. CHANNEL II: The GAIN (10), BALANCE (11), HIGH (18), MID (17),
and LOW (16) controls allow you to fully adjust the selected source.
Switch # (13) allows you to select either the PHONO 2/LINE 3 (40)
or the LINE 4 (39) input. The CHANNEL SLIDE (15) controls the
output level of this channel.
4. CROSSFADER SECTION: The CROSSFADER (19) allows the mixing
of one source into another. The left side of the CROSSFADER (19) is
channel I and the right side is channel II. The CROSSFADER (19) 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:
Page 4
1. Unscrew the outside FADER PLA TE 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.
5. KILLING FREQUENCIES: There are two ways to kill frequencies,
using the LOW, MID and HIGH KILL SWITCHES (20, 21, 22) and
using the LOW, MID and HIGH ROTARY CONTROLS (16, 17, 18).
When the selected KILL SWITCH is activated the LED will light and
the frequency will be killed. When the selected ROTARY CONTROL
is turned all the way to the left, the frequency will be killed. You can
also use the ROTARY CONTROLS to boost frequencies up to +12
dB. The normal setting for the ROTARY CONTROLS is zero.
SUGGESTION: You can use the Kill Features on each channel to
remove Low, Mid and/or High bands for a smoother mix and mix
frequencies from both channels to create special effects.
6. PUNCH IN: The PUNCH IN BUTTON (23) allows you to add a
channel’s signal to the mix when the crossfader is set to the
opposite channel.
7. PUNCH OUT: The PUNCH OUT BUTTON (24) allows you to remove a
channel’s signal from the mix when the crossfader is set to that
channel.
SUGGESTION: Keep the crossfader in the center and use the
punch in and punch out of both channels together to create
scratch type effects.
8. LOOP SECTION: T o activate loop, press the LOOP BUTTON (25) and
the LOOP LED (26) will light. When the LOOP LED is lit, any device
connected to the LOOP OUTPUT (38) and INPUT (37) jacks will be
inserted into the signal path.
9. OUTPUT CONTROL SECTION: The level of the AMP OUT (34) is
controlled by the MASTER (27) control. The BOOTH (28) control
adjusts the level of the BOOTH OUTPUT (35). 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.
NOTE: The RECORD OUT (36) has no level control.
The level is set by the channel slides and the gain
controls of the selected channel. The tonal qualities are
set by the bass, treble and mid controls of that same
channel.
10. 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 (4) has three settings.
When the MIC/TALKOVER SWITCH (4) is in the bottom position, the
mic and talkover are both off. When the MIC/TALKOVER SWITCH
(4) is in the center position the mic is on, the MIC INDICATOR (5) will
glow, but talkover is off. When the MIC/TALKOVER SWITCH (4) 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. The TREBLE
(6), BASS (7), and LEVEL (8) controls allow you to fully adjust the
mic signal.
11. CUE SECTION: By connecting a set of headphones to the
HEADPHONE (9) jack, you can monitor either channel or both. Select
the Channel I by sliding the CUE SLIDER (29) control to the left or
Channel II by sliding the CUE SLIDER (29) control to the right. Use
the CUE LEVEL (30) control to adjust the headphone volume without
effecting the overall mix.

12.DISPLAY: The dual function DISPLAY (31) indicates either the
MASTER OUTPUT (34) left and right levels or the channel I and
channel II levels. You can choose the option you want by pressing
the DISPLAY (32) button.
NOTE: When the DISPLAY (31) is in the channel I/
channel II display mode, by adjusting the individual
channel gain and tone controls, you can increase or
decrease the signal to match the other channels signal.
The channel slides and crossfader have no effect on the
display readings.
