EX-26

Congratulations on purchasing the Gemini EX-26 mixer!
This state of the art mixer is backed by a three-year
warranty, excluding crossfader and channel slides. We
know you’re anxious to hook everything up and start mixing
beats and cranking up the volume on those hot dance
tracks, but we suggest reading this instruction manual first
as there are really cool features on this mixer that we
wouldn’t want you to miss!
The EX-26 Mixer features a crossfader which controls a
super-quiet photo coupler to give you smooth operation and
the cleanest possible sound, along with a "hamster" switch
that is easily accessible on the front of the mixer. This
“hamster” switch reverses the direction of the main
crossfader. This mixer also features individual “hamster”
switches for the separate channel input faders as well.
For additional information, refer to the diagrams on pages 1
& 2 for crossfader adjustment and channel slide curve.

INTRODUCTION
FEATURES
4. Do not expose this unit to direct sunlight or to a heat
source such as a radiator or stove.
5. This unit should be cleaned only with a damp cloth.
Avoid solvents or other cleaning detergents.
6. When moving this equipment, it should be placed in its
original carton and packaging. This will reduce the risk of
damage during transit.
7. Do not expose this unit to rain or moisture.
8. Do not use any spray cleaner or lubricant on any controls
or switches.
Okay, let’s hook everything up!
1. Make sure that the POWER
(1)
switch is in the “OFF”
position. This unit comes supplied with a 15 volt AC
adaptor. Plug the adaptor into the rear panel power jack.
Then plug the adaptor into your power strip or outlet.
2. The EX-26 mixer is supplied with 3 sets of output jacks.
The BALANCED MASTER OUTPUT
(2)
jacks are used to
connect to your main amplifier using standard cables with
1/4” connectors. We recommend using the balanced amp
outputs if the cables to your amp are 25 feet or more.
BALANCED MASTER OUTPUTS have three separate
conductors, two of which are signal (positive and negative)
and one shield (ground). The balanced line uses a tip-ring-
sleeve connection. Tip = hot or positive (+), ring = cold or
negative (-), and sleeve = shield/ground.
The MASTER OUTPUT
(3)
jacks are unbalanced and are
also used to connect to your main amplifier. The REC
OUTPUT
(4)
jacks can be used to connect the mixer to the
record input of your recorder enabling you to record your
mix.
CAUTIONS

CONNECTIONS

Pa
g
e 2
3. On the rear panel are 2 stereo LINE
(5,6)
inputs and
2 stereo PHONO
(7,8)
inputs. The phono inputs will accept
only turntables with a magnetic cartridge. GROUND
SCREWS (9) for you to ground your turntables are located
on the rear panel. The stereo line inputs will accept any line
level input such as a CD player, cassette player, etc.
4. Headphones can be plugged into the front panel
mounted PHONES (10) jack.
1. POWER ON: Once you have made all the equipment
connections to your mixer, press the POWER (1) switch.
2. CHANNEL 1: The GAIN
(11),
HIGH
(12),
MID
(13),
and
LOW
(14)
controls allow you to fully adjust the volume and
EQ of the sound source. The Channel 1 REVERSE
SWITCH
(15)
allows you to reverse the direction of the
Channel 1 slide fader.
(17)
The Channel 1 SLIDE FADER
(
17)
controls the input level of this channel.
3. CHANNEL 2: The GAIN
(11),
HIGH
(12),
MID
(13),
and
LOW
(14)
controls allow you to fully adjust the volume and
EQ of the sound source. The Channel 2 REVERSE
SWITCH
(16)
allows you to reverse the direction of the
Channel 2 slide fader.
(18 )
The Channel 2 SLIDE FADER
(
18 )
controls the input level of this channel.
4. EQ CONTROLS: There is Low, Mid and High
equalization for each channel with an extremely wide range
of adjustment.
5. INPUT ASSIGN SWITCHES: You can adjust the position
of the INPUT ASSIGN SWITCHES
(21, 22)
to move left to
right, up and down, or at a 45 degree angle.
Make these adjustments with the power OFF.
1) Remove the channel slide knobs, crossfader knobs and
the 4 screws from the sides of the lower faceplate. Then
remove the lower faceplate.
2) Remove the 2 screws in the corners of the assign switch
plate. Rotate the switch plate to the desired position, and
replace the screws and tighten down.
3) To position the switch at a 45-degree angle, you need to
reposition the switch on the assign switch plate. First,
remove the 2 screws in the corners of the assign switch
plate. Then, lift the switch plate up and remove the 2
smaller screws next to the switch. Rotate the switch plate to
the right until the 45-degree holes align with the switch
holes, replace the screws and tighten down. Replace the
switch plate and tighten down.
NOTE: Keep track of where you position the input
assign switches.
OPERATION
6. CHANNEL SLIDE CURVE SWITCHES: Use the 3
position CHANNEL SLIDE CURVE SWITCHES (23,24) to
adjust the kind of curve the channel slides have. Move the
selected channel slide curve switch to the 6 (top) position to
make the increase in level gradual and even. Move the
channel slide curve switch to the 20 (center) position to
make the increase in level less gradual as you move
channel slide up. Move the channel slide curve switch to
the 30 (bottom) position to make the increase in level even
less gradual, especially at the top of the slide.
7. CROSSFADER SECTION: The CROSSFADER (25)
allows the mixing of one source into another. The left side
of the CROSSFADER (25) is CHANNEL 1 and the right
side is CHANNEL 2. The CROSSFADER CURVE
CONTROL (26) allows you to adjust the kind of curve the
crossfader has. Move the CROSSFADER CURVE
CONTROL (26) to the right to make the curve steep and
cutting (perfect for scratching). Move the CROSSFADER
CURVE CONTROL(26) to the left to make the curve
gradual and gentle. The CROSSFADER REVERSE
BUTTON (27) 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. When REVERSE is activated the REVERSE
LED (28) will light.
NOTE: When the CROSSFADER REVERSE BUTTON is
activated (depressed), only the crossfader reverses.
The Channel Slides, Gain,
and EQ controls do not
reverse.
8. OUTPUT CONTROL SECTION: The level of the
MASTER OUTPUT (2, 3) is controlled by the MASTER
CONTROL (20). The BALANCE CONTROL KNOB (19)
controls the balance between the output of the left and right
channels.
NOTE: The RECORD OUT (4) has no level control. The
level is set by the channel slides and the gain controls
of the selected channel. The EQ of the channels is set
by the low, mid and high controls of that same channel.
9. CUE SECTION: By connecting a set of headphones to
the PHONES JACK
(10)
, you can monitor the music
coming out of each channel separately or both channels
together. Move the CUE FADER (29) to the left to hear
CHANNEL 1 and to the right to hear CHANNEL 2. Move
the CUE FADER (29) to the center to listen to both
channels together. The PHONES MUTE BUTTON
(30)
will
instantly mute your cue mix.
10. DISPLAY: The red LED in the center of the display tells
you that the power in your EX-26 Mixer is on.
The multi-colored LED DISPLAY
(31)
on either side of the
center tells you the output level of your 2 channels.
Okay, that’s it! NOW you’re ready to grab a couple of great
CD’s or records, crank it up and get the party started!
