PHONO/LINE (3, 4)
inputs, 1 stereo
PHONO (5)
input and 1 stereo
LINE (2)
input. The
PHONO/LINE
SWITCHES (8, 10)
enable you to set the

inputs to Phono or Line.
The phono inputs will accept only turntables with a magnetic cartridge.
A
GROUND SCREW (9)
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

(36)
jack.
Operation
1. POWER ON: Once you have made all the equipment connections to
your mixer, press the
POWER (6)
switch. The power will turn on and
the
POWER LED (23)
will glow RED.
2. CHANNEL 1: The
GAIN (11)
,
HIGH (12)
,
MID (13)
,
and
LOW (14)
controls allow you to fully adjust the selected source. Switch #
(15)
allows you to select either the
PHONO 1 (5)
or the
PHONO 2/LINE 1
(4)
input. The
CHANNEL SLIDE (16)
controls the output level of this
channel.
3. CHANNEL 2: The
GAIN (29)
,
HIGH (30)
,
MID (31)
,
and
LOW (32)
controls allow you to fully adjust the selected source. Switch #
(33)
allows you to select either the
PHONO 3/LINE 2 (3)
or the
LINE 3 (2)
input. The
CHANNEL SLIDE
(34)
controls the output level of this
channel.
4. KILLING LOW FREQUENCIES: You can use the Kill Feature on each
channel to remove Low band frequencies to create special effects
and improve your mix. Move the
KILL SWITCH (17)
down to remove
the low band of Channel 1 from your mix. Move the
KILL SWITCH
(35)
down to remove the low band of Channel 2 from your mix.
5. CROSSFADER SECTION: The
CROSSFADER (27)
allows the mixing of
one source into another. The left side of the
CROSSFADER (27)
is
CHANNEL 1 and the right side is CHANNEL 2. The
CROSSFADER (27)
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 SWITCH (28)
allows you to adjust the kind
of curve the crossfader has. When the switch is in the left position,
the curve is gradual and gentle. When the switch is in the right
position, the curve is steep and cutting (perfect for scratching). The
CROSSFADER REVERSE SWITCH (26)
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.

controls do not reverse.
6. OUTPUT CONTROL SECTION: The level of the
MASTER OUTPUT (1)
is
controlled by the
MASTER (21)
control.
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 (19)
switch
has three settings. When
the
MIC/TALKOVER (19)
switch is in the left position, the mic and
talkover are both off. When the
MIC/TALKOVER (19)
switch is in the
center position the mic is on, the
MIC INDICATOR
will glow, but
talkover is off. When the
MIC/TALKOVER (19)
switch is in the right
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 (20)
controls
the level of the MIC.
8. CUE SECTION: By connecting a set of headphones to the
PHONES
(36)
jack, you can monitor either channel or both together. Move the
CUE SWITCH (25)
to the left to monitor CHANNEL 1. Move the
CUE
SWITCH (25)
to the right to monitor CHANNEL 2. Move the
CUE
SWITCH (25)
to the center position to split the signals from each
channel so that CHANNEL 1 will be heard in one earphone and
CHANNEL 2 will be heard in the other earphone. Use the
CUE LEVEL
(22)
control to adjust the headphone volume without effecting the
overall mix.
9. DISPLAY: The
DISPLAY (24)
indicates the
MASTER
output.
