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.
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 (22) switch is in the off position.
2. This unit comes supplied with a 15 volt AC adaptor. Plug the male pin
of the adaptor into the rear panel POWER JACK (6). Then plug the
adaptor into a proper power source.
3. To connect the mixer to your amplifier, use the OUTPUT AMP (1) jacks
on the rear panel.
4. The unit is equipped with one microphone input. The MIC JACK (15)
is a 1/4" (6.35 mm) and is located on the front panel.
5. On the rear panel are 2 stereo PHONO/LINE (3, 4) inputs, 1 stereo
PHONO (5) input and 1 stereo LINE (2) input. The PHONO/LINE
SWITCHES (8, 9) enable you to set the (3, 4) inputs to Phono or Line.
The PHONO (5) input will accept turntable inputs only. A GROUND (7)
screw for you to ground your turntables is located on the rear panel.
The stereo LINE (2) input will accept any line level input like a CD
player or a cassette player.
6. Headphones can be plugged into the front panel mounted
HEADPHONE (26) jack.
Operation
1. POWER ON: Once you have made all the equipment connections to
your mixer, press the POWER (22) switch. The power will turn on and
the POWER LED (21) will glow RED.
2. CHANNEL 1: The GAIN (12) control allows you to individually adjust
the gain of the channel. Switch # (13) allows you to select the PHONO
1 (5) or the LINE 1/PHONO 2 (4) input. The CHANNEL SLIDE (14)
controls the input level of this channel.
3. CHANNEL 2: The GAIN (23) control allows you to individually adjust
the gain of the channel. Switch # (24) allows you to select the LINE 2/
PHONO 3 (3) or the LINE 3 (2) input. The CHANNEL SLIDE (25)
controls the input level of this channel.
4. CROSSFADER SECTION: The CROSSFADER (20) allows the mixing
of one source into another. The left side of the CROSSFADER (20) is
CHANNEL 1 and the right side is CHANNEL 2. The CROSSFADER
(20) 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.
5. 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. When the TALKOVER (11) button is pushed, the
TALKOVER INDICATOR (10) will glow and the volume of all sources
except the Mic are reduced by -16 dB. LEVEL (17) controls the level of
the MIC.
6. CUE SECTION: By connecting a set of headphones to the
HEADPHONE (26) jack, you can monitor either channel 1 or channel
2. Select Channel 1 by moving the CUE SWITCH (19) to the left or
Channel 2 by moving the CUE SWITCH (19) to the right. Use the CUE
LEVEL (18) control to adjust the headphone volume without effecting
the overall mix.
7. DISPLAY: The DISPLAY (16) indicates the MASTER output left and
right levels.
