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.

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: Y ou 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 CROSSF ADER (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.

Connections

1. Make sure that the POWER (6) switch is in the OFF position. This unit comes supplied with a 15 volt AC adaptor. Plug the male pin of the adaptor into the rear panel POWER JACK (7). Then plug the adaptor into a proper power source.

2. The MASTER OUTPUT (1) jacks are unbalanced and used to connect to your main amplifier.

3. The DJ MIC (18) input (found on the front panel) accepts a 1/4" connector and balanced and unbalanced microphones.

4. 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, 10) enable you to set the (3, 4) 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 HEADPHONE (36) jack.

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.

NOTE: When the CROSSFADER REVERSE SWITCH (26) is activated (moved to the right), only the crossfader

reverses. The Channel Slides, Gain, Kill Switches and tonal 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

Page 4

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 HEADPHONE

(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.
