CONNECTIONS:

1.Before plugging in the power cord, make sure that the VOLTAGE SELECTOR (46) switch is set to the correct voltage.

NOTE: THIS PRODUCT IS DOUBLE INSULATED AND IS NOT INTENDED TO BE GROUNDED.

2.Make sure that the POWER (41) switch is in the OFF position. The POWER LED (42) will be OFF.

3.The PS-700i/900iis supplied with 4 sets of output jacks. The XLR BALANCED OUTPUT (48) jacks are used to connect to your main amplifier using standard XLR cables. We recommend using balanced amp outputs if the cables to your amp are 25 feet or more. XLR BALANCED OUTPUTS have three separate conductors, two of which are signal (positive and negative) and one shield (ground). Pin 1 is ground (shield). Pin 2 is signal hot (positive). Pin 3 is signal cold (negative). The MAIN OUTPUT (49) (RCA type) jacks are unbalanced and used to connect to your main amplifier. The REC OUTPUT (51) (RCA type) jacks can be used to connect the mixer to the record input of your recorder enabling you to record your mix. The BOOTH OUTPUT (50) (RCA type) jacks allow you to hook up an additional amplifier.

4.The MIC 1 (1) input (found on the front panel) accepts XLR & 1/4” connectors. The MIC 2 (66) input and the MIC 3 (65) input (found on the rear panel) accept 1/4" connectors. All accept balanced and unbalanced microphones.

5.On the rear panel are 3 stereo PHONO/LINE (57, 60, 63) inputs and 5 stereo LINE (54, 55, 56, 59, 62) inputs. The PHONO/LINE SWITCH (58) enables you to set the (57) input to Phono or Line. The PHONO/LINE SWITCH (61) enables you to set the (60) input to Phono or Line. The PHONO/LINE SWITCH (64) enables you to set the (63) input to Phono or Line. The phono inputs will accept only turntables with a magnetic cartridge.

6.A turntable GROUND SCREW (67) is located on the rear panel.

7.Headphones can be plugged into the front panel mounted HEADPHONE JACK (45) .

8.The PS-700i/900i features a front panel BNC LIGHT JACK (40). This jack is for a gooseneck lamp such as the Gemini GNL-700.

9.There are LOOP INPUTS (53) and LOOP OUTPUTS (52) located on

the rear panel. If you are using an outboard signal processor, you can use the LOOP OUTPUTS (52) to send the signal to the device and the LOOP INPUTS (53) 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.

THE GROUND LIFT SWITCH:

Depending on your system configuration, applying the ground sometimes creates a quieter signal path. Sometimes “lifting” the ground eliminates loops and hum to create a quieter signal path.

1.Listen to the system with the unit ON, without music, and with the ground “applied”. GROUND LIFT SWITCH (68) should be to the left.

2.Turn power OFF before moving the GROUND LIFT SWITCH.

3.Now, “lift” the ground by moving the GROUND LIFT SWITCH to the right. Turn the power back ON and listen to determine which position provides a signal free of background noise and hum.

NOTE: KEEP GROUND LIFT IN THE GROUND “APPLIED” OR LEFT POSITION IF NOISE LEVEL REMAINS THE SAME IN EITHER POSITION.

CAUTION: DO NOT TERMINATE THE AC GROUND ON THE POWER CABLE. TERMINATION 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 (41). The power will turn on and the POWER LED (42) will “glow” RED.

2.CHANNEL 1: The GAIN (9), HIGH (10), MID (11), and LOW (12) controls allow you to fully adjust the selected source. Switch (13) allows you to select the PHONO 1/LINE 1 (63) or the LINE 2 (62) input. CHANNEL SLIDE (14) controls the input level of this channel.

3.CHANNEL 2: The GAIN (9), HIGH (10), MID (11), and LOW (12) controls allow you to fully adjust the selected source. Switch (15) allows you to select the PHONO 2/LINE 3 (60) or the LINE 4 (59) input. CHANNEL SLIDE (16) controls the input level of this channel.

4.CHANNEL 3: The GAIN (9), HIGH (10), MID (11), and LOW (12) controls allow you to fully adjust the selected source. Switch (17) allows you to select the PHONO 3/LINE 5 (57) or the LINE 6 (56) input. CHANNEL SLIDE (18) controls the input level of this channel.

5.CHANNEL 4: The GAIN (9), HIGH (10), MID (11), and LOW (12) controls allow you to fully adjust the selected source. Switch (19) allows you to select the LINE 7 (55), LINE 8 (54) or the MIC 3 (65) input. CHANNEL SLIDE (20) controls the input level of this channel.

PLEASE NOTE: THERE IS LOW, MID AND HIGH EQUALIZATION FOR EACH CHANNEL WITH AN EXTREMELY WIDE RANGE OF ADJUSTMENT.

SUGGESTION: YOU CAN USE THE CUT FEATURES ON EACH CHANNEL TO REMOVE LOW, MID AND/OR HIGH RANGE TO CREATE SPECIAL EFFECTS.

Your Gemini mixer comes with an RG-45 PRO (RAIL GLIDE™) DUAL- RAIL CROSSFADER. Rail Glide™ Crossfaders have internal dual stainless steel rails that allow the slider to ride smoothly and accurately from end to end. Note: Gemini replacement Crossfaders are available in three varieties: the RG-45 PRO (RAIL GLIDE™) Dual-Rail Crossfader ; the RF-45, which has a 45 mm travel from side-to-side; and the PSF-45, which features a special “curve” designed for scratch mixing. The Crossfader in your unit is removable and, should the need arise, can easily be replaced by following these instructions.

1.Unscrew the outside FADER plate screws (B). - Do not touch INSIDE SCREWS (C).

2.Carefully remove old Crossfader and unplug CABLE (D).

3.Plug new Crossfader into CABLE (D)

and place back into mixer.

4.Screw Crossfader to mixer with

FADER PLATE SCREWS (B).

6.CROSSFADER: The CROSSFADER (22) allows the mixing of one source into another. The PS-900i/700ifeatures an assignable Rail Glide™ Crossfader. The ASSIGN (21, 23) switches allow you to select which channel will play through each side of the crossfader. The ASSIGN (21) switch has 5 settings (OFF, 1, 2, 3 or 4) and allows you to select channel 1, 2, 3 or 4 to play through the left side of the crossfader. The ASSIGN (23) switch has 5 settings (OFF, 1, 2, 3 or 4) and allows you to select Channel 1, 2, 3 or 4 to play through the right side of the crossfader. With the ASSIGN switch in the OFF position, that side of the crossfader will be inactive.

7.LOOP: Removing the jumpers from the LOOP OUTPUT (52) and INPUT (53) jacks will activate the loop. Any device connected to the LOOP OUTPUT (52) and INPUT (53) jacks will be inserted into the signal path.

HINT: BOOTH OUTPUT (50) IS USED BY SOME DJS TO RUN MONITOR SPEAKERS IN THE DJ BOOTH. YOU CAN ALSO USE IT AS A SECOND ZONE OR AMP OUTPUT.

NOTE: THE RECORD OUT (51) HAS NO LEVEL CONTROL. THE LEVEL IS SET BY THE CHANNEL SLIDES AND THE GAIN CONTROLS OF THE SELECTED CHANNEL. TONAL QUALITIES ARE SET BY THE LOW, MID AND HIGH CONTROLS OF THAT SAME CHANNEL.
