INTRODUCTION:

Congratulations on your purchase of the Gemini PS-700i or PS-900i

CAUTIONS:

1. Read all operating instructions before using this equipment.

2. To reduce the risk of electrical shock, do not open the unit. THERE ARE
NO USER REPLACEABLE P ARTS INSIDE. Please refer all unit servicing
to a qualified Gemini Sound Products service technician.

In the USA: If you experience problems with this unit, please call 1 [phone] for Gemini

Customer Service. Do not attempt to return this equipment to your dealer.

3. Do not expose this unit to direct sunlight or to heat sources such
as a radiator or stove.

4. This unit should be cleaned with a damp cloth ONLY. Avoid solvents
and other cleaning detergents. Do not use spray cleaner or lubricant
on controls or switches.

5. When moving this equipment, it should be placed in its original carton
and packaging to reduce the risk of damage during transit.

6. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.

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/900i is 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. T urn 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™) DUAL­RAIL 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/700i features 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.
