Precautions
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 PARTS INSIDE. Please contact the
Gemini Service Department or your authorized dealer to speak to a
qualified service technician.
In the U.S.A., if you have any problems with this unit, call
1-732-969-9000 for customer service. Do not return
equipment to your dealer.
3. Tone arm bearings are factory set and sealed. Any attempt at adjust-
ment will void the warranty.
4. Be sure that all AC power is OFF while making connections.
5. Cables should be low capacitance, shielded and of proper length. Make
sure that all plugs and jacks are tight and properly connected.
6. Always begin with the audio level faders/volume controls set at
minimum and the speaker volume control(s) set to OFF. Wait 8 to 10
seconds prior to turning up the speaker volume to prevent the transient
"POP" that could result in speaker/crossover damage.

Assembly and Set-Up
NOTE: SEE FIG. 1 (PAGE 1) FOR PART NUMBERS AND
LOCATIONS.
TURNTABLE INSTALLATION:
1. Set the TURNTABLE BASE (1) on a flat, level surface free of vibration.
Try to place the unit as far away from the speakers as possible. Keep
the unit away from direct exposure to the sun, heat, moisture or dirt.
Keep the unit well ventilated. Use the turntable feet to horizontally
stabilize the unit.
2. Make sure that the VOLTAGE SELECTOR (3) switch (located on the
TURNTABLE BASE) is set to the correct voltage. WARNING: If you try
to operate the turntable with the incorrect voltage setting, it can damage
your turntable.
3. After checking to ensure that all packing materials have been removed,
gently place the PLATTER (2) on the center spindle of the TURNTABLE
BASE (1).
4. Put the NEOPRENE MAT (4) on the PLATTER (2).
CARTRIDGE INSTALLATION: (SEE FIG. 2)
Because all cartridges have their own designs, please refer to your
particular cartridge's instructions to insure proper installation.
1. Connect the lead wires to the cartridge terminals. For your convenience,
the terminals of most cartridges are color coded. Connect each lead
wire to the terminal of the same color.
White (L+).............................................Left Channel +
Blue (L-)...............................................Left Channel -
Red (R+)................................................Right Channel +
Green (R-).............................................Right Channel -
2. Mount the cartridge in the HEADSHELL (5) and tighten it with the
screws included with the cartridge.
ATTENTION STANTON 680 CARTRIDGE USERS
When using a Stanton 680 or similar cartridge, where the body is
grounded to a cartridge terminal, remove the grounding strap from
the cartridge body to the cartridge ground terminal. Failure to do this
may result in excessive hum.
HEADSHELL INSTALLATION:
Insert the HEADSHELL (5) into the front of the tubular TONE ARM (6).
While holding the HEADSHELL firmly in a horizontal position, turn the
LOCKING NUT (7) counter clockwise until the HEADSHELL is locked in
place.
COUNTERWEIGHT INSTALLATION: (SEE FIG. 3)
1. Slide the COUNTERWEIGHT (8) onto the rear of the TONE ARM (6)
with the numbered stylus gauge facing forward.
2. Twist the COUNTERWEIGHT (8) lightly counter clockwise, to screw it
onto the rear of the TONE ARM (6).
ADJUSTING HORIZONTAL ZERO (0) BALANCE AND
STYLUS PRESSURE:
1. Without touching the stylus tip, remove the stylus protector (if your
cartridge has a detachable one).
2. Release the ARM CLAMP (9) and lift the TONE ARM (6) off the ARM
REST (10).
3. Counter clockwise advancement of the COUNTERWEIGHT (8) will
cause the cartridge side of the TONE ARM (6) to be lowered. Clockwise
will cause the opposite. Turn the COUNTERWEIGHT clockwise or
counter clockwise as needed until the TONE ARM is balanced horizon-
tally. You can easily tell this by watching for the point where the TONE
ARM "floats" freely.
4. Place TONE ARM (6) on ARM REST (10) and lock it in place with the
ARM CLAMP (9).
5. With the TONE ARM (6) locked on the ARM REST (10), hold the
COUNTERWEIGHT (8) steady with one hand while rotating the
STYLUS PRESSURE RING (11) until the numeral "0" on the ring aligns
with the center line on the TONE ARM rear shaft. The horizontal zero
(0) balance should be completed.
6. Refloat the TONE ARM to ensure horizontal zero (0) balance. If zero
balance has not been maintained, repeat counterweight steps 3 - 5.
7. After adjusting the horizontal zero (0) balance, turn the balanced
COUNTERWEIGHT (8) counter clockwise until the cartridge
manufacturer's recommend stylus pressure appears on the STYLUS
PRESSURE RING (11) where it meets the center line of the TONE ARM
(6) rear shaft.
ADJUSTING THE ANTI-SKATING CONTROL:
Set the ANTI-SKATING CONTROL (12) to the same value as the stylus
pressure.
