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
adjustment 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.
7. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
8. DO NOT USE ANY SPRAY CLEANER OR LUBRICANT ON ANY
CONTROLS OR SWITCHES.

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 C
Blue (L-)...................................................Left Channel -
Red (R+).................................................Right C
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 (6)
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.
