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.

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.

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.

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).

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.

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.
