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 PAR TS INSIDE.
Please contact the Gemini Service Department or your
authorized dealer to speak to a qualified service technician.

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.

NOTE: SEE FIG. 1 ( PAGE 1 ) FOR PART NUMBERS AND

TURNT ABLE PLA TTER INST ALLA TION:

Set the TURNTABLE BASE (1) on a flat, level surface. 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) . Put the RUBBER MA T (3) on the
PLATTER (2).

CARTRIDGE INST ALLA TION:
(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 (4) 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.

1. Slide the COUNTERWEIGHT (7) onto the rear of the TONE
ARM (5).

2. Twist the COUNTERWEIGHT (7) lightly counterclockwise, to
screw it onto the rear of the TONE ARM (5)

.

ADJUSTING HORIZONT AL 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 (8) and lift the TONE ARM (5) off
the ARM REST (9).

3. Counter clockwise advancement of the COUNTERWEIGHT (7)
will cause the cartridge side of the TONE ARM (5) to be
lowered. Clockwise will cause the opposite. Turn the COUN-
TERWEIGHT clockwise or counter clockwise as needed until
the TONE ARM is balanced horizontally. You can easily tell this
by watching for the point where the TONE ARM “floats” freely.

4. Place TONE ARM (5) on ARM REST (9) and lock it in place
with the ARM CLAMP (8).

5. With the TONE ARM (5) locked on the ARM REST (9), hold the

COUNTERWEIGHT (7) steady with one hand while rotating the
STYLUS PRESSURE RING (10) until the numeral “0” on the ring

aligns with the center line on the TONE ARM (5) 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 (7) counter clockwise until the
cartridge manufacturer’s recommend stylus pressure appears
on the STYLUS PRESSURE RING (10) where it meets the
center line of the TONE ARM (5) rear shaft.

ADJUSTING THE ANTI-SKA TING
CONTROL:

Set the ANTI-SKATING CONTROL (11) to the same value as the
stylus pressure.

ADJUSTING TONE ARM HEIGHT :

The tone arm height is adjustable between 0 and 6 mm. A HEIGHT
SCALE (13) (in 0.5 mm increments) is provided to aid in an

accurate setting.

1. Unlock the tone arm by turning the ARM LOCK (14) knob
away from the lock position.

2. Look up the cartridge height on Table A and find its
corresponding height scale reading.

3. Turn the HEIGHT ADJUSTMENT RING (12) until the reference
line on the ring is positioned at the correct scale reading.

4. Lock the tone arm by turning the ARM LOCK (14) knob
clockwise until it reaches the lock position.

INST ALLING THE DUSTCOVER:

1. Hold the dustcover in position, directly above the turntable, and
slide the hinge bases into the holders mounted on the rear
panel.

2. Always raise the dustcover before removal.

3. Avoid opening and closing the dustcover during play.
Undesirable vibration and stylus skipping can result.

UNIT PLACEMENT :

1. Place unit on a flat, vibration free surface. Use the turntable
feet to horizontally stabilize the unit.

2. Try to place the unit as far away from the speakers as
possible.

3. Keep the unit away from direct exposure to the sun, heat,
moisture or dirt.

4. Keep the unit well ventilated.

CONNECTIONS:

1. Plug the AC power plug into an appropriate outlet.

2. See Table B for proper connection of the output RCA plugs and
ground connector. Make sure that all the plugs are firmly
plugged into the appropriate jacks. To reduce hum, make sure
the ground lug is firmly connected to the ground screw.

Operating Instructions

BASIC OPERA TION:

1. Place a record on the RUBBER MAT (3) which sits on the
PLATTER (2).

2. Select the desired speed by depressing the 33 or 45 SPEED
SELECTOR BUTTON (17).

3. Turn the POWER SWITCH (15) to the “ON” position, at which
point the strobe illuminator (built into the POWER SWITCH (15)
and the speed indicator (for the selected speed) will illuminate.

4. Remove the stylus protector (if applicable to your cartridge).

5. Release the ARM CLAMP (8) found on the ARM REST (9).

6. Push the START STOP BUTTON (16). The turntable PLATTER
(2) will start to spin.

7. Push the CUE LEVER (18) to the “UP” position.

8. Position the tone arm over the desired position on the record
and push the CUE LEVER to the “DOWN” position. The TONE
ARM (5) will slowly lower onto the record at which time play
will begin.

9. When play is over, raise the TONE ARM (5), move it to the
ARM REST (9), and secure it with the ARM CLAMP (8).

10. You now have the option of turning off the power by turning
the POWER SWITCH (15) to the “OFF” position, or stopping
the PLATTER (2) by pushing the START STOP BUTTON (16)
and engaging the electronic brake.

INTERRUPTING PLA Y :

1. Pushing the CUE LEVER (18) to the “UP” position will cause
the TONE ARM (5) to lift stopping play.

2. Pushing the CUE LEVER (18) to the “DOWN” position will
cause the TONE ARM (5) to slowly lower onto the record at
the point where play was interrupted.

PLA YING 45 RPM RECORDS:

1. When playing a 45 rpm record with a large center hole, first
place the 45 ADAPTOR (19) on the center spindle.

2. Be sure that the 45 SPEED SELECTOR BUTTON (17) is
pushed and the 45 speed indicator is illuminated.

T ARGET LIGHT :

1. Push the TARGET LIGHT SWITCH (20) firmly and the
TARGET LIGHT (21) will raise into position and illuminate the

stylus tip.

2. To lower the TARGET LIGHT, push down on it until it locks in
the casing.

3. When not being used, the TARGET LIGHT should be kept in
the lowered position.

XLR LAMP ADAPTOR:

1. Plug a gooseneck light with an XLR base, like the GEMINI GNL­500, into the XLR LAMP ADAPTOR (22).

2. When the power is turned on, the light will illuminate.

ADJUSTING THE PITCH CONTROL:

1. The PT-2000 is equipped with PITCH CONTROL (23) and
QUARTZ LOCK (25). When the QUARTZ LOCK is activated,

the PITCH LED (24) lights GREEN, and the speed will be
exactly 33 1/3 or 45 RPM depending on which SPEED
SELECTOR BUTTON (17) is pushed. PITCH CONTROL
automatically disengages when QUARTZ LOCK is activated.

2. When the QUARTZ LOCK is off, you can adjust the PITCH
CONTROL(23). When you move PITCH CONTROL (23) off
center, the pitch can vary +/- 10% depending on the position of
the PITCH CONTROL.

3. Push the QUARTZ LOCK (25) button to bring the speed back
to exactly 33 1/3 or 45 RPM when the PITCH CONTROL (23)
is positioned off center. Disengaging the QUARTZ LOCK (25)
will bring the platter speed back to the original pitch setting.

4. The PLATTER (2) is equipped with a STROBE RPM
INDICAT OR STRIP (26) and the POWER SWITCH (15)
contains built in STROBE LIGHTS (27). When the PLA TTER

(2) is spinning, the STROBE LIGHTS illuminate the STROBE
RPM INDICATOR STRIP (26). The bottom row of dots will

appear to be stationary when the speed of the platter is
exactly 45 RPM. The second row from the bottom will appear
to be stationary at 33 1/3 RPM.

ARM-LIFT HEIGHT ADJUSTMENT :

If the pre-adjusted distance that the CUE LEVER (18) raises the
stylus off the record surface is inadequate, it can be adjusted by
turning the ARM-LIFT HEIGHT ADJUSTMENT SCREW (28) while
simultaneously pushing down on the TONE ARM (5). Clockwise
rotation of the screw will decrease the distance and
counterclockwise rotation will increase the distance.
