Gemini SA-2400 manual Operating Instructions

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.

ADJUSTING TONE ARM HEIGHT:

The tone arm height is adjustable between 0 and 6 mm. A HEIGHT SCALE (14) (in 0.5 mm increments) is provided to aid in an accurate setting.

1.Unlock the tone arm by turning the ARM LOCK (15) 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 ARM HEIGHT ADJUSTMENT RING (13) until the reference line on the ring is positioned at the correct scale reading.

4.Lock the tone arm by turning the ARM LOCK (15) knob clockwise until it reaches the lock position.

	TABLE A
CARTRIDGE HEIGHT		SCALE READING
(mm)
15		0
16		1
17		2
18		3
19		4
20		5
21		6

For example, if the height of the cartridge is 18.5 mm, the ARM HEIGHT ADJUSTMENT RING (13) reference line should be positioned between 3 and 4 on the HEIGHT SCALE (14).

INSTALLING THE DUSTCOVER:

1.Mount the hinges onto the dustcover.

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

3.Always raise the dustcover before removal.

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

CONNECTIONS:

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

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

Operating Instructions

BASIC OPERATION:

1.Place a record on the NEOPRENE MAT (4) which sits on the PLATTER (2).

2.Select the desired speed by depressing the 33 or 45 SPEED SELECTOR (18) button. Press both the 33 and 45 SPEED SELECTOR buttons at the same time for 78 RPM.

3.Turn the POWER (16) switch to the “ON” position, at which point the strobe illuminator (built into the POWER switch 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 (9) found on the ARM REST (10).

6.Push the START STOP (17) button. The turntable PLATTER (2) will start to spin.

7.Push the CUE LEVER (19) 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 (6) will slowly lower onto the record at which time play will begin.

9.When play is over, raise the TONE ARM (6), move it to the ARM REST (10), and secure it with the ARM CLAMP (9).

10.You now have the option of turning off the power by turning the POWER (16) switch to the “OFF” position, or stopping the PLATTER (2) by pushing the START STOP (17) button and engaging the electronic brake.

INTERRUPTING PLAY:

1.Pushing the CUE LEVER (19) to the “UP” position will cause the TONE ARM (6) to lift, stopping play.

2.Pushing the CUE LEVER (19) to the “DOWN” position will cause the TONE ARM (6) to slowly lower onto the record at the point where play was interrupted.

PLAYING 45 RPM RECORDS:

1.When playing a 45 RPM record with a large center hole, first place the 45 ADAPTER on the center spindle.

2.Be sure that the 45 SPEED SELECTOR (18) button is pushed and the 45 speed indicator is illuminated.

TARGET LIGHT:

1.Push the TARGET LIGHT SWITCH (21) firmly and the TARGET LIGHT

(22)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.

ADJUSTING THE PITCH CONTROL:

1.The SA-2400 is equipped with PITCH CONTROL (24) and QUARTZ LOCK (26). When the QUARTZ LOCK is activated, the QUARTZ LOCK LED (25) lights GREEN, and the speed will be exactly 33 1/3, 45 or 78 RPM depending on which speed has been selected regardless of the position of the pitch control. PITCH CONTROL automatically disengages when QUARTZ LOCK is activated.

2.When the QUARTZ LOCK is off, you can adjust the PITCH CONTROL (24). When you move PITCH CONTROL (24) off center, the pitch can vary +/- 10% depending on the position of the PITCH CONTROL.

3.Push the QUARTZ LOCK (26) button to bring the speed back to exactly 33 1/3, 45 or 78 RPM when the PITCH CONTROL (24) is positioned off center. Disengaging the QUARTZ LOCK will bring the platter speed back to the original pitch setting.

4.The PLATTER (2) is equipped with a STROBE RPM INDICATOR STRIP (27) and the POWER (16) switch contains built in STROBE LIGHTS (28). When the PLATTER is spinning, the STROBE LIGHTS illuminate the STROBE RPM INDICATOR STRIP. The bottom row of dots will appear to be stationary when the pitch is -3.3%. The second row of dots from the bottom will appear to be stationary when the speed is exactly 33 1/3, 45 or 78 RPM depending on which SPEED SELECTOR (18) buttons are pushed. The third row of dots from the bottom will appear to be stationary when the pitch is +3.3%. The top row of dots will appear to be stationary when the pitch is +7.2%.
