   b) Install the cartridge to the headshell and tighten it with screws provided with the cartridge.

6. Insert the headshell into the front end of the tonearm, and then turn the
   lock nut counterclockwise with the headshell firmly held horizontally.

7. Slide counterweight onto tonearm. Twist it lightly and it will screw onto the rear shaft of the tonearm.

8. Adjustment of horizontal “zero” balance and stylus pressure:
   (a) Remove the stylus protector from the headshell; do not touch the stylus tip during the adjustment.
   (b) Set the cueing lever to the lowered position.
   (c) Release the tonearm clamp and lift the tonearm from the armrest to free it.
   (d) Rotate the counterweight until the tonearm is approximately balanced horizontally (floats freely).
   (e) Refasten the tonearm with the tonearm clamp.
   (f) Hold the counterweight stationary with one hand and rotate only the stylus-pressure ring to bring the number “0” of the ring into alignment with the centerline on the tonearm rear shaft.
   (g) Rotate the counterweight including the stylus-pressure ring counterclockwise until the scale shows the value corresponding to the pressure of the stylus used(3g). Should you use a separate Stylus, please follow the manufacturer’s instructions.

9. Set the anti-skating control knob to the same value as the stylus pressure.

10. Install the dust cover to the main unit’s dust cover hinges.

PLACEMENT

Do not place the unit in a location where it will be exposed to direct sunlight or near a heating appliance. Do not place the unit in a location where there is high humidity or a lot of dust. The cartridge may pick up slight sound pressures or vibrations of the speakers coming along the floor or through the air resulting in feedback or “howling” sound. Find a location that is very stable and vibration-free. The legs have functions for adjusting the height of the unit itself. Adjust the legs to stabilize the main body horizontally.

CONNECTIONS

Before connecting the unit it is advised that you also consult your current equipment instruction manual.

IMPORTANT: Be sure to turn off the equipment before you make changes to the different connections.

1. Connect the power cord to an AC outlet.
2. Connect the RCA cable to the PHONO input of your AMPLIFIER.
   Output terminals| Amplifier (Receiver)
   ---|---
   L (White)| L Channel
   R (Red)| R Channel

NOTE:
• If this connection is not made or is loose, a power source “HUM” will result.
• You can also use a line input by setting the phono/line switch at the rear of the turntable to the line.

3. Connect PC via USB cord.
   

OPERATIONS

1. Turn the On/Off Switch clockwise to turn on the power, the speed indicator, and the strobe-illuminator, which is located beneath the On/Off switch, will light up.
2. Place a record on the slipmat. When playing a 45-rpm record with a large center hole, place the 45-rpm adapter on the center spindle.
3. Set the speed to match the record.
4. Remove the stylus protector from the Headshell Stylus and then release the Tonearm clamp.
5. Set the cueing lever to the up position.
6. Press the Start/Stop Button; the turntable platter will start to rotate.
7. Move the tonearm over the desired groove.
8. Set the cueing lever to the down position, the tonearm will descend slowly onto the record and begin playing.
9. When play is finished, raise the cueing lever, move the tonearm onto the Tonearm clamp.
10. Press the Start/Stop Button to stop the platter from rotating. Turn the On/Off Switch counterclockwise to turn off the power.

SUSPEND PLAY

Set the cueing lever to the “UP” position during play, the stylus tip of the cartridge will be lifted from the record.

CHANGING THE SPEED

• As long as the pitch control is in the center “detent” click position, the turntable is operated at the selected speed.
• The speed can be increased or decreased by 10% by pitch control.
• An incorrect adjustment done on purpose can also be used to have the turntable rotate extremely slow or fast.
• The strobe dots at the edge of the turntable are used for speed monitoring.

MAINTENANCE

• Clean the stylus periodically with a soft brush to prevent the accumulation of dust.
• When sound becomes distorted or noisy, check the stylus. If the stylus is worn out, replace it with a new one.
• From time to time, the dust cover and turntable cabinet should be wiped down with a soft, dry cloth.
• Volatile materials should not be used, such as alcohol, thinner, benzine, etc. They may remove the paint or damage the
  luster.

CONTROLS OVERVIEW

1. 45-rpm Adaptor
   This adapter allows you to play standard 7” EP vinyl records with large center holes. Place the adapter on the CENTER SPINDLE 7″ records.

2.   Turntable Platter
   This platter connects directly to the center spindle. The platter and center spindle hold a vinyl record perfectly center. The platter also spins the record at a consistent speed.

3. Strobe Indicators
   The PLATTER has four rows of indicators. These indicators are used to visually detail various stages of the pitch. The indicators are illuminated by the STROBE INDICATOR PILOT LAMP. Each row may appear to stand still at different pitch levels.
   Note: The use of heavy fluorescent lighting directly above the turntable will defeat the STROBE LAMP PILOT LAMP affects indicator accuracy.

4. Center Spindle
   This spindle holds the turntable PLATTER records stable and centered.

5. Strobe Indicators Pilot Lamp
   This is lamp specially designed to pulse a beam of light at the STROBE INDICATORS on the turntable PLATTER. This will give the illusion that indicators are not spinning at certain speeds.

6. Power Switch
   This is a rotary power switch. To turn the main power on turn the switch in a clockwise direction. To turn the main power off turn the switch in a counterclockwise direction.

7. Start/Stop Button
   This oversized push-button controls platter motion. When the unit is turned on the platter will not automatically begin to spin. Pressing the button once will engage the
   high torque motor and spin the platter, pressing this again will stop the platter.

8. Headshell
   The included HEADSHELL is used to connect your stylus with the tonearm.

9. Headshell Locking Nut
   After attaching the headshell to the tonearm, this locking nut will securely hold the headshell to the tonearm.

10. S-Shaped Tone Arm
    The tonearm is the mechanism that holds the HEADSHELL and stylus allowing it to glide across a record.

11. 33-RPM Speed Select Button
    Engaging this button will rotate the platter at 33 revolutions per minute (RPMs). A function LED will glow when this function is activated.

12. 45- RPM Speed Select Button
    Engaging this button will rotate the platter at 45 RPMs. A function LED will glow when this function is activated.

13. Pitch Control Slider
    This slider is used to adjust the playback pitch percentage (platter speed).

14. Tone Arm Lever
    This lever is used to safely elevate the tonearm above a record surface without endangering a record’s surface.

15. Arm Rest Clamp and Rest
    Use this rest to safely hold the tonearm in position during non-use and transportation.

16. Anti-skate Knob
    The anti-skate applies inward force to the tonearm to prevent outward skipping across the record due to the centrifugal force caused by platter rotation. The anti-skate
    the value should be equal to that of the stylus counterweight pressure.

17. Stylus-Pressure Ring
    ＊ The counterweight scale must face toward the DJ.

18. Extra Stylus Holder
    This cut-out has been designed to safely store an extra stylus headshell.

19. Counterweight
    Use the counterweight to balance the tonearm and to adjust the stylus pressure.

20. Hinge For Dust Cover

21. Phono/Line Selector
    This switch is used to change the mode of the phono output or line output.

22. RCA output jacks
    The output is able to switch to PHONO output or LINE output. For example, These jacks are used to send a low voltage “phono” level output signal to a mixer’s “phono” input jacks. Turntables should be connected to “Phono” inputs on a mixer. The red-colored RCA jack represents the right channel input and the white represents the left channel input.
