Safety instructions for using the power supply

  • The unit should only be connected to a mains voltage supply of 100- 240 V~, 50/60 Hz.
  • Never try to operate the unit with a different voltage.
  • Only use the supplied power supply or an original Dual alternative.
  • The mains plug should only be connected after installation has been completed according to the instructions.
  • Use a suitable, easily accessible mains connection and avoid using multiple sockets!
  • This socket should be as close to the unit as possible.
  • Make sure the power cable or plug is always easily accessible so that the unit can be disconnected quickly from the power supply!
  • Lay the mains cable in such a way that no one can trip over it and do not place any heavy objects on the mains cable.
  • Fully insert the mains plug into the socket.
  • Do not touch the mains plug with wet hands—risk of electric shock!
  • If the mains plug of the unit is defective or if the unit shows other damage, it must not be operated.
  • When unplugging the mains cable from the socket pull on the mains plug, not on the cable.
  • Disconnect the mains plug from the socket if you do not intend to use the unit for a prolonged period. Only pull on the plug itself.
  • In the event of malfunctions or smoke and odour coming from the housing disconnect the mains plug from the socket immediately!
  • Before a thunderstorm sets in, disconnect the mains plug from the socket.

Set Up

Platter and belt installation

The record player is delivered with the drive belt already fitted around the turntable flange. The belt is provided with a red tape so that it can be pulled over the drive motor pulley. (pic. 1)

  1. Place the turntable on the turntable spindle. Rotate the turntable until the cut-out is positioned over the motor pulley (at about the 8 o’clock position).
  2. Using the red tape, pull the drive belt over the motor drive pulley and position it in the centre of the pulley. Then remove the red tape.
  3. Now place the turntable mat on the turntable.


The tonearm is secured at the tonearm rest with a coated wire and the safety clip. Remove and discard the coated wire and open the safety clip to play the record.

Fitting the headshell

Fit the removable headshell onto the tonearm as described below: (pic. 2)

  1. Place the headshell (1) into the socket (2) at the end of the tonearm (3).
  2. Hold the headshell, while turning the socket (2) in the direction of the arrow.

Counterweight fitting

Fit the supplied counterweight (2) onto the tonearm (1) by screwing it on from behind. Keep the dial facing forward. The counterweight is used to set the correct tracking force for the pick-up. (pic. 3)

Balancing the tonearm

Damage to the stylus
Ensure that the stylus does not come in contact with the platter mat, or any other part of the turntable.

  1. Place the turntable on an even horizontal surface.
  2. Remove the stylus guard (page 20).
  3. Lower the tonearm lift via the tonearm lift lever.
  4. Position the tonearm in between the platter and the tonearm rest. (not resting on the stylus)
  5. Turn the anti-skating dial (3) to „0” (pic. 3).
  6. Turn the counterweight (2) backwards or forwards until the tonearm reaches a horizontal balance.
  7. Place the balanced tonearm back onto the tonearm rest and secure it with the clip.
  8. (Pic 4) Hold the counterweight (1) in position while turning the tracking force dial (2) to „0“ (12 o’clock position).

Tracking force

The tracking force needs to be adjusted according to the installed pick-up. (pic. 4)

  1. Adjust the entire counterweight (1) including the scale to the required weight (2).
  2. The tracking force weight can be read from the scale.
    Note: The recommended force / weight for the supplied pick up is between 1,6 g and 2,0 g. If in doubt, please consult the pick-up manufacturer for recommended values.


The skating force pulls the tonearm towards the centre of the platter. This increases the pressure on the inside wall of the groove. The ANTI-Skating force compensates
this movement and ensures the ideal tracking of the stereo information on the vinyl.

  • Set the Anti-skating dial (1) to the same value setting as the tracking force. (pic. 5)

Dust cover fitting

  1. Slot both hinges (2) into the housings (3) in the back of the turntable.
  2. Uniformly push the right and left dust cover (1) receptacles onto the hinges

Connection to Amplifier

The turntable comes with a built-in phono pre-amplifier. It can be either connected to the phono input or the line input at the amplifier. The built-in phono stage can switched on or off via a switch in the back of the turntable.


  1. Connect the RCA cable to the Audio output „AUDIO OUT” (2) at the turntable and the PHONO input sockets at the amplifier.
  2. Move the switch (1) into the position: PHONO.
  3. Connect the ground connection GND (3) with the amplifier to avoid noise.
    Ensure the correct connection of the cable. (red = right channel, white = left channel)


  1. Connect the RCA cable to the Audio output „AUDIO OUT” (2) at the turntable and the LINE / AUX input sockets at the amplifier.
  2. Move the switch (1) into the position: LINE.
  3. Connect the ground connection GND (3) with the amplifier to avoid noise. Note: Ensure the correct connection of the cable. (red = right channel, white = left channel)

Connection to Power Supply

Different adapter plugs (1) are included with the product. Find the specific adapter relevant to your country and socket system. Fit it to the power supply (2).

  1. Fit the socket adapter into the power supply and twist in the direction of the arrow (A).
  2. Check that the adapter is locked correctly (B).
  3. Plug the power supply into a power socket (C). Note: Only use a factory supplied or approved power supply.

Damage to the turntable!
Incorrect voltages can damage the product. Ensure that the mains voltage is within the stated specification.

Operating the turntable

Removing / Attaching the stylus protection cap

Remove the stylus protection cap from the pick-up (1) prior to playing a record. (Pic.1)

  1. Push the stylus cap (2) on the bottom (B) as seen in the diagram. Hold in position (A) while move it up in circular motion (C).
  2. Replace the cap after playing the record.

  5. Carefully move the tonearm away from the tonearm rest and position it above the first groove on the record. The motor is turned on.
  6. Lower the tonearm with the lift lever.
  7. The tonearm will return to the tonearm rest automatically at the end of the record and the motor will switch off.
  8. Secure the tonearm with the safety fastener on the tonearm rest.

Note: The tonearm can be raised at any point, even for short periods. The platter will continue to turn.

To play the record (automatically) Pic.2

  4. Release the safety fastener on the tonearm rest and press the start button (1).

  5. The platter will start turning and the arm will move towards the first groove and will be lowered onto the record. The LED will flash during the operation.

  6. The operation can be stopped at any time with the STOP button (2). The tonearm will return to the tonearm rest automatically.
    The LED will flash.

  7. The tone arm will return to the tonearm rest automatically at the end of the record and the motor will switch off.

  8. Secure the tonearm with the safety fastener on the tonearm rest.

To set the speed

The exact speed is fixed through an internal processor. There is no further adjustment.

Replacing the stylus

The stylus is naturally exposed to wear and tear by the playback process. Therefore, we recommend regular inspections.

  1. Remove the stylus by pulling diagonally downwards. (Pic. 3)
  2. Insert the stylus by doing the performing the reverse action.

Worn or damaged (splintered) styluses ruin records.
When you need to replace a stylus, use the original type if possible.\

Cleaning & Troubleshooting

Cleaning stylus and record

Clean the stylus and record prior to every record played. That minimises premature wear and tear.

Damage to components!

  1. Carefully wipe the stylus brush in a front to back motion under the stylus.
  2. To clean a record, use a carbon fibre brush to wipe gently and diagonally over the record.

Note: Brushes and accessories are available in the Dual shop: www.dual.eu
