Product Description

Initial Setup

  1. Place the unit on a flat and level surface. The selected location should be stable and free from vibration.
  2. Install the turntable lid to the hinges.
  3. Remove the tie-wrap that is holding the tonearm.
  4. Put the drive belt around the Turntable Hub, and then use the provided belt hoot to help pull the belt to fit around the slot of motor pulley.
  5. Place the turntable platter through the turntable spindle.
  6. Place the slip mat on top of the turntable platter.
  7. Slide Tonearm Counterweight onto tonearm and twist it lightly onto the rear shaft of the tonearm.
  8. Adjust the counterweight to set proper stylus pressure.
  9. Locate the anti-skating weight
  10. Connect AC-DC adaptor to the Power Jack of the unit.

Note:

Do not plug the AC power adaptor to power outlet before all the assembly is completed.

Cartridge Down force Adjustment

The Counterweight supplied is suitable for cartridges weighing between 3.0-6.0g.
Gently push and turn the Counterweight onto the rear of the tonearm (with the scale facing toward the front of the turntable).
Remove the cartridge protection cap.
Lower the tonearm lift and position the cartridge in the space between tonearm rest and platter.
Carefully rotate the Counterweight until the tonearm balances out. The tonearm should return to the balanced position if it is moved up or down. This adjustment must be done carefully.

Once the tonearm is correctly balanced return it to its’ rest. Hold the Counterweight without moving it, and gently rotate the Down force Scale ring until the zero is in line with black line on the rear of the tonearm. Check whether the arm still balances out.

Rotate the counterweight counter clockwise (seen from the front) to adjust the down force according to the cartridge manufacturer’s recommendations. One mark on the scale represents 0.05g of down force.

NOTE: The recommended down force for the factory fitted cartridge is 3.0±0.5g.

Locate the anti-skating weight

You will find a anti-skating weight with small fishing line from the package, please follow below steps to locate the anti-skating weight:

  1. Slip the looped end of the fishing line over the anti-skating weight adjustment stub and into the 3rd groove (the correct anti-skating force for the factory-fitted cartridge).
  2. Pull the anti-skating weight slightly to let the tie of the fishing line move to the stub.
  3. Lift the anti-skating weight over the anti-skating weight wire support. The anti-skating weight should now be dangling in free space to the left of support.

The anti-skating force must be adjusted corresponding to the down force as follows:

Down force   Groove in the stub
5 – 10mN  1st from bearing rings
10 – 15mN    2nd ” ” ”
15 – 20mN    3rd ” ” ”
20mN and bigger      4 th” ” ”

Stereo System Connection

RCA Jacks4

  • The RCA Jacks of this unit are shared as both the Phone output jacks and the Line output jacks. They are determined by the Phono/Line Switch.
  • When used as a line output, the jacks output analog line-level signals and could be connected directly with a pair of active speakers or the appropriate input of your stereo system. When used as a Phono output, they should be connected to the phono pre-amplifier or the phono input of the stereo system.
  • The Red plug connects with the Right channel and the White plug connects with the Left channel.

Note: 

  • If the Phono/Line switch is set at LINE position but RCA jacks connected to the stereo system’s phono input, the sound might be distorted due to input overload and could damage your stereo system.
  • If the Phono/Line switch is set at PHONO position but RCA jacks connected to the stereo system’s line input, the volume will be very low due to lacking signal pre-amplification.

RCA Jack is not designed to be connected directly to the passive/unpowered speakers and if it does, the volume will be very low.

Speaker Connection
The spring clip speaker terminals deliver amplified, speaker-level signals as output and should be connected with the passive speakers.

  4. Mount the new cartridge to the headshell and tighten it lightly. Do not completely tighten the screws at this moment.
  5. Connect the wire leads to the new cartridge’s terminals. The wire lead color are as below:
    White Left channel positive (L+)
    Black Left channel negative (L-)
    Red Right channel positive (R+)
    Black Right channel negative (R-)
  6. Adjust the cartridge’s position to make sure it is precisely aligned on the headshell so that the stylus will be tracking the grooves in parallel perfectly.
    To achieve this, place the included paper cartridge alignment protractor over the turntable spindle, carefully lift the tone arm and place the tip of the stylus on the points marked 130mm and 250mm respectively. Fine tune the cartridge’s position on the headshell until the cartridge is perfectly in parallel with the reference lines at both posits.
  7. Tighten the screws completely once the perfect alignment is achieved.
