This turntable is supplied with a factory-fitted and adjusted cartridge.**The following instructions for adjusting the cartridge are provided in case the cartridge is replaced by a different model at a later date.

Installing the Lid

Install the Lid carefully over the hinge prongs.

Turntable Platter and Belt Setup

  1. Install the drive belt over the inner ring under the platter and make sure it won’t fall off during the setup.
  2. Place the platter through the turntable spindle, then rotate the platter until you see the drive motor pulley through the window at the top left corner.
  3. Carefully grab the drive belt and put it around the slot of the motor pulley.
  4. Connect the power adapter to the turntable and power on the turntable.
  5. Set the Motor Start/Stop switch to the Start position to see if the platter motor spins. If the platter does not spin, try the steps listed above again.

Cartridge Downforce 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 Downforce Scale ring until the zero is in line with a black line on the rear of the tonearm.Check whether the arm still balances out.

– Rotate the counterweight counterclockwise (seen from the front) to adjust the downforce according to the cartridge manufacturer’s recommendations. One mark on the scale represents 0.05g of downforce.

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

Locate the anti-skating weightYou will find an anti-skating weight with a small fishing line from the package, please follow the 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 Groove 3 (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.

Slip the loop of the anti-skating weight’s thread over the 3nd groove of the stub to set the correct anti-skating force for the factory-fitted cartridge. Feed the thread through the loop of the wire support.

Anti-skating force adjustment

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

Down force5 – 10mN10 – 15mN15 – 20mN20mN and bigger Groove in the stub1 st from bearing rings2 nd ” ” ”3 rd ” ” ”4 th ” ” “

Slip the loop of the anti-skating weight’s thread over the 3rd groove of the stub to set the correct anti-skating force for the factory-fitted cartridge. Feed the thread through the loop of the wire support.

Stereo System connection

RCA Jacks

  • 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.

Main Power Connection

The power adaptor is in the foam packing material. Unpack the power adaptor and plug the small end into the DC power jack located at the backside of the turntable. Plug the power adaptor into your power outlet.

Maintenance and Cleaning

Your turntable requires little or no regular maintenance. Remove dust with a slightly damp antistatic cloth. Never use a dry cloth, this will create static electricity and attract more dust! Antistatic cleaning agents are available at specialist stores but must be applied sparingly to avoid damage to rubber parts. It is recommended to install the needle cover before cleaning or maintenance is carried out to avoid damage.If the turntable is not used over a long period of time, the drive belt should be removed to prevent unequal stretching.

NOTE: Always disconnect the record player from the power supply as a precaution before maintenance!

Useful TipsThe turntable should be positioned on a low-resonance surface such as wood or multiple layer plyboard to avoid structural vibrations disturbing playback.

Cartridge Replacement

  1. Before replacement, put the stylus protector back on the stylus to prevent damage to the stylus during the replacement process.
  2. Carefully remove the wire leads from the original cartridge.
  3. Loosen the two screws on the headshell that are securing the cartridge and then remove the original cartridge.
  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 codes 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 tonearm 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 points.
  7. Tighten the screws completely once the perfect alignment is achieved.

NOTE: If you are unfamiliar or uncomfortable with completing this procedure, we recommend consulting with a professional to perform the installation.

Potential Incorrect Use and Fault ConditionsThese turntables are manufactured to the highest standards and undergo strict quality controls before leaving the factory. Faults that may possibly occur are not necessarily due to material or production faults but can sometimes be caused by incorrect use or unfortunate circumstances.Therefore the following list of common fault symptoms is included.

The platter doesn’t turn although the unit is switched on:– The unit is not connected to the main power supply.– No power at the outlet.– Drive belt is not installed or has slipped off.– The unit automatically switched in standby mode, power OFF and ON again on the backside.

No signal through one or other channel or both channels:– Phone input not selected at the amplifier.– Amplifier is not switched on.– Amplifier or speakers muted.– No connection to the speakers.– No connection between turntable and amplifier.– Wire leads are not connected to the cartridge.

Strong hum on phono input:– No ground connection from the cartridge, arm, or arm cable to amplifier or ground loop.– Turntable too close to speakers.

Distorted of inconsistent sound from one or both channels:– Turntable is connected to wrong input of the amplifier.– Needle or cantilever damaged.– Drive belt overstretched or dirty.– Platter bearing without oil, dirty or damaged.– Dust on the stylus.– MM/MC switch on pre-amplifier set incorrectly.

Remark: Due to the ERP Stage 2 requirements for power-saving measures, a unit that is connected to the mains power will switch itself to standby mode automatically if no music has been playing for about 20 minutes.If your unit switches off regularly, this is no defect.
