Precauons
SAFETY PRECAUTIONS:
Power sources:
This product should be operated only from the type of power source indicated on the rear panel rang
label. If you are not sure of the type of power supply to your home, consult your product dealer or local
Power Company.
Venlaon holes:
If objects are placed on top of this unit, the heat generated inside may not be able to dissipate properly.
This will cause the internal temperature to rise and will adversely aect the performance of the product.
Remember that a great deal of heat can be generated when this product is used for long periods of me.
Installaon Locaon:
Do not install the unit in any of the following locaons as this may result in a deterioraon in perfor-
mance or malfuncon:
• Locaons exposed to direct sunlight or near objects radiang heat such as heang appliances.
• Locaons exposed to moisture or humidity.
• The stylus cartridge is very sensive and may pick up slight sound pressure or vibraons from your
loudspeakers which can travel along the oor or through the air resulng in feedback or howling
sound. Find a locaon which is very stable and vibraon free to reduce interference.
• The feet on the base of the unit funcon for both dampening and height adjustment. Adjust the feet
to stabilize the main body securely and horizontally level.
Operang Temperature:
This unit may not perform at its best in an extremely hot or cold environment. The opmum
ambient temperature range of operaon is between 5°C ~ 35°C.
GENERAL PRECAUTIONS:
• Always clean the stylus both before and aer playing a record with a so brush designed specically
for cleaning stylus. Also remember to clean the record with a suitable brush on both sides before
and aer each use.
• Be careful not to make the turntable vibrate while a record is playing as this can result in damage to
the stylus and the record.
• When changing over the headshell, clamp the tone arm to the arm rest so that the tone arm sha is
not strained in any way.
• Place only one record at a me on the plaer. If two or more records are stacked on the plaer, the
stylus will not make proper contact with the grooves, and this will impair the quality of audio repro-
ducon and cause damage to both the stylus and the record.
• Volale liquids must not be used to clean any part of this unit, such as solvents, alcohol, paint thin-
ners, etc. The use of such liquids may remove or damage the painted nish. Please avoid.

Connecons
TURNTABLE CONNECTIONS:
Before connecng the unit it is advised that you also consult your current equipments instrucon manu-
als to ensure product compability and to ensure proper use.
IMPORTANT: Be sure to turn o the equipment before you make changes to any connecons.
1. Phono / Line Switch:
This unit has the ability to output either a PHONO signal or a LINE signal via the RCA output on the rear
panel of the unit. The voltage and Impedance levels of the PHONO output and LINE output are very dif-
ferent. It is therefore extremely important to set this switch correctly.
If you connect this unit to a PHONO INPUT on your Receiver, Amplier or Mixer etc: Set the PHONO/
LINE Switch to ‘PHONO’.
If you are connecng this unit to a LINE INPUT on your Receiver, Amplier, Mixer, etc: Set the PHONO/
LINE Switch to ‘LINE’.

*Important Notes on Phono vs. Line Inputs & Outputs:
It is not suitable to use the PHONO output of this turntable with a LINE Input on your Amplier or
Receiver. If you do connect this unit to a LINE INPUT when the switch is set to the PHONO posion, the
resulng playback will be very low and almost inaudible.
It is even more important that you do not use the LINE output of this turntable with a PHONO Input on
ANY Amplier, Receiver, etc. If you do connect this unit to a Phono input when the switch is set to the
LINE posion, the resulng playback will be extremely loud and distorted and may easily cause serious
damage to your equipment, including your loudspeakers.
3. USB Cable Connecon:
Connect the USB output on the Turntable to any available USB input on your PC or Mac Computer. This
will enable you to record from your vinyl to an MP3 digital audio le using the free Audacity soware.
4. Power Cable Connecon:
Plug the mains power cable into your homes 240V mains power outlet and switch ON.
Adjusng the Tonearm & Stylus
TONEARM BALANCE ADJUSTMENT:
1. Set the ANTI-SKATE dial to ‘0’ posion.
2. Remove the Stylus cover.
3. Release the arm rest clamp and set the cueing lever to the up posion to li the tone arm up and o
the arm rest.
4. Move the tonearm over to the space between the arm rest and the plaer, taking care not to dam-
age the stylus.
5. Set the cueing lever to the down posion.
6. Support the headshell’s nger-li with one nger and aain level balance by turning the counter-
weight either clockwise or counter-clockwise. ‘Level balance’ means when the tonearm is parallel
to the plaer, and the tonearm therefore sits sll half way between the full up posion and the full
down posion of the tonearm movement range. The tonearm should not lt either toward the coun-
terweight side or the headshell side. Once the tonearm is hovering perfectly horizontal, the stylus
tracking weight is now set at zero.
7. Return the tonearm to the arm rest and fasten the arm rest clamp.
8. As the tracking force is zero when the tone arm is balanced level, turn only the tracking-force scale
ring in front of the counter-weight, and set the ‘0’ posion on the scale to the index line on the top
of the counterweight sha. Be sure to hold the counterweight with the other hand so that it does
not turn together with the scale ring.
9. Now turning the counterweight and scale ring together, set the correct tracking force opposite the
index line on the counterweight sha. The tracking-force scale ring has 0.1 gram steps and one full
turn of the counterweight will yield a tracking force of 4.0 grams.
