Hang the loop of the thread of the anti-skating weight in the groove of the anti-skating stub (15) corresponding
to the downforce applied to your cartridge and feed the thread through the loop of the wire support (17).
Connection to the amplifier
The record player has gold plated female RCA phono sockets (14) so you can substitute the interconnect cables
supplied with higher quality cables such as the Pro-Ject Connect it interconnect cables for connection to the
amplifier if you wish.
Use the Phono input (sometimes labelled gram, disc or RIAA) on your amplifier. Make sure that the phono
input offers correct matching and amplification for the type of cartridge used. Line inputs (such as CD, Tuner,
Tape or Video) are not suitable.
Take care to connect the left and right channels correctly. The right channel is usually marked red, the left
channel black or white. Check the manual supplied with your amplifier for relevant information. The earthing
wire of the tonearm lead should be connected to the earth terminal on your amplifier (if provided).
If your amplifier does not have an input suitable for phono cartridges you will require a separate phono
amplifier stage for MM or MC cartridges which is then connected between the record player and a free line
level input of the amplifier.

The recommended load impedance for the factory fitted cartridge is: 47kohms/MM-input
Mains power connection
The turntable is supplied with a power supply suitable for your country's mains supply. Check the label before
connecting to ensure compliance with the mains rating in your house.
Connect the low voltage plug from the power supply to the socket (13) on the rear of the record player before
connecting the power supply to the mains.
Fitting the lid
Fit the lid (dust cover 10) carefully over the hinge prongs and adjust the screws (12) until the lid stays open
where you want it to without being too stiff to open or close.
Switching on and off
Pressing the power switch (20) alternately starts or stops the motor.
Changing replay speed
To play records at 45 r.p.m. first remove the platter (5). Using the accessory tool provided (3a), hook the belt
(3) over the larger diameter part of the motor pulley (2). Refit the platter. To revert to 33 r.p.m. repeat the
proceedings using the smaller step on the pulley.
When the Pro-Ject Speed Box is used speed change between 33 and 45 r.p.m. is electronic. There is
no need to move the belt manually.
*** In addition, 78 r.p.m. is available after fitting a special pulley, which may be purchased as an
optional extra.
