Adjusting the azimuth

** The cartridge needle must be vertical in the record groove in order to trace
the groove wall modulations correctly.
A small screw at the bearing end of the arm allows incorrect azimuth to be
corrected if your needle is not mounted exactly perpendicular to the cartridge
body (which is often the case).
Slacken off the screw just enough to be able to revolve the arm tube without
applying force. Please note: do not remove the screw completely!
With the aid of a good magnifying glass adjust the needle until it is vertical in the groove (i.e. perpendicular
to the record's surface). Ideally this should correspond to the top surface of the cartridge body being parallel
to the record surface.
When you are satisfied that the needle is vertical retighten the screw carefully.
Under no circumstances should the arm tube be adjusted with the needle still in the record groove!
Irreparable damage may be caused to the cantilever suspension! The arm must be lifted to make
each adjustment and lowered afterwards to check it.

Anti-skating force adjustment

The anti-skating force must be adjusted according to the mass of the cartridge as
follows:
Downforce
10 - 14mN
15 - 19mN
20mN and bigger
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 those of your choice for connection to the amplifier if you wish. Your dealer can advise you on
alternative cables. 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. An earthing
wire may be connected to the screw terminal between the sockets if you encounter hum problems when using
the record player.
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 such as the PRO-JECT PHONO BOX or the PRO-JECT TUBE BOX
which is then connected between the record player and a free line level input of the amplifier.
For detailed product information please refer to the Pro-Ject web site www.project-audio.com.
The recommended load resistance for the Ortofon MC Rondo Red cartridge is: 10-200ohms/MC-input.
The recommended load resistance for the Sumiko Blue Point No. 2 cartridge is: 47kohms/MM-input.
Connection the Speed Box SE, 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 Intput ~16V socket on the Speed Box SE.
Connect the power cable supplied to the Output ~16V socket on the Speed Box SE and to the record
player's motor unit (13) before connecting the power supply to the mains.

Switching on and off

Pressing the power switch (20) alternately starts or stops the motor.
