Dear music lover,
thank you for purchasing a PRO-JECT AUDIO phono amplifier.
In order to achieve maximum performance and reliability you should study these instructions for use carefully.
Warning of a hazard for the user, the unit or possible misuse.
Important notice.
Setting the cartridge mode
The phono amplifier must be used in either MM (moving magnet) or MC (moving coil) mode according to the
construction principle of the pickup cartridge to be used. Since most cartridges use the MM (moving magnet)
principle the phono amplifier is factory set to operate in this mode. To find out which type your cartridge is
please consult the literature accompanying your cartridge. The literature for MC cartridges should also specify
the correct impedance and capacity into which the cartridge is designed to work. If in doubt please consult
your dealer.
A switch at the back of the phono amplifier sets the correct level of amplification for the cartridge.
Before setting MM / MC mode the unit must be disconnected from the power supply and amplifier.
Connecting the record player or a line level source
Connect the tonearm signal lead to the sockets Phono-In of the phono amplifier. The earthing wire of the
tonearm signal lead may be connected to the screw terminal if you encounter hum problems when using the
record player. The signal lead of a line level source has to be connected to the socket Line-In.
Take care to connect the left and right channels correctly. The right channel is usually marked red, the left
channel black or white.

Connection to the amplifier
Connect the Out of the phono amplifier to a line input (such as AUX, CD, Tuner, Tape or Video) on your

Make all connections whilst the phono amplifier is disconnected from the power supply.

on the amplifier.
Mains power connection
The phono amplifier 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 Power ~16V socket of the phono amplifier before connecting the power supply
to the mains.
