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.

Use the supplied jumpers to set the impedance and the recommended load resistance.
The following settings are available:
