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 Box 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. To find out which type your cartridge is please
consult the literature accompanying your cartridge. If in doubt please consult your dealer.
A switch at the back of the Phono Box 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
Connect the tonearm signal lead to the In of the Phono Box.
Take care to connect the left and right channels correctly. The right channel is usually marked red, the left
channel black or white. The earthing wire of the tonearm lead should be connected to the earth terminal.
Connection to the amplifier
Connect the Out of the Phono Box to a line input (such as AUX, CD, Tuner, Tape or Video) on your amplifier.
Take care to connect the left and right channels correctly. The right channel is usually marked red, the left
channel black or white.
!
Make all connections whilst the Phono Box is disconnected from the power supply.
Do not connect the Phono Box output to a phono input (sometimes labelled gram, disc or RIAA) 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 Box before connecting the power supply to
the mains.
