INSTRUCTIONS FOR USE
Pro-Ject Phono Box II USB
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
Connect the tonearm signal lead to the In of the phono amplifier.
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 amplifier 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 amplifier is disconnected from the power supply.
Do not connect the phono amplifiers output to a phono input (sometimes labelled gram, disc or RIAA) on the amplifier.
