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.
- MM
- MC
The following settings are available:
MC -
∗ 17ohm s /120pF (jumper on 22, 100 and 220 Ohms)
MC - ∗ 18ohm s /120pF (jumper on 22 and 100 Ohms)
MC - ∗ 20ohm s /120pF (jumper on 22 and 220 Ohms)
MC - ∗ 22ohm s /120pF (jumper on 22 Ohms)
MC - ∗ 69ohm s /120pF (jumper on 100 and 220 Ohms)
MC - ∗ 100ohm s /120pF (jumper on 100 Ohms)
MC - ∗ 220ohm s /120pF (jumper on 220 Ohms)
MM - 47kOhm s /120pF (no jumper)
MM -
∗ 47kOhm s /220pF (jumper on 100pF)
MM - ∗ 47kOhm s /340pF (jumper on 220pF)
MM - ∗ 47kOhm s /440pF (jumper on 100pF and 220pF)

Before setting MM / MC mode ore resetting jumpers the unit must be disconnected from the power
supply and amplifier! Please set both channels equally.
Subsonic filter
A switch at the back of the phono amplifier activates and deactivates the subsonic filter.

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.
