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

Take care to connect the left and right channels correctly. The right channel is usually marked red, the

left channel black or white.

The red speaker terminals carry the positive signal (+), the black speaker terminals the negative

signal (–). Make sure the polarity of the connection is correct at each end of the cables.

Only connect one loudspeaker with an impedance not less than 2 ohms per channel.

Never use any other power supply than the one supplied with the unit.

Connection to the preamplifier

The RCA/cinch sockets marked Left /Right are for connecting the cables from your pre-amp or AV processor.

Connection to the speakers

The output terminals accept loudspeaker cables terminated with 4mm Banana plugs, spades connectors

or naked wire.

Mains power connection

The unit 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 2x48V= socket of the amplifier before connecting the power supply to the mains.

Remote power on

The amplifier can be switched on & off via a special connection from the Pro-Ject Pre Box SE via the 2,5mm

socket marked Trigger IN.

A 45cm long power-on cable (polarity

) is supplied for this purpose. Longer cables are available as

accessories. The remote power-on signal can be relayed to further units via the Trigger OUT socket.

To switch on from standby or to standby

The pushbutton on the front panel of the unit alternately turns the power on or returns it to standby mode. The

blue LED on the front panel shows that the unit is powered on.
