An active subwoofer can be connected to the output sockets marked Sub.
Record output, processor loop
Out connects an analogue record device. Together with on of the inputs, it can be used as processor loop,
to operate devices like a room compensation processor.
Remote power-on, switching voltage
The socket marked Trigger provides a 12V DC switched output voltage for remote power-on of units with this
facility (such as the Pro-Ject Amp Box SE or Pro-Ject Amp Box SE Mono), which corresponds to the position
(on/off) of the power switch (A) on the front panel.
A 45cm remote power-on cable (polarity
+
) is supplied with the Pro-Ject amplifiers for connecting the
remote-switched power socket to the Pro-Ject Pre Box SE. Longer cables are available from your Pro-Ject dealer.
Do not use this trigger output for any other connections for which it is not designed.
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 Power ~16V socket before connecting the power supply to the mains.
