Remote power on
The amplifier can be switched on & off via a special connection from the Pro-Ject Pre Box DS via the 2,5mm
socket marked Trigger IN.
Special power-on cables (polarity

) in diverse lengths are available as accessories. The remote power-
on signal can be relayed to further units via the Trigger OUT socket.

Trigger cables may only be plugged into the sockets when the amplifier is disconnected from the
power supply and from the mains. Failure to do so may result in damage of the unit.
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
