Mains power connection and methods to switch the unit on and off
Connect the low voltage plug from the power supply to the 2x48V= socket of the amplifier before
connecting the power supply to the mains. Amp Box DS2 Mono can be switched on and off by using 2
different methods which are equal in priorities.
1.
Using front pushbutton to switch on or into 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.
Please note: If a trigger signal is present Amp Box DS2 Mono can’t be switched off by the
pushbutton.
2.
Remote power on - triggers
Amp Box DS2 Mono can be switched on via other Box Design components when a 12V trigger voltage is
present at the 2.5mm socket marked Trigger Input. 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 Output socket. When the 12V trigger signal is switched off, Amp Box DS2 Mono will also switch off.
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.
