How to make Plinius SB-301 go into standby.

There are two small terminal screws on the back of the amp called "Remote Trigger Terminals" It says by connecting a processor with a remote trigger signal to these terminals. Does anyone know ways I can do this. I don't get what is needed.
Some pre-amps or system controllers can activate with a 12v "trigger" signal; If your pre-amp processor has a 12 v trigger out, you connect it there and then turning the processor on will turn on the amp.
When the amp is not in use it goes into stand-by mode.
