The socket marked Trigger Amp provides a 12V DC switched output voltage for remote power-on of units with this facility (such as the Pro-Ject Amp Box S or Pro-Ject Amp Box S Mono), which corresponds to the position (on/off) of the power switch on the front panel.
If the optional input expander Pro-Ject Switch Box S is connected, the input selector will also select the additional inputs provided by the Switch Box S. For further details please see the user guide of the Pro-Ject Switch Box S.
