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 or Pro-Ject Amp Box Mono), which corresponds to the position (on/off) of the power switch on the front panel.
Input Select button lights up green. If Input 2 is selected, it lights up red. If the optional input expander Pro-Ject Switch Box is connected, Input Select will also select the additional inputs provided by the Switch Box. For further details please see the user guide of the Pro-Ject Switch Box. Volume Adjust the volume to the desired level using the large knob marked Volume on the front panel.
