How it works

Three steps.
Zero effort.

01
Connect the trigger

Plug a standard 3.5mm mono jack cable from your amplifier's 12V trigger output into the Trigger Box or Hub input.

02
Wire your device

Connect your IEC mains cable through the Trigger Box — power in and power out. No soldering, no internal modification required.

03
Everything in sync

When your amplifier powers on and sends the 12V signal, the Trigger Box closes the relay — your connected device powers up automatically.
