I found this diagram from the Amp+ in the archives:
https://www.hifiberry.com/docs/archive/connecting-power-supply-and-speakers-to-the-hifiberry-amp/
It shows that you can power it with a hardwired connection on the two far left pins. However, I can't find anything showing that this is an approved set up on the Amp 4 Pro, even though it has the pins. Can someone confirm that this is still an option on the Amp 4 Pro?
