Boss 2 Acrylic - power supply, Dual or Single

[johy]

So I got a new Boss 2 Acrylic. Opened it up to insert my Raspberry Pi 4. Then opened up the other side to look for the J18 jumper - but I could not find it!

 

I thus ended up using the single power supply which was supplied with the Boss 2 Acrylic. So is that enough? Or should I be using a supply for the Raspberry Pi as well.

Also, currently I am using Moode. Want to try Volumino for my Tidal connection; will it work seamlessly? Or do I need to fiddle around a bit? Thanks in advance. Moderators may please merge this with existing thread, if needed. (I did a search, but did not come across anything)
