I use a RayDat with Sonnet Echo SE1 TB3 as a sound card for a new Macbook Pro 16", working flawless.
Now I want to put an AEB4-O in the Sonnet chasis, but it needs power.
Usually it is powered by a computer floppy connector, providing 12v/5v power.
My question: does it actually use 12V and 5V, or maybe only one of them?
I will have to find a customized solution for that.

many thanks
Klaus
