Topic: Fireface UCX/ARC USB Questions

Hello,
I just bought a Fireface UC and an ARC USB, and realised that some fonctions are "missing".
I would like to control preamp gains with the ARC USB, and also, save the total mix state into the interface. It seems this is impossible with the UC, but possible with the UCX.

It is unclear in the ARC's manual that the gains control are missing with the UC. Can someone confirm those 2 fonctions are available with the UCX ?

I didn't saw this information in the ARC Manual, is it possible to enable 48V power with the remote ?

Thanks a lot,
Simon
