Happy to inform that the UPS Eaton 3 S 550 works perfect with LP-16 or any other digital stuff. I plugged the power chord in/out repeatedly but the playback kept on going flawlessly. It switches over to battery fast enough.
Downside…it’s like 3kg brick. Wich doesn’t mattter really if you are going to gigs with car. But if youre flying then something else has to stay at home to avoid excess weight.
Ok, this setup has to be bomb-proof now….
