Question about Denon PMA-600NE

Hello good day, my "good old" Revox A78Mk2 has unfortunately given up the ghost, well now I'm looking for one with equivalent data, i.e. the following connections are mandatory, inputs, phono, CD, tape, IR + DAB tuner, TV, outputs, 2 Lsp. Groups, headphone front, the Denon seems to have all this, only what I can't find is information on what happens when the device is switched off, i.e. switched off via a plug list, because we don't run anything on stanBy for days on end. Thank you very much for all types and hints, with kind regards Harry
