Got a T778 in and liking it very much, it’s not without its quirks but so far it’s as good as my Naim Atom with the bonus of it being a surround reciever to.
I am not having the best of time with av presets, maybe I am just not getting what can and cannot change per input. I can’t seem to get speaker setup to not have the surrounds and centre active or have different speaker levels. I would only want two speakers active for BluOS I know it doesn’t usd then unless I tell it to upconvert to advanced stereo or surround which I am not using. But if his then is then active across all other inputs even if they are using a different speaker setup. Is it not possible to do this and speaker setup is system wide not via input. It seems to work for enabling disabling a sub mind.
Also anyway to have the two channel output lower as it’s levels compared to surround are massive and I have to reduce volume from down by nearly -20db.
I have my NAD T758 running at this moment on BluOS input with a stereo output (with a sub but I had it setup without that before.) And I have a HDMI input setup with with 4.1 surround. So I can confirm that it is possible indeed.
It has been a while since I have set it up so I can not explain it from memory (age…) I do remember that it took some time to understand the way to do it though. But only used the manual and trial and error.
Configure the T778 the way you want it to be, e.g. speakers, listening mode, etc.
Go to AV presets and select a numbered preset that is not setup, or you want to overwrite. Make sure that Yes is selected for Speakers and other sections you want saved! For example, I do not want to save speaker setup so I have it as No.
Select save current setup to preset.
Go to source setup and assign the new preset to input 6 blu os.
