Curt...

I've got two of these now.. One with no audio but video and setup controls (not even test tones) and one with no video / setup but puts out audio. :-( I hear what you're saying abut HDMI being on a different board, but when I open up mine (both of them), HDMI 1 is plugged into the same slot on the mother board as all the HDMI inputs. Maybe there is some other rerouted circuitry going on but as far as where it is plugged in, all the HDMI seem to be on the same card and in the same slot. More than glad to take a picture and upload. I'm certainly not questioning you because I know you were involved with the design to some extent, but it sure looks like they're all plugged into the same slot...

I'd dearly love to figure out how to make one good one out of the two.

Just another question... (and all things finally reach a point of technology passing them by). We know the 972 can't do 3D. Question is with its 1.4a HDMI connections will it route HDR / 4K, etc. Are we looking to be at a point where some switching can still be done with the R-972, but where some devices are going to need a direct connection to the set with audio only (TOSLINK/DIGITAL)? The 972 did not support ARC either if memory is serving me correctly..

Question of bandwidth- HDMI 2.0 has more data and higher bandwidth specs then 1.4a. Even if the R972 isn't processing, in any case, it won't pass a signal that requires higher bandwidth then spec, which is a function of pixels, color depth, refresh rate, etc.

Re HDMI boards, you'll need to get a copy of the service manual for locations. I learned about the two HDMI boards from the Sherwood tech who provided warranty repair work while it was available.

First thanks!

So I take it you're saying the 4k, HDR, etc. are going to more than likely be in the same category as 3D as far as support? Not a question of intent, just what the design was capable of doing at the time?

RE: Service manuals.. Anyone have a clue where I could even see one? Is there a PDF file someone might be able to share? Sure would help me with the two I have..

I think I know the answer to this but wanted to double check. Other than being routed through the receiver's volume control, is the R-972's 7.1 channel analog input essentially a pass-through connection with no other processing or "molesting" done to the signal? I know that Trinnov processing is not available on that particular input, but was wondering if the unit does anything else to the signal that would have a negative effect on it? I'd like to be able to use the multi-channel analog input to directly connect a source with better quality DAC's for music listening, but if the R-972's circuitry on that input is then going to turn around and degrade or dirty up the signal somehow, it's kind of pointless. Thanks.

It remains in the analog domain unless you change it.

I just got a 4K TV and want to send the video from my Nvidia shield directly to the TV so it can play 4K but of course I want to use the 972 for audio. If I put a splitter on the output of the shield and run one to the 972 will the receiver just ignore the video and just play the audio portion or reject everything?

Don't think you need to do that. I don't have a shield, but looks like from the diagrams I saw, you can go HDMI into the TV and then optical out of your set into the 972. I didn't see any other audio outs on the Shield other than USB which would be stereo. You could also do something like a Sherwood Newcastle HSB600 splitter (which will give you HDMI in and digital Audio out). I have two (selling one) and used all the time with my 972s when they worked. I have two still, one with audio out and one with video out (you'd figure I could join them!). Moved to a Denon 4311CI.. Miss the Trinnov but Audyssey XT32 is bad either. Hope this helps.. let me know if interested in HSB 600.. Like new in box..

Thanks, I looked at splitters that had optical out but I am wanting to play HD audio which you can't do over optical plus the splitter would need to support 4K with HDR.
