Remember, perceived volume doubles every 10dB. So if it is at well nigh zero at -80dB then -70dB will be twice as loud as well nigh zero, which would be very very quiet, -60dB very quiet, -50dB quiet... If -30dB is normal -20 would be loud and -10 intolerable.

Kinda like compound interest!

You said you set the Denon at -30 to -25. That's less than 1 Watt per channel with that amp and the 80s.

Red/white RCA cables are just analog left and right stereo. I imagine your on-board sound chip would be downmixing the 5.1 to 2.0 to output through those cables. The Rx could then be set to 'DPLII movie' or NEO 6 or whatever to upmix back into a 5.1, but I don't think it would be quite as good as a straight digital signal (toslink/co-ax).

Thanks again!

Just got back from the store. Picked up an DVI -> HDMI for the media PC to the receiver and then picked up a PS3 for blu-ray. It occurs to me I'm putting all of this stuff into the front end, and I don't even have the 1080p projector yet, just a 720p/1080i projector.

So here is my question. My projector has VGA, DVI, RCA, S-Video, and R232 inputs. My media PC has DVI outputs. I want to get the highest possible quality video on the projector (720p or 1080i). To do this which video cables and inputs should I use? I was thinking of going DVI -> HDMI into the denon and then HDMI -> DVI into the projector (man I wish my projector had HDMI). You may be asking yourself 'Greg, why not just run DVI straight from the media PC to the projector?' which is a valid question, except that I want it to run through the receiver so I can switch it without having to use another remote.

Any input would be greatly appreciated. Also, if I am asking too many questions let me know...I don't know what 'abuse' of the forum is defined as, but I am capable of asking tons of questions (philosophy major).

Thanks!

Greg

you don't need HDMI going to the projector as projectors don't have speakers. DVD and HDMI pass the same digital video so just run your HDMI/DVI cable to the projector, that way you get 720p or 1080i video passed to the projector.

I use HDMI/DVI from my HTPC to my Z2 720projector and HD looks awesome over the air.

Are you saying you run HDMI out of your PC to HDMI in your projector?

If I run DVI -> HDMI from the HTPC to the receiver, then run HDMI -> DVI from the receiver to the Projector then I lose the audio right? The DVI to HDMI from the HTPC to the receiver won't transmit an audio signal, so I would have to run a separate eighth inch to RCA Y-Cable into the receiver on a different input. Can you tell the receiver to get video from HDMI but run audio from a different input?

Correct, DVI does not carry audio signals


On some receivers you can. The 3808 will allow you to set up the input audio and video source for each input.

Does you HTPC not have optical or coax out on the soundcard or mobo? If it does I would use one of those for audio which is the only way to ge 5.1, the 5.1 soundtracks are only carried over digital feeds.

Thanks Jake.

This is turning into a nightmare. I wish I hadn't gotten a horrible head cold right when all this stuff arrived.

So no HDMI works at all. I got the PS3. Ran an HDMI cable from the PS3 to the HDMI 'DVD' input on the denon. I can get sound, but no video...now if I plug the PS3 in using the red/yellow/white cables and put them on the input in the front of the Denon, it works fine with audio and video. I don't know why the HDMI won't work. I went into the PS3 settings and told it to output HDMI, and something must be happening because I get sound...but no video.

Is it because I have no HDMI going out of the receiver, just standard RCA video as an out currently going to the projector (need to go to the store and get LONG DVI/HDMI cable)?

You need to set the input for the DVD on the reciever to HDMI as well. I think the default is component.

You need to take a break. Nurse that cold with a beer, will ya ?
