I'm replacing my Integra DTR-7 that I currently have, it's old and showing it's age and I hope the 30watts I gain plus all the new features like HDMI, Dolby Digital TrueHD, DTS-HD Master Audio are a nice upgrade, I think I'm looking forward to the Audyssey room-correction and equalization the most. I do have a question or two.

1. Should I upgrade the firmware as soon as I open it?
2. Whats the best way to pass my directv and Blu-ray
3. Does this model have a 6 ohm switch or does it automatically switch
I run Definitive Technology speakers that are suppose to be 6 ohms.

Thanks

Based on my earlier posts, Onkyo Tech Support first indicated that the output level for the Pre-Outs was "less than 1 volt but greater than 300 mV", and surprisingly that this information "was not exact". Onkyo Customer Support subsequently corrected that to 1 volt output for the Pre-Outs. However, in discussing this subject elsewhere, there are those who feel pretty confident that the output level for the Pre-Outs is likely higher than 1 volt and may in fact more closely approach 2 volts.

In any regard, I will be trying my set up both ways ... first with just the 807 directly driving all of my speakers, followed by incorporating my 2-channel amp for the RF-LF speakers, so I can decide what sounds better.

The 807 does this too when swithcing back and forth from HD to non-HD. Could this just be the same problem if the commercial is non-HD and i'm watching an HD program? Could it be that I have a 25' length of HDMI cable? It's not the biggest of deals, but can get a little annoying. Thanks.

I am in the process of upgrading my 605 to something that has similar processing abilities and most importantly, multichannel outputs. I am running separate amps for my 5.1 setup and will only be using the avr as a pre/pro. I think I am settled on either the 707 or the 807. Since I don't plan on using the speaker level outs is there any on board feature differences between the 707 and the 807 other than the fact that there are no multichannel inputs on the 707?

Thanks for input...

Thanks

you may wish to see post # 1992 here ....

Is there any way you could send wife/kids out to a pizza place so you could get some peace for about an hour? Then you could really focus ... and run Audyssey, as it will need to be quiet in your room ....

hope this helps

I don't think the pre-out voltage is as big a deal as you think. Its just pre-gain driving the amp and can be compensated by simply increasing the output of the corresponding amps, front L&R in your case. As long as the pre-out voltage is within the same range as your amplifier input specs you should be OK. Using more (or less) efficient speakers would have a much bigger impact on the final SPL than the pre-out voltage.

The problem is that the system is already grounded somewhere else, and there is a slight voltage difference between the two grounds. A voltage difference causes current flow, and so you end up with a low-level 60Hz hum where there should be none. That is what a ground loop is. You could see which piece of equipment is the one introducing the hum, and use the cheater plug on that.

I've had the 807 for about three weeks now. It replaces my old Denon 3801. One of the main reasons I bought it was to be able to connect my Blu-ray player, DVR and cable box with HDMI cables. The Blu-ray player and DVR work fine but when I try to connect the Time-Warner cable box, I get a message saying the the HDMI port is not available and that the HDCP authentication failed. I now have the STB connected directly to the TV (Panasonic 58" V10) with an HDMI cable for the picture and an optical cable to the 807 for the sound and it works fine, but I would really like to be able to use the Onkyo 807's HDMI connections for as much of my equipment as possible. I know that I can use component cable, but HDMI cable is so much simpler. Does anyone know of any way to solve the HDCP authentication failure problem?

Otherwise, all is well with the unit. At first I was getting some very loud clicking as the unit changed soundfields on its own, but that doesn't happen anymore and I'm not sure why. It does run pretty hot, but I have everything in an open stand and it seems to be okay. I used the Audyssey set up several times as I changed speaker configuration and it seems to do a good job. I have noticed that the center channel setting seems a little low but the separation is so good that I can still make out the dialog just fine even with loud sound effects in the surround channels. The sub-woofer level on the other hand is a tad high, but I haven't had any complaints from the neighbors yet.

There were some audio synchronization problems with a couple of recorded shows and some Netflix streaming videos. These problems have also vanished. Perhaps a break-in period was required? I have not tried updating the firmware. Everything seems to be working well so I don't want to take a chance. Besides the update seems to apply to bi-amping speakers and I am not interested in doing that.

Finally, I agree with those who say to take it slow, read and then reread the manual which I find to be pretty decent. (Much clearer than the manual on my old Denon.) So far, I am very pleased with the 807 except for the HDCP problem.

1) From the manual, if you select 1080p as output, it will upconvert any source to 1080p, if needed. I take this to mean that any source that is already 1080p will just passthrough, with one caveat. It does seem to always have the on-screen display available in HDMI no matter which you choose (don't interpret this as it's always on, just when you adjust volume or whatever it shows up on your HDMI-connected display), so obviously it is touching the signal, but perhaps only when it needs to for the on-screen display. I will test tonight to see if BR sources still come through at 1080p/24 (as they did with PS3 connected directly) when it is set to 1080p output. I did check other sources, like Netflix streaming through PSP, and my TV saw the source as 1080p/60.

2)Haven't tried this.

3)I doubt the difference is noticeable, but let's face it, you can upconvert all you want and SD material is still going to look pretty bad on a big screen compared to Blu-ray. DVD's look alright, I notice the PQ difference right when it starts if I had previously been watching HD, but within a few minutes of the movie starting and getting into the story I usually forget about it (whereas sometimes during BD movies I sometimes find myself amazed by the PQ during the movie). I must note that I've been letting my PS3 do the upconverting though, I wonder if the Onkyo then tries to upconvert it further. That might actually be an area for big improvement, I'll try turning off the upconverting in my PS3 tonight. Anyway, if your TV is small enough, or you sit far enough away, that upconverted DVD looks just as good as BD, then you certainly aren't going to notice the difference between different high-quality upconverters like the Faroudja and Anchor Bay. I don't know what size TV or seating distance you have though.

4) I compared the 807 to the 3310 (2310 wasn't available for demo) and based on my listening and the speakers I would be using, I chose the 807 for it's detail and clarity. I didn't see the Denon doing upconversion though, it wasn't really a factor in my purchase.

It looks as if component plus optical is my only option if I want to use the 807 for switching sources. Thanks for your help.

I found the solution to be setting the RC 180 to simply pass the HDMI signal through without upscaling it to 1080P.

The setting is the first in the Setup menu, the Input/Output > for the Monitor.

My Motorola 3416 produces a 1080i signal and I frankly cannot see ANY difference between that and 1080p on my Toshiba 52 inch 1080p capable HDTV. There is simply no visible interlacing at all, period!

Any ideas how through mode is implemented in 807? Does it affect signal framerate? Can 807 pass 1080p 24/50/60hz?
