Official OPPO BDP-83 Owner's Thread [technical talk only] - Page 77

Could'nt 5.1 24-bit 192KHz DTS-HD MA be a firmware update? Are all 5.1 DTS-HD MA 192KHz?

At risk of diverting this far beyond off topic, I just wanted to add that I couldn't get my airport express to act as a bridge to an existing WPA encrypted network--only WEP. Might have been my incompetence, but might be a restriction of the product--something to look into if that concerns you (not someone "hacking" your OPPO, more that you would have to lower your encryption or create a separate WEP network).

Actually, pretty much none of them are, with maybe a few exceptions.

I'm using WPA2 security with my Airport Express and the Oppo. No problems. The Airport Express is talking to an Apple Airport Extreme base station.

Your issue could still have been a bug of course.

I'm also running the same setup (Apple Airport Extreme/Airport Express) with no issues with the Oppo BDP-83 with WPA2 security using 5.4.1 software.

Indeed, the DTS white paper you referenced confirms the numbers you give. I looked on the DTS website and a brochure for DTS HD essentially reports the same thing. I have an article from a well known & respected AV e-zine that mentions multichannel at 192/24. Hmm... (More to follow, read my next post.)

As for Dolby TrueHD (from their website):
http://www.dolby.com/consumer/technology/trueHD.html
- Supports up to eight full-range channels of 24-bit/96 kHz audio
- Supports up to 5.1 channels of 24-bit/192 kHz audio

Kuro Link was just what Pioneer called HDMI-CEC for a short period of time. They've corrected themselves and now call it by the standard name. The Oppo does support HDMI-Control.

Get the Oppo.

Look at the specs listed for the TrondheimSolistene Divertimenti Blu-ray, on the last page (10) of the pdf.
http://www.2l.no/files/2L50SABD_eBook.pdf

Linear PCM STEREO + 5.1 surround 24 BIT / 192 kHz
DTS-HD Master Audio 5.1 surround 24 BIT / 192 kHz
Dolby TrueHD 5.1 surround 24 BIT / 192 kHz

The numbers for DTS-HD MA somewhat contradict the DTS-HD White Paper mentioned in the previous posts.

I can't speak for Audyssey as I don't have it in my current AVR but I plan to have this feature in my next AVP or AVR. However, I've listened to the Lyngdorf Audio RoomPerfect digital room correction system which is similar in form and function. I too feel that it opens up the sound and reveals layers that get smothered by the room modes. In my book, it's an advantageous trade off.

Yes, the DTS-HD White Paper is old (2007) and incorrect. Newer info from DTS, like the brochure on their "Master Audio Suite" (to create the content) gives the correct numbers (which are the same as for Dolby True-HD):
- Supports up to 7.1 channels of 24-bit/96 kHz audio
- Supports up to 5.1 channels of 24-bit/192 kHz audio

I guess the mixup can also come from the disc formats. DTS-HD Master Audio could in itself be used for more channels/higher frequencies, but the disc formats can't support it. Blu-ray can support 5.1 channels of 24/192, while HD-DVD did only have the transfer rate for 2 channels of 24/192.

Sorry I'm only on page 43, also this is OT...

What is DVD Ringing?

Thanks

It depends on how much you want to tweak, and what is good enough. The controls are pretty fine-grained and you can move them alot without messing up the image. They also perform similar but not identical functions and you can move them independently.

Blu-ray looks ok to me at 0,0, but DVD needs small negative values, which do not seem to harm the Blu-ray image. I've never found the positive range to be of use.

See the FAQ: What are the recommended Edge and Detail Enhancement and Noise Reduction settings?

I use the Buffalo wireless ethernet converter. It has 4 ports to connect your components to. If you pair it with their wireless router/AP it uses a proprietary method to double the speed of normal 11g. It made a big difference in the network performance of my PS3, plus I don't have to worry where I place the console in my rack. Streaming FLAC and video is smooth and clean.

It is the white halo you see around lines and edges in the image. It is partly caused by too much compression when the title is mastered, but also is sometimes added intentionally by the studio as an an attempt at edge enhancement: making the image "sharper".

Sharpening controls on a display or player can also add it.

I'm keeping a list of wireless adapters known to work on the BDP-83 here: Does the player have built-in wireless networking?


Send me any others that have been tested and I'll add them.

-Bill

Thanks Bill...

I have analog cables hooked up to the dedicated stereo outputs and they are fed to the 'CD' input of my receiver. All discs thus far have worked. I haven't tried with the disc in question though.

Volume was up higher than normal to try and see if voices were just faint.

I can't just plug the Oppo into my TV to see if there is sound as my TV is not HDMI, it just has a single DVI input. It's an older HDTV that was first on my list to be upgraded, but the Oppo stole all the $$ I had saved up for the TV

He is thinking the RCA L R on the TV audio.

I have always wondered if any of these products that use the electrical wiring in your home result in any "electrical noise" that could effect the audio/video quality of our AV setups? Many companies are in the business of providing power filters and cleaners; do you think these devices might make things worse?

While the Lyngdorf and Audessy are trying to solve the same problem (room/speaker interaction), they do not do it at all alike. While (the built-in) Audessy is a great solution at low incremental cost, it is nowhere near as effective as the Lyngdorf and does not provide the same quality improvement (but then again the incremental cost of Audessy is a SMALL fraction of the Lyngdorf)

Oppo Europe's website now says "coming soon". Does that mean that the European version of BDP-83 will be released for sure?

5.4.1 is the latest version of Airport Utility software. 7.4.1 is the latest version of the firmware (released last week) for the "N" version of the Apple Airport Extreme/Airport Express.

Just like iTunes, Safari & Quicktime, Apple has a version of Airport Utility available for Windows.

Now back to the real/main topic.

Please contact them and ask them. If they give you any definite information, post it here and I'll add it to the FAQ.

-Bill

It has been saying that for a very long time...

Yes it is a bit of a trade-off. Some of it can be ameliorated by upsampling so round-off errors are pushed out to inaudibility. But the effects in a room are really gross compared to tiny errors in the digital domain which are at the edge of audibility at worst.

Room correction is really a good thing. Add some room treatments to help it out and it turns into a great thing.

I'm looking forward to resolving these audio issues with the new Oppo 83, with its improved audio circuitry. Hopefully.

Regarding the discussion of Audyssey and Lyngdorf and their effects on the audio quality, here's another interesting effect of the built-in Audyssey system. - Using the Oppo 980 and an NAD with Audyssey, there is a substantial attenuation of volume levels at normal volume settings when using Audyssey. For some sources, the volume control on my NAD pre/pro, which has a range of 0 to 100, must be set all the way up to about 97 or 98 (-2 or - 3 from maximum) to provide what I consider normal listening levels. And this is very unusual for my speakers/amps, etc. When using a legacy preamp, for example, I normally set the volume at perhaps 20% of the maximum range. Whether or not this would affect audio quality, it has been my understanding that it's generally preferred to set trim levels such that your average volume settings would fall somewhere near or below the middle of the range, and that you seldom have to crank it up much beyond that middle range. I'll look forward to checking all this out with the new 83 player.

Jim

Jim, Audyssey tries to set a reference level of 75dB at the 0dB level of your volume, or at least it does so in my Denon. Perhaps it works somewhat differently in your NAD???

Has anyone found a "bug" that could NOT be fixed by future firmware updates?

Well, that's exactly what this data signal appears as: "noise". So it does get filtered out by any filter or surge-suppressor, which is why the powerline networking adapter needs to be plugged directly into the wall and not into a surge/UPS.

How would we know? You know, crystal balls just aren't that reliable.
