Official OPPO BDP-83 Owner's Thread [technical talk only] - Page 811

Not a good idea because the Oppo's simplistic digital volume control loses resolution when turned down. Oppo recommends it not be set below 80/100 So, what ever you gain from the supposed purity of the analog signal path is likely to be lost in lower resolution.

Im using the new JVC RS35 But the talk right now is the new Sony 85.

question, if you Reset Factory Default does it goes back to the old version of 0430? is it possible to downgrade version like back to 0430?

No, Reset does not change the version. You can install previous firmware versions; see the links in the first post in this thread.

0430 is pretty old, though. You would give up a lot of bug fixes and disc compatibility.

Anyone missing the audio calibration disk?

Why, do you have a spare?

-Bill

no, i mean has anyone brought the player and is missing the audio calibration? is possible i can obtain from oppo?

You'd have to ask Oppo, they may or may not be out of them.

Is there some particular "calibration" task you need to conduct?

According to the info I have read, when regular BDP-83's are upgraded to the SE quality with the same SE guts, there is no indication on the front that such an upgrade has taken place. Obviously, it is too late to have the front silk screened.

But, IMHO, it would be appropriate (and perhaps help a little with resale value later) IF a small metal badge/logo "Special Edition" were applied to the front OR was included and could be applied if the owner desired. The total cost would be a few bucks at most, depending upon numbers that Oppo ordered.

According to the Oppo site, the 83 -> 83SE upgrade includes an SE decal that the user can choose to apply or not.

You get a decal.

Hello to all.

Few days a go, I sent an email to Oppo reporting audio drop-outs in two movies with Dolby TrueHD. And want kown if somebody hase the same issue.

I have the BDP-83 running the firmware 0925, hooked by HDMI to Denon AVR3808 (not CI) with last firmware to. My second blu-ray player is the Panasonic DMP-BD55 bitstreamed by HDMI to same AVR.

Cars (Blu-ray) audio drop-outs with track English Dolby TrueHD EX
00:01:55 when "Walt Disney Pictures Presents"
00:03:41 when switch the front of three carst to top camera view.
After this two errors, I switch the movie to Panasonic DMP-BD55, and plays without issues.

The Sky Crawlers (Blu-ray) audio drop-out only with track Japanese Dolby TrueHD.
00:13:56 when plane is close to the water and receive second heavy fire from enemy.
If my memory not fails, this is the only place on all movie with the problem, but I dont remember if switch to Panasonic player like do with Cars.

Test's with differents HDMI cables, or HDMI port on Denon was done, with same dropouts at same places.

I must confirm, this drop-outs are only with Oppo BDP-83 in bitstream mode to Denon AVR3808.

Using the player in LPCM none of this issue happen.

Both disk plays without issues in Panasonic DMP-BD55 (bitstream or LPCM)

Regards, Juan

Sorry -- I missed that item - thanks for the correction.

Do you think there will be a secondary market in the decals?

Bootleg decals?

"I only use HDMI, but I got the Special Edition because it costs more."
(Shhhh, it's just a decal...)

Chicks dig guys with a BDP-83SE

The greater question is where to put the decal for maximum audio quality improvements in the player. I propose double-blind listening tests.

I'm guessing on the $1000 power cord...

Got my player back on Saturday and did not receive a decal with the player, but they did change the back plate under the stereo outputs it says "special edition"

Get two decals (check on Audiogon) and put one on the outer facing surface of each earlobe. This way you get the advantage when using other sources devices as well.

However used that way, your listening room guests may not be able to hear all the subtle improvements that you are hearing. So ignore any disparaging remarks they might make.
--Bob

Uh oh! No decal? That's going to cause a stir. Maybe the demand is so high the decals are backordered?

Or I wonder if they decided that putting the wording under the serial port was better for audio quality?


--Bob

Most likely stolen during shipment. The decals are actually worth more on the black market than the player itself. Might want to contact OPPO for an insurance claim.

Yes. You can rest assured that the Oppo digital volume control works just fine. Otherwise they would not continue to include the feature. Oppo has stated that the theoretical reduction in dynamic range is unmeasurable. And it is in fact inaudible, even with the best headphones.

No, they have not. They have recommended to only use it in the 80-100% range, otherwise sound quality will be degraded.

There is no loss of resolution, which is a function of sampling rate. There is a truncation of least significant bits, which results in a theoretical reduction in dynamic range due to the loss of the quietest sounds.

Oppo themselves have said that this metric is unquantifiable (search the Oppo threads) and in my experience (and that of several other posters) it is inaudible in a real-world system. Reducing the dynamic range is the very reason for, and the intended effect of, turning down the volume, so the whole issue is moot (pun intended).

To avoid hearing such remarks, crinkle up the decal's paper backing and stuff it in your ear canals. This also has the salubrious effect of reducing quantization noise.

No, it isn't, not at all the same thing. You can have the same dynamic range at a high or a low volume, volume doesn't come into it. That is, as long as you can still hear the full range and the amplification is linear throughout the range.

Reducing the dynamic range is called compression.

And it's why many cd's sound like crap.

Some time ago there was a little discussion about the BDP-83 sometimes getting stuck in an AR display mode that wasn't correct. I believe it was Bill or Bob who said that just selecting Setup then exiting would often jar the 83 into the correct AR (16:9 Auto mode). This worked. I said I would look for instances where this didn't work. Have to admit I haven't tried very hard since, just done regular viewing and quite a lot of it.

Can the AR be incorrectly recorded on a BD? Or is this a misinterpretation of data by the 83? A recent example is "The Deep" BD (excuse my highbrow viewing, but I was re-investigating the wonders of underwater buoyancy ). The "making of" is identified by the 83 in the info display as 16:9, but it looks correct the way it actually displays as a full-size "regular" 4:3.

Edit: doh, I just realised there's no reason why the original 4:3 feature couldn't have been recorded with the side black bars to make it 16:9, just the way top and bottom black bars are recorded for wide AR DVDs. It's the first time I have seen this with 4:3 on BD though, and I got confused LOL.

How often does Oppo update it's firmware, I think I saw three updates on 3 months. Am I correct? Did I see that?

You can see them all listed, with their release dates, in the first post of this thread.
