820 (inside):


Top left corner is where the DACs are.
What I see are three DACs with sixteen pins each.

hello

I'm in the French forum HCFR

I already dismantled the two covers

components Panasonic UB824EGK

1-Condenser 105 graus KXJ - 400V - 47uf

2-Condenser RJG - 16V -1.000uf

6-DACs SEC 731

3-DACs PCM5100A

another great DAC C6306 Made in Chine

there is no AK4493

I think AK4493 is replaced by Made in Chine

Thanks for opening your player and sharing with us...PCM5100A x 3

Those are low-cost DACs, roughly couple dollars each.

I first suspected Texas Instruments DACs; that was the three DACs that I couldn't make up.

- SEC 731 are not DACs.
- C6306 I thought it was a Cirrus Logic DAC but no such number I could find.

So, the 820/824 has eight analog RCA audio output jacks, but only three stereo DACs. One stereo DAC is missing, or ...
___

And there is just no way that they would put a premium AK4493 DAC in this machine like they did in the high-end player...the 9000.

Anyway the 820/824 is a more budget friendly player. It's not build like a tank either. And with time it will be on sale for less money, like most regular players out there. ...Like the 900 for example.

It's a good time to be alive, and feel young in the heart and spirit.

Un petit peu


usually my PC translates all pages

No, Cirrus Logic, C6306 Made in Chine

I already think about the Pany UB9000

seeing my 824 here in Portugal

will not exist for sale in Portugal any of them neither 820 nor 9000

Panasonic is no longer represented in Portugal

[LordoftheRings]

Everything is made in China nowadays...Oppo, and soon Harley Davidson.
I don't know what the C6306 is, yet.
Panasonic OLED TVs are not available in the USA.

* I'm checking the French audio/video forums @ this moment; my mojo (best area of communication). I'm curious about the 820/824 and 9000 internal guts and all that jazz. I'm also looking for other stuff of interest. If something new comes up on the 820 and 9000 I will include it right here in this thread.

No;

the HONDA bikes are made in Japan



OK

I'm waiting for more news

[LordoftheRings]

I am pretty sure that there are four TI PCM5100A DACs in the 820/824.
One that I couldn't see has to be on the top left of the analog stage of that circuit board.

Now on to the 9000 ...

Lol, good one...I completely forgot about Japan.

So I'm in the UK for business and since we're doing encoding and authoring for UHD BD titles, I had to pick up a European variant UHD BD player (yes, I know it's a region free format, but you can still read country codes in some cases so it's best to have a bona fide EU player around for EU clients). Plus, my multiregion standard BD player converts all 50hz content (for what little there is) to 60, so I wanted a player that output PAL DVD and 50hz BD content natively.

So I bought a Panasonic 820 from John Lewis. I'm very happy with it so far. It's a typical Panasonic player - slower to use than the Oppos but excellent quality. The build quality is excellent as is typical for Panasonic products also.

I like their take on chroma upsampling in theory, although especially on TV sized screens, the effects will be very hard to discern with most live action content on BD. It's potentially much more useful for upscaling DVD's 360x240 or 360x288 chroma channels than it is for BD. It's been noted that what they're doing to Cb and Cr can leave colored ringing, most visible on test charts but I've found lowering the Chroma sharpness control basically gets rid of it, but it'll almost never be visible in content anyway. I need to do more tests with that to see if that introduces any other collateral damage. It's mild either way.

One weird thing is that it appears to have CUE when playing 480i (and presumably 576i) content from BD (not DVD). All that really affects is some old SD bonus features that are encoded as SD on certain BDs. SD content is rare as hell on BD in the West so I'm not losing sleep over it. I've tested some 25fps content encoded on BD as 1080i/50 with 2:2 and it doesn't have CUE there, but will need to see if it affects pure 1080i/50 or 1080i/60 video - hopefully not.

If it does, the European firmware has a "Bandwidth Limitation" menu in the picture settings which lets you apply vertical and horizontal lowpass filters to the luma and chroma channels. This is applied after deinterlacing but before scaling, so doesn't mangle interlaced content. If seeing CUE with SD on BD bothers you, you can just turn up the vertical chroma filter and essentially hide the problem. As I said when I reviewed the European UB900, I'm not sure what the intended use of this menu is - this is the first use I've found for it. If I recall rightly, it isn't featured on the US version.

The usability isn't quite as good as Oppo's: like most players, certain settings can't be adjusted during playback, although the critical image quality adjustments can. Also, there's no jump to time feature that I can see, so you'll have to rely on the chapter stops on the disc and the FF/RW functions. Chapter surfing and scanning are quite sluggish which I see often on Panasonic players.

As usual I'm impressed that Panasonic are identifying potential system performance gaps and making actual improvements (HDR Optimizer essentially performing tone mapping in the player rather than the display). Looking forward to doing more testing with it. As is typical with their products, there is no behind-your-back guff like noise reduction going on (the last Samsung players I looked at applied noise reduction to the chroma channels without having any off switch).

I also really, really like the Edge Correction feature which can be clicked up a notch to remove ringing caused by the scaler.

Very happy with the UB820 so far. I'll do more testing later and pass any feedback on.

As good as the early reports sound, I would like more of your feedback on this.

David,

Extremely detailed report about some features of this new player.

I'm no pixel peeper or hardware maven, but I look forward to GeoffD's reaction to the info you've passed along. Job well done, just wish we had info like this on some of our other hardware!

[panasonicst60]

Will this player have HDMI 2.1?

[wesslan]

No since it's out in europe with 2.0, if they don't change it all for US but unlikely.

Although, now, Tyler may not be too happy with me for pointing out the fact he’d made an error in his LUT calculation.

Firmware update for 820/420. HDR10+ is available, but no sign of Dolby Vision yet.

hello,


But how do I proceed to download on 824?

Lol what are we supposed to do with that?

Do you know if the Youtube and Netflix apps have been added now?

[pathfinder2810]

I think they only added the item on the Hdr 10+ on / off menu. For the rest, no other striking news .. All as before

David, that was a compliment ^. You’ve come quite a long way (http://www.fidelityinmotion.com/) since last I was called in to apply some constructive criticism to your analysis - https://forum.blu-ray.com/showthread...24p#post352780
