HW-K650 and Two R1 Wirelss Speakers in 5.1 With KS7000 TV

First Poster

Being reckless, I updated my UE49KS8000 to the latest firmware.  The only change I have noticed is that if the speaker system is not grouped, my R1's now appear when I scroll through the Select Speaker option in the TV's menu which I can't remember seeing previously.   Is that  correct or am I imagining things?

Hi

 

Just go back into wireless speaker management and re make the group. If they aren't grouped they will indeed show up separately.

Hi Not Samsung.

 

Firstly, I don't work for Samsung. I am on here trying to help people and also trying to get help myself.  The way you write your messages seems to assume that I have an obligation to answer and fix all your problems. 

 

I haven't dismissed any of your problems though.  Please let us all know your exact set up including what TV, soundbar and rear speakers you are using so we can try to help you. 

 

The reason I said that your TV can't accept, passthrough or output multi channel PCM is because none of our Samsung TV's can. Neither can our K650 soundbar. It's just a matter of reading through the manual to find that out as it's not in the specs.  

 

In regard to Dolby 5.1 tracks being a bit quieter over all than a stereo track. Yes it is for me. But, I mean overall. So when I turn it up a bit all the channels including the rears come up and remain balanced with the overall system so in that respect Samsung gave managed to fix that issue for me and quite a few others on here.  I'm sorry if you felt I had dismissed any issues you may be having. I can only tell you what works and doesn't work for me. I do my best to try to help. I found the optical cable work around that got us by over the last few months.

Hi Lee,

 

 

Never claimed that you work for Samsung. 

 

My setup:

See my previous posts,  the ones you responded too - they have my exact setup,  tests,  results and questions.

 

My rear M3 speakers hardly make a sound when playing Netflix DD5.1 via Samsung TV when Audio Output =Dolby Digital on my K650 (all 5.1 speakers connected via Wifi). 

 

That's the exact same issue listed in this thread.   What am I missing here?

 

How do you know that no Samsung TV can output multichannel PCM over Wifi from an internal TV source (such as Netflix)?

Hi all

You can definitely send standard DTS over optical, I did it for many years. I believe that if you are connecting to the soundbar via WiFi from the TV then it probably doesn't mater if you select DD or PCM as that setting seems only to be if you are passing the sound through the TV via Hdmi or optical. You definitely cant pass multi channel LCPM/PCM via hdmi or optical. The signal from your source would first have to go through a dedicated reviever and then to the TV.

Are you now saying that my TV can output multichannel PCM if I connect the K650 (& 2xM3 rears) via wifi? Just not if it's optical on hdmi?

 

So, if I play a Netflix DD5.1 from my TV app,  then it is irrelevant if I select Audio output as PCM or DD?

 

I tried that,  and the PCM seems to yield pseduo 5.1.  The DD setting results in a lower sound level and rears almost non existent.  This is ironically the same result if I change the K650 to connect via optical or HDMI (and obviously keep the 2 rears on wifi connected to K650).

 

I'm lost now.  

 

How do I get DD5.1 with the K650 and 2 x M3's?

Lee,

 

Are you using Wifi to connect the K650 and rears to your tv?

 

If so,  playing a Netflix DD5.1 on your TV,  do you get 5.1 regardless if you set TV Audio Output to PCM or DD?

How do I do a factory reset on the K650?
Navigator

Hi

 

Yes a factory reset is worth a try. On the end of the soundbar hold the volume up and volume down buttons in at the same time for a few seconds. That should reset the soundbar. I will habe to do some testing with Netflix later to see how well mine is working. I seem to remember it being ok but I will test it again.

I have tested my system, UE49KS8000 and HWK650W and 2 xR1's since updating all to the latest software.  It is true that the volume level playing PCM format  is significantly higher than when Audio is set to PCM.  However, having used the Fraunhofer EBU Tech 3304-4.1 BLITS test file, played from a USB input, PCM does not render distinct 5.1 over Wi-Fi.  With the TV's Audio Format set to Dolby Digital, on the other hand, fully separated, well-balanced channels are evident, comparable to the optical workaround.   

 

Having said that, the PCM rendition when playing content  from SKY or Netflix, seems to me more immersive and "in-your-face" than DD which  seems to lack volume and punch overall, unless the sound control is cranked way up.   If I remember correctly, that was the case with the optical work around too before the big fix.

 

So by updating the TV firmware, I don't think I have compromised the big fix! (Breaths a sigh of relief).

I have also done the TV firmware update and can confirm the surround over WiFi still works fine - phew !!

 

Just to clear up some confusion from earlier posts:

 

LPCM vs PCM - In the context of our soundbars these are exactly the same thing.  Strictly LPCM stands for Linear Pulse Code Modulation which is the type of PCM used for WAV format audio. (Another type of encoding is Log PCM but that is not used for WAVs)

 

DTS vs DOLBY 5.1 - The HW-K650 can process Stereo WAV files and Dolby 5.1 Surround files.  It cannot process DTS surround, nor can it process Dolby ATMOS 7.1 or other higher channel count formats.  But some DVD and BluRay players can be set to recode a DTS output into Dolby for compatibility.  The DTS absence in the K650 is simply a cost saving as the DTS technology requires a licence fee payable by the manufacturer and ultimately the end user.

 

"But I hear surround when I set the TV to PCM" - Yes and No...

The K650 processes true discrete 5.1 channel surround when fed with a Dolby 5.1 bitstream.

When fed with a PCM stereo (2.0) source it synthesises a surround field from the stereo information and presents this on the rears - the same happens if you create a surround group in the multiroom app and play a stereo audio track through the group.  The front left and right on the soundbar will exactly reproduce the intended L&R Stereo, the centre channel will be created from the Mono component of the stereo source (mainly dialogue) and the sub channel will pick up the low frequencies from the stereo source.  Much of the time this sounds really good but it is not the surround mix as intended by the film producer.

 

Volume settings - It is likely that when playing Dolby 5.1 sources the volume level will need to be increased as compared with Stereo sources.  This reflects the fact that each channel is being fed discretely.  But also check that your offset in the TVs wireless speaker manager is not too extreme - if the soundbar is still set low it will exacerbate this.  Based on streaming the "Spooks" movie from Netfix last night I was getting excellent surround and clear dialogue with the Soundbar set in the middle position and the rears just two clicks higher.

Not true that hw-k650 cannot play dts surround. If I create surround setup with my bluray players multiroom link settings DTS MA 5.1 speaker assignment sound check plays correctly with usb stick plugged into bluray player.

 

 If you look at audio specs for hw-k650 on samsungs website it says dts 2.0 but if you click on the question mark next to it it says dts 5.1 surround sound.
