Title: Bryston SP3 4K passthru
Post by: DRC on 28 Oct 2016, 04:05 pm
Hi
I have not been on this thread for a while and am looking for advice. I have 1 of the original SP3's with Serial no 112.
I am moving to 4K and would like to continue to use the SP3 as it was intended for video pass thru. I see that they have replaced the original HDMI board which was a Momentum Data Systems HSR8-3D around 2015 with the HSR-82.2 HDMI board.
Has anyone upgraded their SP3 with this new HDMI board?
I ask because this new board still does NOT support HDR and is NOT HDMI 2.0a.
I realize it is almost impossible for Bryston to "chase" HDMI's always changing specs. But a few things, especially HDR are critical to get the full benefits of SUHD.
My question is, has anyone used their SP3 with the new HDMI board and passed thru HDR? What errors would I expect if the projector and source both support HDR? HDMI 1.4 does not support Rec 2020 colour space or HDR.
Is anyone aware of if or when Bryston will ever offer the ability to pass thru HDR?

Hi James

Just want to let you guys know the SP3 hdmi 2.2 upgrade was a complete success.

Manage to connect the modified SP3 to our JVC Z-1 (RS-4500 over your place) and it pass through 4K HDR with no issues using our Oppo 203 and Panasonic UB-400 UHD disc players.

Switching between normal Bluray and 4K Bluray HDR content were hassle free, switching between the hdmi inputs of the SP3 were again problem free, maybe just a tad slow for 4K HDR picture to lock but nothing to complain.

Picture performance was brilliant through the SP3 and of course you have the usual brilliant SP3 sound for blurays and 4K blurays all through just a single hdmi cable to the SP3.

Again a fantastic job done for which we will whole heartily recommend this upgrade to our existing SP3 customers.

Best regards,
James Tan

So you can upgrade to 4k and HDMI 2.2 on any version board? I ask as I have a 2011 SP3 and would love to upgrade it but thought I read only the 2016 or later units could be upgraded.

I had this upgrade just done on my SP3. Works perfect with all my 4K UHD sources output to JCV 770 projector.
Bryson turned around very quickly. Could not have turned out any better.wp

Hi James, just to clarify, you are calling this an HDMI 2.2 upgrade. Does that mean that it is the most currently available 4k spec i.e., HDMI 2.0b with HDCP 2.2 or what?

Reference:  https://www.cnet.com/how-to/what-is-hdmi-2-0b/

If I purchase a used SP3 right now can any historical SP3 be upgraded or will it only work with more recent production? Range of serial numbers?

How much does the upgrade cost in US$

Thanks,  Al

Hi Al

From Engineering:


SP3 currently ships with HDMI 2.0 (cant't remember is a or b) and HDCP 2.2

Old SP3 can be upgraded (HDMI card swap) but it is expensive because it involves replacing the rear panel due to a different layout of the input ports on the new board.

It must be HDMI 2.0a as the post above stated his unit was upgraded by Bryston and it passed HDR. :o

I just got my Sp3 back with the HDMI 4k upgrade, Got the Cable TV and the DVD player hooked up and they are running great.

I have a question that I cannot figure out what is going on. Any help would be great as the manual is not going into to much detail. I

 am trying to connect a Apple TV. I used the DVR button and when I plug the hdmi cable into the hdmi 5 input on the SP3 the TV gets no signal and the display on the SP3 shows hdmi5 no, which I assume means it's not getting a signal.

I know the Apple TV and cable are good because I connected the Apple TV through the DVD player, (OPPO 205), it passes the signal to the TV fine.

I really wanted to simplify the process for a signifigant other by having her press the DVR button and Apple TV would come on. But it doesn't work. I can deal with this but it makes it very complicated for her. HELP PLEASE, seems like this should work, does hdmi 5 not pass video signal?

May have been premature in judgement. I'm getting hmdi board failed messages. Now picture passes to the tv via the dvd  player with sound to the tv but no sound out of the sp3. It also will not switch video from the dvd when the cable or other options are selected via the inputs in the front panel. I had them for a brief few hours then nothing :( I have also emailed Mike at Bryston, will post what happens, really bummed.

And does Bryston charge for return shipping?

>>Please keep us posted on the outcome.<<

On it's way back to Bryston tomorrow, still hoping for the best. Apparently the ribbon cable on the hmdi board can disconnect in shipping, not very comforting on a 1k "upgrade". Could explain why the hdmi outputs stopped working but no explanation yet for why the balanced and digital inputs don't work. Hopefully I now don't own a 11k paperweight. I'm beyond bummed

That's for the USB board.  With the HDMI board and a 2011 unit they also have to replace the rear panel which is an additional cost.

This is going to cost at least $1500 if not more.

So it came back, connected it tonight and it now works, I'll spend some time with it this weekend and calibrate it. I am not getting a video signal through the hdmi 5 port for apple TV. I am running a 55 ft hdmi to the tv and it may not pass a deep color signal, gotta dig more, as that menu came up the apple tv set it but then says it gets no signal, wierd. but I have sound and picture on the cable and dvd so I can work with this.

Whoa! 55 feet? I'm not certain that's within the HDMI specs. Seems awfully long.

Whoa! 55 feet? I'm not certain that's within the HDMI specs. Seems awfully long.

There is no specified HDMI cable length, only that to be compliant a cable used for 4K UHD video should be able to transmit at 340MHz.

HDMI.org lists 10m/33ft as a "typical" length before an active repeater or transmission over Ethernet, Coax or Optical cable could possibly be needed.

There are certainly many installations using 50 ft runs of compliant copper HDMI cable that work between many combinations of connected equipment, but certainly not all, and there is a very good chance the cable length in this particular scenario is the problem.

Title: Re: Bryston SP3 4K passthru
Post by: Grit on 23 Feb 2018, 08:11 pm
It could still be cable length. Perhaps the Apple TV can't supply a signal at that length.
Title: Re: Bryston SP3 4K passthru
Post by: jklowan on 23 Feb 2018, 08:19 pm
The cable from the apple tv to the sp3 is only 3ft, the 55 ft hdmi is from the sp3 to the tv
Title: Re: Bryston SP3 4K passthru
Post by: NekoAudio on 24 Feb 2018, 02:46 am
To reiterate srb's comment, for longer HDMI cable runs it may work but you may also want to consider using an HDMI repeater or something like an 18Gbps RedMere or DynamicView HDMI cable which comes with a built-in signal amplification chip. However, I'm still not sure those cables would support 18Gbps at 55 feet.

It is possible the 4K Apple TV requires 18Gbps while your cable box does not, and the OPPO UDP-205 Blu-ray player will adjust its output to match the display capabilities. Which could be why they work and the 4K Apple TV does not. When you passed the 4K Apple TV through the OPPO UDP-205, the OPPO may have been changing the signal to match the display capabilities advertised in your display's EDID. The Xbox One S/X is another device that wants 18Gbps to provide 4K HDR as it runs its UI at 60fps.

Also, your display needs to support an 18Gbps HDMI signal. I think almost all TVs will, but many projectors will not.

So I spent a few hours with it last night. Got it to work, so happy. I'll restart this, the product sounds fantastic, the manual sucks. There really should be some kind of set-up breakdown (screen by screen), even if it was online. I lowered the deep color value from 600 to 100, turned the preset so that hdmi 1 & 2 are always on and I skipped the deep color set-up on the Apple TV. Currently working, listened to various material for about 4 hours last night and damn I've missed you so. I am almost in bliss once again. This has been one of the more problematic system upgrades ever and I am almost there. In the switch something apparently happened to the center powerpoint which will be going in for repair Monday (a contractor screwed into the speaker cable, which had to be replaced but speaker still isn't working). But the sound I'm now getting is almost other worldy. So happy {{{{{BRYSTON}}}}} and there customer support is second to none. I now need to fine tune the TV set-up. This system sounds super detailed so much more resolution on inner detail and about as uncolored sound as I have heard in my home. I was hoping that the Oppo would sound as good as the bcd on redbook so I could get rid of one piece but I'm keeping the bryston it's still much better sounding to my ears, I could live with the Oppo but I'm glad I don't have to.

Current system:

Bryston SP3 - which replaced a SP 1.7 & SPV-1 in November
BlueJean cable hdmi 55ft to TV
Bryston BCD1
BlueJean balanced cable and better cable silver digital cable
Bryston 9BSST

OPPO UDP-205
currently Audioquest  Diamondback/King cobra RCA's & BlueJean balanced cables,
switching to BlueJean RCA's as the audioquest are really loose on my Oppo - soon to be selling the Audioquest

So of course nothing is easy. I took down the center channel and I get sound when I connect that speaker to another system. I get no sound in this system.Trying to figure how to trouble shoot my issue. The amp has all channel lights green indicating they are operating fine. I tried swapping the center channel balanced cable from the amp to the sp3, that didn't work. Ensured that the cable is properly connected to speaker and amp, that is correct )red to red & black to black).

Can I just swap the input balanced cables from the left front/center on the SP3 which works to the center to see if I get sound in the center channel and if that doesn't work it is amp related, correct? this is so frustrating, need a break

Yes you can do that and if you get sound it has to be the Center channel has an issue.  I assume you have told the processor in the Menu on that source that there is a Center present?

Thanks James, I will investigate further, on another day. I will check by switching balanced outputs, then swap speaker wire as it is new and maybe it has a bad termination on a spade. I am at a loss but will do this when I'm fresh.

Could there be a problem with the center balanced input on the SP3 not passing a signal?

Everything looked good when I checked earlier.

At least the hdmi board upgrade is working fine now :)

It could be the balanced out. If you can try the RCA center and see if that works.

Had some time this morning, so the center channel issue came down to the balanced switch on the amp getting bumped apparently last time I reconnected the speakers. Almost everything works as it should and sounds great. Thank you Jim and Mike at Bryston for all you do, these pieces sound simply amazing and your customer service is really 2nd to none. You have a life long customer in me and I'll sing your companies praises to anyone who will listen. Dealing with Bryston is ALWAYS A PLEASURE.

To anyone considering the 4k board upgrade I cannot recommend it enough, it works and Bryston will take care of you if you have any problems, as I did, they make it right and go way beyond what could be expected, great great company.

My last issue might be Oppo set-up related or SP3 set-up related for cd playback. I get sound on dvd's via hdmi, but if I try and play a music cd no sound if hdmi is selected. The Oppo is connected to the SP3 via hdmi cable, analog 5.1, balaced cables and digital spdf.

I get sound on cd's via the digital, balanced inputs, but not the hmdi, anyone got any ideas where I should look first or suggestions on what to look for?

And the last is just a general question, the volume seems a little lower than I'm used to. The SP1.7 that this unit replaced never really saw anything over 50% for volume level, the SP3 seems to be at 67% to get about the same volume level, the amp is not clipping am I okay there or should I start planning out the amp upgrades and how much more power should I consider over the 9Bsst  :)
Title: Re: Bryston SP3 4K passthru
Post by: WillyP on 4 Mar 2018, 09:59 am
Probably the SP3 is not locked to the HDMI input of the TV (red LED is on for the HDMI button). To play music or watch a movie with the HDMI input selected the SP3 will only function when the TV is also on (with the right HDMI input selected is a good idea) so the SP3 can lock. You will see that the red colour of the LED changes to green. If this is too much of a hassle for you then use the balanced or analogue inputs of the SP3.

It can be interesting to find out which unit has the best DACs for CD, your Oppo or your SP3.

My former AV processor always locked on the input signal when HDMI was used. The SP3 first locks on the output signal (to the TV) and then on the input signal (from the Blu-ray player for example). This works for me every time; when the TV is off there is no sound because the SP3 won't lock. For DVD-A and SACD, you have to use the HDMI connection or alternatively the multi-channel output. Welcome to the world of HDMI.

Title: Re: Bryston SP3 4K passthru
Post by: WillyP on 4 Mar 2018, 03:09 pm
I don't use the multi-channel output, but normally when you have chosen your settings for the first time the SP3 remembers it for the next times that you choose the input.

I need some help with HDMI passthru and Apple TV 4K.

Equipment:  LG oled 6e.  Apple 4ktv. Brand new SP3. Apple TV set to 4K HDR. Chroma 4:2:2. Match content range & frame rate on. Switching from SDR to HDR and DV 30hz and back works seamlessly when the Apple TV is connected directly to the LG tv. It is quick and no flicker.

However passing through HDMI input on SP3 Results in a sporadic handshake and therefore, more often than not, no picture. Switching from a movie in SDR back to the HDR results in HDR logo appearing but a black screen. Sometimes just switching on the SP3 and Apple TV results in no handshake with LG tv. Dolby Vision 30hz actually works once the handshake is complete. BUT the only way to get the picture is to leave Apple TV on SP3 on and toggle the LG tv off then on. And this is not always a fix. It can take 5 minutes of fiddling with the sources and components to get the picture displaying on the LG tv. The picture is perfect when ithe SP3 completes the handshake but the SP3 HDMI board cannot seem to cope with changing range and frame rates. It almost seems too slow as the HDMI led indicator goes red then blue then red and again blue. Even switching the LG tv off and on can still result in no picture as the handshake fails. I have tried all 4 HDMI settings in the Setup. No real difference. And I’ve tried changing the Apple TV parameters. Nothing fixes this handshaking problem.
I wondered if anyone has a similar issue as I do. Any suggestions or help would be very much appreciated.
Otherwise I will have to use a splitter sending the video directly to the LG tv and the audio to the SP3 which if it actually even works, defeats the whole purpose of using the SP3 as an HDMI switcher.
I would imagine the SP4 would have the same HDMI board and since that is designed specifically for home theatre an Apple 4K tv would be quite a common video source used with that Processor.
 HELP.

Hi James
I came to see Mike with my Apple TV 4K on Monday to try and solve this problem. We spent time together and he made notes  however we could not emulate the issue as the TV in the room did not accept 4K 60hz HDR. The problem only occurs with the HDR and switching SDR to HDR and starting up with HDR as the Apple TV is configured.
I can clearly see that the SP3 immediately handshakes (blue led) picture flashes up, switches away (red led), loses picture, switches back to HDMI (blue led) but will now not display.

I wondered if any other SP3 or even SP4 users with Apple 4K tv had the same issue. It would be helpful input.

Thanks

Did you ever get this resolved Howard?

Just upgraded my SP3 board: HSR82T, Assy rev: C, uC REV: 50-29

Can get an HDR handshake but not Dolby Vision. My LG OLED will handshake with my Apple TV and my Blu-Ray no problem.

Will try some other things today but I'm guessing the board isn't fast enough to lock with Dolby Vision?
