No interest vs using the dual output of your source if you have only one 4K protected source.


Such a huge fail for ALL AVR manufacturers this year...


Keeping my Denon 3311 until they get their act together and offer HDCP 2.2 on all inputs / outputs and HDMI 2.0a speed.
In regard to Onkyo I would be more concerned about why they dropped Audessey and down graded their amp rating to THX select from THX ultra

that points to a downgrade in sound IMO....no matter what "K" you are looking at

Never-ending saga: Storied brand gets bought by conglomerate; cost-cutting campaign soon ensues; product substance undergoes extraction in small incremental stages; product managers rationalize moves as necessary to remain "competitive" (and to keep their jobs).

I believe its supposed to be due to a lack of processing power onboard.

Take Anthems ARC for example, it needs to be run on a laptop as its more processor intensive, seems the Onkyo couldn't handle Atmos and full-on Audyssey internally.

To be clear, Anthem's ARC "solution" is computed on a PC, but the actual ARC processing happens in the SSP.

Exactly, this is also the way Audyssey Pro works as well. It comes down to speed of crunching the data which is FAR faster on a PC than it is in a processor.

Yep, I agree with that, but not certain where I read this - it was said that the processing power of the Onkyo couldn't handle Audyssey and Atmos processing at the same time, it could only do one or the other?

That may be incorrect, but it was put forward as the reason Audyssey was dropped by Onkyo.

It is unclear why Onkyo did or didn't do anything and without something officially from Onkyo I think most of what you hear on the forums is speculation. Ultimately I doubt Onkyo will respond in any official way and will probably state that their solution is every bit as good as what they had before. No manufacturer likes to shoot themselves in the foot by announcing their new stuff is a scaled down version of their old stuff.

The only thing for sure is that Onkyo's AccuEQ is developed by Dolby for Onkyo...based on Onkyo training in Canada.

but it is a downgrade.....going from THX ultra to THX select is a downgrade

though It seems that the number of matrixed channels is more important than sound quality is to many consumers

to be clear
The Anthem products are in a different "neighborhood" than any of the Asian manufacturers

It is unclear what THX select even means in terms of a processor. For an AVR it has to do with the power output and room size. This could be an issue depending on load, but it also may not be. Even if it didn't have enough power for the application you could always increase that with an outboard amp.

Better yet get speakers with a built in electronic cross over and amps designed for each driver. Do it right. The era of passive crossovers and huge big amps to feed each speaker's passive cross over is over. Do what the pros do. At most you need a good audio and video processor and even then you can get surprisingly good audio processing by using just the line level outs from a very cheap receiver.

Very good point, Mark. I have Mark Seaton Catalysts for L/C/R, and a Seaton SubMersiveHP sub, all of which have their own internal (and ample) amps. The only thing I need the for amps in the AVR (and elderly Onkyo 3008) is for 5 surrounds speakers, very light duty.

Shooting from the hip Mark?

I would guess the "era of passive crossovers and huge big amps to feed each speaker's passive cross over is over" is far from over.

Amplified speakers require an AC outlet at each position; that or a lot of extension cords lying around. With Dolby Atmos and the advent of increasing channel count/positions active speakers become even more difficult to install unless you're working with a clean sheet of paper.

I think it's safe to say that passive speakers and and big amplifiers are going to be around for a long time.

I also dare say that the speaker probably won't last as long with a built-in amp either. If the amp goes dead... there goes your speaker... unless it has a passive input workaround. Hopefully, there are still spare parts available if it dies after your warranty period is over.

Listen up, studios! Just say "NO" to DNR and EE!!

I designed my theater for power at each speaker location and the coax feeds to each speakers have adapters so they can be converted from line level to speaker level. I took a lightening hit that several damaged two of the amps but they were fixed by an independent shop. Of course nonpowered speakers and passive x overs and big amps will live on. But the pros use self powered and line level feeds. Obviously top level execution is possible using these methods and they are the most popular. But if you are truly serious, active cross overs and amps designed to drive the specific driver are the way to go.

I use active speakers for my LCR's, but passive for my surrounds. Rather than the amp in each speaker, I have my amps in my rack.

The cable is just high quality quad shield. The adapters screw onto the standard coax termination. One set has an rca and the other two wire spades. the product was sold by Music Interface Technologies. Remember non of the speaker terminations for such things as sides or rears would carry much power. all the subs are line level for the most part. Come to think of it, I do have two folded sub transmission lines in ,y ceiling weighing in at about 300 lbs each and they do run off plate amps in my rack. These I think are hardwired with speaker wire.

I think the point GetGray was alluding to was the wire gauge.

Most coax is around 22 gauge, maybe 18 gauge at best. Probably not the best approach for speaker wire considering the length of wire runs in most hometheaters.

Not so much about power needed. More about impedance and damping factor.

I know quite a bit here gentlemen. Trust me. I would not use this for a high quality 2 channel system. But its surround sound and certainly for line level its more than sufficient. Syrrounds are small in size and power requirements. When hardwiring a customers theater, i use a minimum of 14 x 4. but damping factor is really not an issue. The power draw for surrounds for the most part is minimal . And our concern is not with dc impedence . We are dealing with rather low voltage AC. The network design to make quad carry enough power at speaker level is not brain science. Your passive cross over speakers presents problems fior most home theater amplifiers. But they work and they sound great. Its hard to really screw things up because of spkr wiring. its really eact to not use good room design or no or little ascoustical treatment of the wrong treatment in the wrong spots.

They are talking about the cable being used as passive speaker wire, since you said it has spade ends.

Mike. That is intuitively obvious to me and I am far more than a casual observer. You are using a relatively small guage wire, Shall we discuss the AC impedance of the coax cable and its relatively high capacitance. Its needs a network box on each and to make it at all high level suitable, Its does not need to be low guage number particularly because it is not moving a lot iof air. It ain't used for subs but once again it does make a great line level sub cable. There the network boxes do little except provide the right connector.

Well, if discussion were limited to new updates on the BR4K, the thread would probably die, so those of us who come here to see what's new, and there is nothing, we just begin yaking about something more relevant while waiting, kinda like chit chat in church before the sermon begins.

One recent 'event' that IS related to BD 4K/UHD is ITU-T Study Group 16 (SG16) just finished up a meeting last week in Sapporo, Japan where they were considering an extensive amendment to HEVC. The already approved h.265/HEVC standard (from early 2013) only has basic support for 4K/UHD and extensions to that standard are necessary to include such things as support for 60Hz refresh rates and 12-bit depth. It is widely believed the baseline codec for BD UHD is going to be HEVC and the updated HEVC version is necessary to satisfy the needs of BD UHD. Going into the recent SG16 meeting the goal was to reach an agreement on the proposed standard that incorporated the extensions to HEVC. If approval was reached then the updated h.265/HEVC standard will hopefully be approved and published by ITU-T within the next couple of months. Also I heard that Sony was pressing SG16 to get the updated HEVC finalized ASAP because they want to get the design for the new HEVC chips finalized so they can get them into production for planned products (hopefully including BD UHD players). The meeting report from the Sapporo SG16 has been posted on the ITU SG16 web site but only members can download a copy. Hopefully we will get word soon if the extensions for this update to the HEVC standard have been finalized, or if it's going to take another SG16 meeting to continue work on it. Based on past history it appears SG16 only meets 3 or 4 times a year so my guess is they would only fit one more meeting in during 2014.

Good News - HEVC update approved

The executive summary has been released from last week's meeting of ITU-T SG16. The extensions to HEVC have been approved ('consented' in ITU terminology). This removes one technical roadblock for getting the BD UHD spec. completed and allows the manufacturers to move forward with producing the HEVC related hardware/software that will used with BD UHD.
(full text of exec. summary is at: http://www.itu.int/en/ITU-T/studygro...ults-1406.aspx)


Below is extracted directly from that summary:

"Video coding: The 2nd edition of ITU-T H.265 HEVC was Consented It includes three important types of extensions of HEVC coding capabilities, that will increase the quality of compressed video and better user experience:



1. Format range extensions of HEVC, known as RExt, adding improved colour representations. RExt includes support for higher bit-depths and enhanced chroma formats, including the use of full-resolution chroma.

2. Scalable extensions of HEVC, known as SHVC, enabling better performance for dynamic video streaming on networks with varying transmission conditions and other scenarios involving multiple bit-rate services. SHVC adds support for embedded bitstream scalability in which different levels of encoding quality are efficiently supported by adding or removing layered subsets of encoded data.

3. Multiview extensions of HEVC, known as MV-HEVC, as the first native support for 3D video encoding in HEVC. It provides an efficient representation of video content with multiple camera views and optional depth map information, such as for 3D stereoscopic and autostereoscopic video applications.


Conformance testing of image and video coding standards: A pair of new specifications that are used for conformance testing of ITU-T H.265 HEVC video were consented at this meeting:
  • · ITU-T H.265.1 "Conformance specification for ITU-TH.265 high efficiency video coding" (New) [TD 286/Plen]
  • · ITU-T H.265.2 "Reference software for ITU-T H.265 high efficiency video coding" (New) [TD 287/Plen]"
___________________________________----


So among other things the 2nd edition of H.265/HEVC includes support for increased bit depths, up to 4:4:4 chroma, and 3D. The full set of extensions/enhancements will be documented in the actual standards document when it is published and will include such other enhancements as support for higher refresh rates at 4K/UHD resolution.
