I think I can scrape by with 32 output channels biggrin.gif .

In my fantasy world I'd combine the multi-toslink with somethng like the exaSound just 'cause.

Exactly. LPCM out for however many channels are detected, remapped and eq'ed just as if it were coming out of the speaker terminals or pre-outs. At this time I would personally prefer toslink or spdif.

I assume there should be somewhere in the R-972 that I could tap trinnov LPCM multichannel, and then effectively use the r-972 as a trinnov processing box completely in the digital domain? Not sure if that would violate any licensing agreements?

IIRC, someone did that to an Oppo player. They tapped directly into the Oppo's internal digital data stream to feed into an outboard box of some sort. Can't remember if it was Trinnov or Dirac. I think Kal Rubinson has an Oppo he had modified to include digital outs for all the channels. That's where I got the idea for the exaSound.

Problem is we all need a cheaper Trinnov box and none exist ;-( . And by cheaper, most of us aware of Trinnov might be able to do low 4 figures but not the mid 5 figures that appears to be the current entry price.

Trinnov. There's a dedicated thread on the 20K+ forum that mentioned the "how" part. It's a vanity board specially made for the Oppo, and has the usual caveats about being a mod:
http://www.avsforum.com/t/1453226/trinnov-mc-set-up-guide-with-ssp-and-jvb-modded-oppo

Note that the purpose of this device is to get a signal in the digital domain TO a Trinnov box, not to get digital output FROM the Trinnov runtime box to an amp or another processor. So I'm not sure what the purpose of a digital connection out would be unless you're looking at doing further digital post-processing to the Trinnov corrected signal. If it's to use something like the upcoming MiniDSP NanoAVR I don't think it's worth the trouble to get a pure digital signal to it unless you're a purist, IMO. The HD units are accessible enough on an analog basis.

post #3095 of 3156

I've had a R-972 for about a year now and will be replacing my fronts with some SEOS kits some time in 2014.  My question has to do with a center experiment.  Currently my set is a 5.1 with a "frankenstein" center.  With the remapping that Trinnov does, i thought of playing with the idea of two bookshelf speakers ("new") flanking the TV and getting rid of the center below the TV to help with dialog.  The "frankenstein" center was a bad idea as i struggle with output for dialog.  

 

Is this completely a bad experiment?  I don't want to waste time on bad experiment.    

 

Thanks..........

I've got a timbre matched line (at least, that's what DefTech claims for what I have), and I was extrapolating from comments I remembered here about why some people don't like 3D remapping. I'm not one of them. But if you're right, it's certainly reassuring if you don't have specifically timbre matched speakers.

As for D/A and A/D conversion being eliminated, it's an advantage in a perfect world. How much it matters depends on whether you've got the equipment to notice the difference and/or your philosophy.

has A4less stopped selling 972?
I should have pulled a trigger when they were selling this for 499 in December. Only if I would have known that my Onkyo-5508 was going to stop working and Onkyo would not respond to my emails for more than 8+ days :-(

Just checked their website - indeed the link to the R-972 on the home page is gone. If you search for "Sherwood R-972", it shows up as unavailable and "New Open Box", whatever that means, on this link:

I picked up a backup unit in December, when I happened to check and figured out from the quantity box that the number of units available was consistently shrinking. When I ordered, I was told by AC4L as follows (personal details and an unrelated question edited out):

Good luck.....I think they left that up in case there were any returns, or they lucked into any A-stock from an unknown source. The only thing is that I would be very cautious of buying any refurbished product from pretty much anywhere; a disproportionate number of the problems cited with the Sherwood in the past two years have been from the refurbished AVRs from the cheapo (i.e. $299) sites.

But if you do luck out and get ahold of a new AVR, you'll find that with some attention to detail, and a universal remote, the Trinnov calibration capability of the R-972 is more than worth whatever learning curve you run into if your focus is sound quality.

One other alternative for you, in the Audyssey world, would be the Denon X4000. It's also got XT32 and would give you at leas the same functionality (you might need external amps if you have more than a 7.2 system). You might want to check with A/V Sales, the dedicated sales arm of AVS, and see if it meets your budget.

This unit is truly the best Home Theater unit I ever owned. For music it's ok but for movies it's the best I've ever heard. Sadly I no longer have a theater room after recent changes may be selling mine.

Hi Augmont,
I saw the manual on the MiniDSP website, and it certainly seems promising.

My first comment is that a device like the MiniDSP line of HD products (such my 10x10) or equivalent can be inserted between a pre/pro and an amp, and provide EQ on anything coming out of the analog pre-outs of the pre/pro. In an R-972 context, that's happening after Sherwood's version of Trinnov does its magic (or to apply primary EQ if you're not engaging Trinnov). I use the MiniDSP mostly for managing multiple subs with the R-972's single sub pre-out as an "optimized" summated sub response when I measure with REW, and to provide additional EQ to get a flatter response for my subs beyond what Trinnov does. I have plans to use it with REW to apply house curves with the Auto EQ for some of the mains, but I haven't done that to date yet. You can also use the MiniDSP to provide active crossovers of a sort, but that's not a need I currently have (yet).

Conversely, IMO the NanoAVR, with HDMI inputs and outputs, would be most appropriate if you have a device such as an Oppo, or another HDMI source, that can send decoded LPCM eight channel audio to it as an EQ device BEFORE going to a pre/pro. It's going to be less useful if you want to go beyond eight channels, with Dolby or DTS options to convert a 5.1 or 7.1 signal to allow heights or wides, as in PLIIz or Neo:X,. That might be a problem because you're now moving corrected responses to replicate a different channel configuration than the one intended when the EQ was applied.

But on the other hand, you're keeping everything in the digital domain, which is attractive. And with a Sherwood or Trinnov box, you can use uniquely utilize 2D or 3D Remapping to take advantage of the extra channels for best achieving the target 5.1 or 7.1 Cinema or Music configuration aimed for by the Remapping algorithm.

Curt may have some thoughts about this as well, and can expand on what I've written or correct any spurious conclusions.

thanks stuart for your thoughts.

 

My initial thought when news of the nanoAVR came out was to place between the PS4 and the R-972 so Trinnov can apply its 3D mapping after but i was concerned with over processing.  

 

I'll wait until reviews and implementations for the nanoAVR come out to see what AVS'ers think of this new product.

Hey guys,
Quick question about using my Harmony remote with the Sherwood. Apparently even running the Harmony with the R-972 as an RF controlled device, I only get that remote to work if it's pointed line of sight, maybe at about a 10-15 degree angle, from the receiver to a distance of about 18 feet. The problem is that I have the AVR on one side of our HT/living room, with the sofa in the back where we'd want to use the Harmony. There's maybe a 12 foot spread between the two, at about a 90 degree angle.

Effectively I can't use the Harmony to control the R-972 unless I'm standing within a narrow range of the AVR, which in practical terms means you have to stand up and walk toward the AVR to get my macros that use the Sherwood to work (one for TiVo, one for BluRay input from my Oppo's optical drive, and another for Apple TV). And I've verified that the Sherwood remote's paired on RF, and that the RF antenna is connected. My Harmony blaster's within about a foot of the receiver as well.

Any ideas, or is the weak RF par for the course? It's more of a niggling thing than a serious annoyance, but it would be nice I could actually use the Harmony the way I intended. smile.gif
post #3107 of 3156
I have a Harmony with RF blaster in one of my set-ups and it works reasonably well. I did set-up the original 972 remote to work in that system via RF but did not know you could set-up the Harmony to do the same thing. The RF function of the main remote stinks so I took it back to normal IR and just have the RF blaster sending my commands with the Harmony. Every once in awhile it does not pick up a command from the RF blaster but it is not that bad.

So I picked up one of the last (actually the very last one) r-972's at a4l last year. Last weekend I got a chance to test it with the surround system. Compared to audyssey xt32 the bass seemed much more prevalent. I'm guessing that is because the bass region is not tamed as well as with xt32? Assuming that is the case, I prefer the flatter bass response. I didn't take any measurements, that was just a subjective observation made using Oblivion blu-Ray scenes for comparison. To that end, I may get one of the mini-dsp's, or try the trinnov-xt32 cascade pioneered by sdrucker.

On a positive note, when I tried out 2-channel music with 3d mapping it sounded great compared to my audyssey solution. The trinnov was actually using the left rear surround with the front left channel, I presume to fill in the reflections that are missing on the left, on account of there not being a wall there. Now that I think about it, I guess 2d mapping would do the same thing? Here is a draft of my setup to give a better idea about the "missing wall".



Before I try out the trinnov-xt32 Frankenstein setup, there is one thing about the r-972 that bothers me, but maybe it shouldn't. When I crank the volume up to +8, I can start to hear an audible buzz when close to the speakers. When cranked to +20, the buzz is easily audible 8 feet away (source was paused or stopped when turning volume up this high). Now, there is really no reason to crank the volume over 0, but I like a low noise system. My denon puts out a hiss when cranked up to +18 (again, without source), but it really doesn't sound as "bad" as the buzz out of the Sherwood. I know this buzz also comes through the pre-amp, because I had an external amp connected before.

What I'm looking for from the community, is to find out if this is standard for the r-972, or if my unit might have a manufacturing defect. Anyone noticed the same thing, or lack of, or willing to test on their system?

Thanks,
Jason

Jason,
First of all, can you give us some details about your system? It's difficult for anyone here to give answers without knowing what kind of speakers and sub(s) you have in your room. (Edit: they were in OP, but not visible on my screen at the time).

Are you using the Flat or the Natural setting (slight elevation of about 3 db from flat @ 20 Hz, tilting to flat at 200 Hz, and a tilt downward from flat in the HF around 5 kHz)? That might make a difference in your bass if you're running Natural. I prefer Natural for music, Flat for movies personally, vs. the Audyssey Reference curve with flat bass for music.

As to the bass EQ with Audyssey XT32 vs. a Trinnov calibration, aside from any issues having to do with single vs. multiple sub handling (if applicable), one reason could be the way that Trinnov handles crossovers. The Trinnov system sets the crossover at the midpoint between the -6 db lowest frequency detected for your mains and the - 6 db high frequency detected for your subs. Depending on the relative capabilities of your mains and subs, are you getting a higher crossover for mains than with XT32? That may actually give you MORE bass depending on how smooth the responses are. Not the predicted ones from Audyssey but what you measure in your room. I would strongly consider measuring the comparative (EQ vs. no EQ) bass response - sub only, left and right speakers + sub(s) - with an OmniMic or REW and a USB mic, for both XT32 and Sherwood's Trinnov. Without those tools, we're just guessing.

Another issue is whether you tend to optimize for the multiple seats, or emphasize MLP. The R-972's implementation of Trinnov is single measurement, while Audyssey XT32 can measure up to eight positions (32 if you have the Pro Kit). Depending on how widely an area in the room you're EQing, and where your measurements are, you may just prefer the XT32's EQ of bass due to the broader area EQ'd overall, all else equal.

I need to make something clear: there isn't an XT32-Sherwood Trinnov cascade. What I have in my system is a Denon 4311 running XT32, and an R-972 running Trinnov that uses the EXT. IN. on the Denon 4311 so that I can employ the Denon as an amp. Those EXT. INs on the Denon 4311 are analog, so there's no Audyssey processing occurring in any form on sources that get Trinnov processing through the R-972. Effectively what I have is two "systems" that get amplified by my Denon: The Denon running Audyssey the normal way and serving as an AVR, and the R-972 on Pre-Out to the Denon 4311's EXT. INs, which amplifies the results from the Sherwood. Think parallel systems, not a cascade. That's primarily to get the Denon's superior amp power, and avoid issues with the Sherwood's relatively weak built-in amps.

Re the Franken processor: that's more about bypassing the less than modern Sherwood audio and video processing, and use to use the SOTA Oppo 103 as a source manager/switcher, sending audio output on HDMI and LPCM to the R-972. The MIniDSP is part of that, as it helps give me not only multiple sub management, and add shelf filters for taming peaks (low end) and avoiding too high a speaker crossover for my tastes on the upper end of the sub response. Also, I can use the Auto EQ function in REW to help provide filters as "icing on the cake" to what I get from Trinnov for the subs. But the MInidSP is a greatly flexible tool in my setup - depending on how I have my pre-outs feeding into it (and which ones), I can choose not only to use my 10x10 HD to manage subs, but also provide some EQ and shelf filtering for my mains above and beyond the Trinnov from the R-972.

DK about your buzz issue, but I don't listen at anything like +20, and at any rate my R-972 isn't serving to amp anything directly.

Still, I hope you like your system as things stand otherwise...Trinnov IMO is worth the hassle, due to remapping helping to provide a much better surround bubble if you have less than ideal standard speaker positionings.

It is not adding a reflection, it is correcting for speaker angles by using the surround speakers. In essence, it is pulling the sound out wider by using the surrounds because your mains may be a bit too close together.
post #3111 of 3156
Stuart,

Thanks for your input. System details are in the pic included in the post, including speaker make/model and positions.

Good point on the natural setting. I think that was the setting I used, but I would guess the lfe was more than 3db hot.

I use a tight grouping on the 8 audyssey measurements allowed by consumer xt32, all within the bounds of the center sofa cushion.

Anyway, you're right, we're guessing, and I would like to do some measurements at some point to see exactly how they stack up. Enough about the bass. smile.gif


My apologies for mis-representing your setup. For some reason I was under the impression you were using both xt32 and trinnov at the same time. Thanks again for the details on your setup.


Regarding the buzzing sound, please understand, as I tried to convey in my post, that I do not listen at +20 either. Or +8. I only turn the volume setting up that high with silence at the input. It doesn't matter if I use the r-972 pre-outs or internal amps; the buzz is there in either case at over +8 on the volume. You could test it out. Turn off all sources to the r-972. Turn on the 4311 and change input to external in. Crank up the volume knob of the r-972 and see if you get more of a buzz than a low hiss.

Out of curiosity, maybe you already posted somewhere, but do you keep the 4311 volume set at 0 when you feed it from the r-972?

If that we're the case then wouldn't it do the same for left and right? Angles for left and right channel were equivalent, btw.

Interesting. Were the angles for the surrounds the same as well?
Maybe Kurt can shed some light on what is happening.
post #3114 of 3156
Surrounds are at different angles , because they are different distances from the mlp (and they are on a perpendicular plane to the one formed by the fronts).

How different is the distance? Is the right surround also putting out sound in two-channel with 3d/2d processing?
post #3116 of 3156
I currently had a big problem when trying to connect to LG PA70G LED projector from R-972 receiver using HDMI cable. Originally R-972 was connected to TV with HDMI output and it's totally fine. When switched to pa70g projector, just no pictures at all. I tried to play HDMI bypass and other settings but all failed. When pa70g projector was connected directly to PC through HDMI cable, it's normal and everything works. Anything in R-972 settings I just missed? Thanks.

Hi Jason

My 972 does the same starting around -3. It's a noticeable hum when no source material is being played. I use mine as a pre/pro running out to my Emotiva LPA1. The only thing I've ever thought of for a reason is in my 5.1 setup, I have one rear speaker that due to room setup is away out of alignment with its partner speaker in both distance and angle requiring Trinnov to squeeze out more volume at a lower level to compensate. But I could be completely wrong on this. I can say that I have to push the 972/LPA1 harder to get the same volume than I did my old H/K AVR330 through the same amp. I've always assumed this had to do with the balancing act it does to compensate for that one speaker and causing that hum further down in volume than you normally would. As long as I don't get much past -5 it's not noticeable with source material playing and volume is enough to be right before the ouch level. Hope this helps.

Hi Ryan,

That's exactly the kind of feedback I was looking for. Thanks for posting.

Meaning simply using DLY+LVL by itself won't get the reproduction of the sound stage will all available speakers captured correctly, since there's no rerouting?. I wonder if Trinnov remapping would work with the "voice of God" ceiling speaker LOL...

LOL all you want wink.gif we'll find out how well it works soon enough, as I purchased the one 972 that came into stock at A4L today, for use in my living room (7.1 in-ceiling setup with DefTech RCS II LCR and RSS II surrounds… single Rythmik F15HP sub). Yes, a proper setup would be much better, but in a tight living room (and more importantly, a room where WAF dominates), I'm already much happier with in-ceiling 7.1 than the soundbar previously in use.

If I'm not happy, it'll probably go back up here in the classifieds in a month or two… although, if trinnov can't make me happy in this regard, I'm not sure what my other options for REQ would be ('voice of god' is not exactly the situation most were intended to deal with wink.gif

With all the speakers in the ceiling, Trinnov is not going to be able to do much in the way of 3D speaker placement correction. 2D yes...but not 3D.
