Can Trinnov be applied to analog inputs for music listening?

Man, I have got to stop spending time here at AVS. Yet another deal that seems just too good to pass up, so I ordered one to go in the bedroom system. I already have a Denon 4311 in my main system.

Hey guys and I hear ya!

As a previous owner of a P-965, I've been following the R-972 since it was originally announced. With the shaky launch that it had, I ended up passing and purchasing a Onkyo TX-NR1007 for my main system and it's been working out well...for now. Many owners are reporting HDMI board failures that are just out of warranty.

I figure the R-972 could replace it or make an excellent secondary system in another room. Can any other 2011-2 receiver come near it's SQ at that price? No doubt that it loses on the bells and whistles. But all I care about is lowering the lights, putting on a Blu-ray, reclining my chair, and taking in (hopefully) that beautiful surround sound from Trinnov.

The only thing I wish it had was Network control. I have to purchase a Network <-> RS-232 device to use with the iRule remote app. Other than that it could work out very well for my setup.

Conrgats and looking forward to hear your experiences!

Since there is only one sub output, I'm assuming it's one, but I'll know for sure by this time next week.

BTW, these A4L units are new, not refurbished, with 3 year warranties, all current updates including HDMI 1.4 and even have free shipping!

Went ahead & ordered one. Figured its worth the risk at current price for brand new unit with full warranty just because of Trinnov. Keeping my fingers crossed hoping that the unit functions without any glitches. Sales rep told me that the units have latest firmware 1.47v.

Ah, Trinnov!

I just ordered one, too, at this price it seems like a steal.

Can someone tell me if I can have a Trinnov eq setting for Zone 1 (7.1) and a separate Trinnov eq setting for Zone 2 (Stereo, separate amp)?

Also, I just set up my speakers for Front Height -- what would this sound like without Dolby PL IIz?

The current price of the R-972 looks very interesting. I see mention that Trinnov has issues with calibration if the all the speakers are not positioned properly. Due to my room layout (open on one side) I had to place my surrounds on the ceiling behind the MLP. Will Trinnov have issues with the surrounds in this location? After doing a Trinnov calibration and one checks the speaker levels with a SPL meter can the levels be changed? In other words if the center channel level seems low for a specific movie can the level be raised?

I have di-pole speakers mounted on the ceiling just behind the main listening positions. Trinnov in the R-972 has no problem finding them.

Individual channel levels cannot be adjusted when Trinnov is engaged. In my experience intelligibility is so good with Trinnov engaged that you will find little reason to want to adjust it.

Jeff,

Thanks for your thoughts. I am very tempted to give the R-972 a try. Did Kal ever do a review of the R-972?

Thanks, for the link, adude.

But, unless I am missing something, it just states that t has three memory settings for three seating positions.

-- Does this mean that I can calibrate my Stereo setup in my Stereo room as Memory 1, then calibrate my 7.1 setup in my TV room and save it as Memory 2?

-- Also, what does Trinnov do with Front Heights? Does it even work with those?

Ryan,

The link was in response to Bill's post asking for Kal's review.

As for your question about Front heights: This receiver does not support front heights. It lacks the PLIIz mode or any other DSP mode for front heights. So, obviously, Trinnov will probably not do anything for those. May be StereoJeff can add more.

Thanks gain, adude.

Yes, if StereoJeff can chime in on my questions, it would be much appreciated.

I wonder if there is a possible set up with two sets of fronts (one positioned higher than the other)? I really have come to like that much better than rears.

adude,

Thanks for posting the link! After reading the review I'm not sure I'll get the R-972. Not that Kal's review was negative just that a few points he made especially the fact that audio formats are not input specific. This could have changed with a FW update though.

The setup with two sets of fronts with one higher than the other is very effective with Trinnov. I am not sure about the answer to your stereo room/7.1 room question. In theory I believe it could work but Curt would be the go-to guy on this one.

Well, I ordered one too, based on reviews and this thread (the last 3 pages). Hopefully the latest firmware is stable and the nagging issues are fixed. It will be interesting.

Thanks, Jeff! I am so glad to hear that two sets of fronts will work with Trinnov.

How would you set this up?

Analog in: works fine with Trinnov correction.

Speaker placement:
Yes, you can do height, or wides, as an example. Technique is to place speakers where you want more spatial definition, then calibrate. As we have more spatial acuity in the front, it makes a lot of sense in most rooms that are not long and narrow to setup a typical 5.1 array, then use the extra two channels for height or wides, or to fix a spatial problem. An example of this could be that there is a door, right where the left channel should go. The solution may be to place a speaker on both sides of the door, then have Trinnov correct the image. Same with height. If you have a low center, this can be off set by placing another speaker high. Requires re-calibration any time speakers are moved. When doing this, experiment with SPTL set to 2D and 3D for best results.

Two Trinnov calibrated rooms.
You are onto a great option, but it's limited to 5.1 and stereo as is, or 7.1 and stereo with adding a speaker switch, such as Niles SPK-1. I do this one- 5.1 + 2.1, without a speaker switch box. Only one calibrated room will play at a time, and cannot be done using Zone 2, which is designed for simultaneous use of more then one zone.

Here's what you do for 5.1 room + stereo room:
Both rooms can have subs, or not. Connect 5.1 speakers. Stereo will be connected to remaining amp channels. Leave multiroom OFF. Calibrate the 5.1 room as normal, with the stereo room speakers (and sub, if there)disconnected. This becomes memory 1. Then disconnect the 5.1 speakers, while connecting the stereo speakers to the remaining channels not used in the 5.1 configuration (don't share output connections with other room, except for the sub output). Run the calibration of the stereo room, store this in another memory, say 2.

Presets select rooms: To select which room plays, assign in Input Setup page 3/3 to the Trinnov memory for the room, in this case, POSITN 1 = 5.1 system, POSITN 2 = stereo system. Then set SPATL to AUTO, 2D or 3D. When you select the preset, the room will automatically be routed and corrected. Sub: if you have a sub only in the 5.1 room, all switching is automatic. If you have subs in both rooms, the sub output is shared, so only the subs in the room where listening should be on. Sub switching may be automated using a triggered switch box.

If you want quickly change the room an input is assigned to, you can do it using the Setup > /QUICK/ADJ. If you make a change here, it will be remembered by the system.

Here's what you do for 7.1 room + stereo room.
Implementing a full 7.1 room and stereo Is a bit more complicated, As it requires a speaker switch box, such as the Niles SPK-1, that uses the trigger output to switch between speaker pairs. A manual box can be used, with the downside of having to manually operate it every time you change rooms. You would follow the steps above with the added step of switching a par of outputs from the 7.1 room to the stereo room. See the 972 manual on assigning the trigger.

Two 7.1 rooms. This could theoretically be done using speaker switch boxes, to play one room or the other. Why you ask? I do a form of this between two rooms, one a dedicated theater and the other the main gathering area in my home. The theater- for movies, the gathering room- for listening to music in surround.

One benefit of Trinnov correction is that it works well on stereo speaker pairs: the correction uses the most sophisticated method used in correction used today: both FIR and IIR filters on all channels- resulting in full range correction on large speakers.

Good to know that Trinnov works on analog inputs also. That means its extra A/D & D/A conversion but it could be worth it. I just have to make sure I don't select pure audio/direct mode for stereo analog inputs. Wondering if Trinnov works on multichannel inputs also. My room is 22'x13' with angled ceiling in the middle therefore figured that Trinnov could do its magic by properly remapping speakers in a long narrow room. Audyssey works in my room but not to my complete satisfaction.

Hi Curt!
Can Trinnov in R972 equalize/correct 2 subs at different distances? Would raising sub volume at the sub amp after Trinnov correction cause problems with room correction? Can Trinnov be applied to multichannel analog input also?
Thanks,

vinodk:

Trinnov will not work on the multi-channel inputs as the R-972 only has A to D converters on the front L/R channels.

While the R-972 has only a single subwoofer output, I often eq'd the acoustic sum of multiple subwoofers and was always pleased with the results.

Thanks Jeff. Atleast I can use Trinnov on 2 channel analog inputs & perhaps do some post processing. My concern with 2 subs that are not equidistant is time alignment. I am hoping Trinnov can accomplish that. I will give it a try.

Interesting. In that case, I may put this AVR in my main system and use the Denon 4311 in the BR system since I do have a quasi-full range pair of towers in the main system (Revel F12s).

Thanks for the great info. I have much to learn about Trinnov, but I like what I'm reading about it so far, and since it looks like the proposed Outlaw pre-pro with Trinnov is still as far off as it ever was, so this unit may be it for the foreseeable future.

Good to know, thanks. That helps with my main reservation about this unit.
