Sherwood R-972 User Thread - Page 42

I'm receiving my R972 this Friday! Any tips guys? Something I should start reading on?

The curves only affect the sub level/gain. They do not affect the full channels. You can get the EXACT SAME EFFECT by changing the trim of the sub. It's just harder to to it manually and get it right.

Good to know.

No need for me to install the files and re-do everything then.

Thanks for all your support on the threads and the notes.

Has anyone had luck converting the remote to RF mode? I've tried several times following the instructions in the manual with no luck. Antenna is connected, I'm changing the remote to RF mode and then holding down the two buttons on the unit to scan, but it is not picking up the signal when I'm pointing the remote and pressing ENTER. Any ideas?

In that case it might be worth it to do separate measurements using the +3dB and +6dB curves, storing them as Position 2 and Position 3 (respectively). Can be done during initial setup, since there is no need to move the mic between measurements. This way, you have all three curves at your disposal; can even assign them to different inputs (keeping all other parameters the same) to easily bounce between them.

Sanjay-

I don't recall if the positions get erased when the +3 or +6 files are loaded. Let us know if it works... and I'll make a note in the User Notes.

I actually thought about that, and I don't think it will work as you can't select which curve to use, and everytime you load a new curve, you have to reset the unit (at least that is what the instruction says), so you will lose your previous cal.

I was wondering if anybody was having audio issues as far as dropouts or jittery sound when they came out of the setup menu? (not all the time)

Also is anybody having any video issues when coming out of the setup menu?
If I set the 972 to anything but bypass when watching my bluray player and I come out of the menu the picture is mostly purple. I have tried my player on every resolution including auto and it always distorts unless I use bypass which is fine.

nice unit.....don't know if I can live with the audio delay switching channels on my motorola cable box. I'm a constant flipper

definately more refined (warmer?) then my Anthem MRX300.

Bill...I have not played with the video much, but it seems that I do not have any issues with the video set to bypass or auto.

I don't have video issues in bypass, in auto/1080p it's fine sometimes and sometimes it freaks out when coming out of setup.When changing channels or advertisements and it switches from DD to stereo I get delay.All HDMI connections, I may try optical for cable and see.

All the units I have had that sound really good have some quirks so I'm used to it, for others I can see a problem.

I tried the optical cable...same delay. This delay really sucks.
I also tried the L/R analog cables out of the cable box. I lose a little lfe as to be expected but I have to say dolby movie is exceptional and you don't have any delay switching channels.

I had many avr's and a pre-pro, a couple quirks i'm used to. But I don't think I can live with these.

How long of a delay are you getting when switching codecs? I'm getting around 3 seconds or so. It has not been much of a problem, but am also not much of a channel flipper.

I think you:

change the mode on the remote
press 2 buttons on the RECEIVER to scan
press enter on the remote to accept

Turn off auto surround in the input setting - its basically switching from down mix to digital over and over with each channel change i bet

I can simulate this by pausing a bluray with auto surround on - it flips back and forth between multi PCM and downmix

It takes more time, but it can be done.

When you go into the Auto Setup screen, you have a choice of which position to save your upcoming measurement as:



Select Position 1, start calibration (measurements), if you're happy with the results, run computation, finish by saving the settings, the receiver will power off.

Update the receiver to the +3dB curve, select Position 2, start calibration, run computation, finish.

Update the receiver to the +6dB curve, select Position 3, start calibration, run computation, finish.

Apparently it saves measurements/results/computations for three independent positions, because...

When configuring each input, you get to specify which measurement position to use for that input:



Manoj (adude) has his 972 set up this way. So it works.

But aren't you supposed to reset the unit after loading the sub boost file which will essentially erase all calibration settings. Jin from tech support also informed that boost files boost low end for all channels below 200hz.

So it seems like the reset is not needed after loading the files?

I will try it tonight.

It would be great to know if it does boost all channels below 200hz as that would have a huge impact like a few reviews I read.To answer cschang 3 seconds is about right, and I'm also not a big channel flipper but it is kinda noticeable.I think I already tried turning off auto surr to fix but I'll check it again.

I just talked to Manoj(adude) and it seems like the reset after loading the new curves is not needed.

I'll be doing Sanjay's suggestion tonight.

Also try using the Natural curve. I helped Ken (RUR) set up a 972 at a friend's place recently and thought the Flat curve sounded a bit thin. Natural sounded a little closer to perceptually flat, though I still think the bass needed more boost to get there.

Will do.

I am wondering if these target curves deal with 200hz and below, or just the bass channel.

There is a lot to try. I paced myself so I have time in between to just enjoy the weekend.

Curtis, on Wednesday Sanjay and I are planning to add the +3/+6dB curves to the system we set up last week. We'll do before and after measurements and post them so that all can see exactly what they do to FR in one man's system.

Ken

That would be great, thanks in advance.

Ditto.

I am thinking about having Sanjay and some of the members of our local LAAVA (LA A/V Association) group come out to check out the system (5.1 in a small living room) in a couple of weeks, and grab some lunch at the local all-you-can-eat Mongolian BBQ...you are more than welcome to join...anyone for that matter.

Maybe I will have my MX-700 re-programmed by then.

The labels for the 3 subwoofer curves were for convenience, only, and do not necessarily indicate which is correct. As Curt has pointed out in the other active R-972 thread, only the target curve for the subwoofer is changed. The unit should not (and must not) be re-set after updating the target curve with the subwoofer level files. Dr. David Rich, then technical editor for the Sensible Sound reported two things that are pertinent for this advanced crowd: 1. He insisted that the curve labeled +6 is actually flat--or at least was in his room. 2. He also suggested that after the data acquisition and filter construction was saved to the AVR, reversing the phase of the subwoofer(s) gave better integration between the main speakers and the sub. While I have not made any effort to compare the in-phase/out-of-phase sound, I do reverse the woofer phase as the final step in the R-972 audio calibration.

Anyone have a toll free number to contact Sherwood tech support? I am having some hdmi issues (blackouts) and want to see if there is a easy resolution. I love the audio of this receiver, and don't want the hassle of returning it.

Well, I just put in an order, so I hope I get a good one

It will be driving a Outlaw 7700 to a 7.2 set-up that includes some Bipole/Dipoles on the sides. Hopefully I won't have any issues. I am also wondering whether I should continue to use the Velodyne SMS-1 that currently runs the 2 subs.
Thoughts?

Originally planned on an Outlaw 998, but that went with the Dodo...

Try it with and without.

I had been using an Antimode 8033 with my sub, and don't feel like I will need it any more.

Regarding the +3 and +6 dB targets for the sub, is this a problem with sub calibration? Or is it just people like a fuller sound?

Also, does the same issue arise for 2 channel? In this case, there doesn't seem to be any way to boost the bass. I am primarily interested in using this for stereo/multichannel sound without a sub due to its room correction capability, so this is important to me.

I recently bought the 972 and love Trinnov. I am less impressed with the quirks of the receiver and have a few nagging issues.

I would greatly appreciate feedback from other recent and long time owners could tell me if these are "common" issues with the R-972...


1)The video upscaling light and indicator seem to be the opposite of what one would expect. When I select "bypass" both the red indicator light and "V.UPSCALE" indicators come on. These indicators then turn off when I select either "Auto" or any video mode other than bypass.

2) Whenever I enter or exit the setup screen I get green artifacts on my TV.

3) Occasional video tearing or complete video dropouts in any video scaling mode. (Though as above indicator lights suggest scaling is off)

4) Occasionally, usually during either post setup screen or after input change, the receiver will mysteriously go silent. This state is resolved by placing the receiver in standby mode then back on to get the audio back.


Despite the issues above I love the sound of this receiver. I would appreciate hearing if anyone else (or most folks) experience the issues above.
Thanks
