Sherwood R-972 User Thread - Page 76

Hey guys, anyone who has purchased from A4L, new with 3 year warranty, did you register with the included card or on-line? The card doesn't even have a place for e-mail address, how do they confirm registration? Someone?

I've shared it plenty of times in the Audyssey thread, directly with you:

Hello,
My R-972 is arriving Tuesday. I have read the threads, user notes, and manual. I am posting now to clarify a setup question. Currently I am running an Onkyo 707 with all 11 speaker positions used. I then select seven for playback, PL IIz, PL IIx, or DSX wide/heights. My plan is to connect the Surround Back/Multi to a speaker selector that is connected to the SB, FH, and FW speakers. Then run Trinnov and save each setup to one of the three Positions. I am getting my self prepared for the numerous trials and resets but I think the end results will be pretty awesome. Any thoughts?

The beauty in trinnov is in more how it gives an overall 3D effect in the sound, and re-positions the center channel. Not running it through the mains and side surrounds might ruin that, but using the matrixed data from the 707 may give a great result.

I'd say try as many different combos you can until you find the best one you enjoy.

I was fooling around with my R-972 a few evenings ago and have got something messed up. I apparently can no longer get high resolution audio from Blu-ray discs from the HDMI input. The only audio choices I seem to have (by the left control knob) are Dolby Digital + PLxII, though I can choose between music, movie and game versions of that. Before I messed something up, the 972 would usually say DTS Master HD + PLxII when playing Blu-rays. I tried changing the Blu-ray input on the 972 from HDMI audio to Auto, but no fix. I also changed my Blu-ray player outputs to PCM from Auto but it made no difference. The Blu-ray player says it is outputting DTS Master HD at a fairly high bitrate.

I can anyone think of what I accidentally messed up and how to fix it? I could do a full reset, but then would have to re-run Trinnov.

Thanks.

Make sure HD Audio is on, it is on page 2 of the Video 1-5 page.

It's going to go to the fronts, center, and surrounds. I'm just going to use the selector to select which speakers get sound buy utilizing Trinnov with the SB, FH, and FW and saving it to one of the positions, as eluded to in the notes.

Well finally got around to playing with it for awhile. Trinnov 2d and 3d all make voices seem to come from the right speaker. Don't know why, but I am no liking the effect. Going to rerun all three positions tomorrow and see if anything changes..

 

Be sure to do a factory reset beforehand.

What was the azimuth reading for the center speaker? Should be 0 deg, +- 2 deg max.

ugh... on spot 1 my center is reading 16 degrees H and 84 degrees V
on spot 2 my center is reading 21 degrees H and 88 degrees V


I already did the 6db boost file so I think I will I am going down now to reset everything and do two more runs...

It looks like the mic is 90 degrees to one side. Is the red dot pointing at the center speaker?

Yup, there's your problem. Unfortunately, it can be a bit of trial and error. As bguzman has said, point the red dot at the center, take measurements, twiddle the dot aim and repeat as necessary until you get a result somewhere between -2 and +2.

Ok Jedi Masters: Here are my next three after a reset.

My head is about to explode! Used a tripod And yes, I do have the red dot facing the front dead on where my head should be.

Speakers are all MB Quart In walls. The center channel speaker is somewhat below the projector screen and about 2 feet below the main R and L. All surrounds are on the high side about 3 feet above the Front L and Front R speakers. Sub is an epik Legend, hooked up via crossover bypass volume middle. All speakers took after three bursts and reported no errors.

"twiddle the dot"?? What is that, some kind of new approach to measuring? :-)

I've found changing the dot aiming point with any granularity to be quite challenging. Diddling with it won't do, one must twiddle.

The first position looks to be within parameters. You do realize that Trinnov is not like Audyssey where there are multiple mic positions for a calibration?

Yes, I know the difference, but if I want to use different modes for different inputs I need to have 3 calibrations run, correct? There is no way to copy calibration 1 to calibration 2.
I plan to run different setting deepening on material. I also thought the subwoofer was not supposed to have a measurement other than distance..
For you microphone twiddlers, do you have the mic sitting flat or tilted. In my case the center channel is lower, should I tilt the red dot to point directly at it? I thought the purpose of the red dot was to aim it directly at h center of he screen...

I think it would be better to save the different modes in to the Video assign setting, Video 1-5. Yes your first sub calibration is what it should look like.

The mic should point perfectly upwards. If it's angled left, right, front or back you'll never have any luck. Even if the red dot is pointed perfectly towards the center. I could get the center at 0 but it would report my Fronts (and other speakers) as being different when they are actually aligned perfectly... until I got the mic squared away I just keep going back and forth moving the mic to no avail.

 

For those who love the 3D remappung I tried a little trick here with good results. Not quite Trinnov but helpful none the less. :)

With all the returns and warranty exchanges talked about earlier in this forum, I suppose I'll just send in the warranty card, keep my receipt close and hope for the best. Would have been nice to hear from fellow A4L buyers. Thanks, Doug G.

Learned that if you do a factory reset after doing the "6db bass boost file" you have effectively removed it! Apparently you are NOT supposed to do a reset after installing the hex files?
This thing is giving me a headache...

I believe we were all warned of just such occurrences.

To keep from going crazy trying to get the center to be 0 deg, secure a laser pointer to the mic and note where it hits the wall on the 1st measurement.

Then use trigonometry to calculate how much right or left you need to make the spot move to get it close to 0;repeat as necessary.

Note that it's also possible that the mic is not on a line throught the center speaker that is perpendicular to the front wall, i.e. it may be offset.

Hmmmmm, I like that... Going to dig out the laser tomorrow.
since I have a '"good" calibration on the first position, I am ASSuming I can just rerun #2 and #3 and that will replace my " wonky ones"

Comicguy,

How many sources are you hooking up? I ask because if you only have one listening position that is all the calibration you need. Have you read this thread?
Edited by bguzman - 2/24/13 at 8:52pm

Yes, I only have one listening position, but I am freaky about wanting the BEST calibration I can get, hence my statement about redoing #2 and #3. And yes, I have read that thread as well as the one on HTS...

I can respect that, I guess you are in it for the long haul if you endured all that reading. I found it exhilarating. I wish you all the best. My R-972 shows up Tuesday, that's when my fun begins. My plan is to calibrate three different speaker configurations. I'll be in a rubber room by Friday.

Ironically,someone earlier in this thread "claimed" that doing a reset after loading the Hex file would effectively make it load properly.As you have just found out that actually deletes it.

Indeed. 3 DIFFERENT speaker configurations? You will make it to the rubber room with me wayyyyy before Friday. :-)\

As far a reset clearing the bass file, I was going by the testimony of someone who actually measured the output with their SMS.
