Datasat RS20i BETA test and comparison with ADA Rhapsody/Trinnov TEQ-12!!!! - Page 5

Very, very cool.

As many of us have known for years... No EQ/room correction = mush.

Looking for more sub calibration notes, graphs when you get the time.

Thanks for your efforts.

Hi Dan,

I have 2 subs that sit on the front wall. B-Deaps.

Mark Seaton came over and we moved a smaller sub all about the room, recorded a response and every place we could find away from the front wall gave less than optimal results. Not sure if the TEQ can change this . The rear of the room where I wanted a third sub tested out with a big dip in the freq response at 20Hz at the seating position. the front wall area is best in my room.

I may yet add 2 ultra low freq subs behind the screen. My subs have a sweet spot of 32Hz but with heavy EQ, we tamed them and extended useable output to 9 hz.. I'd like something like a TEQ to do such and improve response at various seating positions.

Gotcha.

At some point will you compare TEQ in/zeroed-out Rhapsody to zeroed-out TEQ/ Rhapsody in?

The whole system... Replacing my QSCs.

Thanks, Dan, this is really awesome; I've only dreamed of seeing such a comprehensive comparison test of these RC systems.

+1. Great work!!

Great stuff Dan, you're my hero. Appreciate the comprehensive approach.

Dan where are you at, I'd like to fly or drive down to A/B these set ups (what is the closest airport)? Can you do such a set up (Datasat vs TEQ)?

Great work!

Great. Figure out a day as soon as you can so I (and everyone else) can book a ticket down. That is great time of the year for me. I'll bring a good wine to share for after.

Power buy!!

The recent improvements in audio are amazing. The ADA with TEQ and its ability to calibrate through VNC should be a godsend for many users. The top end SPP for Lexicon and Datasat have some very powerful tools that many users will find invaluable. The whole argument for purity of signal is just not viable anymore. Thanks for all your work Dan

Dan:

With Trinnov, are you using their remapping algorithm or are you just using the room EQ?

Jeff

Dan,

Now your putting ideas into my head !!

BTW ... it seems Austin may be dead for next year.

Cheers,

In Chi. all the time, so if you can fit another in, would love to come by if the timing works.

Is this optimizing to get it to measure how you want despite setting a target curve?

That implies there is really no such thing as an automated RC system, and is especially $obering when you need 3 man-days of skilled setup on top of the kilobuck hardware.

A belated Thanksgiving to everyone with the exception of Dan. He I want to thank personally for taking on what could otherwise not be done.

As some of you know, the very first production TEQs began shipping about a year ago. The implementations of those devices, mostly 12 and 8 channel units (with a smattering of 4 channel ones) have been all over the place and all over the world. From a pair of TEQ-12s running 24 channels to a single 12 channel driving a stereo pair (two really big pair 5-ways , TEQ deployment has been more than just traditional.

I think that Dan has homed in on what this device is all about, maximizing the potential of the loudspeakers' performance based on their position as well as the environment that they sit in. Essentially turning a loud speaker into a finely tuned acoustical engine.

I have been tracking this thread closely and the one thing that has amazed me is the element of time. First there are the late hours Dan put into this. When he wasn't tweaking the room, he was posting here. Dan you are due a good nap this weekend. I hope you can avoid the honey do ranch.

Second, I am really impressed in how quickly Dan got all this dialed in. I thought it would have taken a great deal more time to get the precision he was chasing. Bravo. While some will think that 2-3 days is a great deal of time, the reality is that the TEQ is a new tool and discovering what it is all about takes time. From watching Dan work the room via VNC, once he got past the basics, he was in my opinion, flying through the process - all while still exploring new and more advanced features. From where I stand, I thought this was going to take a lot more time than it actually did and was quite surprised to read his last report.

I also want to thank Curt as I imagine he is following along here too. If you haven't yet had the pleasure to meet Curt, I hope you find the opportunity. He is exceptionally knowledgeable in his craft (all things sound) and it is no surprise to me that he has dedicated himself to bringing the magic that is Trinnov to the marketplace. This is his passion. With all his vast knowledge, he is convinced that the science employed here is the real deal. He has certainly turned me into a believer.

I have had the pleasure of seeing Curt interact with most every type of person: enthusiasts as well as their less than enthusiastic spouse; dealers who really understand room correction and those that wish they could; as well as those where English is a second language. He can truly convey the concepts employed here to anyone - he has the gift of communication.

I can't thank Curt enough for making himself so available to Dan. Anyone who might be interested in Curt's services should know that he provides both off-site support (hourly rates) as well as on-site support if desired. If you are interested in deploying a TEQ, I strongly suggest adding a little to the budget for some Curt Time. You will be happy you did.

And while some of you know that TEQs have in the past been hard to come by, I am happy to report that we have still have TEQs available from the last run (but a few) and I am expecting another run in shortly.

Lastly, I hope Dan is able to schedule his shindig before I head out to the ISE show in Amsterdam, as I would love to join you (if you'll have me). Not for the audio or the company mind you, but simply for the wine

He certain has gone beyond call of duty to conduct this test and write about it as he has.

Seeing this a comparison though, has your company done any analysis of Dirac vs Trinnov at theoretical or practical levels? Or is Dan's work the first time you are getting exposed to it?

I admit that I am not as familiar with Dirac as Dan is. Curt has a much better feel of Dirac too but I don't want to misquote him.

While I suspect that electronic room correction between measurement systems will have similarities (I should hope so), what the TEQ brings to the table includes Trinnov's remapping which is such a large part of the "magic" that is Trinnov.

As a side note to what remapping can do, two years ago at a show, ADA had electronics in two theaters that couldn't have been further apart in layout and design. One room was a small sound room with six standard seats in the middle of a 5.1 array.

The other theater was a large 3 row theater with recliners on risers, a 9.3 system with added height channels and where all surrounds were in the ceiling.

I took the speaker engineer from the company who had the first theater into the second theater for a demo (money seat). When it was over, I asked him what he thought (note that the speakers in that room were manufactured by a competitor). His remarks were most interesting.

Apparently, they had been using the exact same cut that was used in the demo I took him to hear and he thought it was rather funny, but both rooms sounded remarkably similar. It was then that I realized that maybe this is exactly what it is all about after all.

"Listening to the experience as the director and sound engineers intended it to sound." Now where have I heard that before

Dan, I'd be fine with just the three front speakers, plus the complete collection of subs as one, at the sweet spot. On top of that a single front speaker including the subs across multiple seats. Anything more is (for me) a second helping of whipped cream on top of the pumpkin pie.

To be quite honest, I thought this would be just "another" comparison thread. Meaning that bias would eventually come into play. But, Dan, I have to say what you are doing is very pleasing and it is great that you are taking the time to do this.

But, I have a sneaky feeling you just love tweaking the lastest tech!!!
