"The Optimizer can raise or lower the sonic location of even a single speaker. With Trinnov and Newcastle you can put the loudspeakers where they fit, use the Optimizer to overcome the shortcomings of speaker placement, speaker response and room interaction and still achieve virtually perfect imaging. An interesting byproduct of Trinnov's accurate 3-dimensional measurements are its ability to auto-correct and auto-assign both speaker phasing and channel assignment.
With Trinnov and Newcastle, even speakers connected out-of-phase and to the wrong channel will be properly recognized, corrected and assigned."

How is this any different than any other EQ?

At first I thought you posted an incorrect link and when I googled Trinnov EQ, found the original EQ unit at $13,000! http://www.cepro.com/best/details/te...correction_eq/

I'm trying to wrap my head around a current unit at the 599 price and understand the application notes pdf in the description section of your link. Very ambitious goal.

My first receiver was a Sherwood 60 watt stereo FM only unit - loved that thing - had it tested at a local HiFi store, and it surpassed all specs.

It corrects room reflections. It is one of, if not the most sophisticated room EQ.

Here is a review of the Newcastle R-972.

So, I finally see how it can pinpoint each speaker in a 3D environment. Look at the setup mic;



I new it would either take at least 3 measurement positions to locate the speakers, but with 4 mics used for 1 measurement, 3D location should be possible.

For $600, this should be flying off the shelves, but without all the current bells and whistles like HDMI 1.4A (support for 3D displays), I guess it just got passed by with the other major marketers.

Oh - just read the calculation time to do the 3D location can take 15-25 minutes! Here's the optimizer results screen;

I definitely don't need a receiver at all right now, but I just might purchase this one as it has me intrigued as to what it may do in my room.

Must... resist... only thing I don't like is I am not seeing anywhere how well it handles subs. The review made it sound a little boomy.

It's only one review. ;) Boominess can be handled at the sub controls after the EQ has been run, should it be a problem in your room.

[madpoet]

You are assuming I have sub controls ;)

[tesseract]

Multiple subs often need no EQ. :)

I really would like to hear the difference sometime. But man I hate losing all the bells and whistles of my 5008 :(

[tesseract]

The bells and whistles on my mains amp are... power button, selector switch and volume attenuator. :angel:

For the subs, the Dayton SA1000 PEQ is not being used, I do use the Bass Boost shelving circuit. This might all change as soon as I get off my duff, fire up REW and see what my room response is. I have all the hardware needed, most everything listed in this thread.

Just read a couple more reviews and it sounds like the Sherwood has some serious flaws in the video processor. The 5008 is 9.2, 1.4a compliant, and even has an iPad app ;)

I've read some stuff about the sherwood that is less than flattering as well, especially with the amp section... but it's the damn trinnov that has me geared up. I don't like to fart around with setup, and things like REW just seem too complicated to even know where to start for my liking. I just use whatever the receiver has built in and an SPL meter sometimes, and that's why the trinnov intrigues me.

Love the setup part. Makes me look forward to the madness I'm about to embark on. :brows:
