New Onkyo TX-NR5008 & TX-NR3008 - Page 227

I also bump up my surrounds (side and rear) a few dB after running Audyssey; just a preference for a bit more action from them.

placement of the calibration mic can vastly effect the overall calibration.. plz describe how you placed the mic position wise & what you used to support the mic as both are very critical to the results . wrong placement & bad mic support will seriously bork the results . as will the position of the speakers themselves , bad placement & aiming will also bork results .

I used to do that as well, but now use Dynamic EQ instead.

I am thinking of buying a pair of Canton Ergo RC-A speakers which are half-active, i.e. they have LFE inputs as well as normal loudspeaker inputs.
I also use a subwoofer.
Several people have come to the conclusion that these Canton's sound best when wired using the normal inputs as well as the LFE inputs.

What would be the best way to wire these to the Onkyo 3008 with regard to getting the best Audyssey result?

1) Use left sub preout for the subwoofer and right sub preout for both the Canton's (with a Y splitter).

2) Use left sub preout for the left speaker and right sub preout for the right speaker plus the subwoofer (with a Y splitter).

3) Use left sub preout for the left speaker and right sub preout for the right speaker and use the front preouts combined with a inverse Y splitter for the subwoofer (and use the subwoofer's internal lowpass filter).

In all three cases the normal front loudspeakers outputs would we wired to the Canton's as well of course.
BTW the subwoofer is positioned outside of the right front loudspeaker.

Totally agree here. I learnt a lot from experimenting when I had a 3008 and it gave me the knowledge to get a decent (first time) calibration now that I have a 5508. It's very surprising how much difference there can be. Some people suggest that it's a flaw of Audyssey for mic placement to have such a big impact on the end result, but I feel that it's proof that the technology/filters/calibration is far more in-depth and provides far better results (when done properly) than anything else I have tried.

I also use DynEQ (in 3008).

Oh sure - preference is fine of course. What surprised me was that he had to bump them up "massively" and they didn't even register on his SPL meter at first, until he changed the sensitivity setting. That strikes me as odd - possibly due to measuring technique? And AIUI, he didn't increase the levels for 'preference' but simply to bring them to the levels they should have been at in the first place - i.e. 75dB.

I'm getting a ridiculous amount of audio drop outs from my 1007 so now considering the 3008 while I ship off the 1007 for repair. My problem is I don't want to ditch one set of problems to welcome brand new ones. I've read the later build dates on the 3008 forgoe much of the problems mentioned. How could I confirm before purchase that I'm getting a 3008 recently manufactured and how recent is recent enough?

Hello,
I use Martin Logan Vantages and Vistas for Mains and Surrounds that I spent countless hours on Placement. The Vantages are 5 feet from the Back Wall, 5 Feet From the Side Walls, and 9 Feet apart. I also used a Tape Measure to ensure they were precisely the same distance from the Back Wall. The Vistas are placed 4 Feet from the Back Wall and 9 Feet apart as well. My Martin Logan Dealer came out and was suitable impressed that they did not move any of the Speakers.

I placed the Audyssey Microphone on a Tripod moving the Couch so the Tripod would be at the precise position. I did this for all parts of my Sectional Couch.

This is incorrect technique; one should measure with everything in the place it will be in during listening. It's best to use a mic stand with boom arm to properly place the mic over seats.

Before I went with the mic stand/boom I used a less recommended but frequently effective technique to put the mic in exact place for MLP: place a shortened leg of the tripod right on the seat. Just be sure the tripod leg is isolated from the seat so it doesn't pick up vibrations, common with taut leather seats for ex.

I used to use a tripod too but find that the boom mic stand makes life so much easier, and halves the time it takes to do the measurements too. I agree entirely about the OP's technique, which may cause all manner of issues. He can pick up a boom stand and mic adapter very cheaply on Amazon. I use this:

And this:

Well worth the few dollars investment IMO.

Keith, does the mic adaptor fit the threaded insert on the bottom of the audyssey mic without issues?

Hello,
I do not see how it could be the wrong technique when I adjusted the Tripod to where it measured at Ear Level when sitting on the Couch. In the past, I simply placed the Microphone at Ear Level on the Couch.

Using a Boom definitely makes sense, but placing the Microphone at the precise level and area with a Tripod seems to be a fairly sound way of doing it. The results were quite satisfactory, but I might revisit it with a Boom.
AD

It does, I have that same adapter and stand.

The low profile stand is better because it would be easier to position without the arm being in the line of any speakers.

Thanks and for measuring does the mic have to be upright once attached to the adaptor? I'm gonna try the mic stand/adaptor route, maybe I'll get better results than my currrent method of just placing the mic on top of the chair head rest LOL.

Yes - the one I linked to is the one I use myself. It's not the highest quality piece of gear you will ever buy but it does the job. A boom stand and an adapter like that makes the job so much easier, you'll wonder why you ever tried without it. It also makes it far easier to replicate a set of mic positions if you ever need to re-run Audyssey and want to achieve the same results as the last time. This assumes, of course, you keep some sort of note of the mic/stand positions when you run the calibration.

It's the moving of the furniture that is the wrong technique. The recommendation is to measure the room exactly as the room will be used. Measuring and then putting the furniture back can introduce anomalies.

Keith

The mic should point vertically - towards the ceiling. The tip at ear height. Please come back and let us know if you hear or measure any differences when you use the mic stand method.

Kind Regards,

Keith

Thanks for the response Omega and Keith. Keith I'll order today. Any idea where to get a 3008 issue free?

Lmao!

I think the vast majority of 3008's have been issue-free; they've sold tons of these things. Mine came from newegg, and has had no issues whatsoever (or else I'm too dense to notice them if they're there).

DITTO. I got my 3008 from Newegg in March, and so far, no issues. I'm crossing my fingers on the heat problem.

I use a PC fan on top. Not sure I really need it, but I had it from use with the earlier Onk 805, which I think ran much hotter than the 3008.

Hello,
The awesome thing to see after a year are next to no HDMI Board Failures.
This was something that had already manifested itself well within a year on the 3007 and 5007.

As for the "Failure Thread", it really seems like 708's are most affected followed closely behind the 808. While some 3008 and 5008's have had the problem, it is not a huge number.
Cheers,

Ok that's encouraging. I called Newegg today to see if they could verify a manufacturing date before ordering, but no can do. Guess I'll wait til the weekend and maybe pull the trigger.

It's almost certain it will be a later manuf date. These things have been hard for dealers to keep in stock. More so for the the 5008 than the 3008, but true for both.

I figured out in order to stop the annoying relay clicks I have to set my Dish sat box to pcm only. This eliminates all clicks but doesn't allow tv viewing in dolby digital only PLII. If I select pcm/dd in the sat box then I get dd but also get the clicking.

Anyone come up with a solution to stop the clicking? I've tried the suggestion of using "last valid" but it didn't work.


Dan

Did new egg tell you when the 5008's will be back in stock? When are they going to clearance them out or run a gift card sale with them like they have with the yamaha a1000 a2000 and a3000 .. Waiting patiently..

Block the sound clicks by putting the unit inside a tv stand cabinet and adding some fans to keep it cool. That's what I did
