The Audyssey Pro Installer Kit Thread (FAQ in post #1) - Page 45

Hey guys,
Just got my own Pro kit, and I have a simple question:
Is the mike holder supposed to be so, well, loosely attached to the boom arm? I screwed in the boom holder as per the diagram on Page 7 of the Pro guide and attached the mike through the hole on the holder, and it seems that if I lower the boom too much, the mike holder keeps coming off. The holder will stay in place, but only if I don't angle the boom too much. That's a bit of a problem, since I'm trying to measure by having either the tripod behind our sofa in a very tight position to avoid moving the MLP, or have the tripod nudged behind one corner of the sofa and my one of my subwoofers.

Other than adhesive, any ideas about how to keep the boom more stable so I can keep the mike holder stable, and the mike pointed straight up?

Thanks,
Stuart

I'm having difficulty picturing what is going on here. The mic holder screws onto the end of the boom, and the set screw tightens it down. So that shouldn't be the problem. Then you stick the mic into the holder, which is a rubber ring. The mic is slender at the top, and thicker at the bottom. You need to push the mic far enough into the holder so the holder is gripping the thick part of the mic. It take a bit of effort to slide it all the way in. Once the mic is in place, the holder should have a firm grip on it, and there should be no chance if it falling out.

Now, where is the issue?

Edit: take a picture if necessary.

Will do if needed....but you may have helped answer my question with that answer about the set screw. I'll find out later tonight once I get the living room to myself again. The issue was with the holder and the boom. Probably a stupid newbie thing....

Here are some pictures. Pics 1 and 2 show the mic properly inserted in the holder. Pic 3 shows the set screw which locks the mic holder in place.

Problem solved; I'd had the mic holder configured with the set screw the wrong way, which made the mic unstable. I thought it seemed strange...the picture set me straight, so thanks, AJ.

Edit: I'd read the 60-odd pages of this thread over the weekend and leafed through the manual, so combined with AS-EQ1 experience and running XT32 a few times this week, I was able to get a basic six position run done tonight. Not enough that I completely believe the certificate (yeah, right, 110 Hz crossover as the first choice on a CS 8080 center with the sub volume at 12 o'clock), but what I got for the fronts (40, 80, 60 for Mythos ST at 12 o'clock; I took 80) and surrounds (90 for Gem XLs) isn't too far from what XT32 gave me, and the trim and distances for speakers and my two Hsu subs were pretty close. Plenty of time to run many more positions and see what I come up with, and refine. But so far, I'm impressed with what Pro gave me: much punchier percussion and match of the surrounds on some MC music (Talking Heads Remain in Light) I tried - even an live concert MP3 didn't sound too bad with PLII Music.

Hi,

So my feedback after my previous problem with Pro 3.5 (details posted above), as today I've reinstalled everything:

1- Prolific latest 1.5 driver
2- Pro 3.5 (latest version with Onkyos)

and after another "time out -2 way communication" problem... solved by switching off/on the 4311, everything went smooth, as previously.

... and yes, happy again!!!

That's great to hear Hugo! Glad it went well.

Would the pro Mic be any good for taking REW measurements?

If you had a calibration file for it it would.

That's the tricky bit I believe.

Hugo, just curious. When I get this error, I can resolve it by simply disconnecting and re-connecting the USB cable and proceeding with the calibration. Did you try this?

When I first asked about differences between 3.4 and 3.5 I was told it was only for new devices. Then when I sent in a file that gave different cross over order between 3.4and 3.5 I was told that the reasons were improvements in 3.5 that led to the xovers difference. When I asked what the improvements were, I just got am email that this was proprietary but the changes were mainly new devices.

So there you are.

Yes, there isn't one. You could send it out to be measured and a file generated, but it would cost pretty much what a decent calibrated mic would cost.

Hi Jerry,


Pfff actually I was a bit when I got the message... so I can't be totaly affirmative on what I did precisely, but if I had to say something, I'd say that I haven't tried that.

Anyway everything is working fine now, so...

Onkyo 5509 firmware out for pro
Hopefully 80.3 is close behind

Further explanation on this is that Audyssey makes occasional tweaks to meet the (sometimes conflictiing) requirements on how to characterize the roll off from different manufacturers when communicating its "findings" to the receiver/processor. The differences in the results are so minor that it's neither worth reloading a calibration nor even upgrading to 3.5 if there is no new equipment in the system.

I'm not upgrading my software.

In my case standard xt32 put the xover at 40hz for my mains. 3.4 pro suggested 80hz then 40 hz. 3.5 pro suggested 80hz with 40hz the last choice in the menu after70, ..

Since I have Montis mains which have is a hybrid with it 10" woofer optimized to match the electrostatsic panel, I am not sure which to choose. In addition the Martin Logan Montis has its own internal amp to power it's sub below 340hz, so there is no clear "power" advantage to the 80 hz the Montis is spec'd to 29 hz as confirmed by the pro before and after curves.I do have an issue at 50 hz due to my room which is corrected in both speakers by the Audyssey software.

So far I have been listening to 70 hz and will then change to 40 hz for listening . Classical guitar and jazz bass are my evaluation tools stereo and SACDs.

80 hz seemed to have some "hang". My subs are quite good JL 112's.

Thus I was looking for a clear explanation of the criteria by which selections are made in xt 32, 3.4 pro and 3.5 pro.

I use a 80.2 with the latest firmware update.

Have you done any waterfall measurements at the different crossover settings to see if what you hear can be measured?

This is good advice. I was hoping that the comments from Audyssey would shed some light. They do have my measurement file.

I do not have the hardware. I am considering omnimic but have been rather busy with my professional life. I have not tried turning off the xover for the Montis but I guess that is also another thing to try.

Maybe you can get some other ears in to listen to what you are hearing?

Sure I will try. The Martin Logan Logan forum suggests no sub for the Montis; I.e. setting the mains to full. This is against the wisdom on this forum.

Problem with having a guest to listen to different xovers is that it takes a while to change between them if pro is setting the filters of each try.

actually the update is available via Net option-
just not showing on Integra site

Yes, the update adds the Onkyo PR-SC5509, Integra DTR-80.3, DTR 70.3 and DHC-80.3.

There is also Pro support for the TX-NR3009 and TX-NR5009, but not the US model.

The firmwae updated without a hitch on my 80.3
just need Audyssey to make a licence available to purchase

Yes, they obviously forgot about that. I was hoping to run the calibration this afternoon.

Changing the xover form 80 to full in my mains led to the center 1st choice xover being full and much different choices than before after that;not optimal. So I will test 60 hz now.70 sounded pretty good so may go back to that depending. 40hz is the last choice.

Clearly the center and mains are linked in some way, I really want 40 hz for the Montis but there is something about 40 that pro does not like. normal xt32 lists it as first choice.

this is a Martin Logan Montis, Stage pro calibration with NHT dipole surrounds and Celestion SL6 rears.

Perhaps I should do a 20 point cal and try again.

Thanks. 80 hz is fine for home theater but I listen to a lot of classical stereo. I amtrying to get the lowest acceptable xover for stereo and then I will bring it to 80 while using the home theater.

I think the dipoles are affecting the perceived best splice in Pro.

I am not sure what AVR you have, but with the Denon 4311 there is a custom setting for Stereo that allows you to have a different seup for 2 channel with different xovers, etc.

I have the integra 80.2.,the Denon feature would work fine for me. I think the attempt by audyssey to match the phase for the front three speakers is confounding my attempts to lower the xover for the mains. This is great in 7.2 system. But for my 2.2 stereo does not lead to optimal results I think . I do both and that has led to my conundrum.

I will work it out one way or another.
