No I can't as I gave the receiver away and with it was the manual which discussed how to enter the information which, IIRC, was basically was nothing more then a delay to balance time domain issues; speaker position with added cable length. I figure Audyssey automatically adjusts as there would be an expected time delay due to longer speaker wires plus differences in listening position distances.

Do you recall the receiver's model number?

Manuals for most older receivers are available somewhere on the Web.

Changing the delay to a given speaker by a few milliseconds has audible consequences. Changing it by a few nanoseconds doesn't and I find it hard to believe any receiver or prepro Marantz has ever made offered such control. Perhaps there was a misprint in the manual, etc.smile.gif

Perhaps the compensation was for the conduction losses incurred in the longer wire? The blood pulsing in your head would move it enough to swamp out any delay compensation on the nanosecond time scale.

With all due respect, now you're saying I imagined I did what I say I did. At times, we're all delusional but in this case, I wasn't deluding myself. But philosophically, can one ever know when they are or are not being delusional?

I sure wish I could recall the model number as yes, I went to the possibility of downloading the old manual but nope, both the receiver and the model number is gone and other than it being a SR6xxx series purchased about ten years ago, I've got nothing.

I'll go so far as to say it's possible that I read somewhere the user was suppose to include wire included delay into the distance setting as it was too long ago to argue in certainty.

Audyssey's FAQ section won't tell you this.

Unless your speakers are at least several hundred miles from your AVR, any delay introduced by speaker wire distance is completely inconsequential and does not impact in room audio in any meaningful way.

Please stop guessing and confusing people who are trying to learn how these tools work. When you have to lead your post with: "Right or wrong on my part, I'm under impression that Audyssey automatically takes into consideration, the length of speaker wires as opposed to simply taking a tape measure of the distance from the front of the speakers."

It should be an indication you need to read more and post less.

This is true. It's just physics after all. The speed of electrons in a cable is much much faster than the speed of sound through air. Any cable length differences are negligible.

My understanding, regarding copper wire, yes, electrons do move faster than the speed of sound; about 1/3 of "c" or ~100M m/s.

Actually, I just learned something new about something I thought I already knew. biggrin.gif It's not the speed of electrons in copper which matters. It's the propagation of the EM wavefront, which is actually much faster:

http://en.wikipedia.org/wiki/Speed_of_electricity
Quote:
Propagation speed is affected by insulation, such that in an unshielded copper conductor range 95 to 97% that of the speed of light, while in a typical coaxial cable it is about 66% of the speed of light.[1]

Speed of light: 299,792,458 metres per second
Speed of sound: 343.2 metres per second

Or ... the speed of light is ... substantially faster than the speed of sound. So we are left with the fact that any differences in cable length anywhere in your system are indeed negligible.

Wishing you well as I love how some choose to act as if this wasn't known information at the time I posted what I posted.

So are you admitting you were obviously wrong then, BeeMan458?

Wishing you well as there was nothing wrong about my comment as it's obvious some here are out to pick a fight (trolling) and they're not going get one.

I have a AV7005/Emotiva XPA-5 combination.

I just acquired a SVS PC13-Ultra sub and set up using an existing SVS AS-EQ1 sub equalizer.

I set up the SVS AS-EQ1 and then ran Audyssey on the AV7005.

Audyssey on the AV7005 reported (via check Audyssey parms option) a sub distance of 23.6 ft.

However, when I was in manual setup (to reset fronts to small), I noticed that the sub distance there was set at 20 ft. The distances for all other speakers were exactly as per Audyssey - except the sub!

The following is what Audyssey reported vs. what I see in "manual" setup:

FL - 17.0.ft (same)
FR - 16.8 ft (same)
C - 16.6 ft (same)
SR- 3.6 ft (same)
SL -5.2 ft (same)
Sub - Audyssey reported 23.6 ft/Manual option shows 20 ft.

If I manually up the sub distance to 23.6 ft, the pre/pro accepts this. Coming back into the menu still shows the same value. However, if I power off (i.e. put in standby) the pre/pro, the sub distance resets back to 20ft!

Any idea why this may be happening?

Thanks,

Jester:confused:
post #8565 of 9615
Make sure there are no appliances running, ac refrige, etc. here's a worse explanation my 7005 doesn't send out a test signal for the sub anymore. It worked fine for two months and now nothing. I hate to think I have to send it to a shop and do without my marantz/Sunfire ! Any thoughts on that, hope it's not a manufacturing flaw on the units
post #8566 of 9615
^^
Have you tested the sub itself and the cable? If both work, then first try unplugging the 7005 for a few minutes and if still no sub test tone, then reset the microprocessor.
post #8567 of 9615
Yes cables tested fine will try the unplug maneuver but a little skittish about reset, if it doesnt work I lose my setting and it won't recognize my HSU sub even though I could copy my settings and perhaps reprogram manually
post #8568 of 9615
I have gone thru a couple of resets and have been able to load up my settings after the resets. Just make sure you save your settings prior to the reset. The only time I lost all my settings including my firmware and airplay upgrade and update was when my unit was serviced with a new HDMI board.
post #8569 of 9615
It would appear the replacement 7701 will eventually get Flac192 support. Any chance the 7005 get a firmware update supporting the same?
post #8570 of 9615
AFAIK, no .... only the X006 and X007 models. frown.gif

post #8572 of 9615
Hardly ... a smart phone can be used to stream Spotify to the 7005.
post #8573 of 9615
Yes, you can use an iDevice to stream via AirPlay practically any audio content to the 7005. I would even say that the user experience on the iDevice is better than the same services (ie Pandora, Spotify, Lastfm, etc) implemented in the AVRs I have seen to date.
post #8574 of 9615
But you don't have a GUI on your TV to control things if you use your smartphone, right? [and I guess you are using up minutes of your plan when listening to music , but if you have unlimited minutes this wouldn't matter to some. I don't have such a plan though.]
post #8575 of 9615
Streaming music would be part of the "data" plan and AFAIK, when the phone is connected to the WiFi router it's not using the data plan (ie. it's FREE smile.gif ).

That's right. If your iDevice "sees" and is connected to a WiFi signal in your home, it will not affect your data plan. Even more so, if you plan to use AirPlay, you will need the Marantz and iDevice to be in the same local area network. I do it all the time, it is great. I never use any of the streaming services built in to the 7005. I rather hold my iPad or iPhone, go through the playlist and pick and choose the songs I want to listen. The quality of the audio is OK for background music while doing other stuff. For strictly music listening experience, I load up my FLACs from my NAS.

What iDevice are you referring? Something you download from Appstore for the iphone say? If yes, is it called just that?

Sorry, I should have had specified:
iDevice= iPod Touch, iPhone, iPad or even the newer Macs. Basically any Apple device that has the AirPlay feature present. I call them iDevice just because its simpler.

You and pretty much anyone in the tech industry or among tech lovers...it's a pretty common phrase.
post #8580 of 9615
I just got an AV7005 and ran the setup today. My system was working fine with my Yamaha AVR but with the AV7005 I'm not getting anything from the left surround. I swapped RCA cables for the left & right and the problem followed the cable. I'm suspecting the AV7005 left surround channel is defective. Any other trouble shooting you would recommend?
