Topic: 722 Errors????

[mhibbs]

Take a look at the attached images.  What does this look like to you guys?  It sure doesn't look like traditional clipping to me.  I'm running firmwire 1.57 which after looking at their website is way more out of date then I thought.  For some reason I seem to have not received "new firmware" emails past 1.57.  Both images are of the same section...I've got several more errors similar to this at different sections of the files.

looks like overloading and not brickwalling, shouldn't be either w/ your setup,  bad cable maybe?  how are the batteries on the 148/248?

does the symptom reverse itself if you flip flip the channels into the 722?

Looks like the converter was overloaded.

Well, it's clearly doing it on both channels so I don't think flipping the channels is going to solve anything.  Batteries in the 148 (what I ran) are very new...replaced last year....all 8 of them.  You're right though...no way to overload a 148 and it was loud as hell so the 722 wasn"t too wound up either.  The levels also aren't extremely hot (hot sure, but it's more of an instant POP when you hear it)...not a typical clipping sound.  Just got the new firmware...will see if it keeps up.  May set it up in front of my stereo, run it super hot, wiggle shit, and see if I can dupe it.

Look at this...

1.67

    * fixed - bad overload behavior from 1.60 fixed


Wonder if that bad overload behavior was really introduced in 1.6 or if they introduced it as early as 1.57.  Like I said though, the line in gain of the 722 was not anywhere near as high as I've run it in the past since the show was so loud.

update your firmware.  this will go away.

Much thanks... +T.  Oddly enough, I'm not running digital in as you appeared to be w/ the V3, but the appearence of the waveforms is certainly very very similar.

already made the firmware update

[scb]

i'm still on version 1.4x

[bkirby]

1.46 is where I'm at

I'm still at 1.46 and have yet to have a problem!!!

[fozzy]

yea I'm at 1.46 too, no reason to upgrade for me,

[terrapinj]

do they still offer the older versions of the firmware for download? mine will be arriving soon and will likely have new firmware - i've been following a lot of these threads about firmware issues and would like to revert back if possible for the time being.

i've never received an update email, nor, given any sort of forum information by sd.

you have to call and verify with them now, no email affirmations are given...

I think that is called "foldback". It happens when a wavform is sort of over extended. Something was being run really hot here. You can see in mid compression a sample or two jumped completly from positive to negative. The result make a wicked nasty pop from the sudden jump mid compression. You can pencil out those foldback errors. I'm not sure of course if it is a firmware issue or not but from what I can "see" your waveforms are brickwalled. This makes me assume you were running really hot levels. Does this only occur when the waveform is being brickwalled or are there any on quieter passages? If you run your levels lower, underpeak do they still occur?

Yeah, you can download older versions, but the newest version 1.74 is what I am using and not had a single issue with it. You kinda have to be crafty to find the older versions, but this linky should work...

PS..there is no version 1.69 firmware (if you look at that link above) which brings up other "helpful links"....kinda stumbled across this...

[terrapinj]

thank you sir!
