So tonight I used the 722 (which has the current firmare) and about 20 minutes into the show, the meters, which were behaving perfectly, started only lighting up the last green LED and would flash the last 2 red leds, with none of the LEDs in between them. Definitely looked like it was clipping. I turned the levels back all the way and the number of green LEDs would get lesser and lesser, but the red ones at the top would still flash uncontrollably. I stopped recording, turned the unit off, turned it back on, same problem. I did the same thing and the next time it worked fined, and there were no visible problems. As soon as I got mine working though, Charles Fox had exactly the same problem with his. He is also running the current firmware. He fixed it by putting the V3 in front of it and running digi in. That being said I dont think the digi in is the problem as my problem was mic in and after a couple of cycles it went away, and also I ran a full show on sunday with no problems. Seems to be a software inconsistency somewhere, the fact that it isnt constant. The other similarity with Charles' and my 722s is we both got these units out of the last shipment.
In listening to it at home, the points where the lights were going haywire, there are pops all over the recording...intermittently out of both channels. Once the unit was rebooted the final time though everything sounds great.
I have posted to the SD users forum, link here:

I will report back with what they come back with

bummer.... :-\
very strange

very strange
I am not too concerned...it failed when there was a backup present, and since it is intermittent, I am guessing it is a FW glitch...if you look at the SD support forum, someone else had a similar issue. Typical of rolling SW updates though...after the first tested load gets changed it takes you several cycles to get back to stability. Definitely not fun to not get a tape, but listening to the most of the show I have, it sounds fantastic...makes up for it a bit, and I have no doubt SD will fix the issue...

oh i'm confident it will be fixed post haste, but i just thought we might have made it to 100% stability for our purposes with this box. 99.9% of the time I'm the only taper so stable recording is an absolute must for me.

undersand that...the odd thing is I ran on Sunday night with zero problems...initially I was thinking maybe the humidity (and it wasnt that humid) was causing the issue, but not I am pretty confident it is a software issue...

Nick thanks for the information on the new units....I really want one of those. :-\

maybe by the time mine gets to me in mid-end june, the glitches will be worked out.
hope so anyhow.

Nick: shoulda used a 744' :-*

helpful as always Davis :P

Listening to it right now Craig. Sounds good. Hope the drive wasn't to rough today.
-
Nice to know - I will be on the lookout.. I rolled Melvin Sparks and The Bridge on SAT and had no issues...
That sounds quite odd and hopefully will be resolved soon. Thanks for the heads up ..

update on this, I just got off the phone with Jon at SD and he has provided the samples I sent him to the design group...hope to have some feedback soon.
-
the old fw seems to be the way to go, glad i have yet to update!

1.37 has been the most stable firmware out there since the 1.15 that came preinstalled on my 722. SD has made it clear that in no way should any of those old firmware builds be in use right now. 1.24 was the most problematic for users, based on comments on their support board.
If anyone has a 722 or 744t in front of them right now, I have a small favor to ask. Could you PM me?
-
actually truth be told, 1.15 was probably the most stable...everyone I know on it has had zero problems. The biggest issue has been that the lock all buttons function wasnt present on that release

OK, follow up on this, Matt's post from the SD board below:
This is very strange. I listened to the mp3 files, and to my ears, sounds like a problem with the A/D converter chip. If it were a problem with the analog circuitry preceding the A/D, the level would change along with the gain pots. I very much doubt that this is a firmware issue. As unlikely as it sounds, it does seem to me that both of these cases are A/D converter problems. Please contact our support guys - Jon or Justin and we can arrange to get the units back to troubleshoot, or we can send you a new A/D board, which is a fairly straightforward replacement.

I just got off the phone with Jon and he is going to send me the AD board immediately...said it is a simple swap. Will report back...

how comforting...
I can't believe that it happened to both you and Fox, at the same show, within minutes of each other... sounds like lightening striking twice...
How many times have you run 1.32? I'm trying to think and I believe that ours has been run for 3 hours of Panic, a couple of hours with Patterson, and for a night of Truckers in Isle of Palms. Have you reformatted?
-
actually running 1.37...only ran my unit once since I got it with no issues. I am guessing that it isnt the firmware or they would be having more problems...the fact that two units failed that came from Cascade's latest alottment leads me to believe it is a component failure. Am I happy about it? No, but when they offered to send me the part, swap it out myself (as I wanted to used it this weekend) and it wouldnt void my warranty...eased my concern a little....
-
I have run a few times with 1.37 and have not seen that issue.
Noone should be running 1.32. It may have workled a few times, but it will eventually fuck you.
-

Im glad I have not seen any issues with mine yet. However, its good to know they have been fast with support issues and firmware releases. Take pictures of the A/D swap if you dont mind.

I had almost talked myself into going on the list. After the latest episode, think I'll wait to see what the sonosax looks like.

fwiw Marc, this incident appears to be isolated...take that for what it is worth

The sonosax may have a preamp more to your liking. I'd base a decision on that but I would not hesitate to get one on account of this issue. The 722 is young product and they are still getting their processes dialed in. You're going to find that in any new product to some degree.

just do it already!
-
alright got the new board, replaced the previous...ran for a 30 minute span with no problems...will give it a run tonight to see if the problem is cured...
-
ran last night with no visible issues. Will take a look/listen to the waveforms tonight...hopefully the new board fixed the issue.
on a seperate note, ran the channels linked last night....cursing myself for not having done it sooner...
-
i've been doing that when stealthing. makes the initial level set soo easy..

just so much easier to deal with when the volume gets louder as the show goes...

I've never ran mine any other way.

I love it, although I had some problems the 2nd night of mule keeping it balanced out. What settings are yall using for metering? I think I have been setting it on peak hold +vu but don't remember. I need to look at that tonight.
-
I'm using peak hold only. It's the option that's most like what I was used to with the ULN-2.
