Topic: Think My Newer 722 AD Board Still Has Issues...

[mhibbs]

Gotta hand it to the guys at Sound Devices, they managed to engineer a product that takes about 1min to disassemble and a fucking HOUR to put back together.  I've taken apart a lot of shit in my life but never have dealt with anything as frustrating as putting this case back on.  I seriously was beginning to think I was going to have to mail it to them, but I have some things to tape this week so I stuck with it.  To make it worse, I was just double checking the AD board b/c mine was missing the revision sticker even though the build date was supposedly past the line change on the boards.  Sure enough, they just forgot the revision sticker for the back, I really didn't need to take it apart.

To the point though, I'm not sure they've fixed the board issue.  I had some popping in one of my recordings this weekend...which is what prompted me to double check the board revision in the first place.  They're not real violent pops though like you would typically see w/ a DAT deck...softer.  And I have a small section that sounds like paper tearing.  It's a strange sound...not a typical digi-noise kind of error...more analog...and the waveform in that section appears more normal.  Not an angular spike or flat section like you see w/ digi errors.  Anyone else  have anything similar w/ an older board that was known to have issues?

i never had to get a new ad board and mine has not had any issues like that so far.

the only issues i had were firewire connection/transfer problems with my powerbook.  the latest firmware has seemed to rid me of those problems though.

What were you running in front of it? Maybe bad cable? Pre? Power related issue?

[mhibbs]

My Oade m148 which has never been the source of any issues whatsoever.

Replaced my A/D a lilttle while back...  I have a very early serial # and have had ZERO issues with it..

However I do share your frustration in putting the thing back toghether...

Agreed on putting it back together. It really requires two people. Once you get the case aligned and snapped together, someone has to hold it while you screw it shut. I used my full weight on my knee to do this, but I should have just called a neighbor over. It took a freakin half hour or so to do!

i stood on it to snap it back together.  that's when you know something's a tank

I did not stand on it but it was called a few choice words....  over and over again!!

I can go back and find the sections and post pics, but I really don't think you'll get much out of them.  It's a very analog "tearing" sound....not a pop or click.  It really sounds like tearing a piece of paper.  The wave appears normal.  It's not clipping, there is no spiking or squaring off of the waveform, etc.  I've listened to it several more times and I'm now not convinced it wasn't in the PA.  So far, I haven't seen the problem re-surface on any of my recordings.

Have you reformatted the drive? Maybe it was heavily fragmented? I've noticed one or two spots like you mention in some other 722 tapes. Only about a half second or so in length though.

Drive was freshly formatted and there was nothing on it.  Who knows.  So far, it hasn't happened again.
