mind helping the ones who are not regg'd on there and paste what they are saying?

Sound Devices has determined that the analog-to-digital converter circuit board in 722 an 744T units identified below has the potential to intermittently fail. The failure condition manifests as "popping" noise or digital hash when using analog inputs. This is not a problem which gets worse over time, and it happens rather infrequently and does not happen on all units. Typically, a power cycle will clear the condition. The converters are most prone to the failure at 96 kHz sampling rates. The problem can occur at other sampling rates with less frequency. Sound Devices has seen only a handful of failures, but we will exchange ALL suspect A/D boards as a preventative measure.

Affected Units:

722: Serial numbers 470499999999 and lower which do NOT have a "v14", "v15", or "v16" sticker directly below the serial number sticker on the back panel. The "v14", etc. stickers indicate the sub-revision of the unit.
744T: Serial numbers 460499999999 and lower which do NOT have a "v14", "v15", or "v16" sticker directly below the serial number sticker on the back panel.

There are two options to resolve this issue:

1. We can send you a new A/D board and replacement instructions if you are comfortable replacing it. It involves removing the top and bottom cover, snapping the new board on, then replacing the covers.
2. You can send us your unit and we will do the board replacement here at the factory.

Please contact Sound Devices via phone or enter a case directly on our web site at www.sounddevices.com/contact_support.htm . Select "A/D Board Exchange" as the type. Sound Devices will contact you and send a replacement A/D board in the mail at no charge.

The new boards have identical frequency response, gain, etc. as the old ones. The only change is more robust digital communication from the A/D board to the DSP. The new, replacement boards are identical to what is being shipped in brand new units.

Thank you for purchasing Sound Devices products, and for your cooperation with this

thanks

no prob man.

requested mine today.
mine fell in that sector.

quick response time from SD - I posted mine about 1:45 PM PST, and got a call from SD a little over an hour later, replacement will go out tomorrow.

sounds like it's a pretty easy fix though, that's good

yep, sounds sorta like snapping a pci card in from the description on the phone with the support guy.
think ill sell the defective one on ebay
Tim, got the package today BTW, pure gold.

[Tim]

awesome! enjoy...

[Ray76]

I will. I had no idea those mics were so tiny.

luckily though there isnt much in the way of "secular" music that i enjoy here, Europe is a veritable mecca for all things classical music.

its a way of life here.

[scb]

i'm in for this too i guess

[Ray76]

i'm in for this too i guess

I thought mine would be out of the kill  zone being that i just got it last week or so.

[MattD]

Ditto for me. Nick, didn't you do this? If it's as easy as a PCI card thing, I'll do it myself too.

yup, simple as can be...hardest part is to get the case to line up on the nothches so to speak when you put it back to gether...but it basically plugs right into the top of the unit...breeze to do

[Diggin]

looks like I am in it too.
was pretty easy to take it apart so I will try it myself, if not they are only 45 minutes away

slam away if you want, but the early returns seem to be consistent with SD history. Products with issues, but excellent customer service to address them as they come up. The Saturn of HD devices.

i have had no problems.

ill save you some money, just buy the 722 without the a/d and you can use my panel.
