recommended Analog-to-Digital convertors?

Al, Until Panasonic releases their Class 10 SDHC cards, I believe the best available are Class 6 which guarantees a 6mb/s (presumably write) rate. Wouldn't that still cause problems for the Sound Devices 702 at 24/192/2?

No, for several reasons:

-- The Sound Devices unit uses Compact Flash cards, not Secure Digital or SDHC cards.

-- I believe you may not be properly distinguishing between bits and Bytes (8 bits per Byte). The slightly under 10 megabits per second figure I mentioned for 24/192/2 is a little under 1.2 megaBytes per second, which is well within the capability of current CF (and SDHC) cards. Lexar Media offers "233x" CF cards (the x denotes times 150 kiloBytes/sec), and "133x" SD and SDHC cards. Those are far faster than necessary. And if your 6mb/s figure is actually megaBytes per second, that would correspond to 48 megabits per second, or 40x based on Lexar's speed rating system.

-- The Sound Devices literature is quite clear that 24/192/2 is supported.

Hope that helps. Best regards,

Thanks Al!

You're welcome!

Upon further checking, SDHC Speed Class 6 is indeed specified as 6 megaBytes per second (=48 megabits per second).

You may be familiar with B&H, if you are involved in video. They carry the Sound Devices 702 at the (excellent) $1875 price I had mentioned.

As well as a great many other digital recorders at lower price points, which you may want to peruse (although of course many of the lower priced units will not support 24/192, and will most likely not be of comparable quality).

Best regards,

Al, this is for my friend, so I'll pass along the info. Thanks again!
