i was wondering about that...but doesn't the jump create a click regardless of how big the jump is?  and if you need to jump like 3 or 4dbs, 6 or 8 little clicks will probably be a lot more noticable than just 1.

You won't hear a click no matter what if the design is good.  Listen to the V3 when you increase gain by +5db.  There'll be a noticeable jump in levels, but not a "click"

As to the second part of what you're talking about, this is pretty much what the same thing as analog vs digital.  Analog is smooth, digital occurs in jumps.  The more jumps you have, the less you notice it.  So a digitized signal at 44.1k will not sound as good as a digitized signal at 96k.

I'll try it in ascii:

                  ________________
                /
               /
             /        analog increase in gain
           /
         /          y-axis = signal level,  x-axis = time
       /
----


                 ____________
               _|
            _|
          _|         digital increase in gain (0.5db gain steps)
        _|
____|


So both sweeps increase the gain over time (the time it takes for you to turns the knobs), drawing not perfect, but assume each method brings you from one gain level to the same ultimate higher gain level.  The analog sweep will sound smooth to the ear, as it is smooth.  The digital sweep will sound smooth to the ear so long as the incremental gain steps are not that large.  So with 0.5db steps, it will sound smooth as gain is increased.  If the gain steps were 5db, it would not sound smooth, but you would hear definite jumps as it went for example from 0db to +20db.  Gain steps of 1 or so would probably sound pretty smooth, above that noticeable.  Steps of 0.5db would probably not be noticeable by anyone.

nice use of ascii...yeah, that makes sense.  at some level, even variable gain is jumping in short intervals of stepped gain.  hopefully you are right, would love the opportunity to run this with the psp2 outboard.

Right, but the increment in gain is applied at the analog stage.  The a/d simply encodes it.

Yea, understood.  I was just using the analog vs digital realm as an example to understand how it works, but should've been more clear.

It does seem odd to me about the 0.5 increments, especially as it is applied at the analog stage.  If the 722 was just doing digital scaling, the 0.5 increments would make sense, but I'm not getting why it would be designed this way for the analog realm.  Unless they're using a resistor array rather than a variable resistor, but for 0.5db steps, that's a lot of individual resistors.

Exactly.  Doesn't make any sense.  If they are already using variable resistors with the mic in, why would they change it for line in?

Digitally controlled analog gain changes are audible - at least in one such design - in the Metric Halo MIO. It's one of the things I hated most about the unit - most gain changes (even in 0.1dB steps, though I'd usually switch up and down 1 dB at a time) were audible. I tried to set levels on openers all the time and was usually pretty conservative about it.
Out of the game … for now?

The page at Sounddevices is updated again. They have removed the preliminary pricing info (2k for the 2ch version and 4k for the 4ch version). I can only take that as a bad sign.

Also, added the firewire connection information and gave dimensions

Removing the price indication is scary

Perhaps a good thing.
The Fostex FR-2 is now nipping at their heals.
There's  the Marantz PDR-690, as well.

4GB MicroDrives are being seen under $200

Delays can be pricey.

I'm familiar with the Marantz PMD670 but what is the PDR-690 and where can I find info about it.

Thanks

It is PMD, not PDR...I renamed it by misteak.

the video's are laughable.  You know they are going to put a 2.5" lappy HD in the thing.  I am leaning more towards vaporware the more info they release.  

The killer app in this situation is a unit w/ comprible(sp?) specs to what they claim in the ~500 dollar range.  2 grand from what they had posted before is silly.
