BTW...I have a 80 GB, 5200 RPM HDD in my 722.

Would'nt the bigger HDD give you shorter run times?

no.  If the drive was slower like a 4200rpm drive you would get better run times, a 7200rpm drive would get less.  SD states that the slower drives are adequate for recording.
 

FYI:

I had a 4200 rpm, 60 GB HDD in my 722, which had a bunch of recordings on it, and I got slow drive indication, and the 722 stopped recording.

really? was it too hot?

is it relative easy to put a new HD in? i hear the top of the case is a bitch to put back on :(

what comes stock? a 4200RPM drive?

Capacity doesn't affect power consumption.  Spindle speed is usually impacts power but it's only relative as a general rule.  You may find one manufacture drive is higher RPM but lower power than another manufactures lower RPM drive.

I have an 80G 5200 RPM drive and I get about 5.5 hours from a 6000mAH battery labeled Power2000 from batteryspace.  That is with the meters on low, LCD back lit, phantom to KM140s and a solid signal present at the mics.   Since I've been running line in to the 722, with all other things the same I get over 7hrs record/playback time time but haven't run it down yet.

so does everyone run mic in or line in ???

does  a pad have to be engaged for mic-in ???

I always run the line in because I put the V3 in front.  I think the physical switch is there because it also selects the input impedence.  If it was just gain range they do it with a menu selection and save the price of the switches.

I'm not sure about any PAD for the mic-in.  I think the 722 will handle a wide signal range.

So Bean did you get your V2 wired up yet?

I run Mic IN but for some super loud shit(on stage hons & drums) I have run line-in w/ phantom.  There is a slider switch above the XLR inputs for line/mic and inside the settings there are high/low gain settings for mic input

so high or low gain for mic in ???

still need to buy/find one, prolly cant afford it for a month or two tho :'( so the 722 pre/ad is gonna have to do :) i have alot of painting side-jobs lined up so i should be able to afford the v2 pretty soon :)

still need to sell the v3 too :(

I don't know.  I depends on your mics and the music. 

With 140s and 4023s, I always used the lower range when running mic in.  I never needed more than what the lower range provided.  But I run up close.

With line in, you get -6db to +18db trim (or somethng like that).  I usually run the V3 at 25db to 30db and the 722 is within 4db of 0.

Until you can swap preamps, just run the V3 in front.  It's sweet.  You should run both and get a sense of how they differ, but I think you'll like the grace preamp better.

I run low gain setting with the 4V's. That should give you plenty of room to work with.
I don't know just where I'm going
But I'm gonna try for the kingdom, if I can

What is a V3, why is it necessary with a 722? The mic preamps, and A to D convertors in the 722 are supposedly top notch.

When I got my 722, they were selling raw units w/o HDD, batt., or AC adaptor, which is what I bought. The first drive I put in it was a 60 GB, 4200 rpm. It did not get too hot. I was getting the slow indication, and stopping recording problems when I had approx. 6 hours recording time left @ 24/96. I spoke with Justin at SD, and decided to put the same make, and speed drive (Samsung Spinpoint M MP0804H 80GB ATA-6 5400RPM) as SD sends out with new 722s, except I got the 80 GB, as they supply a 60 GB. I have recorded with the 722 in the Camrade/SD  bag made for the 722, outdoors, with temps around 100 degrees, and have never had any heat related issues.

Installing the HDD is easy. 7 screws, and the bottom lifts off. Be careful with the ribbon cable and connector. When replacing the bottom cover, make sure the tabs on the front and sides fit into the notches on the cover. Be careful not to over tighten and strip the cover screws, and you're good to go. There is also a rechargable NiMH AA cell for the clock and date memory, in a battery clip on the inside of the bottom cover which is easily replacable if need be.

The preamps and AD are indeed really good, those people with V3 simply are addicted to the distortion it introduces. They are so used to that distorted sound that they think everything else is bad. Most of them believe that you have to set the levels so they get into the red. Instead when using the 722 set the levels so that the yellow Led-s flicker and you never get Red. Then post-process the files in your PC increasing the volume. At the same time add compression or whatever you want to have, the clean signal gives you a lot of options.

Personally I like it clean as I record only acoustical music, symphony orchestras , choirs and that kind of stuff.

I think most of the people using V3-s has not really tested going direct in to the 722, they are too prejudiced. And by the way, they are all recording shows going through crappy PA speakers anyway. (Did I get people upset enough -- could you show some A/B comparison files? ) !!

A V3 is a preamp and ADC.  Some people prefer its preamps to the 722, and some prefer its ADC to the 722.  (Obviously not Gunnar.)  Others prefer the V3 pre but the 722 ADC, and still others the 722 pre and ADC.  Good thing we have lots of gear to choose from so we may each choose gear that pleases our own ears.  :)

i got about 6.5 hrs on my 722 running mic-in, low gain, phantom on, BUT i didnt have the backlight on most of the time, im running the test again now w/ backlight on to see :) and levels were set to near-concert levels :)

and FWIW, this is w/ a 6000mah battery

actually, youre right, i havent ran straight mic in to the 722 yet, BUT its because A. i didnt sell my v3 yet, so why not run the per of the grace and the ad of the 722, and B. because i wanted to see what all the hype is about

lemme tell you what, i love the grace pre>722 ad sound tho :)

to be fair i do have to run 722 mic-in sometime soon, prolly for crowes/DBT/RRFB next sunday :)

Sorry, yeasterday was a bad day in many respects. This was reflected in my posts which was perhaps not quite, let us say, balanced.

Anyway, I like the 722 pre and AD enough to recommend anyone to run that directly. It is a bit odd that so many people assume that you really need a V3 to run a 722. There is after all quite a bit of extra hassle in carrying the extra weight and so on.

What I have found is that the 722 sounds really good, as long as I use it the way it is intended. I have the limiter on to avoid hard clipping but stays clear from invocing it. The way to do that is run at a low enough level, blinking yellow lights and never a red light. There is ample room down to the noise floor of the unit and I stay well away from the effects the limiter has on the sound. At home I transferr the files to my program and "master" it. Basically I cut things up into tracks, raises the volume a bit and adds a bit of EQ and compression. This allows much better control on levels than can ever be attained at location.
