AAAACCCCHHHH!!!!

Last nights recording came out great. I did set one as one project, and set two as another project on the same disc.
We, the sound engineer and tech and myself, listened to the second set last night after the concert. I ejected the disc, (which installs the udfmi file info), packed my bags and came home.

Now I listen to playback, and there is no project 2 listed, and when asked, the machine wants to create another project 2, which has me thinking that the original #2, from last night has mysteriously disappeared. Because the steps to load another project reveal that there is no 2nd project to load.

Any computer heads know what might have happened?
I've poured over the manual in regards to this, and it surely seems that project2 from last night is lost.

help?


When you're done recording a session, does the unit have to "finalize" the disc? It's just a stab, but perhaps you ejected the disc before you closed the session? If you were listening to the project 2 it must have been recorded to the disc, I doubt it's lost, but I'm not sure how you'd go about retrieving it.   :(

If I burn a DVD-r data disc on my pc I can A) finalize the disc or B) leave the session open so that I can add more files later, that's why I'm guessing you're just missing the info that lets the machine know that session #2 is closed.
Maybe a couple of small scratches, but thats because these mics are chick magnets.

Sounds like it may be important to update the UDFMI file by ejecting the disc before listening to it. Or, you may have experienced some kind of power interuption before ejecting the disc. In the event of a power interuption, there is a procedure to update the UDFMI manually by not ejecting the disc.  This could help restore the missing 2nd project. Good luck.

the odd thing is, Matt,... That I did eject the disc when I closed the case on the deck.
 I wonder though,.... If, when I was regathering a 50' pair of cables, and I walked away from the deck while the foh man was listening. I wondder if he turned off the deck somehow? I saw him moving around between tracks,... hmmm?

oh well,... I've moved on, and gotten over that train wreck, and pulled two gooders this weekend. So I'm feeling more confident with this unit out in the field.

I also got the Gator Rack bag for the machine, and its a nice bit of protection! It had total pos screw mount rails that I quickly drilled out and eliminated and replaced with pair of functional mount rails.

2 quick ?s moke may be ordering myself this toy very soon:

The Gator Rack bag rails were crap?  If that's the one, what rail did you use to swap it out?

Have you had to run on a battery yet in the field, or has a/c always been available?

I was considering an Optima Gel cell battery, but I have to crunch some numbers to make sure it'll work...

12 Volt
Cranking Amps at 32F: 625; Cold Cranking Amps at 0F: 500
Reserce Capacity: 70; Capacity (C/20 Rate): 41
SAE Automotive Terminals

The Optima Yellow Top battery is loaded with compact power for small domestics and imports. The Spiralcell Technology means you get twice life of standard batteries. You can store it for long periods and it has incredible resistance to vibration,heat and cold. And the sealed cells allow mounting in almost any position without spilling or damaging your car.

No, I haven't run it on dc yet.
My taping anymore is scheduled well in advance, and its all out in the open. AC power isn't generally a problem, but I am going to rig with the exeltech invertor for convenience.

Gator Rails,....
They are pop riveted in, and cheap bent metal that appears to be hand drilled and tapped. The holes are free form and wandering. And I could not make 4 holes match that units mount holes(4), in any possbile combo. The closest I got was three hole aligned, and one screw that wasn't happy of those three.

So I drilled out the pop rivets, and replaced it with oak 1x2 rails.
I had the piece of oak 1x2 in the garage. And a piece of kneeling foam from Home Depot that i cut into squares of about 2" (free-handed it with a steak knife). I put that soft foam below the legs of the unit, in its proper position on the pads, and drilled pilot holes for wood screws.
Really a piece of cake to fix that little issue.
The price was $65 at Sweetwater, no shipping, and its worth it just for the canvas bag,.... that part of the package is nicely built, as is the box itself. Its just those cheesy rails that are lame.
Overall, a nice box, and a really nice price!

edit, because my fingers are 'tards tonight.

awsome feedback thanks!  :D +t

bookmarked the exeltech inverter, now to do a little more research on battery capacity etc...

m0k3, did you ever get this problem resolved?

My Tascam is on the way...

Now to get the other items to make it mobile...   :P

Nope,... its gone, or at least not retrievable by me. Eventually, when more computer savvy people get these units, there is probably hope for extraction by other means, computer programs, etc.  We were listening to the recording after the concert, so it was burned to the disc. Its likely that no file management info was written to the disc though, so there is no way to read it, so the machine does not recognize any second project.

Its not the greatest loss of all time, and I learned a bunch in the process.


+T for the new toy!!

As far as I've gathered you can prepare a disc to record in 2 manners, either format it so that it's recordable, but the time code is applied on-the-fly, or format the disc including the time code (takes aprox 30 mins?).  I might not be using the correct terminology, or having my facts wrong, but for future reference which "format"/disc preparation process have you used?   I was told that there is no need to "finalize" a disc, so me earlier post has no relevance at all.

I have to figure out the dimensions still but I'm probably going with the Gorilla bag too, I'll tackle the shabby rail system when I get it.  You mentioned using an Exeltech inverter, I'm probably ordering that tomorrow, but they are looking to see if they can get the "rack mount" bracket for it.

I'm still trying to numbers crunch and find out which capacity battery I'll need, I want the smallest (size), but something that's still slightly overkill.

Check this out, with the Exeltech rack plate:



I think there might be enough room to cut out a hole large enough for the V3, all that would be needed then would be to make up a cable for a battery and all the rest would be in the gear bag.  I might need to find someone with a welder.   :)

I am mounting the inverter/power strip to the "inside top" of the 5u rollx rack.  Then I haven't figured out how I'm mounting the big lead yet but the gist of it is, is to use it to insulate the tube pre and the DV-RA from any possible stray RF out of the inverter.  I don't think it'll require a car battery but a 27aH SLA should be overkill.  I'm wondering how long it'll run an a 14aH 12V.....hmmm... I hate math or I'd have already done the calculations.  I'm also waiting on my inverter to arrive so I can see what the heck the connector on the input is....it looks really odd in the pics and I don't know if it includes the mating piece or not....oh the joys of being an early adopter.....

peace, chris

the problem with that rack mount is that,... it'll put your power cable to the front of the unit..
I was considering configuring a mount to screw the exeltech unit into the area above the recorder, with the power connection facing out of the rear of the bag.
Maybe configure a rear set of mount rails, as well as the front set, and mount the invertor backwards, facing the rear of the recorder?
I'll likely do something similar.
You can always screw/bolt and rivet a tray for the V3, rather than weld. You can get aluminum aircraft rivets for pretty cheap, and hammer them down (much better than pop-rivets!).


I can't find the picture now, but it looked as if the other end of the Exeltech was a mirror image of the front (obviously w/out the plug).  I figured I might mount it backwards, use some gnarled headed screws (like the oversized ones used on the back of a pc case) to mount it so that it can be removed easily, either that or feed the power cable back in through a gromet.  The rear mounting sounds like that might be a possibility also.  I wonder if a PC fan would be a good idea or not?  My concern might be inherent noise, I'm sure that can be tested, I have no idea if the unit even gets warm yet.  :P

Good point on the tray, If I'm going through that much trouble I might as well fabricate my own faceplate and have it powder coated.  I'll probably end up doing something similar to that "V3 rack bag" I threw together.  I have some 1/4" aluminum plate, I might end up making my own if the thing costs over $30.

For V3 > DVRA what interconnects are you using?

exeltech xp125 mount

Ahh,... gotcha!

If the battery size works out to be as large as car size,... I'll run the exeltech and battery in a marine battery box on some sort of cart, at least to get it onto location. The recorder and case are heavy enough, thank you very much!
I hate math as well, so,... I'm sort of hoping for one of my heroes to step in with some electrical use 'cipherin for us.

I'll work on a nice coherent HELP! post in the Remote Power section.  I'm thinking the smaller red-top Optima battery might suffice, but if I can get away with smaller and have room to play I'd prefer that. (obviously)

I couldn't find a good formula anywhere online, I'm not done looking.  These Solar/Alternative power sites have a ton of information, hopefully I'll know what the heck they're talking about.

it's something like take the known values dv-ra consumption = 120v at 35watts then figure out how many amps that is.  from those numbers add some pixie dust or something to relate it to 12v and x number of amps compensated for 87% efficency (or something near that).....I'll try and have it figured out by end of day.

ok, I did some quick math:

Part 1:

Watts=Amps x Volts

35w=xAmps x 120 Volts

35w/120 Volts = .292 amps

.292 amps x 1.15 for 85% efficiency = .335 amps @120 volts

____________________________________

Part 2:

12v27Ah battery =120v2.7Ah battery

_____________________________________

Part 3:

2.7Ah/.335amps=8.05 hours from the 12v27Ah battery, efficency loss already included from inversion. 

_____________________________________

Part 4:

Moral of the story:  even the old ecocharge 12v7Ah batts for the AD1K will run this thing for 2 hours.

Just in case anyone doesn't want to spend the big bucks on a power inverter, my palm size 75 watt inverter ($25) appears to work perfectly, $30. I ran the Tas. for 2 hours off my 12AH ($30) battery and it still registered full. Very happy so far with this low cost DC option.
