Did you delete the 2GB test recording without reformatting the card?

It's good practice is to reformat a card whenever you delete any files from it.  If you only copy the files off the card and have plenty of card space remaining, then you needn't reformat each time.  Delete anything and a reformat is in order.  This keeps the file system on the card clean and non-fragmented.

^ Thanks for your advise Gutbucket

I just bought an used DR2d and I like it very much. Hope to use it in the field soon!

This is a second hand Tascam and it was my first use. I did several tests at home but never formatted the SD card. I always deleted the files manually once the card was in my PC's SD slot.
Will do a complete format next time. Thanks :)

Yeah. Always format with the Tascam. I figure it's the one using the card so it's probably better to let it format.
Also change your files size. I keep mine set to 512 file size.
I figure it's a way to minimize risk. If it errors during a write, I won't loose as much data.
At 24/48 I get about half an hour in a 512 file. I'd rather loose half an hour than 4 times that if I split at 2 gig.
Always looking for Iron Maiden and Papa Roach audio that I don't have.

How much would the batteries last with a Tascam DR2d updated with last firmware and recording in 24/48 using two mics (dual line-in + mic-in) that are powered by either a 9V battery box and a 9V preamp ?
I'm just looking for an order of idea.

Hi, a question for the board, could I use the following battery box/power supply to supply 5V PIP to a pair of mics utilizing the DR-2D's line input and then use the DR-2D's PIP, via the mic input, to supply PIP to another set of mics thereby recording two stereo pairs?

That will work, but you'll have no control over line-in levels while recording, and only 5dB of adjustment prior to recording.  For that reason, you'll probably want a preamp with adjustable gain instead of a simple battery box.

I ran a test with that exact setup described in the quote. I taped a show using two fresh Enregizer Alkaline Power - AA batteries (those are the "standard" Enregizer AA's I think).

Batteries last for 3 hours, 55 minutes and 23 seconds.

I ran a new test with Energizer Ultimate Lithium batteries.



My setup changed a bit as I swapped the preamp for a second battery box :
Tascam DR2d updated with last firmware and recording in 24/48 using two mics (dual line-in + mic-in), each of them powered by its own 9V battery box.

My 16GB SD card is now full. That's already 7 hours, 40 minutes and 43 seconds of music and the battery indicator on the Tascam still shows 3 bars out of 3 !!

Edit: the Tascam finally went out of power after 9 hours, 44 minutes and 55 seconds.

I have been using the Energizer Advanced Lithiums for normal shows (2 to 3 hours) or Ultimate Lithiums for longer shows/festivals.

Just did a run time test a couple weeks ago, primarily as a suitability test of the Powerex precharged NiMH 9.6V in a custom preamp. But because this was an "as typical" real-world test of the entire rig in operation, I simultaneously checked run time of a couple very old but freshly reconditioned Immedion NiMH AA's powering the DR2d.  I posted the results here- http://taperssection.com/index.php?topic=180370.msg2211435#msg2211435.

These were very old NiMH AA's, and the only salvageable pair from a batch of 12 I had laying around.  I attempted to recondition the entire batch in the Maha charger prior to this test.  With the exception of this pair, the remaining 10 batteries all tested bad with overly high internal resistance.  This pair reconditioned successfully to a measured capacity of around 2100 mAhr each and powered the DR2d for something more than 5-1/2 hrs, but less than 6-1/2 hrs.  I take this as positive confirmation of my baseline figure of ~5hrs safe max run time on NiMH rechargeables.  Newer NiMH should provide a larger run-time safety buffer.
