Title: R9HR questions about battery use age and length.
Post by: steve4134 on May 13, 2011, 11:12:11 AM
I am now in  a position where I pretty much need to walk around and record my whole days conversations. I was wondering with an 8 gig card and a fresh charge of sanyo en-loops would i be able to do this ?  I work 9-5. Any advice is welcomed. I am thinking 16 bit but not sure at what wave length.

You might want to use an external battery if you are going to run it from 9-5!  I would probably grab a 16gig card just to be safe.  Also the newest firmware has an eco mode which gives better run times.

Really a  16 gig card ?  I am not looking at 24 bit and i seriously doubt it will even be 44.1.  Thanks for the response keep em coming

If it is important I would rather be safe than sorry!

You will be fine with an 8GB card. Recording @ 16/44.1 will yield about 12h30m of recording time on an 8GB card.

The batteries are a different story. Depending on the mAh rating you *might* be able to squeeze out an 8 hour day's worth of recording but you'll definitely be cutting it close. Turn the screen brightness to the lowest setting. Do you get a lunch break in there somewhere? I'd just bring 2 sets of AA's, switch out at break time and you'll be set.

8GB card is fine if you're doing 16/44.1 (which for just voice isn't really necessary) but I wouldn't trust the deck to run 8hrs even with hi capacity batts.  An M10 definitely would but I'd think the R-09HR won't get you close to that, esp with rechargeables. If you're using its internal mics and its mic power, even less so.

Im going to try and do some testing. I was thinking of using internal mics but also have church 9100s i believe with a  chruch 9100 pre. Yes its just for voice

Or get a Sony PCM-M10 and get around 30hrs of recording ;)

8 gigs at 16/44.1 will give you close to 13hrs.

Great suggestions, but if you are busy having a larger card will allow you to record several days before worring about processing or moving to a hard drive!  I know files sit on my SD card for a few weeks before I transfer them.

The Eneloops (or equivalent LSD NiMH like Imedion) are a good bet as long as you change them at lunch as mentioned. Or keep a charged pair in there as a safety backup to an external battery supply and you can probably run all week.  If its simply voice content and you are recording all day long, consider recording to MP3 instead of WAV. You will be generating massive amounts of data and should seriously consider how you'll handle that once the files are off-loaded from the SD cards.

No doubt. I would try mp3 320k for a day and see how the audio is.

Are you going to use any external mics? That would drain the battery since it MOST likely would need plug in power.

Well after a  few days of testing it looks like i'm getting from 8-2 consistently recording with internal mics at 44.1.  I am not worried about filling up my 8 gig card and haven't even come close. I believe I will do the recommended swap batteries at lunch. I will try mp3 and see how it comes out. I fig if i come out with a 6 gig file and then flac it down to 3 ish  gigs then I can live with that
