Is there a battery operated 24 bit Converter?

Tascam US-122 is capable to record stereo programs at the resolution of
24 bits. It's powered via USB so the battery inside your laptop will be
used.
Is not very expensive (about $200, as far i know).
Some other similar USB or FW audio interface may meet your needs.

What kind of digital gozinta does your computer have? And what "budget"
is best? I can't think of a battery powered A/D converter that doesn't
also contain a mic preamp, but if you can stand to lose the mixer or
pad down its output, you might want to check out the offerings as
http://www.core-sound.com. They have a decent preamp/A/D of their own
design that has both coax and optical S/PDIF output, and for less
money, the Deneke InBox, thought it doesn't provide phantom power.

there are a few different options:

My favorite: Grace Lunatec V3: Incredibly pristine and transparent
preamps and great converters. Grace nailed it on this one.

Apogee Mini Me:
Decent mic pres and Apogee's patented converters. Comes in a USB and
Non -USB version:

Denecke AD-20:
Good box for the $$ - really nothing competes with this in this price
range:

We sell custom battery packs for the V3 and Mini Me and the AD-20 runs
off of 9v batteries.

FW Bus Powered Unit:
I really love the Presonus Firebox - nice preamps and really easy to
use.

I forget I am chatting with Mr. Technical☺ Yes, I need a few parts
but I simplified it to my level of thinking.

I took a look a M-audio and firebox. I think I will let it stir for a
few days while the customers check clears but I am covered at least. I
didn’t realize there were so many solutions now a day. All of these
toys were more then I was hoping for.

Have you used the Firebox that Frank mentioned? It looks like a good
option since it is all in one box an I can plug it in 12 volt or into
my computer for power. Also, it has phantom, which is a must.

I’m doing a bunch of pre-production work for a company and I am doing
it on my boat that will be out in the Bahamas on vacation. I don’t
like using the inverter because it makes a lot of line noise so the
battery thing is pretty much a must have deal.

I just want to say again – thanks to all of you guy s here. I would
have been searching for hours without this help.

It can be bus powered, from the firewire port.

i think the new m-audio ram-based recorder thing can be battery
powered, and it has preamps, converters and storage.

i was wondering when they would finally invent the "palm pilot" of
audio recorders!

Anything that can be powered with a wall-wart at less than 600mha can be
replaced with a battery pack of C or D cells very easily. Or any cells, but
AA's or 9volt rectangles will drain fast.

right, I was referring to equipment with DC wall-warts. Thankfully AC
wallwarts are much less common, though I know the insufferable Sherman
Filterbank uses one.

I suppose that enables them to skimp on the design somewhere else. But hey,
the prevailing attitude of this newsgroup is, if an implimentation is
'scientifically sound', we can't criticize it!
