I know this has been discussed a little previously, but I REALLY, REALLY would like to run off of rechargeable AAs for most of my gigs if possible. I've got the DVD batt working great, but if I could ditch that, plus the switch from R4+DVD to R44 with no DVD, I'd be one happy camper.

So, anyone else care to share runtimes of off AAs? I've been getting 2:40 pretty regularly, but I just realized mine are 1500 mah, and I see there are ones as high as 2900 mah? I used my AAs for something non-critical, so I think now I might upgrade my AAs in the hopes of that being my R44 powering solution most of the time.

Love this thing more by the day, heh...

I posted my runtime in the other thread I think and now I can't remember what it was...  anyway, with 2650 capacity batteries there can't be many shows where there would no chance at all to do a quick swap from one set to another (being sure to shut down properly first...!).  Actually I find the batteries a bit hard to whip out quickly - a piece of ribbon under the first set loaded at home might help to yank them out in one go.

there are 3 of us here in Austin that could put together a comp.  Rick (stock) and Drew (Oade mod) both have the recorders.  Larry and I have the same mics (AKG 483's).  We just need to figure out a show we can all make if to.

I saw that earlier but was surprised that your runtime didn't seem that much better than mine despite the fact my mah is much lower...

So how do you like the mod? Does Doug have plans to offer any of the other r-4/pro type mods in the future or does the R-44 limit what can be done in there?

I have yet to hear a "mod" that makes the unit sound decent...

Charles, You really think so? I was toying with the idea getting one to play with SBD/matrix recordings whenever you, Craig, or Derek were not in the mix with your 744s. The thing looks cool, and it's a nice small footprint.

Just curious Charles does a 7xx sound decent on it's own?

I've yet to hear a modded r44. I'll always run a pre in front of any recorder I run.

Running time would depend on phantom current of the particular mics in use I suspect.

Call me stupid - but when late last night I was testing whether the R-44 does bit-perfect digital input, and it was coming out not at all right, I had the MS effect on...

From which first of all we can see that effects will affect the digital input, which is worth knowing.

Second, the digital level controls do not affect the digital input, which is also worth knowing (and of course that's the way it should be).

Third - and most important - when I record one minute from a CD into the R-44 via spdif, then rip that CD into my DAW and invert it against the R-44, I get silence - the spdif recording is bit-accurate.

For proof here's the readout from Audition for the mixdown of the two files, one inverted against the other -

   Left   Right
Min Sample Value:   0   0
Max Sample Value:   0   0
Peak Amplitude:   -inf dB   -inf dB
Possibly Clipped:   0   0
DC Offset:   0    0
Minimum RMS Power:   -inf dB   -inf dB
Maximum RMS Power:   -inf dB   -inf dB
Average RMS Power:   -inf dB   -inf dB
Total RMS Power:   -inf dB   -inf dB
Actual Bit Depth:   float

Using RMS Window of 50 ms

Eureka!  Sorry for the scare last night.  Never do stuff late.
