I just purchased some 4GB OCZ class 6 cards.So far so good.....

[EverybodyelsE]

Nice to see one 32gb in there 

[RobC]

I used a 8 GB PNY class 4 with no problems  @  16/44.1  mono x4,  just got 2 new class 6 cards I will be using for 24 bit stuff,  probably stereo x 2

[Ozpeter]

I had an 8GB Transcend die between taking it out of the R-44 and inserting it into the PC.  Sorry if I've already mentioned that.  It worked nicely till then...

[Alex_The_ Frenchy]

I use a 8GB Transcend without any problem.

Autonomy test:
Alimentation: 4 accus Ni-MH de 2650mA)
Luminosity (Display): 4
Buttons: DIM
Light: OFF
Sensitivity: -44 dB (= 15H)
Level: Center(= 12H)
Limiter: ON
Alim Phantom x 4 micros
Folders: BWF 24bits/96KHz
Stéréo x 2

Résults registering on SDHC 8 Go (card changed till 2H): 3H21

Very nice; It's sufficient for me.

so you're satisfied with your NiMH accus, compared to regular AA batteries? What brand are they?
thanks

[Ozpeter]

Here in Australia the only readily available brand of NiMH 2650mAh is Duracell.  And they do provide good performance.

Alex of France seems to have got longer from his than mine in what was I think a pretty similar test - but different mics draw larger or smaller phantom power currents, so anyone's results are likely to be only a broad indication of obtainable battery life.

[sonidista]

I read Varta Power and Professional are good. They even have 2700 mAh.

[Alex_The_ Frenchy]

I use Duracell batteries, like Ozpeter.
The 4 microphones are 2 x B5 (Beyerdynamic) and 2 Sennheiser: ME-62 and ME-64.

The pre-record function was ON too, but I've registered inmediatly.

Hey all. I now have the transparency mod worked out for the R-44. The vintage mod will have to wait until I find the right components that will fit in that tiny box.
The pre amps different in this box from the R4 and R4pro and they don't leave any room for much but I have crammed my components in there for an awesome sound.

It consists of the usual op amp and capacitor changes in the input path. No gain stage changes as it doesn't need it.

is there any way you can mod the gain knobs so they don't click with steped gain

[Busman Audio]

Sorry this is not an option.

I only do the mods I described I don't have time to do odd custom mods.

[RobC]

no problem
