Topic: Edirol R09HR

[bgalizio]

Has anyone with an R-09HR in hand done any of the following tests:

1. Opened up the R-09HR to see if the input jacks are secured.
2. Found what the "unity gain" setting is.
3. Done a blind A-B comparison of the ADC with the R-09 (ie: running line-in to each unit, same source material, same bit depth and sampling rate, same overall levels).

That's what I'm wanting to know.

Just tell me what chip(s) are inside.  I want to see if it is an improvement over the original R09.  Preamp self-noise, in particular.  In all other aspects I'm happy with the original R09.

Just back from taping a band called Big Dave. Finally decided that maybe using a pre at really loud shows was unnecessary, so went CA-11s > R09HR mic-in.

My ears are pretty screwy, so no real point in fiddling with the results yet, but it sounds pretty good to me. Will get samples up tomorrow if possible.

The show was most excellent, btw.

Congrats for leaving unnecessary equipment home!

Someone else will open one.
Unity gain is less important than on the R09. Selfnoise should be even lower on the HR. Default gain is 2 dBu at 40.
And it sounds good via line-in. I have no audiophile ears to compare with the R-09 which also sounds good.

Hehe... it was a royal pain, too many shows where my batteries died after 40 minutes, mid song, there goes the quality.



Might have to invest in a battery box, not sure how long the HR will power my mics.

Yes, if/when I get an R-09HR, I will not open mine up for fear of screwing things up (and possibly voiding the warranty).

I think "unity gain" is no less important than on the R-09. The idea isn't about self-noise, it's about not adding or subtracting gain from the original signal.

Nice to hear that it sounds good. I'd still like to hear a blind comp, even if I can't tell the difference between the two.

New sample, from my recording of Big Dave last night. Alas, I don't know the name of the track yet.

http://www.megaupload.com/?d=LKAQKKFM

Went CA-11's > R09HR mic-in, ran at input 45. Turned out nicely, I think.

Nothing done to the wav apart from a slight volume bump (amplified by 1.4db in audacity) then flac'd.

Hope I'm not bothering you.
Do you have those recordings at archive.org? I'd love to hear those samples, but it seems to be impossible with megaupload.
Thanks in advance

I think it's about recording with the highest possible resolution. Peaks just below 0dBFS.
With 24 bits you can relax a bit but the idea still stands.

Unity gain can't help here: mics -> BB -> recorder.

I disagree, the R09 had/has line in input issues, and this one will have to be tested against the same concern

This has nothing to do with the 24 or 16 bit settings, it has to do with the deck adding gain or taking out gain on its own

Wow, that sample sounds great!

big Dave aren't on the archive, I don't think. It was only their second gig.

I can do a yousendit or a sendspace or something this evening. Will put a few other tunes up, too.

With what do you disagree? Your arguments look confused.
Mechanical stability is different from electronics quality. The latter is what we mostly can hear. The first if the machine is broken.
The HR is supposed to have lower noisefloor.Not just lower mic in noisefloor.
What line issues do you mean? loose jacks or noise peaks?

This has nothing to do with the 24 or 16 bit settings, it has to do with the deck adding gain or taking out gain on its own

You'd rather not add or reduce gain and record with increased headroom? If so you're wasting bits.
