Edirol R-09HR - Part FOUR

[su6oxone]

So I finally did a battery test using 2700mAh Sanyos and recording at 24bit/96khz with the LCD on continuously at a brightness of 1...

7 hours and 2 minutes!

Not too shabby.  I'll test later on with 24bit/44.1khz (which is what I always record at).

What software version are you using? I'm still on 1.04 and mine chokes on 96/24 after the first 2GB file. Transcend 8GB class 6 card.
I think I went 10 hours on Duracell 2650mAh batteries at 44/16. I like this recorder.

1.06 and also using a Transcend class 6 card (16gb).

I just version up'd to 1.06 and testing at 96/24... doesn't appear to be choking....so far records a couple 2GB files and continues.

It'd be interesting to do a bench test comp:

source output > good pre amp > r09 peaking at -12
source output > good pre amp > r09 peaking at -1

You could do this two ways - levels adjusted at the pre-amp, and levels adjusted at the r09 only (though I find comps with more than two files do not get as much participation, etc)

Then tweak the gain so they both peak at 0, and let folks vote on which sounds better.

Athough a comp would be interesting to do, technically speaking it's NOT a good idea to drive VU peaks near maximum on battery powered decks.

-1 dBvu is typically very near the supply rails of the device where non-linear distortion has best chance of occurring producing a lower quality recording. 

If recording at 24 bit depth, no reason for driving VU anywhere near maximum and peaks near -12 dBvu seems a wiser tact for having less chance of distortion with adequate headroom for live events.

there are definitely problems with at least a couple of gear combinations, and possibly more, when using the r09hr as a capture device.

1) mics > eaa psp2 > r09hr
2) schoeps mk(x) > remote cables > nbox > r09hr

freelunch and i both own an eaa psp2, which at it's lowest setting outputs ~22db of gain.

the other preamp i, and others use with our schoeps mk(x) capsules, is called an nbox.  it is a boutique, custom built unit which provides power to the schoeps mk(x) capsues, as well as provides a fixed gain of ~18db.  it interfaces with the capsules via proprietary remote cables which can only be used with the nbox, so swapping the power source / preamp out of the chain is not an option.

i for one, am not going to get rid of either preamp because they operate and sound great, and their design is not flawed, like you suggest.  if the r09hr proves to be a deck that cannot handle their output, i'll simply buy a deck that will.

Did anyone find out whether any of the available small decks can handle this output?

Using an attenuator between the fixed gain preamp and the recorder to pad the level down to what the recorder can handle should eliminate those distortion problems.  That will effectively 'turn down' the fixed gain of the preamp by the value of the attenuator.

I just received my Edirol in the mail the other day. I am going to be recording some stuff next week.  I need some help.

There are allot of setting on this where should they all be?

Ive been looking at Core's website for mics for stealth any suggestions?

Anything else I need to know about?

Thank for your help.

Congrats on the purchase, you will like it a lot.  As for settings...

1. Record in 24 bit.
2. 45ish for the recording level
3. Everything low/off on the back.

As for mics, I'd seriously consider picking up a set of CA-14 and 9100 preamp.

I would also recommend the SP-TFB-2 http://www.soundprofessionals.com/cgi-bin/gold/item/SP-TFB-2

They are great binaural mics, stealthy, and compliment the R-09HR very well!

Running firmware version 1.06 without problems for a month now.  Great deck but I'm liking my D50 better when going mic in is called for...

[swordfish]

Newbie's question where do you find the 1.06 Firmware?
