I suppose we continue on a new thread.  Mod's feel free to correct this if necessary.

FWIW, I have found that the trim adds up to 28dB of gain. Each increment seems to be 1 dB. Setting 0 mutes the input.

The same 28dB of gain is available on all input modes (mic low/high, line).

My measurements of the gain range for each mode are less accurate. But it is approximately:

mic low: 17 dB (17-45dB)
mic high: 42 dB (42-70dB)
line: 12 dB (12-40dB)

Still wondering how mic low sounds compared to line.

I've only used the internal mic pre's up to this point.   
I'm wondering how the gain structure is handled thru the line in input.  Does the input control attenuate the signal, or add gain as the input is turned up?  In a day or two I'll have DPA 4060's and a MMA6000 pre in hand.  I'll  set the general gain range using the incremental controls on the MMA6k and fine tune with the line in control on the R-09.  Question is: Am I better off shooting for the lower range of the line in control or the higher range?

Question is: Am I better off shooting for the lower range of the line in control or the higher range?

My gut says lower range..  We still don't know if that is analog gain or, as you mention, attenuation or if it is digital gain applied in the A/D stage.

Another important question is for quiet sources when running input > line in (schoeps > rmod > r09 mostly in my case).. Is it better to run no r09 gain and add it in post or is it better to run r09 gain.. Given the similar gain structure of mic-low and line, I'm wondering about that choice too.

I'm pretty close to completing a pair of stubbie xlr > 1/8" cables so I can test out of the v3 and bg1..

What's the output of the rmod? Do you know? When I was runnung Schoeps VMS > iRiver, I set the VMS at +10db and adjusted the levels via iRiver... I never had to do more then +/- 3db to get the levels right. I would think if you don't have to use the R-09's gain to much is should be ok to use.

Is it possible to merge in this topic: http://taperssection.com/index.php?topic=57815.0 ? Thought it might be useful for some.. me included

Recorded  more shows this week with my R-09.

A few more thoughts.....been using energizer lithiums
getting 8 hours record time with these, but i noticed when the
batt display finally comes off of full charge, it only takes about
20 more minutres until they are dead. The first few days when i was
playing around with the thing i used duracells and the batt display
showed a more accurate slower discharge.

Also swapped out cards during a show with the r-09 on, first card out
second card in, pressed record twice.....maybe i missed 5 secs of applause.

Finally did a much quieter show than my normal loud rock show
so i used my 4061's > mma6000 > r-09 . Quiet stuff +18 db on the pre.

Did you change the battery setting in the setup - going from the alkalines to the lithiums, or did you leave it the same?

Left it the same, only changed it once when i tryed out re-chargables, then changed it back.

Thats probably due to the meter only being calibrated for standard AA batterys or NiMh, there is no option for Lithiums.  They all have different discharge voltage characteristics.

Yep, and it's very similar to the way the d100/m1 couldn't accurately handle battery indicator level using lithium AA's as well.

With my setup 4023>sx-m2 @ +6dB, I had the R-09 line input level at +16 for Journey and +12 for Def Leppard about 7th row in front of a stack. I don't plan to run the sax any hotter than +6dB based on this first time out.

I don't plan to run the sax any hotter than +6dB based on this first time out.

Why? Why not set the R-09 to 0 (or +1) and use the sax to control the levels? That's my plan.

I've found the sax sounds better at lower levels. Controlling the levels is a bit restrictive with the R-09 because you can't change left/right separately like on the sax, but since I stealth with the sax in my pants, it's much easier to do the levels with the R-09.

I have one coming to my local SamAsh for me this weekend, but came across something on one of the other R09 threads here that disturbed me. Does this unit allow you to monitor while recording? One of the other posts mentioned that it might only allow monitoring after recording, not during, and that sort of scares me. I do prefer to check my recording from time to time, making sure that there is no noise in the signal path that my level meters would not detect. I'm not neurotic about it, but I would prefer to make sure all sytems are still go while the recording is happening.

Well yes, that makes sense!
