Topic: Edirol R-09HR - Part TWO

[udovdh]

If it is to high, set it to 1.
It is just a number. Not a straight dB scale.

I have been using the default 40 (line in). I am highly confident that this setting is providing excellent S/N ratios. BTW: It's a line-level input so I am not sure at unity gain (if that even makes sense for this input) or being 10 units either side of it (30 to 50) will make any real difference.

Indeed. The performance of the amplification/attenuation will be quite OK and maybe deteriorate at the edged of the range. Dunno, not sure. Maybe additional graps can give more insights.
I mean: a few numbers/dB's up or down won't make a big (audible) difference in quality (SNR, THD, etc).
(I did not start the unity quest...) I just set the device for the value that gives me nice levels and some headroom.
This means, in my case, I have to attenuate I guess. So no unity at all for me.

40? That`s basically my setup.
The only thing that really matters to me is stay away from digital attenuation ( the set to 1 or lower set ups sugestion is something I wouldn't do). Several respected TS members have made it clear: if you have to attenuate, use your preamp, not your recorder.

Please read the datasheet for the codec used in the HR. Not much digital attenuation for the HR that I could discern:

The analogue PGA has a range of +24dB to -21dB in 0.5dB steps. The digital gain control allows
further attenuation (after the ADC) from -21.5dB to -103dB in 0.5dB steps. Table 15 shows how the
register maps the analogue and digital gains.

Combine that info with the review at Sonic Studios, stating:

LINE  +28 dBu  -12 dBu

and default level (53) being extrapolated to be at around 2 dBu for 0dBFS.
If the default level is indeed unity levels beyond 11 or so would not be analog attenuation.

This would mean that you have to go to the very extremes of attenuation to perhaps find digital attenuation. (this being unnecessary because of the codec's 40+ dB gain/attenuation range)

Maybe others can verify and confirm?
BTW: In my case there is no pre.

Last night, I recorded the first act at 44 and the second act at 42.  Came home with beautiful levels . . . . won't even need to touch them.  Moderate sound level at the show:  It was Los Lobos and Los Lonely Boys.  I was centered in the 15th row.

Here's a good sample of the R-09HR with quality mics and preamp - Eric Idle with the Houston Symphony. 

http://taperssection.com/index.php/topic,107777.0.html

The symphony is were 24 bit really shines - the dynamic range is huge.  The R-09HR sounds pretty good to me and I'm happy with the results. 

Note - nothing has been done to the 24/48 fileset other than fades.

enjoy!
