Klas, I just helped to do a little write-up for Electronic Musician
comparing some of the latest recorders. We did three different tests,
recording some dialog, a snare drum, and some night ambience. The
night ambience was recorded with a pair of Earthwork omni's.
Those are pretty quiet mics, so what we were hearing in noise
difference was mainly the input stage (instead of saying just mic
preamp, since the A/D convertor can theoretically be significant to
what you hear as well).
There was a HUGE difference. I won't propose to know exactly what I
was hearing, but the 722 and the Fostex FR2 were fairly quiet, and
both Marantz units that were tested were VERY noisy. Hiss. Lots of hiss.
I honestly don't know where and at what stage it's all happening. Is
the unit just adding additional noise?
When we did the dialog test, since the dialog was loud enough, the
noise on each of the devices wasn't really an issue, the noise floor
was down there enough that it didn't really matter.
I'm not an overtly technical person, so I won't argue too much, but
there is most certainly a difference between a minidisc recorder, a
Sony DAT, my 722, my HHB, all of them. A lot of time too I notice not
even so much a 'level 'difference in the noise, but a different sonic
character, what seems 'smoothest', less distracting.
The thing is, you take a very quiet mic, like the Telinga, Schoeps,
etc. But then to record something quiet, you're applying 60dB of gain
or more, so that noise floor is coming up, but also the device starts
to add it's own noise, and I do think it's cumulative.
Anyway, not to open this can of worms again....
