I tried Gearslutz on this, but I figure there are probably a lot of people on here who are familiar with the FR-2 as their recording machine.
So, I just bought a Fostex FR-2 (not LE) for field recording. Got the unit from ebay for a deal. But when it arrived and I plugged in my mic to test it out, I noticed that it was just LOUD - full of noise. I thought maybe it was the room, but I ran some side-by-side comparisons and found that this thing just has tons of noise in the recordings. Is this normal for a unit like this?? Or did I maybe buy a faulty unit?
I ran a test... I set up a Rode NT-4 (stereo mic) in an enclosed space with a small speaker. I played a finger-snap sample through the speaker (to match volumes) and let the mic record the silence. I recorded with both my computer's interface, an Echo Layle3G, and through the Fostex FR-2. Both were powering the mic with phantom power, not the 9v battery option.
The results showed that I was indeed right... the Fostex is adding a ton of noise to my recordings... Here's the side-by-side (both snaps peak at the same volume):

Even just looking at both the recordings on a spectrogram, you can see a big difference:
Echo 3G:
Fostex FR-2:
The Echo recording sits at about -52db. The Fostex is sitting at -44db.
So is this right?? Is this part of the unit? Maybe just comes with field recorders that they won't be as quiet as a computer's preamps? Or did I just buy a busted unit? I'd expect that a $1000+ field recorder would have quieter preamps than a $300 audio interface...
