Here are notes from my review, posted here in July 2007. --oryoki


First, when you format the Compactflash card for use in the FR-2LE, you spe=
cify the bit depth and quantization rate to be used (like 24/96).  These se=
ttings are stored in a text file on the flash card.  If you want to change =
this setting (say, to MP3 or 16/44.1), you have to re-format the flash card=
.  The formatting will lose any data already on the flash card.  This is a =
quick format, just a few seconds.

Second, the maximum file size is 4GB.  When the recorder gets to 4GB, it ju=
st saves the file and stops.  4GB is space for six hours of continuous reco=
rding in 16/48, but only two hours at 24/96.  This is not an issue for most=
 nature recording scenarios, but could be a problem if the recorder will do=
 double duty as a concert recorder.

Third, the FR-2LE has only one bit depth for MP3.  It's 192kbps continuous =
(no variable rate).  Recording at this rate, a 1GB card can hold approximat=
ely 11 hours of recordings.  You'd need to change batteries or run from an =
external power supply to record for such a long time.

Fourth, you can't erase any tracks from the machine in the field.  You can =
remove tracks from the edit decision list, or change the order of the track=
s in the list, but you can't delete any.  When you attach your flash card t=
o a computer, you can delete if you want to.  Or you can format the card in=
 the recorder.  But an individual file can't be deleted in the recorder.

Fifth, the FR-2LE records in stereo only.  This is wasteful of storage spac=
e if you are recording with a single mic.  I guess you could use a "Y" cabl=
e to send the mono signal into both channels of the recorder, and then reco=
rd at different preamp levels.

I think these last two design decisions are part of a strategy Fostex has t=
o reduce errors when the machine is being used by a less-experienced record=
ist, perhaps a news reporter.  An audio technician sets up the recorder, in=
cluding the flash card, in the shop.  The FR-2LE stores settings like ALC o=
n/off, high pass filter on/off, Input mode, digitizing rate, phantom power =
on/off, and so on, in non-volatile memory that retains the settings even wi=
th the battery pack removed.  The Compactflash card holds information like =
the digitizing rate, the project name or reel number, and pointers to the s=
tart and stop points of any existing tracks and cue marks.

Once the FR-2LE is configured, the field recordist doesn't need to think ab=
out settings, just when to push the Record button.  It doesn't matter which=
 XLR jack a mono mic is plugged into. Most relevant settings are visible on=
 the LC screen if you want to check.

I'm sure Fostex worked a long time with customers like radio stations to co=
me up with this fail-safe arrangement.   The FR-2LE forces you to work a pa=
rticular way to maximize the likelihood that your recordings will come home=
 intact, and in the format you want.  But some people will find these restr=
ictions burdensome.

These points aside, the FR-2LE seems to be a great machine.  The preamp is =
quiet, the controls are easy to use, the machine is well-designed for use i=
n a shoulder bag, and the Tamiya RC3600 NiMH battery solution is good for 8=
 hours of run time.
