FD-4, here.
It sounds really bright and good clarity, but I'm less than thrilled with it's design and features.
The A/B AUX OUTs, [either/or configuration] are rather lame, as compared to an actual dual Aux Out.
The INPUT/TRK MONITOR, [either/or configuration], is less desirable than other cue monitors I've seen.
I don't like the FD-4's backlit LCD display, as much as other designs.
I don't like as much being on an external disc setup, Syquest EZ-Flyer 230, with no internal disc [factory installed upgrade], but somehow I prefer removable media, anyway.
I wish the FD-4 might have had a cartridge drive/removable media embedded in it, like the Tascam 564 and
Yamaha MD-4, 'cept not ATRAC encoded Minidisc.
I'd envision the Fostex to need something like Iomega or Syquest 1Gb uncompressed/pc format discs, removable media.
Of course, if they geared Minidisc to record 16/44.1, uncompressed pc-format data, then MD would be acceptable too. I estimate the raw MD data space to be capable of holding about 14 minutes per disc, at uncompressed 16/44.1, for the 140mb Minidisc. Of course, that development will never occur.
I've scoped the inside of the FD-4, hoping for a quick & easy internal hard disc upgrade, but it turns out the connector is not even on the board. I'd have to get the right connector & solder it on myself, before the FD-4 would accept an internal disc. Or, have Fostex do the HDD upgrade.
Overall, it's a clean, functional unit, the features of which I'm not 100% pleased with, but just based on sound quality, I am very pleased. It's as easy to use as any portastudio-like clone should be.
Ditto, the MTC sync. Although I've not done sync with two Fostexes, I've synced
the Fostex FD-4 to the Tascam 564. Using the handy master/slave function of MTC on these units is a low-budget way of doubling your soundtrack capacity. Plus, if you really like the FD- series, you'll have twice the fun with two of them!
It's a really great sounding recorder, and features are good, but not topnotch like Tascam's. However, for the price, you can't beat it.
FD-4 & FD-8, alike.
Rock on!
