how long does it take to burn a cd of your project for backup?
It depends on the size of the file... I recently did a wav back-up of a 17:00 thing on 16 tracks -- took up 1.3 gigs of space across 2 CDR's (I'd say it was about a 15 minute burn.) But I usually do :60 second commercials that can be backed up in about 2 to 3 minutes. The burner on the VF160 is a plextor (at least on mine). Very, very accurate. The 17 minute stereo master had zero errors (I don't mean skips, I mean ANY errors at all -- even commercial discs can have some errors, but my VF160 rarely does, ever)
looks like no usb or other interface, so it's cd only?
There is S/PDIF in/out and ADAT in/out, if this helps.
what's that row of buttons above each fader?
The buttons above the faders arm each track.
how do you adjust pan on a track, (since there's no obvious pot to turn)?
There is a PAN button that gives a visual image on the LCD of eack track's pan position. You select the tracks, via the fader buttons, and rotate the jog wheel.
it has 2 inserts, so where do they route to?
Tracks 7/8.
can you hear the disk running?
Barely. This is a very quiet unit -- no fan. Not dead quiet, but extremely quiet compared to some others.
it has 2 xlr's so, that means it has only 2 inputs of preamps with phantom power?
Yes.
any other things you wish you knew before you got it?
This is a very solid performer capable of great recordings. Buy the 8051 footswitch for punch-in/out. Easy as can be and extremely clean. I don't think there's as good a machine for the money out there. These are setup to behave almost like analogue tape machines -- no need to save as you go, or optimize the disk or defrag. The Fostex's do that on the fly and when you want to stop, just switch it off. It is possible to make the system freeze by pushing command buttons too fast during edits (not unique to the Fostex), but in a year and a half of constant use I have never lost data, ever. If you yanked out the plug during a recording, that might cause some data loss, but by and large these are very well thought out machines.
the ex version is out, what's the diff?
