Fostex VC8

Howard	Fostex VC8 I just purchased one of the Fostex VC8 20 bit 8-channel analog/lightpipe converters. This plus the 4 analog ins of the Core2 gives me 12-channel input. It will be put to the test very soon as I'm starting a CD project mid-november. Will be recording: Drums Percussion (Congas & toys) Upright bass Nylon string & Electric guitar Vocals. Running the Core2 in a 850mhz PIII/VIA PC with 2 IBM 7200rpm 40gig drives. Plextor CDR, Turtle Beach Fiji w/Digital I/O. Had to modify the older VIA Apollo BIOS with a BIOS tweak utility to gain maximum performance. Runs great now, never and pops or clicks.

Fostex VC8

I just purchased one of the Fostex VC8 20 bit
8-channel analog/lightpipe converters. This
plus the 4 analog ins of the Core2 gives me
12-channel input.

It will be put to the test very soon as I'm
starting a CD project mid-november.
Will be recording:

Drums
Percussion (Congas & toys)
Upright bass
Nylon string & Electric guitar
Vocals.

Running the Core2 in a 850mhz PIII/VIA PC
with 2 IBM 7200rpm 40gig drives.
Plextor CDR, Turtle Beach Fiji w/Digital I/O.

Had to modify the older VIA Apollo BIOS with
a BIOS tweak utility to gain maximum
performance. Runs great now, never and pops
or clicks.

My question:

The Fostex box uses 20-bit converters. When recording at 24-bit in Cubase am I getting 20 or 16 bit resoulution. In other words, how do the Lexicon Core2 drivers deal with 20-bits. I know that some 20-bit audio cards manage by recording the last 4-bits (of 24) as zeros, but do record 20 bits of data.

thanks...
