SCSI hard drive (or a removable IDE HD in place of the CD-RW drive). All you need to know is if
their system supports BWAV (timestamps).
If not, you will have to export all the tracks starting at the same point (it takes more space). DPS24
V1.50 supports both modes. Also, you will be able to choose to export stereo tracks as a single
stereo WAV file or as two mono WAV files, even if you export 24 tracks at the same time.

ProTools Format / Import – Importing From MAC
I have a backup of a pro-tools session (from a Mac) on CD. I am able to
read the files on my win pc, and I wish to convert each track to wav (for
xfering to the DPS). I'm fairly ignorant on the file format, I thought it
was AIFF (24-bit). Any one have any helpful suggestions.
The audio file format used by ProTools changed in recent versions of ProTools (since PT 6, I think).
The original native format is SD2 (Sound Designer 2).
This is a Mac format. SD2 is a variation of AIFF: same audio data, but with additional information
such as Timestamp, Overview (the waveform envelope for display), ...
On Mac versions of ProTools, it is also possible to import/export tracks as WAV files. However,
Broadcast WAV (with Timestamp) is only supported by PT after PT 5.1.
For information, PT cannot combine 16bit and 24bit SD2 audio files in the same Session. This has to
be decided when the Session is created and any imported audio has to be converted to the format of
the Session.
Since PT 6, the native audio file format is now BWAV with Timestamp, even on Mac.
If you are converting from SD2 to WAV, make sure that the conversion software also translates SD2
Timestamps into BWAV Timestamps, or that all the tracks start at the same time.
What is so important about Timestamp?
Without Timestamp, all tracks have to be rendered to start at the same time (or at zero in some
cases) in order to "line up" when imported. This is wasting a lot of space and time, especially when
using CD-R's. For instance, if a track contains only a short piece of audio at the end of a 5 minutes
song, it needs to be rendered as 5 minutes of "recorded" zeros. As a result, a multitrack export that
would fit on a single CD using Timestamps might require 2 CDs to fit all the "rendered to zero" tracks.
If you get an multitrack export with tracks that are not starting at the same time, without Timestamps,
you would need to find the start time of each track manually, and this can be difficult and often not
accurate.
Timestamps are Sample Accurate.
Another important point when Exporting from a Mac is to make sure that the media is not in Mac HFS
format. CD-R's should be in ISO9660 standard format. (if you can open the CD on your PC, it is OK).
Hard Disk or removable disks should be in FAT32 or FAT16 format (any media under 2GB need to
be FAT16, as defined by Microsoft).
Macs support FAT16 and FAT32 via the FileExchange/PCExchange control panel.

S/PDIF & TDIF 24-bit Transfers
Does the S/PDIF in on the Deeps receive 24 bit data? In other words if I
am transferring two tracks from a Tascam DA 78 from the S/PDIF out to the
S/PDIF in on the Deeps am I getting a 24 bit transfer? (Does pro/consumer
