Bit Depth
Some older Avid workstations support only
16-bit audio. Make sure you consider the follow-
ing when you are starting a new audio session:
• For maximum compatibility when using a
Pro Tools workstation to share audio files and
sequences with older Avid workstations in an
ISIS system, set the bit depth to 16-bit in the
New Session dialog box when you are creating
new session files.
• When using a Pro Tools workstation to share
audio files and sequences with either
Pro Tools workstations or current Avid work-
stations in an ISIS system, set the bit depth to
either 16-bit or 24-bit (depending on your
project requirements) in the New Session dia-
log box when you are creating new session
files.
ISIS Client Performance and
Guidelines
Avid and Digidesign have tested Pro Tools and
Media Station|PT client performance in an ISIS
environment using a single ISIS engine contain-
ing 16 storage blades grouped as a single storage
group. Additional configurations have not been
tested at this time.
An individual ISIS engine containing 16 storage
blades organized as one storage group can serve
the following clients simultaneously:
• Up to nine Pro Tools workstations, each of
which contains:
• Up to forty-eight audio tracks with 48 kHz
24-bit audio
• One DV25 or DV50 video stream
– and –
• Up to two Media Station|PT workstations,
each of which contains up to two DV25 or
DV50 video streams
Compatibility and Performance
Actual performance depends on specific config-
uration and program material. More configura-
tions will be announced as they are tested. For
the latest information, see the Avid Unity ISIS
compatibility pages on the Digidesign website

tion on supported Pro Tools systems and
