Chapter 1: Welcome to Mbox

System Requirements
Mbox can be used with a Digidesign-qualified
Windows or Macintosh computer running
Pro Tools LE software.
Digidesign can only assure compatibility and
provide support for hardware and software it
has tested and approved.
For a list of Digidesign-qualified computers, op-
erating systems, hard drives, and third-party de-
vices, refer to the latest compatibility informa-
tion on the Digidesign Web site
(www.digidesign.com/compato).
Hard Drive Configuration and
Maintenance
It is recommended that you start with a newly
initialized audio drive. You should also periodi-
cally defragment your audio drive to ensure
continued system performance.
For a list of qualified hard drives, visit the
Digidesign Web site
(www.digidesign.com/compato).
Avoid Recording to System Drives
Although Pro Tools LE will let you record to
your system drive, this is generally not recom-
mended. Recording and playback on system
drives results in lower track counts and fewer
plug-ins.
Hard Disk Storage Space
Mono audio tracks recorded with 16-bit resolu-
tion at 44.1 kHz (CD quality) require approxi-
mately 5 MB of hard disk space per minute.
The same tracks recorded with 24-bit resolution
require about 7.5 MB per minute. Table 2 lists
the required disk space for certain track num-
bers and track lengths, to help you estimate
your hard disk usage.
