Pro Tools LE uses your computer’s CPU to
mix and process audio tracks (host processing). Computers with faster clock speeds
yield higher track counts and more plug-in
processing.
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 Digidesignqualified computers, operating systems, hard
drives, and third-party devices, refer to the latest
compatibility information 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 periodically defragment your audio drive to ensure
continued system performance.
Table 2. Required hard drive space for audio tracks
Number of tracks and length16-bit at
44.1 kHz
For a list of qualified hard drives and SCSI host
bus adapters, 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 recommended. Recording and playback on system
hard drives results in lower track counts and
fewer plug-ins.
Hard Drive Storage Space
Mono audio tracks recorded with 16-bit resolution at 44.1 kHz (CD quality) require approximately 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 drive space for certain track numbers and track lengths, to help you estimate
your hard disk usage.
Make sure to complete and return the registration card included with your Pro Tools Mbox
system. Registered users will receive periodic
software update and upgrade notices. Refer to
the registration card for information on technical support.

Configuring Pro Tools LE
Pro Tools System Settings
To change the Hardware Buffer Size:
1 Choose Setups > Playback Engine.
Pro Tools LE allows you to adjust the performance of your system by changing system set-tings that affect its capacity for processing, playback, and recording
In most cases, the default settings for your system provide optimum performance, but you
may want to adjust them to accommodate large
or processing-intensive Pro Tools sessions.
Hardware Buffer Size
The Hardware Buffer Size (H/W Buffer Size) controls the size of the hardware cache used to handle host processing tasks such as Real-Time AudioSuite (RTAS) plug-ins.
◆ Lower Hardware Buffer Size settings reduce
monitoring latency, and are useful when you are
recording live input.
◆ Higher Hardware Buffer Size settings allow for
more audio processing and effects, and are useful when you are mixing and using more RTAS
plug-ins.
In addition to causing slower screen response and monitoring latency, higher
Hardware Buffer Size settings can affect the
accuracy of plug-in automation, mute data,
and timing for MIDI tracks.
Playback Engine dialog for Mbox
2 From the H/W Buffer Size pop-up menu, select
the audio buffer size, in samples.
3 Click OK.
CPU Usage Limit
The CPU Usage Limit controls the percentage of
CPU resources allocated to Pro Tools host processing tasks.
◆ Lower CPU Usage Limit settings limit the ef-
fect of Pro Tools processing on other CPU-intensive tasks, such as screen redraws, and are useful
when you are experiencing slow system response, or when running other applications at
the same time as Pro Tools.
◆ Higher CPU Usage Limit settings allocate
more processing power to Pro Tools, and are
useful for playing back large sessions or using
more real-time plug-ins.
Increasing the CPU Usage Limit may slow
down screen responses on slower computers.
◆ With Pro Tools 6.x, the maximum CPU Usage
Limit is 85 percent for single-processor computers, and 99 percent for multi-processor computers. (The 99 percent setting dedicates one entire
processor to Pro Tools.)
Getting Started with Mbox14
To change the CPU Usage Limit:
1 Choose Setups > Playback Engine.
2 From the CPU Usage Limit pop-up menu, se-
lect the percentage of CPU processing you want

3 Click OK.
DAE Playback Buffer Size
The DAE Playback Buffer Size determines the
amount of memory DAE uses to manage disk
buffers, which affects system performance.
◆ Lower DAE Playback Buffer Size settings can
improve playback and recording initiation
speed. However, a lower setting can make it difficult for slower hard drives to play or record
tracks reliably.
◆ Higher DAE Playback Buffer Size settings can
allow for a higher density of edits in a session.
However, a higher setting can cause a time lag to
occur before playback or recording begins. It can
also cause a time lag to occur when you are editing during playback.
To change the DAE Playback Buffer Size:
1 Choose Setups > Playback Engine.
2 From the DAE Playback Buffer pop-up menu,
select a buffer size.
3 Click OK.

continued system performance.
If you are using a SCSI hard drive, you can initialize your drive with the utility software
named ExpressStripe (Mac OS X) or ExpressPro-Tools (Mac OS 9) from ATTO, included on the
Pro Tools LE Installer CD-ROM. If you are using
an ATA/IDE or FireWire hard drive, initialize
your drive with the utility named Disk Utility
(Mac OS X) or Drive Setup (Mac OS 9), included
with your Apple System software.
Getting Started with Mbox18
Avoid Recording to System Drives
Although Pro Tools will let you record to your
system drive, this is generally not recommended. Recording and playback on system
hard drives results in lower track counts and
fewer plug-ins. You should record to system
drives only when necessary—for example, if
your computer system has just one hard drive.
