System Requirements and Compatibility

Mbox Pro can be used with a qualified Windows or Mac computer.
A DVD drive is required to use the Pro Tools In­staller disc.
Avid can only assure compatibility and provide support for hardware and software it has tested and approved.
For complete system requirements and a list of qualified computers, operating systems, hard drives, and third-party devices, visit:
www.avid.com/compatibility
MIDI Requirements
Mbox Pro includes one MIDI In port and one MIDI Out port, providing 16 channels of MIDI input and 16 channels of MIDI output.
If you require additional MIDI ports, add a MIDI interface to your system. USB MIDI interfaces work effectively with Pro Tools systems on Win­dows or Mac. Serial MIDI interfaces are sup­ported on Windows systems only.
Hard Drive Requirements
For optimal audio recording and playback, all Pro Tools systems require one or more qualified hard drives.
If you are using an ATA/IDE or FireWire hard drive, initialize your drive with the Disk Utility application included with Apple System soft­ware (Mac) or Windows Disk Management (Windows).
For more information, see Appendix E, “Hard Drive Configuration and Mainte­nance.”
Avoid Recording to the System Drive
Recording to your system drive is not recom­mended. Recording and playback on a system drive may result in lower track counts and fewer plug-ins.

Chapter 4: Configuring Your Pro Tools System 17

Configuring Pro Tools LE

To change the Hardware Buffer Size:
1 Launch Pro Tools.
Pro Tools System Settings
In the Playback Engine dialog, Pro Tools LE lets you adjust the performance of your system by changing system settings 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 buffer used to handle host processing tasks such as Real-Time AudioSuite™
®
(RTAS
) plug-ins.
• Lower Hardware Buffer Size settings are useful for improving latency issues in certain record­ing situations or for improving certain system performance problems. On Pro Tools LE sys­tems, lower settings reduce all input-to-out­put monitoring latency on any record-armed tracks or Auxiliary Input tracks with live in­puts.
• Higher Hardware Buffer Size settings are use­ful for sessions that are using more RTAS plug­ins for playback. These settings allow for more audio processing. They can also be useful to reduce errors on some machines that require a higher buffer size.
2 Choose Setup > Playback Engine.
3 From the H/W Buffer Size pop-up menu, select
the audio buffer size, in samples.
Playback Engine dialog for Pro Tools LE, with Structure Free plug-in installed. (Mbox 2 shown)
4 Click OK.
In addition to causing slower screen re­sponse and monitoring latency, higher Hardware Buffer Size settings can increase the latency caused by RTAS plug-ins, and affect the accuracy of plug-in automation, mute data, and MIDI track timing.
Mbox Pro User Guide18
Host Processors
The Host Processors setting lets you manage multi-processor support for RTAS (Real-Time AudioSuite) plug-in processing.
Used in combination with the CPU Usage Limit setting, the Host Processors setting lets you con­trol the way RTAS and other host-based process­ing tasks are carried out by the system.
For example:
• For sessions with large numbers of RTAS plug­ins, you can allocate 2 or more processors to RTAS processing and set a high CPU Usage Limit.
• For sessions with few RTAS plug-ins, you can allocate fewer Host Processors to RTAS and set a low CPU Usage Limit settings to leave more host processing resources available for automation accuracy, screen response, and video.
• Depending on the importance of video and overall screen response, and on the density of automation being employed, try different combinations of Host Processors and CPU Us- age Limit settings to achieve the best results. For example, to improve screen response in a medium-sized session using a moderate num­ber of RTAS plug-ins, try reducing the number of RTAS plug-ins, but keep the CPU Usage Limit set to the maximum (up to 99% on a single processor system).
To set the number of Host Processors:
1 Choose Setup > Playback Engine.
2 From the Host Processors pop-up menu, select
the number of available processors you want to allocate. The number of processors varies de­pending on your computer:
• Select 1Processor to limit processing to one CPU in the system.
• Choose 2 Processors to enable load balanc­ing across two available processors.
• On systems running four or more proces­sors, choose the number of processors for processing.
3 Click OK.
System Usage Window and Processing
The System Usage window (Window > System Us­age) displays the combined amount of process-
ing occurring on all enabled processors with a single indicator, regardless of how many proces­sors are available in the system. If the System Us­age Window shows that you are at the limit of available resources, increase the number of pro­cessors and adjust the CPU Usage Limit setting.
Chapter 4: Configuring Your Pro Tools System 19
CPU Usage Limit
Host Engine (Error Suppression)
The CPU Usage Limit setting controls the per­centage of CPU resources allocated to Pro Tools host processing tasks. Used in combination with the Host Processors setting, the CPU Usage Limit setting lets you control the way Pro Tools tasks are carried out by the system.
•Lower CPU Usage Limit settings limit the effect 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 RTAS plug-ins.
The maximum available CPU Usage Limit de­pends on the number of processors in your com­puter and on the number of processors you spec­ify for RTAS processing. This value can range from 85% for single-processor computers, and 99% for multiprocessor computers (which dedi­cate one entire processor to Pro Tools).
The Host Engine option determines error report­ing during playback and recording. This is espe­cially useful when working with instrument plug-ins.
You should only enable error suppression if you are experiencing frequent RTAS errors that are interrupting your creative workflow. When er­ror suppression is enabled, you can experience a degradation of audio quality. However, this may be acceptable in order to avoid interrupting playback and recording when working with in­strument plug-ins. Be sure to disable error sup­pression when you need to ensure the highest possible audio quality, such as for a final mix.
To enable error suppression:
1 Choose Setup > Playback Engine.
2 Select Host Engine: Ignore Errors During Play-
back/Record.
3 On Mac, you can also select Minimize Additional
I/O Latency.
4 Click OK.
On multiprocessor computers, the maximum CPU Usage Limit is reduced when you use all your processors (as selected in the Processing pop-up menu). For example, on dual-processors, the limit is 90%. On four-processor computers, the limit is 95%.
Increasing the CPU Usage Limit may slow down screen responses on slower computers.
To change the CPU Usage Limit:
1 Choose Setup > Playback Engine.
2 From the CPU Usage Limit pop-up menu, select
the percentage of CPU processing you want to allocate to Pro Tools.
3 Click OK.
Mbox Pro User Guide20
Error Suppression Options
Ignore Errors During Playback/Record
When the Ignore Errors During Playback/Record option is enabled, Pro Tools continues to play and record even if the host processing require­ments exceed the selected CPU Usage Limit. This can result in pops and clicks in the audio, but does not stop the transport.
Minimize Additional I/O Latency (Mac Only)
When enabled, any additional latency due to suppressing errors during playback and record is minimized to 128 samples. Suppressing RTAS er­rors requires at least 128 samples of additional buffering on some systems. If this option is dis­abled, the buffer is half the H/W Buffer Size, or at least 128 samples (whichever is greater). If you are on an older, slower computer, you may want to disable this option to avoid adverse perfor­mance.
This option is only available on Mac if the Ignore Errors During Playback/Record option is enabled.
DAE Playback Buffer Size
The DAE Playback Buffer Size setting determines the amount of memory DAE allocates for disk buffers. In addition to levels, the DAE Playback Buffer Size shows values in milliseconds, which indicate the amount of audio buffered when the system reads from disk.
The optimum DAE Playback Buffer Size for most disk operations is 1500 msec; Level 2 (Default).
DAE Playback Buffer Size settings lower than 1500 msec; Level 2 (Default) may improve playback and recording initiation speed, as well as preview in context in DigiBase brows­ers. However, a lower setting may make it dif­ficult to play or record tracks reliably with sessions containing a large number of tracks or a high density of edits, or with systems that have slower or heavily-fragmented hard drives.
DAE Playback Buffer Size settings higher than 1500 msec; Level 2 (Default) allow higher track count, higher density of edits in a session, or the use of slower hard drives. However, a higher setting may increase the time lag when starting playback or recording, starting pre­view in context from DigiBase browsers, or cause a longer audible time lag while editing during playback.
Using a larger DAE Playback Buffer Size leaves less system memory for other tasks. The default setting of 1500 msec (Level 2) is recommended unless you are encountering –9073 (“Disk too slow or fragmented”) errors.
To change the DAE Playback Buffer Size:
1 Choose Setup > Playback Engine.
2 From the DAE Playback Buffer pop-up menu, se-
lect a buffer size. Memory requirements for each setting are shown at the bottom of the Playback Engine dialog.
3 Click OK.
If Pro Tools needs more system memory for the DAE Playback Buffer, it will prompt you to re­start your computer.
Chapter 4: Configuring Your Pro Tools System 21
Cache Size
The Cache Size setting determines the amount of memory DAE allocates to pre-buffer audio for playback and looping when using Elastic Audio.
Minimum Reduces the amount of system mem­ory used for disk operations and frees up mem­ory for other system tasks. However, perfor­mance when using Elastic Audio features may decrease.
Normal Is the optimum Cache Size for most ses­sions.
Plug-In Streaming Buffer Size
(Structure Plug-In Only)
This setting appears in the Playback Engine dia­log only if Structure, Structure LE, or Structure Free is installed on your system. The Plug-In Streaming Buffer Size determines the amount of memory DAE allocates for streaming playback from disk with the Structure plug-in. This setting only affects playback if disk stream­ing is activated in Structure’s plug-in controls (see the AIR Virtual Instruments Guide for more information).
Large Improves performance when using Elastic Audio features, but it also decreases the amount of memory available for other system tasks, such as RTAS processing.
Using a larger Cache Size leaves less system memory for other tasks. The default setting of Normal is recommended unless you are encountering -9500 (“Cache too small”) errors.
To change the Cache Size:
1 Choose Setup > Playback Engine.
2 From the Cache Size pop-up menu, select a
disk cache size.
3 Click OK.
The optimum Plug-In Streaming Buffer Size for most sessions is 250 ms (Level 2).
Plug-In Streaming Buffer Size settings lower than 250 msec (Level 2) reduce the amount of system memory used for sample playback and frees up memory for other system tasks. How­ever, audio quality of sample playback may decrease.
Plug-In Streaming Buffer Size settings higher than 250 msec (Level 2) improve the audio quality of sample playback, but they also de­crease the amount of memory available for other system tasks, such as RTAS processing.
Using a larger Plug-In Streaming Buffer Size leaves less system memory for other tasks. The default setting of 250 ms (Level 2) is recommended unless you are experiencing problems with the audio quality of sample playback.
To change the Plug-In Streaming Buffer Size:
1 Choose Setup > Playback Engine.
2 From the Plug-In Streaming Buffer Size pop-up
menu, select a buffer size.
3 Click OK.

About Phantom Power
Most condenser microphones (such as an M-Audio Solaris) require phantom power to op­erate. Dynamic microphones (such as a Shure SM57) do not require phantom power to oper­ate, but are not harmed by it.
Although phantom power can be used safely with most microphones, it is possible to damage some ribbon microphones with it. Always turn off phantom power and wait at least ten seconds before connecting or dis­connecting a ribbon microphone.
When using phantom power, Mbox Pro’s maximum current per microphone is 10 mA.
If you are not sure about the phantom power re­quirements for your microphone, consult your microphone’s documentation or contact the manufacturer.
Headphone A and B Volume Knobs
The headphone knobs adjust the output level of their corresponding Headphone output (A or B).
The Multi button can be assigned to execute sev­eral functions in Pro Tools, including Track Create, Start/stop Record, Tap Tempo, Toggle Marker Locations, and Save Session. For detailed information, see Appendix B, “Using the Multi Button.”
Mbox Pro User Guide34
Dim/Mute Switch
Mono Switch
The Dim/Mute switch affects the output volume for control room outputs as assigned in the Driver Control Panel setup (by default, Line Outputs 1 and 2.)
There are two functions of the switch:
When pushed, Line Outputs 1 and 2 (or the
currently assigned Control Room outputs) are dimmed. When Dim is engaged, the switch LED lights solid.
When pushed and held in, Line Outputs 1
and 2 (or the currently assigned Control Room outputs) are muted. When Mute is engaged, the switch LED flashes.
Power Indicator LED
The Power LED indicates that the Mbox Pro is receiving power from its power supply. Once the light is on, audio can pass in or out of the sys­tem. If the light is flashing, the power is not cor­rect or clock is not locked.
The Mono Button sums the control room out­puts to a mono signal (delivering that identical signal to both speakers) via the Driver Control Panel or the Mbox Pro. When engaged, the Mono LED lights.
Speaker/Source Select Switch
If you push and hold the Speaker/source select switch, it sources Aux Inputs 5 and 6 so you can switch between monitoring Pro Tools playback and monitoring an external source (such an MP3 player).
When pushed, it lets you toggle through the
control room output pairs so you only hear one of them at a time. (For more information on control room output pairs and Speaker/source functionality, see Appendix A, “Using the Driver Control Panel.”)
When pushed and held in, it lets you have
Aux Inputs 5-6 “take over” from Pro Tools - to listen to something such as an MP3 player.
Master Volume Knob
The Master Volume knob controls the output level of assigned control room outputs. You can turn it up to the level you like while playing an instrument, recording into a mic, or while play­ing back audio from Pro Tools.

Making Studio Connections

This chapter provides step-by-step instructions for connecting mics, instruments, mixers, headphones, speakers, and other devices to Mbox Pro.

Connecting Outputs

To hear audio recorded into a Pro Tools session, you will need to connect headphones or an ex­ternal sound system (such as powered monitors or a home stereo) to Mbox Pro. Sound from Mbox Pro cannot be played through your com­puter’s speakers or your computer’s sound out­put.
Connecting Headphones
On the front panel of the Mbox Pro are two 1/4­inch headphone connectors, each with an asso­ciated level control, labelled A and B. Connect up to two sets of headphones for mixing and tracking.
By default, headphone A monitors the Pro Tools main mix outputs (usually output channels 1–2).
You can configure headphone output through the Driver Control Panel. See “Using the Driver Control Panel” on page 51.
Do not use the front panel headphone out­puts for anything but headphones. If you use a headphone distribution amp or cue system, use any of the six available Line Out channels on the back panel. See “Addi­tional Analog Outputs” on page 40.
Connecting a Sound System
The default monitor outputs on the back of the Mbox Pro, (Line outputs 1 and 2) support 1/4­inch plugs. These connections can be balanced, TRS (Tip, Ring, Sleeve) style connectors, or un­balanced connectors. To listen to your Pro Tools session, these outputs can be connected to any amplification system: powered speakers, a home stereo system, or an audio mixer.
Headphone jacks and controls on front of Mbox Pro
When connecting to a stereo system, connect the left channel (often the white plug) to Line Out 1, and the right channel (often the red plug) to Line Out 2.
Chapter 6: Making Studio Connections 39
Line Out connectors for monitors on Mbox Pro
Line Outputs 1–6
Home stereo systems often use RCA connec­tors. You can use an adaptor or a special ca­ble to convert from the TRS or TS connectors used by Mbox Pro to the RCA connectors on your home stereo.
To connect a sound system:
For stereo monitoring, connect Line out 1 and
2 to the inputs of your left and right speak­ers/monitors. You can hook up more than one set of stereo speakers and switch between them (Speaker A, B, C switching). See “Setup (Output Setup)” on page 59
Mbox Pro is capable of 5.1 control room monitoring complete with custom configu­ration and routing controls. For more infor­mation, see “Setup (Output Setup)” on page 59.
Line Output 1–6
Line Outputs 1–6 can be connected to any de­vice that has analog inputs. Use these six bal­anced 1/4-inch TRS outputs to feed analog de­vices such as headphone amps or cue systems for discrete headphone mixes, samplers, or a sec­ondary recorder.
There are other use for Line Outputs, such as:
• Stereo main monitors (Outputs 1–2)
• Stereo/Alt monitors (Outputs 3–4)
• Surround (Outputs 1–6)
To connect additional Mbox Pro outputs:
1 Using 1/4-inch TRS cables, connect any of the
Line Out (1–6) connectors on the back panel to the inputs of your external devices.
See the Pro Tools Reference Guide for infor- mation on signal routing, sends and bussing.
Additional Analog Outputs
Mbox Pro provides a total of four insert jacks (Inserts 1–4), for inserting external processing devices on input channels. (See “Insert Jacks” on page 37.) Insert jacks are for putting a hardware signal processor (like and EQ or compressor) be­tween the onboard mic preamp and the on­board analog to digital convertor.

Overview of Analog Inputs
There are a total of six channels of analog input. On the front, they are labelled 01, 02, 03, and 04, On the back, the label is Aux Inputs 5/6. (There are also two channels of digital input.)
Inputs channels on the front/back of Mbox Pro
Chapter 6: Making Studio Connections 41
Mic/DI 1 and Mic/DI 2
Each Input section (01, 02) on the front panel has a combination jack (Mic/DI) that provides an XLR and 1/4-inch input for Inputs 1 and 2. (If you plug in an XLR mic, it’s Mic; if you plug in a 1/4-inch it’s DI).

Connecting a Microphone

Mic Cables and Connectors
Use a microphone with an XLR connector to connect the microphone to the Mbox Pro.
Or, you can toggle the Front/rear input source switch to source Input channels 1–2 from the back panel Line inputs instead.
Mic Inputs
The Mic Inputs (03–04) section on the back panel provide two dedicated XLR connectors for Input channels 3 and 4.
Or, you can toggle the Mic/Line switch on the front panel for Input channels 3 and 4. When “out” the Mic input is active; when “in” the Line Input (3 or 4) is active for that channel.
Aux Inputs 5/6
Aux In connectors are provided for Line and Phono sources via RCA or 1/8-inch connectors.
You can keep something plugged into RCA jacks (5/L and 6/R) but as soon as a 1/8-inch is plugged in, it will defeat the RCAs. Whenever something is plugged into the 1/8-inch, that’s what Pro Tools will see.
5/L and 6/R For interfacing with a pair of RCA cables from mixers, CD or DVD players, or sim­ilar sources.
1/8-inch For a 1/8-inch stereo plug from iPod or similar sources.
The Mbox Pro can only supply power through a microphone cable with an XLR connector. If you are not sure about the phantom power re­quirements for your microphone, refer to your microphone’s documentation or contact the manufacturer.
XLR connector
Phantom Power
Some microphones require power to operate. This power, called phantom power, is supplied ei­ther by a battery in the microphone, or through an audio interface (such as Mbox Pro) that can supply power through the microphone cable.
Most condenser microphones (such as an M-Audio Solaris) require phantom power to op­erate. Dynamic microphones (such as a Shure SM57) do not require phantom power to oper­ate, but are not harmed by it.
Although phantom power can be used safely with most microphones, it is possible to damage some ribbon microphones with it. Always turn off phantom power and wait at least ten seconds before connecting a rib­bon microphone.

Connecting DJ Equipment
To use the Aux Inputs 5/6:
1 Plug your DJ mixer, DVD player, or similar
outputs into the Aux Input 5/6 inputs (L and R).
There is no RIA A preamp or grounding post on the Mbox Pro, so connecting a turntable is not recommended.
Connecting an MP3 player or having some­thing plugged in to the 1/8-inch mini port will defeat the RCA input signal.

Digital Input and Output

Mbox Pro provides two channels of S/PDIF digi­tal input and output on the back panel (via a breakout cable that you connect to the multi­pin port). This lets you record signals from digi­tal devices into Pro Tools, and send digital audio from Pro Tools to other digital devices.
Use 75 ohm RCA cables (the standard for digital audio) as other cables (such as home stereo cables) may have problems.
3 Connect the Mbox Pro S/PDIF Out to the
S/PDIF input of the external device.
4 Be sure to read the next section for important
information.
Using S/PDIF Input
In Pro Tools, you can record or listen to an ex­ternal digital device that is connected to Mbox Pro’s S/PDIF Input connector. Pro Tools must first be configured to enable the S/PDIF In­puts.
Refer to this section whenever you plan to use S/PDIF input on Mbox Pro.
The following requirement only applies to using S/PDIF input to record or monitor dig­ital signals through Pro Tools LE and Mbox Pro.
Word Clock, MIDI, and S/PDIF input on Mbox Pro
Mbox Pro Setup Guide46
Mbox Pro does not support external sync at
88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz sample rates.
To enable the S/PDIF inputs on Mbox Pro:
1 Make sure your have connected the external
digital device to the correct Mbox Pro S/PDIF connector (In and Out).
2 Make sure the external device is powered on,
Clock Source
that it is set to the correct sample rate, and that it is configured to provide S/PDIF clock (if rele­vant to your device).
3 Launch Pro Tools LE.
4 Choose Hardware > Setup.
5 Click the Clock Source pop-up menu and
choose “S/PDIF.”
Enabling S/PDIF Input in the Hardware Setup dialog
Once enabled in the Hardware Setup dialog, the S/PDIF inputs become active and will pass audio to Mbox Pro.
Setting the Clock Source to S/PDIF is the only way to utilize S/PDIF input. Doing so lets you re­cord or monitor up to eight discrete input chan­nels (six analog and two S/PDIF).
Selecting any other Clock Source (Internal, or Word Clock) disables S/PDIF input. S/PDIF output remains available.
If you need additional MIDI ports you can add a compatible MIDI interface. USB MIDI interfaces work effectively with Pro Tools systems on Win­dows or Mac. Serial MIDI interfaces are sup­ported on Windows systems only.
Only USB MIDI interfaces are compatible with Pro Tools systems for Mac OS X. Mo­dem-to-serial port adapters and serial MIDI devices are not supported.
To connect MIDI devices to Mbox Pro:
1 Using a breakout cable, connect it to the
Word Clock, MIDI, and S/PDIF input on the back panel of the Mbox Pro.
2 Connect the MIDI OUT of your MIDI device
or controller to the MIDI IN port on the break­out cable.
3 Connect the MIDI IN of your MIDI device or
controller to the MIDI OUT port on the break­out cable.

Word Clock

Mbox Pro provides Word Clock In and Out con­nectors on the back panel that let you synchro­nize, or “clock” Pro Tools LE and Mbox Pro to industry standard Word clock. Word clock is used to synchronize a wide range of devices such as non-linear video systems and other types of equipment typically found in professional audio facilities.

MIDI Connections

Two MIDI ports become available when you connect the provided breakout cable into the Word Clock, MIDI, and S/PDIF input on the back panel of the Mbox Pro. See “Word Clock, MIDI, S/PDIF Connector” on page 37.
With both Word clock input and output, your Mbox Pro-equipped Pro Tools LE system can act as Word clock “slave” or “master.”
Chapter 6: Making Studio Connections 47
Do not confuse Word clock and other forms of “clock reference” with time code and other forms of “positional reference.” For an overview of synchronization terminology and concepts, see the
Pro Tools Reference
guide.
2 Configure all external devices to slave to the
Word clock coming from Mbox Pro. (Be sure to verify sample rate settings, termination require­ments and other internal settings for the device; refer to the manufacturer’s documentation if you need more information on the particular re­quirements for your other equipment.)
Mbox Pro will synchronize to Word clock at
88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz sample rates.
To connect Word clock to Mbox Pro:
Using high-quality, 75 ohm BNC cables (not
included) connect the Mbox Pro Word Clock In and Out connectors to the appropriate ports on the other Word clock-capable devices in your studio.
Using Word Clock with Pro Tools LE
Pro Tools LE with Mbox Pro can act as Word clock master, or as a slave to Word clock sup­plied by an external device.
Pro Tools LE as Word Clock Master
Mbox Pro Word clock output is always active, letting Pro Tools supply Word clock to any con­nected devices that support standard Word clock.
3 Launch Pro Tools.
4 Choose Hardware > Setup.
5 Click the Clock Source pop-up menu and
choose Internal.
Pro Tools LE as Word Clock Slave
In order to slave Pro Tools to an external Word clock source, you must configure Word clock as the Pro Tools Clock source, as follows:
To configure Pro Tools LE with Mbox Pro as a Word clock slave:
1 Make sure all Word clock and audio connec-
tions are correct as described earlier in this sec­tion.
2 Make sure the external Word clock source is
powered on, and configured to output 1x Word clock. (Be sure to verify any required termina­tion; refer to the manufacturer’s documentation if you need more information on the particular requirements for your device.)
3 Launch Pro Tools.
To use Pro Tools LE as Word clock master:
1 Make sure all connections are correct between
Mbox Pro and your external devices.
Mbox Pro Setup Guide48
4 Choose Hardware > Setup.
5 Click the Clock Source pop-up menu and
choose Word Clock.
S/PDIF digital input is not available when the Pro Tools Clock source is set to Word clock or Internal. To use S/PDIF input, S/PDIF must be the Pro Tools Clock source. For more information, see “Digital Input and Output” on page 46.

Using a Footswitch

The footswitch connector on Mbox Pro lets you use a footswitch pedal to control either playback start/stop or recording punch in/out. Both QuickPunch audio punch-in and punch-out and MIDI punch-in and punch-out recording are supported.
The footswitch connector is designed specifi­cally for instantaneous (momentary) on/off pedals with a 1/4-inch TS connector. Continu­ous on/continuous off pedals can also be used, but may result in unexpected behavior.
To use a footswitch control:
1 Connect a footswitch to the footswitch con-
nector on the back panel of the Mbox Pro.
2 Launch Pro Tools.
3 Choose Setup > Hardware.
4 Select Record Punch In/Out or Playback

Using the Driver Control Panel

The Mbox Pro Driver Control Panel lets you configure settings for your audio interface for use with Pro Tools or other audio applications that support the CoreAudio Drivers (Mac) or ASIO Audio Drivers (Windows) standard.
Several features of Mbox Pro can be accessed di­rectly from the Mbox Pro front panel, such as in­put gain, phantom power, and output levels. But there are many additional parameters that cannot be accessed from the front panel. These additional features are available to you using the included Driver Control Panel application.
To open the Driver Control Panel:
On Mac, launch System Preferences (Apple
menu > System Preferences), then double-click Avid Mbox Pro. (You can also open the Driver Control Panel from the Applications menu.)

Layouts

The Layout drop-down menu lets you choose what information you would like the Driver Control Panel to show, and how you would like that information to be displayed. There are four layouts to select from:
Horizontal

Presets

The Preset view lets you load and save Mbox Pro Settings files, which contain all settings of the Mbox Pro Driver Control Panel. This is useful if you'd like to save various configurations so that you do not have to manually reconfigure your system ea ch time you wor k on a diff erent type of project.
For example, you could save the following pre­sets:
• A preset for live tracking, in stereo (low-la­tency/direct monitoring, and/or for dis­crete headphone mixes).
• A preset for mixing in stereo (alternate speakers, etc.).
• A preset for working in multi-channel/sur­round.

Additional Functions

Mbox Pro also features a variety of functions ac­cessible through pop-up menus located at the upper-right area of the Control Panel:
•Tuner
•Setup
• General Setup
• Output Setup
•Flow
•About
Tun er
The Tuner activates the tuner function of Mbox Pro. You can also access the tuner by pressing the front panel Mono and Dim buttons simultaneously. A tuner display will appear in the center of the Driver Control Panel, and the front panel input meters will function as tuning indicators as well.
When tuning from the front panel, use the in­put meters (LED ladders). They are red when out of tune and green when in tune.
Setup
Setup has two modes; “General Setup” and “Output Setup.” You can toggle between modes by clicking General Setup or Output Setup in the Setup pop-up menu.
General Setup is where you define the hardware settings of the Mbox Pro. For example, you can set buffer size, sample rate, and clock source. You can also define how Mbox Pro functions when it’s connected to a computer or when it’s in standalone mode (not connected to a com­puter). Think of General Setup as a quick way to customize Mbox Pro behavior.
Output Setup is where you define the prefer­ences of your monitoring environment. For ex­ample, you can configure up to three stereo hardware output pairs to function as “control room output pairs.” Then you can use Mbox Pro’s Speaker button (front panel) to cycle through the control room output pairs.
Setup (General Setup)
Setup pop-up menu (General Setup mode shown)
Mbox Pro User Guide54
The “General Setup” options are grouped in the following categories:
Hardware Settings
This section of the Control Panel provides pa­rameters you can set on your interface when it is connected to a computer using a FireWire cable (i.e., Hosted Mode).
Disable Host Control
This setting lets you rest control of the Driver Control Panel from Pro Tools. When you launch Pro Tools, it takes control of the Driver Control Panel's first stereo mixer. If you want to obtain full manual control of the Driver Control Panel, choose this option.
If you want to use the Low Latency Monitor­ing option in Pro Tools, this option must not be checked.
Clock Source
This setting determines the clock source to which Mbox Pro is synchronized.
Internal If you are using Mbox Pro by itself (i.e., without other digital devices or an external clock), select the Internal option for the interface to work properly
S/PDIF If you have connected a S/PDIF device to your Mbox Pro and would like to use that device as the master clock source, select the S/PDIF op­tion. This will make Mbox Pro clock to the exter­nal device’s clock.
Sample Rate
This drop-down menu sets the sample rate of Mbox Pro. Note that when using the interface with an ASIO or CoreAudio application, the sample rate can also be determined by your au­dio application. This parameter may not be ed­itable from within the Mbox Pro Control Panel if your audio application is running. In this case, any changes to the sample rate must be made through the audio application itself. If the appli­cation does not provide a way to set the sample rate, quit the application, then change the sam­ple rate through the Mbox Pro Control Panel.
In Windows Vista, when using the Mbox Pro WDM/MME (i.e., non-ASIO) drivers, the sample rate of the interface (and your audio software) is always determined by this drop-down menu. Your selection in this menu is the only item that will appear in your audio application. For example, if you select “44.1kHz” in this menu, your audio application’s control panel will only display “44.1kHz” and you will not be able to select any other rates from within the ap­plication.
When the sample rate is locked to an external digital clock source, the Mbox Pro’s LED is solid blue. When the sample rate is set and there is no digital clock source detected (or cannot lock to it for some reason), the LED will blink. (A message appears at the bottom of the Hardware Settings section stating that: “External clock not de­tected, Audio Streaming is Disabled.”).
Wor d Clo ck If you are transferring material into Pro Tools from an external digital device, or if you utilize a common house clock signal, you will need to synchronize Pro Tools to that digital device or common signal. Select the Word Clock option.
Appendix A: Using the Driver Control Panel 55
Buffer Size (Windows only)
Soft Button Settings
This menu sets the size of the input and output buffers on Mbox Pro.
Buffers are used to help keep audio hardware and software running smoothly by processing audio in groups of samples rather than one sam­ple at a time. Due to variations between com­puter hardware and software, it is impossible to recommend a single optimum setting for all sys­tems. It may be necessary to experiment with various settings until you find the best buffer size for your system.
The goal of setting a buffer size is to reduce it as much as possible without hearing any clicks, pops, or other glitches. If the buffer size is too small, the computer will not be able to make all the required audio calculations on time and you will hear pops, clicks, and stuttering in your au­dio streams. On the other hand, if the buffer size is set too high, your computer will process audio without incident, but your software will feel sluggish and unresponsive. See “Hardware Buf­fer Size” on page 18.
To find your system’s optimum buffer size set­ting, begin with a high setting and gradually re­duce the size until you begin to hear clicks, pops, or other audible glitches in your audio. Then, raise the buffer size setting until these glitches disappear. You may need to stop play­ing audio any time you change this setting and certain applications will require you to re­launch the program before the new buffer size settings become active.
This menu only appears on Windows sys­tems. Most Mac OS X applications allow to change the buffer size from within the au­dio application itself. Please see your audio application’s user guide to learn how to change this setting.
Press and Hold Duration
This pop-up menu gives you four choices of Press and Hold duration for all soft buttons on the front of the Mbox Pro. Choose between 250 msec, 500 msec, 750 msec, and 1 sec.
Use Dim LEDs for Button off State
Checking this option gives you a dim LED for all the soft buttons that are off (so you can still dis­cern the LED in the dark).
High-pass Filter Enable
There is a high-pass filter on the first four chan­nels. Let’s say you are recording an instrument that does not produce very low frequency sounds. You can enable the associated channel’s high-pass filter (check In 1, In 2, In 3, or In 4) to remove handling and low rumble from a vocal microphone.
Driver Control Panel Options
Hold Clipping Indicators until Clicked
The top section of the meters (or right section for horizontal meters) of the Driver Control Panel feature a red clipping indicator. When this option is selected, the clipping indicators will re­main lit until they are clicked.
Load Latency and Clock Settings from Settings Files
When this option is selected, the clock source and buffer settings are recalled when loading a setting file.
Mbox Pro User Guide56
Post-Fader Meters
Standalone Settings
When this option is selected, fader positions will affect the meters. Post-Fader Meters mean the meter indicate post-fader levels.
Pre-Fader Meters
When this option is selected, the meters display the level of a signal before it passes the fader. This allows signal levels to be displayed regard­less of the fader positions within the stereo mix (in other words, a fader can be all the way down and no sound will be heard from the mixer’s output, but you can still see if there is any activ­ity on that input).
FX Sends Mode
Pre-Fader FX Sends
When Pre-Fader FX Sends is selected, the full au­dio signal will be sent to the FX Sends, regardless of the position of the Channel Faders of stereo mix 1–2.
Post-Fader (Mix 1/2) FX Sends
When Post-Fader (Mix 1/2) is selected, the audio signal level being sent to the FX Sends will be af­fected by the position of the Channel Faders of Stereo Mix 1.
Standalone settings affect the setting of the Mbox Pro when it's in standalone mode with no host computer connected.
When you set up your standalone settings, you must be connected to the computer.
The interface can function in the following two modes:
Hosted Operation If there is a FireWire connec­tion to the computer when the Mbox Pro is first powered on, then it boots into hosted mode.
Standalone Operation If there is no FireWire con­nection to the computer when the Mbox Pro is first powered on, then it boots into standalone mode.
When you are in standalone mode, the follow­ing functions can be adjusted:
•Clock source
•Sample rate
•Mode
Clock Source
Clock source and sample rate settings work in the same manner as above, it defines what the clock source will be; internal, S/PDIF, or word clock.
The clock source can be switched from the front panel when in standalone, using the Multi but­ton.
The LED button will either be off/on/pulsing to indicate which clock source is currently as­signed.
• If the LED if off, the clock source is internal.
• If the LED is on, the clock source is word clock
• If the LED is pulsing, clock source is S/PDIF
Appendix A: Using the Driver Control Panel 57
Sample Rate
This setting assigns the sample rate when it's set to internal clock source in standalone mode.
Mode
The Mbox Pro can be in the following three types of sub-standalone modes:
AD/DA Converter When in AD/DA mode, analog inputs 1 and 2 are routed to S/PDIF outputs left and right and S/PDIF inputs left and right are routed to analog outputs 1 and 2.
Preamp When in Preamp mode, analog input 1 is sent to analog output 1 and S/PDIF left. Ana­log input 2 is sent to analog output 2 and S/PDIF Right. Analog inputs 3–6 are sent to analog out­puts 3–6.
Mixer When in Mixer mode, all analog and dig­ital inputs are summed and routed to analog outputs 1-2 are mirrored to S/PDIF outputs left and right.
Changing Sub-standalone Modes
Once you are in standalone mode you can tell which of the three sub-standalone modes the Mbox Pro is in and change them using the Speaker source select switch (pushing the Speaker button cycles through them all).
The button displays the following colors for each mode:
• Green in AD/DA Converter Mode
• Red in Preamp mode
• Amber in Mixer mode
Mbox Pro User Guide58
Setup (Output Setup)
Output Setup lets you set up stereo and sur­round monitoring options/settings.
Stereo Monitor Configuration
You can configure up to three stereo hardware output pairs to function as control room moni­tor pairs. Pressing the speaker button on the front panel of the hardware cycles through the control room output pairs. This is useful for A/B-ing your mix between different studio mon­itors.
For example, if you check “Master Volume” for the first three output pairs, then the master vol­ume would control all of them at once. This is useful if you are mixing in surround.
Setup pop-up menu (Output Setup mode shown)
The Output Setup options are grouped in the fol­lowing categories:

Control Room Assignment
This drop-down menu assigns a hardware out­put (1–2 or 3–4 or 5–6) as a control room output. You have four choices when setting up your control room monitor pairs: Choose between the following options:
•None
• Speakers A (Green LED)
• Speakers B (Red LED)
•Speakers C (Amber LED)
Let’s say that outputs 1–2 are set up to be Speak- ers A, outputs 3–4 are set up to be Speakers B, and outputs 5–6 are set up to be Speakers C. Pressing Mbox Pro’s Speaker button lets you switch between the three pairs of speakers. (Only one control room output pair is active at any time in Stereo mode.)
Left Trim This knob trims the level of the Left (odd numbered) output.
Right Trim This knob trims the level of the Right (even numbered) output.
Hardware Outputs 7–8
These outputs are not assignable as control room outputs.
Headphones 1 This lets you label the headphone out for Headphone output A.
Headphones 2 This lets you label the headphone out for Headphone output B.
Close Select this button to closes the dialog box.
Flow
Clicking the Flow pop-up menu opens a display showing the signal flow from the inputs to the outputs of Mbox Pro. This is a useful reference for understanding the path of an audio signal flowing through Mbox Pro.
Master Vol.
Checking this option lets you choose which out­put pairs are controlled by Mbox Pro’s master volume knob.
If you check “Master Volume” for the first three output pairs, then the master volume knob con­trols all of them at once. (If one output pair is designated as a control room speaker pair, this checkbox is automatically checked and cannot be unchecked.)

Appendix A: Using the Driver Control Panel 61
The available output pair audio sources can be divided into two categories:
Stereo Mixes
A stereo mix lets you set up a custom stereo mix, setting the desired level for each hardware input and software return that is fed to the hardware output pair. See the Stereo Mix section below for details.
Direct Routes
A direct route means that the chosen signal is passed directly to the hardware output pair. For example, if the source for output pair 1–2 were “Hardware Inputs 1–2,” then the signal coming into hardware inputs 1–2 of the Mbox Pro would be fed directly to hardware outputs 1–2. Similarly, if the source were “Software Returns 1–2,” the signal fed from an audio host software returns 1–2 would be fed directly to hardware outputs 1–2.
Notes:
• The source of the currently selected tab is displayed below the output pair select view. See “Setup (Output Setup)” on page 59.
• For Stereo Mix sources, a traditional mixer view is displayed. See “Stereo Mixes” on page 63.
• For direct route sources, a view with meters is displayed, and the input source and out­put destination are highlighted.
• You can drag and drop the tabs to reorder them if you want.
Notes on output pairs that are designated as control room outputs:
• If an output pair is a designated control room output (see Setup Drawer section above), a speaker icon will appear in the upper right corner of the tab. Click the speaker icon, or double click the tab, to make the associated output pair the active control room speaker pair.
• Control room output pairs must have ste­reo mixes as their source. This is enforced automatically by the software.
• In most cases, you will want to use the same stereo mixer (for example, Stereo Mix 1) for all designated control room out­put pairs. This is not enforced by the soft­ware, because there are cases in which varying sources for control room output pairs would be desirable.
Mbox Pro User Guide62

Stereo Mixes

These 16-input, 2-output mixes allow you to cre­ate up to six stereo mixes when running at a sample rate at or below 96 kHz, and up to two stereo mixes when running at a sample rate above 96 kHz.
This lets you set up near-zero latency cue mixes in which the performers hear a “customized” mix while recording.
It is important to note that any changes made to the stereo mix will only affect what is audible from the mixer’s outputs—the stereo mix does not affect the signals that are sent to Pro Tools for recording. For example, if you are recording a vocalist and he/she tells you to turn up the vo­cal track so they can hear themselves better, you can increase the vocalist’s microphone channel in the stereo mix. This will make the vocal part louder in the vocalist’s headphones, but it will still be recorded into Pro Tools at the volume de­termined by the front panel Gain Adjustment Knob.
The stereo mix is set up like a standard mixing console: There are 16 input channels, each with its own volume fader, pan and aux send knobs, solo, and mute buttons, as well as a master out­put section with its own pair of faders and m ute buttons.
A pair of channels can be linked together by clicking the link icon between the two channels. Linking channels lets you adjust mute, solo, and fader settings simultaneously by modifying pa­rameters on either one of the linked channels. However, linking two channels will not have any effect on their Pan controls, which are al­ways made on a per-channel basis.
The stereo mix features multi-segment meters to show input channel levels (directly above each channel) and main mixer output levels (at the top right of the mixer). The pre/post fader me­tering operation can be set from the Setup Tab of the Control Panel. The clip indicators can be set to “stick” by choosing Hold Clipping Indicators until Clicked in the Setup pop-up menu, and reset by clicking on the clip indicator itself.
Setting or adjusting the stereo mix will not af­fect the signal that is recorded into Pro Tools. For example, you’ll still be able to record a chan­nel while its corresponding stereo mix channel is muted. You won’t hear the part through the stereo mix as it is being recorded, but it will still record into Pro Tools and play back properly.

Software Returns
The Software Returns section is where the audio coming back from Pro Tools (or other audio ap­plication) is monitored. Software Returns 1 and 2 will be the default stereo output from Pro Tools.
Pan
Links buttons
Link
The Pan knobs control the position of a chan­nel’s audio signal in the stereo image of the ste­reo mix (double-click the knob to return pan to center).
Solo
Each Solo button lets audio be monitored for the channel of which it is a part, while simultane­ously muting all other Hardware Input channels and Software Returns (except for those that also have their Solo buttons activated).
Mute
The Mute buttons are used to individually turn off audio monitoring for each channel in the stereo mix.
Channel Faders
The Channel Faders control the monitoring vol­ume level of each channel in the stereo mix.
Channel Labels
The Link buttons connect stereo pairs of knobs or faders (and also links the corresponding FX Send knobs), so that adjusting either channel (left/right) adjusts the other side identically.
Pan controls are unaffected by linking two channels.
Hardware Input FX Sends
FX Sends are shared by all Stereo Mixes, unless “Post-Fader Stereo Mix 1” is chosen in the Setup pop-up menu.
Software Return FX Sends
FX Sends are shared by all Stereo Mixes, unless “Post-Fader Stereo Mix 1” is chosen in the Setup pop-up menu.
By default, the Channel Labels show the input name of each channel (1–8), except for the Mas­ter fader pair (which is labeled L/R by default).
Clicking on a Channel Label gives you a cursor, allowing you to type in your own custom chan­nel name (such as “guitar,” “vocals,” etc.).
The Channel Labels also display the signal level (in dB) while a fader is being adjusted.

Effect
The Effe ct drop-down menu is used t o se lect the effect to be applied to the Hardware Inputs and/or Software Returns (effects are not avail­able if the sample rate is > 96 kHz). There are five available reverb types: Three room reverbs and two hall reverbs, delay, and echo. These effects can be customized by using the following three controls:
Duration This knob controls decay time (for the reverbs) or delay time (for delay and echo).
Feedback This knob controls the number of re­peats for the delay and echo effects. It does not affect the reverbs.
Volume This knob controls the effects output level being sent to the FX Returns
The Master section lets you control the main mixer output. This output can be routed to any hardware output. Each Stereo Mix includes a master section with several controls:
Master section of the Driver Control Panel
Master Fader Adjusts the overall level of the ste­reo mix.

Hard Drive Configuration and Maintenance

It is recommended that you start with a newly formatted external or secondary internal audio drive. You should also periodically defragment your audio drive to ensure continued system performance.

Supported Drive Formats and Drive Types

Drive Formats
Always back up any important data on your drive before formatting it, as it will erase all data on the drive.

Avoid Recording to the System Drive

Recording to your system drive is not recom­mended. Recording and playback on a system drive may result in lower track counts or fewer plug-ins.
Mac Mac systems should use drives formatted with HFS+ or HFS file system only.
HFS drives are supported as Transfer drives only.
Windows Windows systems should use drives formatted as NTFS only.
Windows systems can also support Mac drives formatted with HFS+ system (also commonly referred to as Mac OS Extended). Refer to the Pro Tools Reference Guide for more information (Help > Pro Tools Refer­ence Guide).
Hard drive performance depends on factors in­cluding system configuration, number of tracks, session sample rate, density of edits, and the use of crossfades and other processes such as Beat Detective in a session.
For complete hard drive requirements, visit our website (www.avid.com).
Appendix E: Hard Drive Configuration and Maintenance 81
FireWire Hard Drives
Avid recommends qualified FireWire drives and (on Windows systems) a qualified FireWire host adapter.
For complete information on track count and the supported number and configuration of FireWire drives, visit our website (www.avid.com).
ATA/SATA Hard Drives
A qualified internal ATA/SATA drive may be used as a dedicated audio drive.
2 Click the Erase tab.
For complete information on track count with internal drives, refer to our website (www.avid.com).
SCSI Hard Drives
Avid recommends qualified SCSI hard drives and a qualified SCSI host bus adapter (HBA) card or (on Windows systems) a qualified built-in SCSI HBA connector on the motherboard.
For complete information on track count and the supported number and configuration of SCSI drives, visit our website (www.avid.com).

Formatting an Audio Drive

Formatting Mac Audio Drives
For optimum performance, audio drives should be formatted as Mac OS Extended (Journaled).
To format an audio drive:
1 Launch the Disk Utility application, located in
Macintosh HD/Applications/Utilities.
Disk Utility (Mac OS X)
3 Select the drive you want to initialize in the
column on the left side of the window.
4 Choose the Mac OS Extended (Journaled) for-
mat.
Do not choose the “Case-Sensitive” format option. Pro Tools will not operate properly with case-sensitive formatted drives.
5 Type a name for the new volume.
6 If you plan to connect the drive to a Mac OS 9
computer, select Install Mac OS 9 Drivers.
7 Click Erase.
The drive appears on the Desktop with the new volume name.
Formatting Windows Audio Drives
For optimal performance, audio drives should be formatted as NTFS.
Pro Tools only supports Basic drive types. Do not convert the drive to a Dynamic type.
Mbox Pro User Guide82
To format an audio drive (Windows 7, Windows Vista, and Windows XP):
1 Right-click Computer (Windows 7,
Windows Vista) or My Computer (Windows XP) and choose Manage.
2 Under Storage, choose Disk Management.
Disk Management window (Windows XP)
• In the New Partition Wizard window, click Next.
• When prompted, select the partition type.
Avid recommends using Primary partitions, instead of Extended partitions.
• Follow the on-screen instructions to select a partition size and other partition settings.
• When prompted, choose a file system. For optimum performance, audio drives should be formatted as NTFS.
• Select Perform a quick format.
•Make sure Enable file and folder compression is not selected.
• Set the Allocation unit size to Default.
• Click OK.
3 If the volume is “Healthy,” do the following:
Healthy volumes are volumes that have pre­viously been partitioned and formatted.
• In the Disk Management window, right­click the hard drive you will use for audio and choose Format.
• In the Format window, name the volume.
• Choose a file system. For optimum perfor­mance, audio drives should be formatted as NTFS.
• Select Perform a quick format.
•Make sure Enable file and folder compression is not selected.
• Set the Allocation unit size to Default.
• Click OK.
4 If the volume is “Unallocated,” do the follow-
ing:
• In the Disk Management window, Right­click the hard drive you will use for audio and choose New Partition.

Partitioning Drives

Partitioning creates a logical volume or volumes on a physical drive, almost as if you were creat­ing virtual hard drives. Partitions can then be formatted with the appropriate file system (NTFS for Windows, HFS+ for Mac).
Mac OS allows drives larger than 4096 MB to be seen as whole volumes. Drives must be initialized with a disk utility that recog­nizes the 2 terabyte limit. Single Pro Tools audio files cannot exceed 3.4 GB in size.
Windows XP allows drives formatted with the NTFS file system to be seen as whole volumes. Single Pro Tools audio files can­not exceed 3.4 GB in size.
Appendix E: Hard Drive Configuration and Maintenance 83
Seek Times on Partitioned Drives
Seek times are actually faster on partitioned drives (assuming that reads and writes are per­formed on a single partition), since the heads only have to seek within the partition boundar­ies, rather than the whole capacity of the drive.
Smaller partitions perform faster than larger par­titions, but this comes at the expense of contig­uous storage space. When you partition a drive, you will need to find the compromise that best suits your performance and storage require­ments.
Avoid distributing audio files within a ses­sion over different partitions on the same drive since this will adversely affect drive performance.

Defragmenting an Audio Drive

Mac Systems
When working with larger files (such as video), you can limit fragmentation by backing up your important files to another disk, erasing the files from the original hard disk, then copying the files back, instead of doing a defragmentation.
Window Systems
In multitrack recording, audio tracks are written in discrete files, spaced evenly across the disk. While fragmentation of individual files may be zero, the tracks may be far enough apart that playback will still be very seek-intensive. Also, the remaining free space on the disk will be dis­contiguous, increasing the likelihood of file fragmentation on subsequent record passes.
Increased fragmentation increases the chance of disk errors, which can interfere with playback of audio, and result in performance errors.
On Windows, to avoid fragmentation, format drives with higher cluster sizes (such as 32K).
Optimizing (Defragmenting) Drives
To prevent fragmentation, you can optimize your drive, which rearranges your files into a contiguous format. Most optimizing software lets you run a check on a drive to find out the percentage of fragmentation. If your drive shows moderate to heavy fragmentation, you should consider optimizing it.
If you use your system for intensive editing, or if you frequently delete audio or fade files from your hard drive, you may need to optimize your drives on a weekly basis, or even every few days, since it doesn’t take long for even a large hard drive to become fragmented.
Periodically defragment audio drives to maintain system performance.
For maximum recording and playback effi­ciency, data should be written to your hard drive in a contiguous fashion—minimizing the seek requirements to play back the data. Unfor­tunately, your computer can’t always store the sound files in this way and must write to disk wherever it can find space.
Mbox Pro User Guide84
Backing Up Data Before Optimizing
Since your files will be rewritten by the optimi­zation process, always make a backup copy of the data on your hard drive before you optimize it. You should also use a hard drive utility to find and repair any problems before optimizing data or re-initializing your drives. If there is any dam­age to your hard drive's directories prior to opti­mizing, serious data loss may result.
Defragmenting Windows Audio Drives
To defragment an audio drive (Windows 7 and Windows Vista):
1 Click Start.
2 Type “disk defragmenter” in the search field at
the bottom. “Disk Defragmenter” should appear at the top of the search results.
3 Click the Disk Defragmenter.
4 Click the Defragment disk button (Windows 7)
or the Defragment now button (Windows Vista). Follow the on-screen instructions.
5 When defragmenting is complete, close the
Disk Defragmenter window.
In Windows 7 you can Ctrl-Click on the drive names to select multiple drives to de­fragment, and once more than one drive is selected, the button changes to “Defrag­ment disks.”
The “Defragment Now” (Vista only) com­mand defragments all your hard drives. This can take a lot of time, especially on systems with multiple drives.
Advanced users can use the command line tool Defrag.exe to defragment individual drives. See your Windows Vista documen­tation for more information.
5 When defragmenting is complete, close the
Computer Management window.

Using Mac Drives on Windows Systems

Pro Tools for Windows lets you record and play back sessions directly from a Mac-formatted (HFS+) drive connected to a Windows system. This functionality requires that all Mac session and audio files be stored on Mac-formatted drives.
During Pro Tools installation, make sure to se­lect the Mac HFS+ Disk Support option. This op­tion lets your Pro Tools system read, write, re­cord, and play back using Mac-formatted HFS+ disks.
For information on sharing sessions be­tween Mac and Windows systems, see the Pro Tools Reference Guide (Help > Pro Tools Reference Guide).
Formatting and Maintaining HFS+ Drives
To format and partition any drives as HFS+, con­nect the drives to a Mac computer and use the Apple OS X Disk Utility to format the drives as Mac OS Extended (Journaled).
To defragment an audio drive (Windows XP):
1 Right-click My Computer and choose Manage.
2 Under Storage, choose Disk Defragmenter.
3 In the Disk Defragmenter window, choose the
drive you want to defragment
4 Click the Defragment button and follow the
on-screen instructions.

Troubleshooting

Backing Up Your Work

It is highly recommended that you back up your work on a regular basis, and especially before making changes to your system configuration.
Backing Up Your Session Data
Back up your session and audio data frequently. There are a variety of media that are suited to back up projects of various sizes, from auto­mated tape backup systems to high-capacity op­tical drives, or to CD burners.
The best way to back up an entire session is to use the Save Copy In command. This command lets you save the session file and all of its associ­ated files to a new location.
You can also use the Auto Save Backup fea­ture (in the Operation Preferences page) to have Pro Tools automatically save backups of the session file while you work.
Backing Up Your System Configuration
After configuring your system and Pro Tools, you should save an image of your system drive using a backup utility such as Norton Ghost (Windows) or Bombich Carbon Copy Cloner (Mac). By doing this, you can quickly restore your system configuration and settings if you encounter any problems.

Common Issues
