A. Connecting Your Studio
Your studio equipment needs will vary depending on which Pro Tools LE system you’re running—Digi 002, Digi 002 Rack, Mbox, Mbox 2, or Mbox 2 Pro—and the type of audio source, external hardware, and monitor system you want to connect it to.
If you already have a studio full of great-sounding peripheral hardware, don’t worry: You can connect all types of external hardware to Pro Tools LE systems. How many pieces of external hardware you can connect at one time, however, depends upon which Pro Tools LE system you’re using.
Connecting Your Studio to the Digi 002, Digi 002 Rack, Mbox, Mbox 2, or Mbox 2 Pro
The minimum studio setup needed to record with Digi 002, Digi 002 Rack, Mbox, Mbox 2, and Mbox 2 Pro is a mic and mic cable (or instrument and instrument cable), and a pair of headphones. Figures A.1–A.4 show basic studio setups for Digi 002, Digi 002 Rack, Mbox, Mbox 2, and Mbox 2 Pro systems, respectively.

With eight channels of analog I/O (including four balanced mic preamps with individual high pass filters) and 24-bit, 96 kHz A/D input signal conversion, Digi 002 and Digi 002 Rack give you the best audio quality and most input versatility of the LE systems.
Digi 002 and Digi 002 Rack also give you eight channels of optical I/O, two channels of S/PDIF digital I/O, and two alternate analog inputs (RCA plugs) for connecting an external sound source, such as a CD player or tape deck.
The original Mbox has far fewer I/O options than the Digi 002. You can, however, connect external hardware using the system’s two channels of analog I/O and two channels of S/PDIF digital I/O. Mbox also provides two 1/4-inch line inserts, which let you add external hardware effects during recording.
Mbox 2 and Mbox 2 Pro offer significantly more I/O options than the original Mbox.
The USB-based Mbox 2 audio interface includes two mic preamps (XLR), two 1/4-inch TRS inputs, and two DI inputs (1/4-inch TS). It also gives you two channels of S/DIF Digital I/O, two channel 1/4 (TRS) monitor outputs, as well as one MIDI In and one MIDI Out port.
The FireWire-based Mbox 2 Pro provides the same I/O features as the Mbox 2, with some key upgrades. The interface includes two built-in mic preamps (XLR-1/4-inch TRS combo jacks), which can record at sample rates up to 96 kHz. In addition, Mbox 2 Pro includes a two-channel auxiliary input section with both 1/4-inch TRS (balanced) and RCA stereo plug (unbalanced) inputs, It has four 1/4-inch TRS analog outputs, two channels of S/PDIF digital I/O, two channel 1/4 (TRS) monitor outputs, one MIDI In and one MIDI Out port, and Word Clock I/O.

Connecting Audio Sources to Mbox
Mbox provides two combination Mic/Line preamps. These Mic/Line preamp inputs accept either XLR (3-pin) or 1/4-inch TRS cables. Mbox also provides two channels of S/PDIF digital I/O.
The front panel of the Mbox (Figure A.8) has the following features:
• 48V LED: When lit, the 48V LED indicates that 48V phantom power is available at the Mic/Line input.
• Source selector: The Source selectors let you switch between three input level options for the Mbox’s Mic/Line inputs: Mic (microphone), Line, and Inst (Instrument).
• Gain controls: Gain controls let you adjust the input level of the Mic/Line inputs.
• Peak LEDs: Peak LEDs light up just below analog clipping levels. This warns you that the input signal may be approaching clipping.
• USB LED: The USB LED indicates that the USB port is active, and audio can pass in or out of the system.
• S/PDIF LED: The S/PDIF LED indicates that channels 1 and 2 are set to receive digital input (rather than analog).
• Mix (Ratio) control: The Mix (ratio) control lets you monitor an adjustable blend of live input signal (with zero latency) and audio playback from disk. To hear the input signal only, turn the Mix knob hard left to Input. To hear Pro Tools output only, turn the knob hard right to Playback.
• Mono switch: The Mono switch lets you hear live input signals in mono. You can use this switch to check for stereo phase cancellations. (Typically, out-of-phase tracks sound hollow and lacking in low frequencies.)
• Headphone gain: Headphone gain controls the output level of the headphones on both the front and back panels.
• Headphone output (front panel): The front panel headphone output is a 1/8-inch stereo mini connector. (Inserting a 1/4-inch TRS connector into the rear panel headphone disables the 1/8-inch headphone output on the front panel.)

For more information on connecting analog and digital hardware to Mbox 2 or Mbox 2 Pro, see the Getting Started Guide that came with your system.
Connecting Audio Monitors
If you’re using Digi 002, Digi 002 Rack, Mbox 2, or Mbox 2 Pro, the easiest way to monitor audio is with headphones plugged into the jack on the front of their respective interfaces. Original Mbox users have two headphone options: a 1/8-inch stereo mini connector on the front panel and a 1/4-inch TRS connector on the rear panel. Mbox 2 and Mbox 2 Pro users have to use the 1/4-inch headphone jacks provided.
While monitoring over headphones is useful for hearing accurate stereo mixes, whenever possible, it’s best to monitor your audio through a set of speakers as well. Speakers give you a more accurate representation of how most listeners will experience your mixes—in a 3-dimensional space, over an average home stereo system.
Listening to headphones at even moderate volumes for prolonged periods can cause hearing damage and permanent ringing in the ears, or tinnitus. Always make sure your headphone volume is turned down before listening, and then turn the volume up slowly and carefully!
To connect monitor speakers to the Digi 002 or Digi 002 Rack
1. Connect 1/4-inch TRS cables to the left and right monitor outputs on the back of the Digi 002 or Digi 002 Rack.
2. Connect the 1/4-inch TRS cables to left and right inputs on your power amp, mixer, self-powered speakers, or home stereo.
Most home stereo systems use RCA connectors and will require an adapter.
To connect monitor speakers to the Mbox, Mbox 2, and Mbox 2 Pro
1. Connect 1/4-inch cables to the left and right monitor (or line) outputs on the back panel of the interface.
2. Connect the 1/4-inch cables to the corresponding left and right inputs on your power amp, mixer, self-powered speakers or home stereo.
Most home stereo systems use RCA connectors and will require an adapter.
Tip• During the recording and mixing process, it’s useful to listen over as many different sets of speakers as possible. Most studios have small, medium-size, and large monitor speakers (some even have ultra-tiny and extra-large speakers), which can help you gain perspective on the frequency balance and overall sound quality of your mixes.
Connecting MIDI Devices
The Digi 002 and Mbox 2 systems’ built-in MIDI ports make it easy to connect MIDI devices (such as MIDI keyboard controllers, MIDI instruments, and sound modules). A MIDI driver for these ports is installed with Pro Tools LE and recognized by Midi Studio Setup (Windows) and Audio MIDI Setup (Macintosh).
Original Mbox users will need a third-party MIDI interface to record MIDI into Pro Tools LE.
For information on recording and editing MIDI in Pro Tools 7 LE, see Chapter 18: Recording MIDI and Chapter 19: Editing MIDI.
To connect a MIDI device to the Digi 002 or Digi 002 Rack
1. Connect a standard five-pin MIDI cable from the MIDI Out port on your MIDI device to the MIDI In port on the Digi 002 or Digi 002 Rack’s back panel.
2. Connect a standard five-pin MIDI cable from either of the two MIDI Out ports on the Digi 002 or Digi 002 Rack’s back panel to the MIDI In port on your MIDI device.
3. Connect the audio outputs of your device to an available audio input on the Digi 002 or Digi 002 Rack’s back panel.
To connect a MIDI device to Mbox 2 or Mbox 2 Pro

2. Connect a standard five-pin MIDI cable from the MIDI output on the Mbox 2 or Mbox 2 Pro box to the MIDI input on your MIDI device.
Connecting External Hardware Effects
Pro Tools lets you route both analog and digital audio signals to external hardware effects (such as equalizers, compressors, reverbs, and delays). Using the Digi 002, Digi 002 Rack, Mbox 2, or Mbox 2 Pro’s 1/4-inch analog inputs and outputs, or S/PDIF digital inputs and outputs, you can run several external hardware effects with your system.
The original Mbox has two 1/4-inch TRS inserts, which let you place effects into the path of analog audio entering Source 1 and Source 2 Mic/Line inputs. The inserted effect is added to the incoming signal before it’s converted into digital audio. These inserts are useful for adding effects such as equalizers and compressors to tracks during recording.
Connecting external analog hardware effects
To connect an external analog hardware effect to the Digi 002 or Digi 002 Rack
1. Connect a mono (single) or stereo (pair) output from analog outputs 5–8 to the corresponding inputs of the hardware effect.
2. Connect the outputs of the hardware effect to the corresponding analog inputs on the Digi 002 or Digi 002 Rack’s back panel.
To insert an external hardware effect on the Mbox’s input signal path
1. You’ll need a TRS Y cable (a TRS connector that splits into two unbalanced connectors).
2. Connect the unbalanced connector that corresponds to Tip to the input port of the hardware device.
3. Connect the unbalanced connector that corresponds to Ring to the output port of the hardware device.
4. Insert the TRS connector into the desired insert port on the Mbox.
