Gain Controls/–20dB Pad
These knobs adjust the input gain levels of the
Mic/Line inputs. Turn the knob clockwise to increase gain, and counter-clockwise to decrease gain.
If your input signal is too hot even with the
Gain knob at a low setting, pull the Gain knob out to engage a “pad” that attenuates the signal by 20 dB.
About Phantom Power
Dynamic
microphones (such as Shure SM57s or
M-Audio Aries) do not require phantom power to operate, but are not harmed by it. Most
condenser
microphones (like an M-Audio Solaris)
do
require phantom power to operate.
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.
Signal/Clip LEDs
These LEDs illuminate green in the presence of audio signal, and illuminate red if the input signal has “clipped” (overloaded) the input of the
Mbox. Clipping the input can result in audible distortion.
Soft-Limit Buttons
These buttons activate the Soft-Limit function, applying a smooth, overdriven tape-type limiting to strong input signals on the Instrument,
Mic, or Line inputs.
When using phantom power, the Mbox maximum current per microphone is 4 mA.
If you are not sure about the phantom power requirements for your microphone, consult your microphone’s documentation or contact the manufacturer.
Monitor Level
The Monitor Level knob adjusts the output level of the Monitor Output ports.
+48V Switch and LED (Phantom
Power)
The +48V switch toggles phantom power on/off for all mic input channels. The LED, when lit, indicates that 48V phantom power is active on the XLR Mic inputs.
Dim Button and LED
The Dim Button reduces by 30 dB the output volume from both the Monitor Outputs and the
Headphone Output. When engaged, the Dim
LED lights.
Mono Button
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. When engaged, the Mono
LED lights.

Mbox User Guide
Checking Phase Relationships
The Mono switch can also be used for a quick check of the phase relationship between
Source 1 and Source 2 inputs.
Guitar Tuner Function
When the Dim Button and the Mono Button are pushed at the same time, the Guitar Tuner function is activated. The Dim and Mono LEDs flash between off and on to indicate tuner mode is active. When a string is played on a guitar plugged into an Instrument Input, the Input 1 Signal/Clip LED is illuminated red if tuning is too low, off when tuning is too high, and green when tuning is correct. The Input 2 Signal/Clip
LED is illuminated red if tuning is too high, off when tuning is too low, and green when tuning is correct. The Tuner interface is displayed in the
Software Control panel if the Software Control
Panel is open.
Multi Button
(Pro Tools Only)
The Multi Button can be assigned to execute several functions in Pro Tools, including Add Track,
Start/Stop Record, Tap Tempo, Toggle Marker
Locations, and Save Session. See Chapter 5, “Using the Multi Button (Pro Tools Only).”
USB LED
The USB LED indicates that the Mbox is receiving power from its USB connection. Once the
USB light is on, audio can pass in or out of the system.
The USB LED is a power LED, which is also indicates when the unit is powered in stand-alone mode. In this mode you can connect a USB cable but that cable is connected to a wall outlet instead of a computer (similar to an iPod or iPhone).
Front Panel Headphone Output
Use the Headphone Output to connect stereo headphones with a 1/4-inch stereo connector.
The headphone outputs mirror the signal sent to the Monitor Outputs.
Headphone Volume
The Headphone Volume knob adjusts the output level of the Headphone port. This output is independent of the Monitor Level knob.

This standard USB connector is used to connect a USB 2.0 port on your computer to the Mbox.
One standard USB cable is included with your system. (It is also used to power the unit in stand-alone mode.)
In use, the S/PDIF input and output channels are available in addition to the four channels of analog audio I/O.
Mic/Line Input 2 is at the far left (when looking at the back panel), and Mic/Line Input 1 is to its right. The back panel inputs for Mic/Line Input
1 and Mic/Line Input 2 are located such that they are directly in line with their associated input controls on the front panel. This lets you locate input jacks more easily when viewing from the front of the unit.
Monitor Outputs
These outputs support balanced TRS, or unbalanced TS, 1/4-inch connections. To monitor your mix, connect these outputs to a mixing board, directly to a monitoring system such as a stereo power amp, or another stereo destination.
Mic/Line Inputs
Each analog source input channel provides combination XLR/TRS on the rear panel. These balanced/unbalanced analog audio inputs support the following input levels:
• Mic (microphone) for XLR inputs
• Line (TRS) for line level signals on TRS or TS inputs
On the front panel, the input signal is adjusted by the Gain control for each channel and the source (rear panel Mic/Line, or front panel Instrument) is chosen using the Source selectors.

Mbox User Guide
S/PDIF Digital I/O
The S/PDIF in and out ports are unbalanced twoconductor phono (RCA) connectors that utilize a full 24-bit, two-channel digital data stream.
The Sony/Philips Digital Interface Format
(S/PDIF) is used in many professional and consumer CD recorders and DAT recorders. To avoid RF interference, use 75-ohm coaxial cable for S/PDIF transfers and keep the cable length to a maximum of 10 meters.
MIDI I/O
The MIDI In and MIDI Out ports are standard
5-pin MIDI ports, each providing 16 channels of
MIDI input and output.

Additional Functions
Mbox also features a variety of functions accessible through pop-up menus located at the upper-right area of the Control Panel:
• Tuner
• Setup
• Flow
• About
Setup
Setup is where you define the hardware settings of the Mbox. For example, you can set buffer size, sample rate, and clock source. Think of
Setup as a quick way to customize Mbox behavior.
Tuner
The Tuner activates the tuner function of Mbox.
You can also access the tuner by pressing the front panel Mono and Dim buttons simultaneously. A tuner display appears in the center of the Driver Control Panel, and the front panel input meters 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 pop-up menu
In the Setup window, the options are grouped in the following categories:
Hardware Settings
The parameters in this section of the Control
Panel govern the operation of the interface when it is connected to a computer using a USB cable (Hosted Mode).
This section of the Control Panel provides parameters you can set on your interface when it is connected to a computer using a UBS cable.
24
Mbox User Guide
Disable Host Control
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 of Pro Tools, this option must not be checked.
Clock Source
This setting determines the clock source to which Mbox is synchronized.
Internal
If you are using Mbox 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, select the
S/PDIF
option. This makes
Mbox clock to the external device’s clock.
Sample Rate
This drop-down menu sets the sample rate of
Mbox. 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 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 Control Panel.
When the sample rate is locked to an external digital clock source, the Mbox’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 blinks. (A message appears at the bottom of the Hardware Settings section stating that: “External clock not detected, Audio Streaming is Disabled.”).
Buffer Size (Windows only)
This menu sets the size of the input and output buffers on Mbox.
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 may not be able to make all the required audio calculations on time and you may hear pops, clicks, and stuttering in your audio streams. On the other hand, if the buffer size is set too high, your computer processes audio without incident, but your software may feel sluggish and unresponsive.
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 require you to re-launch the program before the new buffer size settings become active.
Chapter 4: Using the Driver Control Panel
25
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.
Soft Button Settings
The Mbox has four “Soft” buttons: Multi, +48v,
Mono, and Dim.
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. 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).
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 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
Post-Fader Meters
When this option is selected, fader positions 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 is heard from the mixer’s output, but you can still see if there is any activity on that input).

Stereo Mixes
This 8-input, 4-output mixer allows you to create two different stereo mixes from 8 input sources consisting of any of the hardware inputs
(i.e., analog and digital inputs) and software returns (software outputs). This allows you to 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 only affects what is audible from the mixer’s outputs—the stereo mix does not affect the signals that are sent to your DAW 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 makes the vocal part louder in the vocalist’s headphones, but it is still recorded into your DAW at the volume determined by the front panel Gain Adjustment
Knob.
The stereo is set up like a standard mixing console: There are 8 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 faders and mute button.
A pair of channels can be linked together by clicking the link icon between the two channels.
Linking channels allows you to adjust mute, solo, and fader settings simultaneously by modifying parameters on either one of the linked channels. However, linking two channels does 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 peak hold indication time as well as pre/post fader metering operation can be set from the Settings Tab of the
Control Panel. The clip indicators can be reset by clicking on the meter itself.
Keep in mind that setting or adjusting the stereo mix does not affect the signal that is recorded into your DAW. 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 still records into Pro Tools and play back properly.

Pan
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).
Link
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.
Links buttons
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.
Pan controls are unaffected by linking two channels.
Effects
The Effects section is where you set up “sendand-return” configurations, and select the effects that you apply to the Hardware Inputs and/or Software Returns.
Channel Labels
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.
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.

FX Returns
These knobs control how much of the Effect audio output is mixed in with the monitor signal
Master L/R outputs. Unlike sends, FX Returns are individually adjustable for each stereo mix.
The Clip LED shows clipping if the input to the
FX is clipping and if the output is clipping (the rest of the meter is just output).
Effect
The Effect drop-down menu is used to select the effect to be applied to the Hardware Inputs and/or Software Returns. 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.
