Mbox Hardware Overview

Mbox Front Panel Features

Figure 1 identifies controls, indicators, and input and output ports on the front panel on the Mbox.
Figure 1. Mbox front panel
Instrument Inputs
Use these 1/4-inch TS inputs are for connecting an electric guitar, bass, or other instrument-level device. The level for these inputs is controlled by the Gain Controls.
Front/Rear Source Selectors
These buttons select either the front panel In­strument Inputs (TS) or rear panel Mic/Line In­puts (XLR/TRS combo) for each channel. When the button is set to the Out position, the front panel Instrument Inputs are active. When the button is set to the In position, the rear panel Mic/Line Inputs are active.
Chapter 2: Mbox Hardware Overview 5
Gain Controls/–20dB Pad
About Phantom Power
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.
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.
+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.
Dynamic microphones (such as Shure SM57s or M-Audio Aries) do not require phantom power to operate, but are not harmed by it. Most con- denser 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.
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.
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 Guide6
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.
Front Panel Headphone Output
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).
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.

Figure 2. Mbox back panel
USB Port
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 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.
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.
Mbox User Guide8
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.

Audio Inputs

Mbox provides two channels of analog inputs, and supports microphones, guitars, keyboards, and other types of instruments and devices.
Mbox has two audio input sections, labeled In­put 1 and Input 2. For stereo inputs, use Input 1 for the left input, and Input 2 for the right in­put.
The two input sections are located so that the hardware input jacks line up directly behind their corresponding input controls on the front panel. This makes it easier to locate channel in­put connections from the front.
Inputs on front panel of Mbox
To connect to a stereo system:
When connecting to a stereo system, connect
the left channel of the stereo (often the white plug) to Monitor Output 1, and the right chan­nel of the stereo (often the red plug) to Monitor Output 2.
Home stereo systems often use RCA connec­tors. You can use an adaptor or a special ca­ble to convert from the 1/4-inch TRS (Tip­Ring-Sleeve) connectors used by Mbox to the RCA connectors on your home stereo.

Mic Cables and Connectors
Use a microphone with an XLR connector to connect the microphone to the Mbox.
The Mbox 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 by a mic preamp in a mixer or audio interface (such as Mbox) that can supply power through the mi­crophone cable.
Rear panel analog input connectors
Most condenser microphones (such as an M-Audio Solaris) require phantom power to op­erate. Dynamic microphones (such as a Shure SM57 or an M-Audio Aries) 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.

Using the Driver Control Panel

The Mbox Driver Control Panel lets you config­ure settings for your audio interface for use with Pro Tools or other audio applications that sup­port the CoreAudio (Mac) or ASIO (Windows) standard.
For information on configuring applications other than for use with your interface, see “Using Third-Party Applications” on page 37.
Several features of Mbox can be accessed directly from the Mbox 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. (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
The Horizontal layout is the default layout. It shows all knobs, faders, meters and buttons in a layout similar to that of a mixing console. The Horizontal layout is used for all the screen cap­tures in this chapter.
Horizontal (Meters Only)
The Meters Only layout emphasizes pre-fader hardware input and software return metering, but does not provide access to the stereo mixers.
The Preset view lets you load and save Mbox Set­tings files, which contain all settings of the Mbox 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 ti me you work on a di ff er ent type of project.

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
Tun er
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
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.
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.
Mbox User Guide24
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.
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.
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
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).
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).
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.

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 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.
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.

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
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 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.
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.
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.
The Channel Labels also display the signal level (in dB) while a fader is being adjusted.

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 E ffect drop-down m enu is used to s elect 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.
Vol ume This knob controls the effects output level being sent to the FX Returns.
The Master section is for monitoring the main mixer output. This output can be routed to any hardware output. Each Stereo Mix includes mas­ter section with several controls:
Master Fader Adjusts the overall level of the ste­reo mix.
Balance Knob Adjusts the left/right balance of the stereo mix (double-click the knob to return it to center).
