MBOX Control Software Overview 21
MBOX Control Software Overview
MBOX Control software lets you configure settings for your audio interface for use with Pro Tools, for other audio applications
that support the Core Audio (Mac) or ASIO (Windows) standard, and even for MBOX Studio as a standalone monitor controller.
MBOX Control provides a Toolbar across the top, the Channel Focus and Monitor sections along the left side, and Hardware In-
put, Software Input, and Hardware Output sections in the main part of the window. Channels can be renamed by clicking their dis-
played name.
Many features of MBOX Studio can be accessed directly from the MBOX Studio front and top panels, such as input gain, the tuner,
and monitoring volume. Many more parameters and features are available from the MBOX Control application, including its
on-board Avid FX (delay and reverb), EQ, User Action Button 1–4 assignments, footswitch settings, and more. All settings can be
saved as a User Layout Preset.

Mix Options
MBOX Studio can operate in either of two Mix Modes, Standard or Advanced, and both provide other options for output grouping and
mirroring. By default (and whenever Advanced Mix Mode is not enabled) MBOX Studio operates in
Standard Mix Mode.
To access Mix Modes and options:
Click the Mix Mode button.
The Mix Mode dialog opens. Available settings include:
•
Advanced Mix Mode
• Group All Monitor Mixes
• Mirror Main to S/PDIF
Standard Mix Mode
In Standard Mix mode, faders in the Hardware Input and Software Input strips control channel levels being sent to outputs and can be set
uniquely for each Hardware Output mix. Gain and other input parameters can be adjusted in Channel Focus.
One output channel (mono or stereo) is always selected, and only one output can be selected at a time. The only exceptions are ALT and
Bluetooth: Bluetooth output always mirrors ALT. Selecting either
Bluetooth or ALT selects both. ALT and Bluetooth still have inde-
pendent monitoring level, Mono, Mute, and Dim control. S/PDIF output can mirror MAIN (see
Mirror Main to S/PDIF), and you can
Group All Monitor Mixes.
For a signal flow diagram, see
Help.
Advanced Mix Mode
When Advanced Mix mode is enabled, you can access the “top of channel” input level by first deselecting all outputs and then adjusting
channel faders in the
Hardware and Software Input sections. Adjusting “top of channel” input faders affects all output mixes globally.
(For a signal diagram, see
Help.)
To use Advanced Mix mode:
1 Click Std Mix Mode in the Toolbar.
2 In the Mix Mode dialog select Advanced Mix Mode then click OK. The Toolbar button lights amber and displays Adv Mix Mode.
3 In the Hardware Output section, click the currently highlighted Output mix to deselect it (so no Output mixes are highlighted). Input
faders are set to unity (0 dB) and pans are centered.
4 Adjust controls in the Hardware Input and Software Input sections to affect that channel’s input controls in all outputs.
5 To adjust channel send level to outputs (as in Standard Mix Mode) select the desired Output.

Group All Monitor Mixes
When enabled, Alt, Headphone 1, Headphone 2, and Bluetooth outputs mirror Main. Group All Monitor Mixes can be enabled in either
Standard or Advanced Mix Mode.
• All Monitor outputs share the same Input to Output Mix. Individual mix layer controls are linked together so that, for example,
when you move the
Internal 1/2 fader in the single mix monitor group, that fader moves for all of those grouped/linked output mix-
ers).
• Main Mix Layer (which is only accessible in Advanced Mix Mode) is locked out for the user and input faders are set at unity and
pans centered.
• S/PDIF is included in the Monitor output single mix group if the
Mirror Main to S/PDIF preference is enabled.
• FX 1, FX 2/Hi-Z Output and ADAT 1–8 are not part of the single Mix monitor group and are mixed the same way as in Standard
Mix Mode.
Mirror Main to S/PDIF
When Mirror Main to S/PDIF is enabled, the mix routed to the MAIN output is also sent (mirrored) to the S/PDIF output. This provides
a convenient way to use the S/PDIF output as another monitor output option. Cycling through monitor outputs will cycle from Main, to
Alt to Dig (S/PDIF). When S/PDIF is selected, MUTE, DIM, and other monitor controls apply to the Dig (S/PDIF) output the same as
they do for MAIN and ALT.
User Action Buttons 1–4 Assignment
Each of the four User Action buttons can be assigned to perform two separate functions, one for when the corresponding User Action
button is pressed and a second function for when that button is pressed and held. The current User assignments are shown in the Toolbar.

AVID FX Delay
Item Description
Bypass Disables the effect.
Delay Time Sets the delay time between the original signal and the delayed signal (from 0.0 ms to 320 ms).
Rate Sets the rate of modulation of the delayed signal (from 0.00 Hz to 20.0 Hz).
Depth Sets the depth of the modulation applied to the delayed signal (from 0% to 100%).
Feedback
Controls the amount of feedback applied from the output of the delay back into its input (from –100% to
100%). It also controls the number of repetitions of the delayed signal. Negative feedback settings give
a more intense “tunnellike” sound to flanging effects.
LPF (Low Pass Filter)
Controls the cutoff frequency of the Low Pass Filter (from 10 Hz to 22 kHz). Use the LPF setting to atten-
uate the high frequency content of the feedback signal. The lower the setting, the more high frequencies
are attenuated. The maximum value for LPF is Off. This lets the signal pass through without limiting the
bandwidth of the plug-in.
Mix
Sets the balance between the delayed signal (wet) and the original signal (dry). If you are using a delay
for flanging or chorusing, you can control the depth of the effect somewhat with the Mix setting.

MBOX Control Software Overview

REVERB Controls
AVID FX Reverb
Item Description
Bypass Disables the effect
Size
In conjunction with the Room (Algorithm) control, adjusts the overall size of the reverberant space. There are three
sizes: Small, Medium, and Large. The character of the reverberation changes with each of these settings (as does the
relative value of the Decay setting). Size can be used to vary the range of a reverb from large to small. Generally, you
should select an algorithm first, and then choose the size that approximates the size of the acoustic space that you
are trying to create.
Room (Algorithm)
Selects one of seven reverb algorithms: Hall, Church, Plate, Room 1, Room 2, Ambience, or Non-linear. Selecting an
algorithm changes the preset provided for it. Switching the Size setting changes characteristics of the algorithm that
are not altered by adjusting the decay time and other user-adjustable controls. Each of the seven algorithms has a dis-
tinctly different character.
Decay
Controls the rate at which the reverb decays after the original direct signal stops. The value of the Decay setting is
affected by the Size and Algorithm controls.
HF Cut
Controls the decay characteristic of the high frequency components of the reverb. It acts in conjunction with the Low
Pass Filter control to create the overall high frequency contour of the reverb. When set relatively low, high frequencies
decay more quickly than low frequencies, simulating the effect of air absorption in a hall. The maximum value of this
control is Off (which effectively means bypass).
Diffusion
Sets the degree to which initial echo density increases over time. High settings result in high initial build-up of echo
density. Low settings cause low initial buildup. This control interacts with the Size and Decay controls to affect the
overall reverb density. High settings of diffusion can be used to enhance percussion. Use low or moderate settings for
clearer and more natural-sounding vocals and mixes.
Pre-Delay
Determines the amount of time that elapses between the original audio event and the onset of reverberation. Under
natural conditions, the amount of pre-delay depends on the size and construction of the acoustic space, and the rel-
ative position of the sound source and the listener. Pre-Delay attempts to duplicate this phenomenon and is used to
create a sense of distance and volume within an acoustic space. Long Pre-Delay settings place the reverberant field
behind rather than on top of the original audio signal.
LPF
Controls the overall high frequency content of the reverb by setting the frequency above which a 6 dB per octave filter
attenuates the processed signal. The maximum value of this control is Off (which effectively means bypass).

MBOX Control Software Overview
32
EQ
The lower section of Channel Focus is the built-in EQ.
Based on Avid ChannelStrip, MBOX EQ can be used either on channel feeds to MBOX outputs such as headphones, or applied to chan-
nel feeds to Pro Tools. Each Hardware Input channel (including Talkback) can have their own Channel Focus EQ settings.

Each fader strip provides a Pan knob, Solo and Mute buttons, input meter(s), and Avid FX Send level meters. Each fader adjusts the out-
put level of the input channel (the level fed to MBOX output mixes). These controls mirror the same settings in the Channel Focus tab,
letting you adjust pan, solo, and mute even when a channel is not the current channel focus.
Adjacent channels can be stereo-linked (see
Stereo Linking). Double-clicking on a channel strip collapses it to a narrow view, to con-
serve screen real estate. Double-click again to expand.
For more information on these and all other input controls, see

Loopback is not available at 176.4 and 192 kHz.
Buffer Size (Windows Only)
The Buffer Size (Hardware Buffer Size) on Windows controls the size of the buffer used to handle host processing tasks such as pro-
cessing with host-based, or “Native” plug-ins. Use low HW Buffer settings for audio recording (low latency). Use high buffer settings
for mixing and plug-in processing (high latency).

Safe Mode
(Windows Only)
On some Windows systems, the use of a large number of effects can cause Pro Tools or other DAWs to cause high CPU usage, which
can lead to drop-outs during playback.
To avoid drop-outs, make sure Safe Mode is enabled.
Input / Output Latency
(Windows Only)
These indicators provide latency values for MBOX Studio when used on a Windows computer.
Optical Format
The Optical ports on MBOX support both ADAT and S/PDIF formats. Use the Optical Format settings to specify which format you are
using.
Metering
Metering preferences let you optimize MBOX hardware and MBOX Control metering.
Monitor Switching
When enabled, Disable auto-muting makes on-screen Monitor output selection latching (no auto-mute of other outputs). When not en-
abled, Monitor output selection is non-latching (selecting a new output automatically mutes all others).
Headphones
Headphones preferences are available to fold either or both Headphones 1 and 2 stereo outputs to mono. This can be useful when you
are recording talent that likes to keep headphones off of one ear to hear their instrument or voice acoustically. If you had already con-
figured a stereo mix for headphones, folding to mono can let them hear everything they need.
Dim Level
Lets you configure DIM to apply globally (all outputs) or per channel (only Dim the currently selected output).
If drop-outs contiune even with Safe Mode enabled, try reducing the number of Avid FX and/or plug-ins in your session.
MBOX Input and Output Latency
Item Description
Input Latency Shows the input latency of the audio driver.
Output Latency Shows the output latency of the audio driver.
For more information, see Audio Input and Output.
MBOX Metering Preferences
Item Description
Pre/Post
Sets meters to indicate pre- or post-fader levels. When pre-fader metering is selected, the level meters show levels
independent of fader position. With post-fader metering, the level meters respond to fader position.
Clip Threshold Sets the level in decibels (dB) at which meters indicate clipping (red).
Peak Release Sets how long meter peaks are displayed. Enter a value for the number of dB per second for meter peaks to recover.
Clip Hold Sets how long clips are indicated in meters.
Infinite Hold If you clip, you’re gonna have to look at it for your whole session.

MBOX Control Software Overview
37
FX Loops
Lets you switch FX 1 or FX 2 outputs to Hi-Z (high impedance) to integrate guitar pedals (“stomp boxes”), many of which expect a
high-impedance signal at their input. When using rack mount or other Line level devices in MBOX effects loops, disable these settings.
Hi-Z Out to Amp

MBOX Studio Basics
The following are some basics to get you started learning your way around MBOX Studio and MBOX Control software.
Top Panel
The top panel provides input controls on the left, meters and global controls in the center, and output controls on the right.
Left and Right Dual-Function Encoders
The large left (input) and right (output) encoders on the top panel are dual-function rotate/press controls. The encoders and their other
associated input or output controls provide direct access to many of the most often used functions such as phantom power and stereo
linking for inputs, monitor volume and mute, and Talkback.
For both the input and output sections, you first focus on a hardware input or output, then use the top panel controls to affect whichever
input and output channels are their respective
Hardware Focus.
Hardware Focus
The top panel controls affect the currently focused hardware input or output. For example:
To focus and adjust a vocal mic input:
1 Press the left encoder repeatedly until the connected input (1, 2, 3, or 4) lights green above the input meters.
2 Press the top panel INPT button repeatedly until MIC is lit green above the input gain indicator, which is also lit green.
3 Rotate the left encoder to increase or decrease input gain.
To focus and adjust a Monitor output:
1 Press the right encoder repeatedly until the desired output (such as MAIN for the Main Left/Right monitor outputs) is lit green above
the output meters, which are also lit green.
2 Rotate the right encoder to increase or decrease volume.

MBOX Control
MBOX Control software provides a row of hardware inputs across the top, a row of software inputs (“internal” sources from Pro Tools
or other application) in the middle, and a row of hardware outputs across the bottom.
Channel Focus
On MBOX Studio, the encoders and buttons in the input and output sections affect the currently focused (selected) MBOX Hardware
Input or Hardware Output channel (for more information see
Hardware Focus).
In MBOX Control the Channel Focus tab shows all parameters for the currently selected channel or bus. That selected channel or bus
is indicated on-screen with a lit colored border. The color corresponds to the currently selected Output mix. For example, when Main
is selected in the Hardware Output section, all input fader caps light in the same green color as Main.

Pro Tools Sources
Audio from Pro Tools or other DAW can be mixed into the currently selected output using the Internal 1–8 channel strips in the Soft-
ware Input section.
Custom Headphone Mixes
To create custom cue mixes for headphones or any hardware output, see Output Mixes for Speakers and Headphones. Custom head-
phone mixes can be saved as an MBOX Control Preset (see
Presets).
Output Mixes for Speakers and Headphones
In MBOX Control, select any output to set up its own unique mix.
To set up and control Main and Alt monitor mix:
1 Begin playing or playback.
2 Select Main by clicking its strip in the bottom row. All input fader caps are colored to match that of the currently selected output mix
(such as green for Main).
3 Adjust input channel levels and other parameters as desired.
• To include a hardware input, adjust that input in the top row of channels (Hardware Input).
• To include audio from Pro Tools or other DAW, adjust the Software Input. Note that Pro Tools tracks must be routed to MBOX Stu-
dio Internal 1–2, 3–4, 5–6, or 7–8. For more information see
Configure Pro Tools for MBOX Studio.
• To access all controls for an input channel, click on a channel strip to focus it, then use the controls in Channel Focus.
4 Optional: Adjust settings for the focused output mix using its channel strip controls such as Vol (volume) and Trim. Additional Mon-
itor controls are available in the
Monitor section of MBOX Control.
5 Click to select a different output (such as Alt) then repeat the previous steps. Input level settings are saved uniquely per output mix.
To set up Heaphone 1 or 2 mix:
Click to select Headphone 1 or Headphone 2. and repeat the previous steps to set input levels feeding the cue mixes for each head-
phones output.

Stereo Linking
All input channels and some Hardware Output channels provide Link buttons. When enabled, the parent channel is stereo linked to its
adjacent channel. When two channels are linked, their single level, gain, and other input controls affect both channels identically.
When two mono channels are initially linked to become stereo, settings for the left channel are copied to the right channel. When a stereo
channel is unlinked, settings are copied to both resulting mono channels.
Channels can be linked and unlinked from MBOX Control, and from the MBOX Studio top panel.
To link or unlink channels using MBOX Control:
Click the Link icon in either adjacent channel strip.
To link or unlink channels using MBOX Studio top panel:
1 Press the left encoder repeatedly to cycle through available hardware inputs until one of the desired inputs is selected.
2 Press the LINK button to link (it lights green) or unlink (unlit).
When linked, both the selected channel (such as 5) and the adjacent channel (6) light green above the input meters, and the LINK button
also lights green.
Reset and Fine Control
When adjusting on-screen controls in MBOX Control:
To reset a control to its default setting, Option-click (Mac) or Alt-click (Windows) on the control.
To adjust a knob or fader with finer resolution, hold Command (Mac) or Control (Windows) while adjusting the control.

Audio Input and Output
You can select (focus), configure, and control MBOX Studio audio inputs and outputs from the top panel and from MBOX Control.
Some parameters and settings are only available from MBOX Control.
Audio Input
This section shows how to select and adjust inputs.
Quickstart
• Focus on a hardware input (press the left encoder repeatedly, each press selects the next input).
• Set the input type for mic, line, or instrument (press the INPT button repeatedly).
• Set other input settings (use top panel buttons for some, use MBOX Control for all input controls).
• Adjust input gain (rotate the left encoder).
Microphones
To use a mic input:
1 Select the desired hardware input (1–4, whichever input your mic is connected to) by repeatedly pressing the left Encoder to cycle
through available inputs. The number of the currently selected input is shown above the meter.
For example, if you connected a microphone to Mic/Line Input 3 on the back panel, repeatedly press the left Encoder until 3 is lit
green above the channel 3 Input meter.
2 Make sure MIC is selected and lit green above the input gain indicators. If it is not, select the appropriate input type (MIC, LINE, or
INST) by pressing the INPT button to cycle through types. Depending on the currently selected hardware input, choices include Mic
(green), Line with gain control (yellow), and Inst (amber) for input 1.
3 If your microphone requires phantom power, press the 48V button so it becomes lit.
4 Optional: Select a Variable Z impedance setting by pressing the top panel Z button. When a hardware input is set to Mic, choices in-
clude 1k (Z lights magenta), 5k (white), and 10k.
If you are not sure which setting to use, start at the 5k setting (white). For more information, see
About Variable-Z.
5 To invert polarity, apply the Soft-Limiter, or engage the HPF (high-pass filter), do the following in MBOX Control:
• Make sure the desired channel is selected and shown in Channel Focus.
• Click the desired controls so they become lit. For polarity click
Ø, for the Soft-Limiter click Soft Lim, and for the high-pass filter
click
HPF.
Connect microphones, guitars, and other input sources to MBOX Studio (see

8 To start recording in Pro Tools, see
Using MBOX Studio and Pro Tools. To start using the built-in Avid FX for EQ, reverb, and delay,
see Using AVID FX.
Electric Guitar and Bass
Connect electric guitar and bass to hardware inputs 1 and 2 on the front panel. Each of these hardware inputs accept 1/4-inch TS
(tip/sleeve) instrument connections, and provide Variable-Z impedance selection for compatibility, tone, and “feel.”
Variable-Z alters the frequency response of a guitar signal by loading the pickups in the same manner as plugging into a real amp or ef-
fect. This setting only affects instruments with passive pickups. Generally, the lower the impedance setting the darker it might sound
(not all pickups respond in the same way).
To use an electric guitar:
1 Select the desired input (1–2, whichever input your guitar is connected to) by repeatedly pressing the left Encoder to cycle through
available inputs. For example, if you plugged your electric guitar into Mic/Line/Inst
1 on the front panel, repeatedly press the left En-
coder until 1 is lit above the Input meters.
2 Select the appropriate input type by repeatedly pressing the INPT button to cycle through types until INST is selected (lit amber).
3 Experiment with different input impedance settings by doing the following:
• Press the Z button repeatedly to cycle through available impedance-only settings (the button changes color for each available set-
ting).
• To use an impedance + capacitance (Cap) setting, select any impedance setting then press and hold the
Z button (it begins to slowly
pulse, indicating “+ CAP” mode). For more information, including a list of available settings, see
About Variable-Z.

Stereo Line Input
In addition to inputs 1–2 and 3–4, MBOX Studio provides Line Inputs 5–6 on the back panel, to connect stereo sources such as sam-
plers, turntables, and synthesizers.
To use a stereo source:
1 Connect the left and right outputs of your stereo source device:
• Use MBOX Studio LINE IN 5–6 inputs for the left and right outputs from synths, drum machines/samplers, turntables, external
sub-mixers, and similar “line level” sources.
• To use a stereo pair of microphones or other sources, connect them to any pair of MBOX Studio inputs. For example, for two XLR
microphones use inputs 1 and 2 on the front panel, or 3 and 4 on the back panel.
2 Press (or press and rotate) the left encoder until 5 and 6 light green above the Input meters. Line Inputs 5 and 6 are linked by default,
so you only need to select input 5 to automatically select both 5 and 6.
Input type (
LINE) is automatically selected for hardware inputs LINE IN 5–6.
3 Rotate the left encoder to adjust input gain.

About Variable-Z
(Variable Impedance)
MBOX Studio Mic/Line/Inst inputs 1–2 and Mic/Line inputs 3–4 provide Variable-Z input impedance selection for mic, instrument,
and effect compatibility, tone, and “feel.” In addition, FX Sends 1–2 offer optional Hi-Z output impedance. Using different impedance
settings on microphones gives different tonal characteristics to the mic. With guitar, Variable-Z alters the frequency response by loading
the pickups in the same manner as plugging into a real amp or effect. This setting only affects instruments with passive pickups. Gen-
erally, the lower the impedance setting the darker it might sound.
FX Sends 1–2 on the back panel operate by default at Line/Lo-Z for connection to external, line level devices such as effects proces-
sors. These outputs can be individually switched to Hi-Z (high impedance) for connection to stomp boxes and other devices that expect
a high impedance signal. The front panel
Hi-Z Out to Amp connector always operates at high impedance. An optional ground (earth)
lift can be applied in MBOX Control
Preferences. (The Hi-Z Out to Amp mix always mirrors FX Send 2.)
+ CAP
Impedance settings with “+ Cap” in their name indicate settings that also apply modeled input capacitance. Variable Z is an all analog
circuit including the + Cap capacitor. For a basic guideline, try one of the + Cap settings when using an amp simulation plug-in preset
that has a tube (valve) amp, or a stomp box as the first device in the chain. In MBOX Control you can choose a
+ Cap setting from the
Z selector in Channel Focus. You can also choose +Cap settings from the MBOX Studio top panel.
To choose + CAP values using the MBOX Studio top panel:
1 Press and hold the Z button to enter +CAP mode. The Z button pulses slowly to indicate impedance settings are now including +CAP.
2 Press Z again to exit +CAP mode to cycle through impedance values without +CAP. Button should reflect value selected in software,
solid color without +CAP and slight pulsing color with +CAP.
Mic and Instrument Impedance Settings
The following impedance settings are available for mic and instrument inputs. (For a good explanation of input impedance and some
specific recommended settings for different equipment, see The Truth about True-Z.)

Using MBOX Studio and Pro Tools
Pro Tools and MBOX Studio optimize tracking and mixing workflows by providing tactile control of many frequent tasks including in-
put selection, discrete headphones/cue setup and mixing, and more.
When Pro Tools and MBOX Studio have been installed for the first time, Pro Tools automatically detects MBOX Studio as the
Playback
Engine
, and configures I/O Setup with default MBOX Studio Input, Output, and Bus paths.
When opening sessions created on a different system without MBOX Studio, be sure to check the Playback Engine and if necessary se-
lect MBOX Studio.
Recording and Tracking
MBOX Studio provides up to 21 discrete hardware inputs (at 44.1/48k) that are available in Pro Tools as track input paths. In MBOX
Control, these are the channels in the Hardware Input section. Use these controls, and the complete set of controls in Channel Focus, to
shape the sounds of what you will record in Pro Tools.
MBOX Studio also provides 8 channels of “returns” (outputs) from Pro Tools or other software. In MBOX Control, these are the chan-
nels in the
Software Input section. Use these for your speakers and headphones.
Recording Audio
To record an audio track:
1 Make sure you have already installed Pro Tools, set up the
Playback Engine and I/O Setup for MBOX Studio and MBOX Control,
and confirmed speakers, headphones, or other Audio Output for monitoring.
2 If not already running, launch MBOX Control (press the MBOX button on the top panel, or manually launch it on your computer).
then click the gear icon to open Preferences and do the following:
• Configure
Clocking Options: Choose a Clock Source and Sample Rate for your session.
• (Optional) Configure Metering.
3 In Pro Tools, create one or more audio tracks for what you want to record.
4 From the track’s Input Path selector, select the MBOX Studio input(s) you want to record (such as Mic/Line 3).
5 From the track’s Output Path selector, select the MBOX Send 1–2 (Stereo) monitoring path.
Pro Tools Artist can use up to 16 of the available hardware inputs simultaneously. Pro Tools Intro can use up to 4.
If you are new to Pro Tools, see the Pro Tools Quick Reference Guide, available from the Getting Started tab of the Pro Tools Dash-
board (File > Open Dashboard). For complete Pro Tools documentation, choose Help > Pro Tools Help.
If recording electric guitar, consider creating and recording to two mono audio tracks: one for the sound of your guitar through any
pedals, effects, amps, or microphone(s), and a second track to record a “dry” (direct) signal. Then use the dry track for
Re-Amplifi-
cation through the Hi-Z Output to Amp.

Setting Up Pro Tools for Headphone Mixes
MBOX Studio provides 8 channels of inputs from Pro Tools in the Software Input section. The following example suggests one way
you can configure Pro Tools signal routing for maximum flexibility when creating and managing headphone mixes.
To configure Pro Tools for headphone mixes:
1 Include an “everything” mix by making sure your stereo Pro Tools mix is assigned to MBOX Studio Internal 1–2. This could be from
an Auxiliary Input that is submixing all Pro Tools audio, or directly from each Pro Tools track output.
2 Next, use Pro Tools Sends and Auxiliary Inputs to set up submixes for up to 6 mono or up to 3 stereo sends that need to be individually
adjustable in each different mix. For example, to create an Auxiliary Input for a stereo submix of all drums do the following:
• Select all the drum tracks.
• Hold Option+Shift (Mac) or Alt+Shift (Windows) and click an available Send selector on any of the drum tracks.
• Choose
new track...
• The New Track dialog opens pre-configured to create one new stereo Auxiliary Input track. Enter a custom name for the new track
(such as “Drums cue”) and click OK.
Pro Tools adds a new Send to each selected track, creates a new stereo bus, creates a new Auxiliary Input, and automatically assigns
its input to the newly created bus.
3 Assign the new Auxiliary Input track’s output to an available MBOX Send (such as MBOX Studio Internal 3–4 for a stereo send, or
an available sub-path such as MBOX Studio Internal 3 for a mono send).
4 For each track (each drum track in this example) click the newly added send to open its control window, then raise the fader to set
how much of the track signal is sent to the Auxiliary Input.
5 Raise the Auxiliary Input fader as needed to send sufficient signal back to MBOX Studio.
6 In MBOX Control, make sure to select the desired output mix (such as Headphone 1) then raise the appropriate Software Input fader
(such as Internal 7) to include its Pro Tools source audio in the selected output mix.
7 Repeat for other instruments, submixes, or tracks.

MBOX Reverb and Delay
MBOX Studio includes built-in EQ, delay and reverb using AVID FX.
• Use built-in 4-band EQ on input channels. Channel EQ can be applied to headphone and other MBOX Studio monitoring outputs
only, or applied to the channel send going to Pro Tools.
• Use AVID FX Delay and Reverb to have effects in headphones or other mixes for low latency monitoring.
AVID FX send faders are available on all input channels to set the level being sent to effects (all channels share the same delay and re-
verb settings).
Using AVID FX for Headphone Mixes
To apply AVID FX delay and reverb to a headphone mix:
1 In MBOX Control, click to select Headphone 1 or Headphone 2 in the Hardware Output section.
2 Adjust Hardware Input and Software Input levels and pan.
3 Click to select the first desired input channel. That channel is shown in Channel Focus.
4 In Channel Focus, raise the Avid FX Send fader until you see levels on its meter. The Channel Focus AVID FX Send fader controls
the FX send level for the currently focused channel.
5 Optional: Enable PRE to make the AVID FX send be tapped at the “top of channel” (meaning without any Channel Focus EQ).
6 Click AVID FX to open the AVID FX tab.
7 In the Hardware and Software Input sections all fader caps light purple; adjust a purple input fader to set its AVID FX Send level.
8 In the Hardware Output section the knobs at the top of each channel strip light purple; adjust a purple output channel encoder to set
the AVID FX Return level to that individual output.
9 Make sure the Avid FX Return Level is not muted, then raise the fader. This fader controls the level of AVID FX being returned in
all outputs.

11 Adjust individual channel AVID FX Send levels using their purple faders in the Hardware Input, Software Input, and Hardware Out-
put sections. Adjusting the AVID FX Return faders on output channels lets you quickly raise or lower all effects in headphones or
other mixes.
Using AVID FX EQ
Channel Focus provides a 4-band parametric EQ for each Hardware Input channel. The built-in 4-band EQ can be used either on channel
feeds to MBOX Studio outputs such as headphones, or it can be applied to channel feeds going to Pro Tools.
To use AVID FX EQ:
1 Click to select the first desired input channel. That channel is shown in Channel Focus.
2 In the EQ section, make sure the Bypass button is off (not lit).
3 Adjust band parameters by clicking and dragging breakpoints in the graph. Or use the controls below the graph (click to select a band
(
LF, LMF, HMF, or HF) then adjust the available controls).
4 Repeat for other bands.

Re-Amplification
Re-amplification is the process of sending pre-recorded audio to an external amplifier and then re-recording the processed audio to a
new track. Often used on guitar tracks that were recorded direct, with no effects or amps, re-amplification can provide the same tonal
options, ambiance, and flexibility to vocals, drums, sound effects, and virtual instrument tracks.
Tracks can be sent from Pro Tools through the
Hi-Z Out to Amp output on MBOX Studio into one or more external amps or processors
and re-recorded through an MBOX Studio input.
A ground lift is provided on Hi-Z Out to Amp, providing the correct type of buzz kill when necessary.
The Hi-Z Out to Amp output and FX Send 2 always carry the same output mix.
To send a signal out the Hi-Z Output to Amp for re-amplification with an external amp:
1 Connect a TS (Tip/Sleeve) cable from the Hi-Z Out to Amp on MBOX Studio front panel to the input of your amp or other device.
2 Position and connect a microphone to an available MBOX Studio Mic/Line input, such as Mic/Line/Inst 1 on the front panel. (If you
need to change input focus, type, or other parameters, see
Audio Input and Output.)
3 In Pro Tools, choose the track to be re-amplified and assign its output to MBOX Studio Internal 8.
4 Create a new audio track and assign its input to the MBOX Studio input you connected the microphone to in step 2, above (such as
Mic/Inst/Line 1).
MBOX Studio also provides FX Loops 1–2 for integrating pedals, stomp boxes, and other effects devices. See Using FX Loops.

put section) to adjust the level going to the amp.
7 While the track and session play, dial in the amp sound (adjust amp gain, volume, and tone controls as desired).
8 Set MBOX Studio input gain so input meters light green most of the time, and only light amber for louder signals.
9 In Pro Tools, record enable the destination (record) track for the re-amplified signal you created in step 4, above. Adjust device levels
as needed to have the Pro Tools track meter (on the recording track) only light amber when the loudest parts are playing.
10 When ready:
• Locate Pro Tools to the beginning of the material you want to re-amplify.
• Click Record in the Transport window to arm Pro Tools for recording. The Record button flashes red.
• Make sure the destination track is record enabled (its record button also flashes red) and then click Play or press the Spacebar.

Using FX Loops
MBOX Studio provides two FX Loop inserts on the back panel. These four jacks (FX Sends 1 and 2, and FX Returns 1 and 2) let you
integrate external effects processors that can be applied to MBOX Studio audio, or to Pro Tools tracks. FX Sends 1 and 2 can be also
be used for additional outputs, and FX Returns 1 and 2 as additional inputs.
Both FX Sends 1 and 2 can be switched to high impedance (Hi-Z) when connecting to stomp boxes (guitar pedals) or other devices that
expect a high impedance signal at their input. Otherwise FX Sends operate at line level, to integrate rack mount or any other type of de-
vice that expects a line level input. You can enable or disable Hi-Z on each FX Send separately in
Preferences.
To use FX Loops:
1 Using 1/4-inch TS instrument cables, connect your device(s) to FX Sends 1 and/or 2:
• Connect FX Send 1 to the input of a mono device (such as a guitar pedal).
• Connect the output of that device to FX Return 1.
• If using a 2nd device, repeat the previous two steps to connect it to FX Send 2 and FX Return 2. Or connect multiple mono pedals
in series to either FX Loop 1 or FX Loop 2.
• If your external device is stereo, connect FX Send 1 to the left input of the device, and FX Send 2 to the right input. Then connect
the L and R outputs of the device to FX Returns 1 and 2, respectively.
You can also use the S/PDIF Out and In connectors to connect external digital devices such as a multi-effects box. See
Using S/PDIF.

To use S/PDIF for digital monitors:
1 Using RCA cables, connect MBOX Studio S/PDIF Out to the S/PDIF input on the first S/PDIF monitor, then use another RCA cable
to daisy-chain to the second monitor.
2 If necessary, configure the digital monitors for the same sample rate as MBOX Studio. (MBOX Studio does not provide sample rate
conversion (SRC) on the S/PDIF output, so external devices must be set to either the same sample rate as MBOX Studio, or have SRC
applied at their S/PDIF input (if available).
3 In MBOX Control, click Std Mix Mode in the Toolbar then select Mirror MAIN to S/PDIF. The Main mix is mirrored at the S/PDIF

Reducing Monitoring Latency
There will inevitably be some audio delay, or latency, in the monitoring signal (even if only a few samples) due to the process of con-
verting an analog signal to a digital signal (input) and back again (output). There may be additional latency due to mixer configurations
and processing.
Software-only (also known as “Host-based”) Pro Tools systems use the host processor in your computer for all audio processing, play-
back, and recording, so there is always a small amount of latency in the system. For example, there may be some audible delay between
the incoming signal and outgoing signal when monitoring recording through Pro Tools.
Low Latency Monitoring
MBOX Studio can use the Low Latency Monitoring option in Pro Tools to record with an extremely small amount of monitoring latency.
(Likewise, certain Core Audio and ASIO audio interfaces that have a built-in mixer can use the Low Latency Monitoring option.)
In Pro Tools, enabling Low Latency Monitoring automatically bypasses plug-ins and sends on record-enabled audio tracks. You can use
MBOX Control to set up its on-board delay and reverb to be able to provide low latency monitoring with effects.
Configuring Pro Tools for Low Latency Monitoring
To use Low Latency Monitoring:
1 Record enable audio tracks by clicking their Record Enable buttons.
2 Select Options > Low Latency Monitoring.
When Low Latency Monitoring is enabled, any plug-ins and sends assigned to record-enabled tracks are automatically bypassed, and
must remain bypassed. Also, these tracks do not register on meters for Master Faders.
Pro Tools Preference to Allow Sends to Persist During LLM
All plug-ins and sends are bypassed by default when Low Latency Monitoring (LLM) is enabled (Options > Low Latency Monitoring).
Enable the
Allow Sends to persist during LLM preference to maintain sends audio signal output with Low Latency Monitoring.
To maintain (or bypass) sends with Low Latency Monitoring enabled:
1 Choose Setup > Preferences and click the Mixing tab.
2 Select (or deselect) the Allow Sends to persist during LLM option.
3 Click OK.
For more information on Low Latency Monitoring see Help > Pro Tools Help.
