Chapter 1: Introduction
Pro Tools | MTRX Studio
Welcome to Pro Tools®| MTRX Studio. MTRX Studio is an extremely versatile multi-channel audio interface for Pro Tools | HDX
and Pro Tools | HD Native systems. MTRX Studio supports 16- and 24-bit audio with sample rates of 44.1, 48, 88.2, 96, 176.4, and
192 kHz. MTRX Studio provides two DigiLink™ Mini ports for up to 64 input and output channels with Pro Tools. MTRX Studio
provides 16 analog line inputs, 16 analog line outputs, two analog monitor outputs, two headphone outputs, and two analog inputs
for microphones or instruments. It also provides a 64 I/O channels Dante®IP Audio interface and 16 channels of ADAT™I/O,
Word Clock and Loop sync synchronization, and an input for a foot switch (for various DADman functions, such as talk back re-
mote control). Additionally, MTRX Studio provides built-in SPQ processing for room tuning, bass management, and equalizing of
cue and monitor signals.
MTRX Studio can be used a traditional recording interface, with mic and line analog I/O, phantom power, and two headphone jacks
on the front panel. MTRX Studio can also be used as a monitor controller output device for immersive audio post production ap-
plications with up to 9.1.6 channel layouts. Pro Mon monitor control functionality is available for EUCON™-enabled Avid devices
with MTRX Studio using DADman software.

Control, Routing, and Processing
• Operation using DADman software—some settings can be controlled on the front panel
• All settings controlled over Ethernet
• 512x512 cross-point matrix
• 256x32 summing (Pro | Mon) with monitor profiles
• SPQ processing with 256 filters for 16 channels of speaker EQ
Router Functions and Principle
In addition to the AD/DA conversion and digital I/O functionality, MTRX Studio provides a powerful router matrix. All input signals
can be patched to one or more outputs on a mono-channel basis, so MTRX Studio is also a digital patch bay. Use DADman software
on your computer to configure and control MTRX Studio over Ethernet.
In order to set up the correct signal flow in MTRX Studio, the correct connections have to be set in the matrix using DADman software.
Any one of the analog or digital inputs installed in the MTRX Studio can be patched to any analog or digital output, or can be split into
multiple outputs.
DADman lets you import, edit, and save DADman settings files (.dms files), when includes the AD, DA, Monitor (if any), Connections,
and Configuration settings. DADman also lets you import, create, and edit separate monitor profiles (.dmprof files). A monitor profile
is a matrix configuration that lets you select from multiple sources and outputs, with or without fold downs and external metering, for
monitoring workflows. Monitor profiles are customizable from mono to Atmos (16 speakers) and can be controlled from the front panel
of MTRX Studio and by EUCON, as well as from within DADman.
You can configure DADman to automatically load your last .dms and .dmprof files on launch in the DADman Preferences (Mac) or
Options (Windows).

For example, with sixteen analog input channels, each can be patched to Pro Tools Output channels and the Pro Tools input can be
patched to sixteen ADAT output channels. At the same time, two channels can be patched to the analog output.
It is essential that all digital signals connected to the MTRX Studio are synchronized to the same basic clock signal.
In order to patch IP Audio channels between different devices, use the Dante Controller software tool from Audinate (visit
www.audinate.com).

Reconfig Button
The Reconfig button on the back of MTRX Studio should not be used during normal installation. It is intended only as for recovery
in case something goes wrong during programming of IP addresses or a software upgrade (such as an unintended power loss). It
lets you start MTRX Studio in various basic modes so it can be restored without having to be returned to the factory.
The Reconfig button is accessed through a hole in the rear panel using a pen or a similar pointed item (such as a paper clip). A green
LED is visible through the hole. When the Reconfig button is activated, the LED lights to indicate the two Recovery modes for
MTRX Studio: last used IP Address and DHCP.
Recovery Mode
Use Recovery mode if the software in the MTRX Studio is not operative. In Recovery mode only basic boot software is operative
in the unit, and new software can be downloaded using DADman software.
To enter Recovery mode using the last used IP address settings:
1Power off MTRX Studio.
2Press the Reconfig button using a pen or a similar (such as a paper clip) and power the unit on. Hold while the unit is powering
up.

The green LED turns on and MTRX Studio enters Recovery mode. The IP address settings of the unit are the last setting used in
the unit.
To switch Recovery mode to use DHCP:
While the unit is in Recovery mode and the green LED is on, briefly press the Reconfig button again.
The green LED turns off, but the MTRX Studio remains in Recovery mode and the IP address settings of the unit is set to DHCP.
In case there is no DHCP server on the network, the MTRX Studio defaults to IP address 10.0.7.20 / 255.255.0.0 after approxi-
mately 2 minutes.
The selection of either of recovery mode are fixed after selection. MTRX Studio starts with a basic boot software and IP configu-
ration. MTRX Studio will not be operational until a proper firmware has been downloaded using the DADman software and the
unit has been powered off and back on again. By enabling recovery mode with default IP address and network configuration the
unit can always be identified on a network using the default setup.
Restore Defaults
In Restore Defaults mode, all settings of the unit are initialized and reset to the factory programmed defaults. However, the IP ad-
dress settings of the unit are remain unchanged and do not return to factory default.
To restore the default settings to MTRX Studio:
1While the unit is powered on and operating normally, push and hold the Reconfig button for 10 seconds.
2Release the Reconfig button.
When the Reconfig button is released the firmware of the unit restarts with the factory default settings and enters normal operation
automatically.
Note that the IP address referred to is the IP address of the controller/management interface of the unit.This is not the IP address
of the IP audio interface. This IP address can not be accessed in recovery or restore defaults mode.

DADman Software 13
DADman Software
Use DADman software to configure and control MTRX Studio over Ethernet.
Assigning the IP Address for your Computer and MTRX Studio
Before using DADman with MTRX Studio units on your network, you must set the network configuration for each MTRX Studio
unit in your system, one at a time. You can use fixed IP addresses or IP addresses assigned by DHCP.
Fixed IP Address
You must have a preferred range of IP addresses, and a network mask for the computer network and the connected MTRX Studio
units.
To use a fixed IP address:
1Configure your computer IP address and network mask using the macOS System Preferences or the Windows Control Panel to
10.0.7.25 | 255.255.255.0.
2Launch DADman.
3Choose Settings > Device List.
4Click Refresh to discover the MTRX Studio on the network.
5Right-click the MTRX Studio and choose Network Settings.
When using MTRX Studio units in Pro Tools systems with EUCON peripherals (such as S6, S1, or Control app), use adedicated
Network Interface for EUCON peripherals and connect all other network devices to a separate Network Interface (for MTRX
Studio/DADman, Dante audio, local network, internet, and so on). Using separate Network Interfaces is especially important
when streaming audio over Dante.

6Configure each MTRX Studio unit in turn with a unique IP address and the preferred network mask, for example 10.0.7.21 |
255.255.255.0. You can also configure IP audio network settings in this window.
7When you are done you can connect more than one MTRX Studio to the network, and each one appears in the DADman Device
List.
Automatic IP address
You must have a network with a DHCP server to allocate the IP addresses.
To use an automatic IP address:
1Configure your computer IP address to DHCP using the Mac System Preferences or the Windows Control Panel.
2Launch DADman.
3Choose Settings > Device List.
4Click Refresh to discover the MTRX Studio on the network.
5Right-click the MTRX Studio and choose Network Settings.
6Configure each MTRX Studio in turn to use DCHP.
