Chapter 1: Introduction
16-channel MADI Effects Processor For Live Mixing With UAD Plug-Ins
UAD‑2 Live Rack is a 16‑channel MADI effects processor for live sound engineers to
craft their mixes using Realtime UAD Processing and industry‑leading UAD plug‑ins —
including Antares Auto‑Tune Realtime — right out of the box. Up to four UAD‑2 Live
Rack units can be combined for up to 64 channels of MADI signal processing via Mac
Thunderbolt.
Realtime UAD Plug-In Processing
With its Realtime UAD QUAD Core Processing, UAD‑2 Live Rack lets engineers enhance
their live mixes with the world’s best analog emulations, courtesy of Universal Audio’s
acclaimed UAD Powered Plug‑Ins library.
This sleek 1U rackmount processor is available in two bundled plug‑in configurations:
UAD-2 Live Rack Core – Includes a generous suite of UAD plug‑ins, including legendary
1176 and Teletronix LA‑2A compressors, and Pultec EQs.
UAD-2 Live Rack Ultimate – Includes over 90 UAD plug‑ins, with exclusive titles from
SSL®, Studer,® SSL,® Neve,® Manley,® Lexicon,® API,® Fender,® Moog,® and many
more.
Included with both UAD‑2 Live Rack configurations is the Antares Auto‑Tune Realtime
plug‑in. Legendary for its vocal enhancing and creative applications, genuine Antares
Auto‑Tuning can be used in real time for pitch correction and modern pop vocal effects.
And existing UAD plug‑in users can readily use their licensed UAD plug‑ins with UAD‑2
Live Rack.
Note: A small number of UAD plug-ins are incompatible with UAD-2 Live Rack.
For full details, visit help.uaudio.com.
Live Rack Application
With the Live Rack application, front‑of‑house engineers can take advantage of intuitive
features such as drag and drop, copy and paste, keyboard navigation, plug‑in zoom, and
the ability to store and recall channel strip presets and/or complete setup configuration
Snapshots. Designed for seamless operation in a live setting, the Live Rack app features
large text and GUI elements making it easy to quickly tweak parameters.
The Live Rack app also features MIDI snapshot recall capabilities as well as networked
software integration with select Soundcraft Vi consoles.
Fail-Safe Features
UAD‑2 Live Rack includes professional, fail‑safe features for reliable live sound use.
Redundant internal power supplies ensure that UAD‑2 Live Rack will continue to process
audio if one power supply fails. If the Live Rack application or computer fails, or its
Thunderbolt cable is disconnected, UAD‑2 Live Rack will still process audio with the last
known plug‑in state intact. And with the Live Rack app in Safe mode, destructive setting
changes are prevented during a live show.

UAD‑2 Live Rack has several components that comprise the complete UAD‑2 Live Rack
system. A brief description of each component is provided below, along with a link to
complete details about the component.
UAD-2 Live Rack Hardware
The UAD‑2 Live Rack unit is the 1U rack hardware that performs audio signal processing
on digital audio streams via MADI. The hardware unit contains four SHARC DSPs that
process the UAD Powered Plug‑In algorithms. Each unit can process up to 16 MADI
streams, and up to four units can be combined to process a total of 64 MADI streams.
The UAD‑2 Live Rack hardware is configured and controlled by the UAD‑2 Live Rack
software application.
For complete hardware details, see “Chapter 2: Hardware” beginning on page 19.
Live Rack Software Application
The Live Rack application is the software interface for the UAD‑2 Live Rack hardware
unit. The software configures and controls the hardware unit(s) and UAD Powered Plug‑
Ins. The application runs on select Mac computers and it interfaces to the UAD‑2 Live
Rack hardware via Thunderbolt.
Note: Although UAD Powered Plug-Ins are operated via the Live Rack software,
the signal processing is performed on the hardware unit’s SHARC DSP, not the
computer’s CPU.
For complete details about the software application, see “Chapter 4: Live Rack
Application” beginning on page 39.
UAD Powered Plug-Ins
UAD Powered Plug‑Ins are software plug‑in titles containing DSP algorithms. UAD plug‑
ins are loaded and controlled within the Live Rack software for signal processing on
the four SHARC DSPs in the UAD‑2 Live Rack hardware. Each UAD plug‑in contains a
graphical user interface (GUI) and various control parameters that can be manipulated to
achieve the desired sonic results.
Typical UAD plug-in interface
UAD Powered Plug‑Ins are developed by Universal Audio and also by Direct Developer
(3rd‑party) partners. A wide range of titles are available that are suitable for nearly every
application. The UAD Powered Plug‑In titles that are included with UAD‑2 Live Rack
depend on the bundle included with the retail product package:
UAD‑2 Live Rack Manual Chapter 1: Introduction 15
Core Live – The Core Live bundle includes 15 UAD plug‑in titles that were selected as a
fundamental base set for live sound applications.
Ultimate Live 2 – The Ultimate Live 2 bundle includes 84 UA‑developed titles. Note that
Direct Developer titles are not included.
UAD plug‑ins that are not included in the retail bundles are optional and purchased
separately. Optional UAD plug‑ins can be individually evaluated without functional
limitations for 14 days in demo mode, and can be purchased anytime at the UA store at
www.uaudio.com.
For complete details about how UAD Powered Plug‑Ins are used within UAD‑2 Live Rack,
see “Chapter 6: Using UAD Plug‑Ins” beginning on page 133. For complete details
about individual UAD Powered Plug‑Ins, see the UAD Plug‑Ins Manual which is placed
on the startup disk during software installation.
Note: UAD-2 Live Rack, like other UAD devices, can only use UAD Powered PlugIns which are developed specifically for the UAD DSP accelerator platform. Plugins developed for other hosts and platforms (VST, RTAS, AAX, Audio Units, native,
etc) cannot be used with the UAD-2 Live Rack system.
UAD Meter & Control Panel Software Application
The UAD Meter & Control Panel is used to authorize licensed UAD plug‑ins and configure
global functionality that pertains to all UAD devices in the same system (the application
is used for all UAD products).
The application consists of two components: The UAD Meter and the UAD Control
Panels. Complete documentation for the UAD Meter & Control Panel application is in
“Chapter 5: UAD Meter & Control Panel” beginning on page 120.
UAD Meter
The UAD Meter window (shown at right) displays the
current DSP and memory status of all active UAD‑2 Live
Rack hardware (including multiple devices).
Note: These meters are also represented within the UAD-2 Live Rack application.
UAD Control Panels
The UAD Control Panel window has multiple panels that
display, and enable control of, various UAD system, plug‑
in, and global configuration parameters.
The screenshot at right shows the System Info panel, one
of four control panel windows in the UAD Meter & Control
Panel application.
UAD‑2 Live Rack Manual Chapter 1: Introduction 16
UA Store
The UA store at www.uaudio.com is where optional UAD plug‑in licenses can be
purchased. Promotional coupons are also redeemed here. All UAD device registrations
and plug‑in authorizations are managed here as well.
For complete details, see “Chapter 7: UA Account & Store” beginning on page 140.
Soundcraft Vi Series Consoles
Note: UAD-2 Live Rack can be used with any compatible MADI system.
Soundcraft Vi Series consoles are digital mixing/processing systems designed for use in a
live sound environment.
UAD‑2 Live Rack includes Vi console integration. Vi consoles integrate with UAD‑2 Live
Rack via two simultaneous control protocols:
MADI – Digital audio streams are routed between Vi consoles and the UAD‑2 Live Rack
hardware unit for signal processing via MADI optical I/O (note that all UAD plug‑in
signals are processed in the UAD‑2 Live Rack hardware unit, not in the Vi console). Use
the Vi Console’s powerful Insert and patching system to route signals to and from the Vi
console via MADI.
Ethernet – Digital control signals, for saving and loading UAD‑2 Live Rack configuration
Snapshots (Vi CUEs), are routed between Vi consoles and the Mac computer running
UAD‑2 Live Rack software via Ethernet.
Soundcraft Realtime Rack
Soundcraft Realtime Rack was designed
and manufactured by Universal Audio, but
sold and distributed through Soundcraft by
Harman.
Realtime Rack is functionally similar to UAD‑2 Live Rack. The main difference between
the two is that Realtime Rack has Thunderbolt 2 ports (some earliest units have
Thunderbolt 1 ports), while UAD‑2 Live Rack has Thunderbolt 3 ports. UAD‑2 Live
Rack software can be used with Realtime Rack, and Realtime Rack can be combined
with UAD‑2 Live Rack in multi‑unit systems with appropriate Thunderbolt adapters and
cabling.

Hardware Overview
The UAD‑2 Live Rack hardware is the 1U rack device that performs audio signal
processing on digital audio streams via MADI optical I/O. The hardware unit contains four
SHARC DSPs that process the UAD Powered Plug‑In algorithms. Each unit can process
up to 16 MADI streams, and up to four units can be combined to process a total of 64
MADI streams. Additionally, each unit has dual‑redundant internal power supplies and
automatic failover protection.
Each UAD‑2 Live Rack hardware unit is configured and controlled by the UAD‑2 Live
Rack software application. The MADI channels being processed by each hardware unit is
specified in the Settings tab in the UAD‑2 Live Rack software.
Front Panel
This section describes the function of all visual indicators and controls on the UAD‑2
Live Rack front panel. There are five visual‑only elements and one recessed hardware
RESET button.

and properly communicating with, the Mac computer that is running UAD‑2 Live Rack
software.
The UAD‑2 Live Rack software must be properly installed and configured on the host
computer to enable driver connectivity, and the HOST indicator must be illuminated to
use UAD‑2 Live Rack with all computer and Vi console operations.
UAD‑2 Live Rack Manual Chapter 2: Hardware 19
(2) PSU Indicators
These indicators display the status of the rear panel dual redundant internal power
supply units (PSU). There is one indicator for each power supply unit (PSU 1 and PSU
2). The color of each indicator displays the status of the PSU as follows:
White – The PSU is operating normally. The PSU is connected to AC power, and the
power switch for the PSU (rear panel) is in the ON position.
Red – The PSU is not delivering power. This state is caused by one or more of the
following conditions:
• The PSU is not connected to AC power
• The power switch for the PSU is in the OFF position
• The PSU has malfunctioned
PSU Indicator notes:
• If one internal power supply unit fails, UAD‑2 Live Rack will continue to process
audio signals.
• It is normal for the PSU indicator to flash red upon power up of the hardware
(3) POWER Indicator
The Universal Audio text and logo are lit when the hardware unit is receiving proper
operating voltages from one or both internal power supply units.
(4 & 5) MADI Indicators
These indicators represent whether or not MADI digital audio signals are present at the
rear panel MADI I/O connectors. There is one indicator for MADI input and one for MADI
output. The state of each indicator represents the MADI signals as follows:
White (bright) – The audio level of any channel in the MADI stream is above ‑60 dB.
White (dim) – The MADI stream is detected but no channels are above ‑60 dB.
Black (off) – No audio signals are present in the MADI stream.
(4) MADI IN Indicator
Indicates the state of digital audio signals at the rear panel MADI input connector.
(5) MADI OUT Indicator
Indicates the state of digital audio signals at the rear panel MADI output connector.

(3) Thunderbolt 3 Ports
Connect a Thunderbolt cable (not included) between one of these ports and the
Thunderbolt 3 port on the Mac host computer that is running the UAD‑2 Live Rack
software application. The HOST indicator on the front panel is lit when the connection is
established.
Either port can be used for the host computer connection. The other port remains
available for Thunderbolt 3 daisy‑chain connections, for example additional UAD‑2 Live
Rack units or the Apple Thunderbolt 3 to Gigabit Ethernet Adapter.
Note: Although Thunderbolt 3 always uses USB-C connectors, not all USB-C
computer ports are Thunderbolt 3 ports.
(4) Word Clock Out
This BNC connector transmits a standard (1x) word clock when UAD‑2 Live Rack is set
to use its internal clock. The clock rate sent by this port matches the current system
sample rate, as specified in the Hardware tab within the UAD‑2 Live Rack software
application.
When UAD‑2 Live Rack is set to use external word clock as its clock, UAD‑2 Live Rack
is a word clock slave. If the incoming external word clock is within ±0.5% of a supported
sample rate (44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz), Word Clock Out will mirror Word
Clock In with a slight phase delay of about 40 nanoseconds.
UAD‑2 Live Rack Manual Chapter 2: Hardware 22
(5) Word Clock In
UAD‑2 Live Rack’s internal clock can be synchronized (slaved) to an external master
word clock. This is accomplished by setting UAD‑2 Live Rack’s clock source to Word
Clock in the Hardware tab within the UAD‑2 Live Rack software’s Settings view,
connecting the external word clock’s BNC connector to UAD‑2 Live Rack’s word clock
input, and setting the external device to transmit word clock. If UAD‑2 Live Rack is the
last device in the clock chain, the Termination switch (6) should be engaged.
Note: UAD-2 Live Rack can be synchronized to an external “1x” clock signal only.
Superclock, overclocking, and subclocking are not supported.
(6) Word Clock Termination Switch
This pushbutton switch provides internal 75‑ohm word clock input signal termination
when required. Word clock termination is active when the switch is engaged (depressed).
UAD‑2 Live Rack’s termination switch should only be engaged when UAD‑2 Live Rack
is set to sync to external word clock and it is the last device at the receiving end of a
word clock cable. For example, if UAD‑2 Live Rack is the last “slave” unit at the end
of a clock chain (when UAD‑2 Live Rack’s word clock out port is not used), termination
should be active.
(7) 1394b Ports (no function)
The 1394b ports are for manufacturing purposes only. They have no functionality within
the UAD‑2 Live Rack system.
Important: Do not attach any devices, including a computer, to the 1394b ports.
(8 & 9) MADI I/O Ports
The MADI I/O ports are used for the digital audio interconnections between the UAD‑2
Live Rack hardware unit and other MADI equipment. Dual Optical SC‑Plug (ISO/IEC
9314‑3) connectors are provided.
(8) MADI OUT
Connect this port to the MADI optical input on the MADI device.
(9) MADI IN
Connect this port to the MADI optical output on the MADI device.
UAD‑2 Live Rack Manual Chapter 2: Hardware 23
Standalone Behavior
UAD‑2 Live Rack supports limited standalone functionality in the event that the
Thunderbolt 3 connection to the host computer is lost, or if the UAD‑2 Live Rack
hardware unit is power cycled and no host computer is found upon re‑powering the
hardware.
Thunderbolt 3 connection lost – In the event that the Thunderbolt 3 cable is removed at
one or both ends, or if the host computer is otherwise no longer detected, UAD‑2 Live
Rack will continue to process audio in the same state as when the connection was lost,
including UAD plug‑in processing. If/when the host connection is reestablished, the
UAD‑2 Live Rack software will be updated to reflect the current state of the hardware,
and software control is resumed.
Important: Reestablishing the Thunderbolt 3 host-to-hardware connection will
cause a temporary mute of the audio streams as channels and plug-ins are reallocated. In the event of a mid-show failure, wait until it is acceptable to hear a
mute in the audio path (e.g., not in the middle of a song).
Power cycled, no host found – In the event that power to the UAD‑2 Live Rack hardware
unit is completely interrupted then reestablished and/or the unit is manually power
cycled or reset, and the host computer cannot be detected after re‑powering the
hardware, UAD‑2 Live Rack will function in “all MADI inputs to all MADI outputs” mode
without UAD plug‑in processing. This ensures that audio can still be routed by the Vi
console, even if the UAD‑2 Live Rack software connection cannot be established.

Vi-Series Console Connection Notes
• The HiQnet port on early Vi1 consoles (serial numbers lower than 30210956) is
only able to drive short cable lengths, with a maximum recommended length 1
meter (3 feet). Therefore, use a network switch positioned close to the rear of the
console to extend the cable length if required with these early Vi1 consoles.
• The HiQnet port on other Vi consoles is capable of driving standard Ethernet
distances of up to 100 meters.
• The HiQnet port uses the same 8P8C modular connector as the Dante™ ports
available on Vi consoles. Connect to the HiQnet port only.
Connect UAD-2 Live Rack to the HiQnet port
• Macs with Thunderbolt 1 or Thunderbolt 2 ports can be used with additional
adapters. For details, see "Thunderbolt 1 and 2 Mac Wiring" on page 28.
• Interconnect the UAD‑2 Live Rack hardware unit, the Live Rack software host
computer, and the SoundCraft Vi‑series console following the illustrations on the
