War of the Waves
Dear Valued Customer,
It’s with great pride and a tip of the hat to an incredible team that I congratulate you on your new Telos Alliance
product. Everything we do here at the radio division of the Telos Alliance is with one end goal in mind: To help
broadcasters declare victory in extremely competitive environments. By purchasing this product from us, in
essence, you have declared war on your competition.
After all, the majority of Telos Alliance employees were broadcasters themselves once, and the products we’ve
developed over the years have been designed as solutions to specific issues faced on the front lines of our industry.
We’re right there in the trenches with you and have the weapons you need in your arsenal.
Telos Systems is a catalyst to out-of-this-world sound, with the most powerful and popular broadcast telephone
systems in the industry; IP/ISDN codecs and transceivers; plus processing/encoding for streaming audio. We built
an industry on the back of these amazing telephony systems, and they are still going strong.
While we at the Telos Alliance never forget our roots, we are also blazing trails in terms of new technologies like
stream-encoding and AoIP, so that all types of broadcasters can excel in this ever-evolving digital world.
Omnia Audio not only lets you stand out on the dial with your unique signature sound via legendary audio
processors, audio codecs, and microphone processing, it lets you give your listeners a better streaming experience

About This Manual
Read Me. Please. (OK, at least read some of me.)
If you’re like many engineers or IT types, you’ve probably already put your brand new R/2 into the rack, connected
power, connected the network, and perhaps even connected some audio. You may have even powered it up and
figured out how to set an IP address to access the web GUI. If that’s you…Great! You’re a few steps ahead of the
game and we hope this manual can provide some additional valuable information for you.
If that’s totally not you and you’re more of a “by the book” kind of person, that’s great too. We hope you’ve at least
gone through the included Quick Start Guide and found it helpful. This manual will cover some of the same basics
as the Quick Start Guide, and go into great detail about how to get your R/2 up and running.
The layout of this manual is pretty straightforward…It should be in the order you would normally perform
installation and configuration steps for the most part (though there may be a few little rabbit trails). The author
has tried to take a “what would someone trying to set this up for the first time need to know, and in what order”
approach. Some of the chapters dealing with audio processing setup or other configuration details will be a bit
longer than others, but overall this manual should be a pretty quick read.
We realize reading manuals isn’t everyone’s idea of a great time, but we’ll try at least to keep it informative and
somewhat entertaining—though the author has a habit of cracking some pretty bad jokes. If you aren’t asleep by the
end of it, and have your R/2 up and running, this manual has accomplished its goal.
There are probably a lot of things you could be doing with your time besides reading a manual, and we appreciate
that you’ve taken the time to read this one. If you REALLY don’t have time to read anything else, start with chapters 3
through 7. Chapter 8 is probably the longest in the manual, but covers how to actually make R/2 start doing stuff. If
you’re in even more of a hurry, jump straight to the Frequently Asked Questions at the end of this manual (Chapter 16).
If after reading this manual you have any suggestions for improvement (or if you see something we might have
missed) send a note to [email protected].
As always, our support team is available 24/7 to assist by calling 216-622-0247 or e-mail [email protected].
The world is listening. Stream like you mean it.

1 So what is Z/IPStream R/2?
A Bit of History
It started with the telephone…
For over 30 years, Telos has led the industry in telephony and audio encoding technology for broadcast. When
Steve Church developed the first digital telephone hybrid for broadcast in 1984, it was the beginning of a revolution
in how the industry would get audio from the field on the air. Telephone calls had never sounded so good.
MP3 and ISDN
This revolution continued with the introduction of the Telos Zephyr ISDN codec in 1993. It was the first codec to
make use of the (then relatively new) MPEG Layer III codec to send full 20 kHz mono audio across a single 56 or 64
kbps data channel. Broadcasters could finally bring full fidelity audio to their listeners from the field (or between
facilities) without dedicated equalized program loops or RF links. The Zephyr quickly became the de-facto
industry standard for ISDN codecs, used by studios around the globe for transporting audio.
SECTION 1 | 1

SECTION 1 | 2
SO WHAT IS Z/IPSTREAM R/2?
Streaming…It begins.
While ISDN was becoming popular for broadcasters to transport audio from the field or between facilities, the next
frontier was exploring new methods for getting audio to the listeners. The Internet was still in its infancy, but it had
developed to the point where streaming audio (even over dialup) was becoming viable. In 1997, Telos introduced
the very first dedicated hardware encoder for MP3 streaming over the Internet, simplifying what was a bit of a
cumbersome process and dramatically improving the audio quality.
Omnia: A Legend in Audio Processing for Broadcast
During this same period of time, Frank Foti was working tirelessly to improve the sound of audio processing
for broadcast. His dial-dominating innovations in audio processing at Z100 were the foundation of what would
ultimately become Omnia. The audio processing developments didn’t stop at the FM dial, however…It quickly
became apparent that there was considerable benefit to be gained from specialized audio processing for streaming
as well.
Telos Encoding + Omnia Processing = Z/IPStream
As streaming continued to gain in popularity, the demand for an “all in one” solution to handle both processing and
encoding for streams grew tremendously. In 2009, Omnia launched the A/XE software package, combining the
best of Telos encoding technology with 3-band Omnia audio processing tailored specifically for streaming. In 2012,
Telos introduced R/1, a new hardware appliance designed specifically for stream processing and encoding without
a dedicated PC.

SECTION 1 | 3
SO WHAT IS Z/IPSTREAM R/2?
The Z/IPStream family gained yet another powerful option with the availability of acclaimed Omnia.9 processing
in 9X/2 streaming software. Z/IPStream represents the latest in encoding and audio processing developments from
The Telos Alliance, and supports a wide variety of streaming technologies including adaptive bitrate streaming for
a seamless listener experience regardless of network conditions, or listening platform.

2 A Few Words about Livewire+ and AES67
What is Livewire+™ ?
Livewire+ is the pioneering technology invented by the Telos Alliance to convey low-delay, high-reliability audio
over switched Ethernet.
Introduced as Livewire™ in 2003, today’s Livewire+ is AES67-compliant. That means that it complies fully with
the AES67-2013 Interoperability Standard, allowing AES67 devices to connect directly to Livewire+ networks
and exchange audio streams. Livewire+ is also extensible, able to incorporate future AES standards when they are
ratified. Livewire+ is also backward-compatible with the RAVENNA™ networking protocol.
With Livewire+, a single Ethernet cable carries real-time uncompressed digital audio, device control messages,
program associated data, and even routine network traffic. An entire facility can be wired in hours, instead of
weeks. All Axia Audio studio products, and most products from other Telos Alliance brands, utilize Livewire+
networking technology. Expanding or modifying your system is simple thanks to the inherent scalability and
modularity of Livewire+.
Livewire+ offers a revolutionary change in how studios can be built. But at the same time, it’s a natural continuation
of general trends and what you already know.
SECTION 2 | 2

SECTION 2 | 3
A FEW WORDS ABOUT LIVEWIRE+ AND AES67
How Livewire+ works
Livewire+ has an audio advertising system. Every source has a text name and numeric ID. These are transmitted
from source devices to the network. Devices that play audio build lists of all available sources from which users can
select.
UsingxNode audio interfaces, you enter the names of your input sources via any PC with a web browser.
Withplayout PCs attached to the network, you open a configuration window.
Livewire+ networks employ two types of audio streams.Livestreamshave small, frequent packets optimized
for live audio that requires very low (circa1 ms.) delay, for microphones and headphone audio.Standard
Streamsare also real-time streams, but with bigger packets, and are used for audio streams which don’t require
super-low latency - like audio from CD players, or that exchanged with automation system PCs. Devices that
connect to Axia networks can transmit and receive both stream types; the user selects which type to generate when
a device is initially configured.
A sophisticated phase-locked loop clocking system allows Livewire+ to use very small buffers for least latency
and ensures that audio channels remain time-aligned (as needed for multiple mics in a studio or for TV sur-
round-sound mixing.)
Converged Networks
An Ethernet network used for Livewire+ audio can also be shared with other data transmissions, such as file
transfers and web browsing. An Ethernet system with a switch at the center may have a mix of audio nodes and
normal servers, PCs, etc., because the Ethernet switch directs traffic only to where it is needed.
Even on a single link, traffic can be mixed because we use modern Ethernet’s priority mechanism to be sure audio
packets have first call on the link’s bandwidth. A studio audio delivery system can use this capability to download
an audio file from a server, for example, while simultaneously playing another audio file live.
Livewire+ maximizes the benefits of converged networking in the broadcast facility. Many stations using Livewire+
have computer data, telephone, audio, and control on a single network that uses computer industry standard
wiring, spurring cost-efficiencies throughout the plant.
Audio Quality
A Livewire+ network is a controlled, high-speed environment, with no risk of audio drop-outs from network
problems and plenty of bandwidth for many channels of high-quality uncompressed audio. We use studio-grade
48kHz/24-bit PCM encoding. Axia digital xNode audio adapters deliver 138dB of dynamic range, with less than
0.0002% THD. Even analog xNodes have 100dB dynamic range, < 0.005% THD, and headroom to +24dBu.
Livewire+ is standards-based
Since the very beginning, The Telos Alliance has based its AoIP networking technologies on standards. IP (Internet
Protocol), the networking standard that is the underpinning of nearly all critical business networks (and of the
Internet itself) is the basis for Livewire+ AoIP.
As charter members of the AES X.192 Working Group, we helped define the AES67 standard — and became the
first broadcast manufacturer to become AES67 compliant.
Livewire+ is so standards-based, in fact, that your audio can even be played by PC media playersthat support
standard protocols and uncompressed PCM audio. The Internet’s IP standard for streaming media, called RTP/IP,
is used for standard audio streams. RTP stands for Real-Time Protocol. It’s the Internet’s standard way to transport
streaming audio and video, just as TCP/IP is the standard for general data.

SECTION 2 | 4
A FEW WORDS ABOUT LIVEWIRE+ AND AES67
The Gold Standard
In the decade since the introduction of Livewire+, broadcasters have adopted it at an exponential rate; AoIP has
become the new standard for broadcast facilities.
Consider these facts:
♦There are over 6,000 studios worldwide built with Livewire+.
♦More than 5,500 networked Axia consoles are at work daily.
♦Over 80 Livewire+ Partner companies provide compatible hardware and software products.
♦There are more than 60,000 individual Livewire+ devices in the field.
♦Livewire+ is fully compliant with the AES67 Interoperability Standard.
Impressive, no? But there are even more exciting things in the future. The Telos Alliance, with one of the largest
R&D groups in broadcast, is fully committed to AoIP interoperability. We’ve been proponents of open standards
since Day 1, freely sharing our technology with interested Hardware and Software Partners. We were charter,
supporting member of the X.192 Working Group that defined the AES67 standard, and as founding members
of the Media Networking Allliance, are actively engaged in work to promote and enhance standards-based AoIP
networking.

3 Installation
Physical Considerations
Rack Mounting
R/2 includes a pair of rack rails designed to secure the unit to the rear of the equipment rack. It is highly recom-
mended that you install these rails if possible due to the depth of the unit. Mounting by the front panel alone
may cause excessive strain on the chassis and is not recommended. The supplied rails should fit in most standard
equipment racks, but if installing the rails is not possible, you may wish to consider placing an upside-down rack
shelf underneath the unit for additional physical support.
Airow
As with most rackmount server chassis, the airflow on R/2 is from front to back. While it is not absolutely neces-
sary to leave an additional rack space above and below the unit, it certainly is not a bad idea if the space is available.
Do not block the front panel of R/2 behind a solid rack door.
Wiring Management
Since airflow is from front to back, it is important to keep the rear of the unit free from obstructions to allow for hot
air exhaust. Install the wiring in such a way that it allows for a reasonable service loop and does not block airflow.
Do not allow wiring from other equipment in the rack to block airflow from the rear panel of R/2.
Rear Panel
SECTION 3 | 5

SECTION 3 | 6
INSTALLATION
Power
The R/2 is equipped with dual power supplies (120V – 240V, 50 – 60Hz) to allow for facilities with redundant
power feeds to the equipment racks from separate sources. An LED on the supply will indicate the presence of AC
power and proper operation. If power is lost on one of the AC inputs or one of the supplies should fail, the R/2
will sound an alarm. The only way to mute this alarm is to connect power to both supplies or (in the case of power
supply failure) remove the failed supply.
Note:
If only one of the two power supplies is connected, an alarm will sound. Connect both supplies to
AC power, even if you don’t have redundant AC power feeds to the equipment rack.
RS-232
Not currently implemented. Inserting stream metadata via RS-232 will be supported in a future release. See chapter
10 (Metadata Sources and Filters) for more details about stream metadata.
“Control”Ethernet Port
This port (if populated) is intended for out-of-band system management. Not currently implemented.
USB Ports
Future expansion or factory service. Not currently implemented.
NIC 1 and NIC 2
The R/2 offers dual network adapters. Typically, one adapter (NIC1) would be used for Audio over IP, while the
second (NIC2) would be dedicated to streaming audio traffic. Either interface can be used for management via the
web GUI. Connect your network(s) to NIC 1 and/or NIC 2. Do not connect both interfaces to the same network.
Doing so may cause routing and connectivity issues.
Note:
Do not connect both interfaces to the same network simultaneously. Routing and connectivity
issues may result. Ensure each interface is connected to a dierent IP network, (dierent VLAN,
physical switch, IP address block, etc.) as necessary. Consult your IT department or Telos technical
support if you are not sure how the interfaces should be congured. Only one interface may be
needed in some rare cases.

SECTION 3 | 7
INSTALLATION
VGA
Factory service only. Not currently implemented.
Audio (AES/EBU)
Eight AES/EBU audio connections are available through two high-density 26-pin D-sub connectors. Connect the
provided breakout cable(s) to the D-sub connectors. Use the thumbscrews to securely attach the cables in place.
Sample rate conversion is provided on all inputs. The BNC Word Clock connectors are not currently implement-
ed. Each audio channel can be configured to generate a stream at 44.1 or 48 kHz (see Chapter 7: Audio Source
Configuration).

Power Up
Press the “On/Off” button located on the right half of the front panel to power up the unit (See Chapter 4 for a full
front panel description). During the power up process, the front panel will light up and display a splash screen. If
the display remains dark and fans do not spin up, verify that AC power is present at both power supply inputs.
If the fans spin up but the display remains dark or does not show a splash screen, contact support.

SECTION 3 | 9
INSTALLATION
Fans
The fans in R/2 are thermostatically controlled. As the unit powers up, the fans will start at full speed. They should
spin down to a much slower speed after a short period of time. If they do not return to low speed, it may indicate a
faulty fan or other hardware issue. During normal operation, these fans may increase in speed if the unit’s internal
temperature rises. If the fans remain at full speed during operation and the environmental temperature of the unit
appears normal, contact support.
Note:
The fans will run at full speed for a brief period of time during boot. They should return to a relatively
moderate speed within a short period of time. If the fans remain at full speed, it may indicate a
hardware fault. Slightly higher fan speed during operation is normal if the internal temperature of
the unit increases.
Input Level Meters
Once the unit has fully booted, the front panel LCD will display the input audio level meter screen. As of software
version 1.0.34, these meters can display either AES or Livewire input levels by using the up and down navigation
arrows on the front panel.
Livewire and other Audio over IP input sources (as well as output level metering and processing metering) can
also be metered via the unit’s web GUI or via NfRemote for Omnia.9 processing (See Chapter 16 for Omnia.9
processing information).
Note:
Select between Livewire or AES input levels by using the up and down navigation arrows from this
screen (see chapter 7 for information about dening audio sources). Metering can also be accessed
from within the web GUI or NfRemote software (if using Omnia.9 processing).
