AXIA

NETWORKING

Devices equipped with Livewire interfaces (like the latest Telos

Zephyrs and phone hybrids, Omnia audio processors, AudioSci-

ence cards and IDC satellite receivers, for example) supply audio

and control logic directly from the device to the Ethernet switch

over a single CAT-5e connection, further simplifying in-studio

wiring and making Livewire’s audio+logic routing even more

convenient.

DO I HAVE TO BE AN IT EXPERT TO RUN AN AXIA SYSTEM?

An IP-Audio network is like a car: you don’t have to understand

how the engine works in order to drive it. Just connect two pieces

of gear together with CAT-5e and they will talk to each other —

like plugging a mic into a mixer. The Livewire protocol takes care

of routing the audio without any need for intervention from you.

And the equipment interface is all web-based with GUI control.

It works intuitively, and you don’t have to know anything about

the tech inside to make it work. Axia consoles even include built-

in, zero-conﬁguration network switches — no network switch

setup needed.

That having been said, another of the advantages of Ethernet

and IP is that it’s well-documented. Telos founder Steve Church

and technologist Skip Pizzi have even collaborated on a book

published by Focal Press, Audio Over IP: Building Pro AoIP Sys-

tems With Livewire. It’s available from all the usual booksellers,

and as an eBook as well.

MOST COMPANIES RECOMMEND THAT I BRING THEM ON-SITE

TO HELP INSTALL AND CONFIGURE THEIR SYSTEMS. DO I NEED

YOUR HELP TO INSTALL AN AXIA SYSTEM?

With those other guys, you’d better hire their systems engi-

neers. With us, it’s much easier! If you know how to use a Web

browser and plug a telephone into the wall, you’ve got all the

skills needed to install and conﬁgure your new Axia network. And

Axia Technical Support is there to help if you need it, too. If you

still decide you’d like on-site installation services, we’ll be happy

to talk with you about it.

WHAT ABOUT PROGRAM ASSOCIATED DATA? IS YOUR SYSTEM

COMPATIBLE?

Yes. Devices that generate PAD plug into the Axia network; the

information they supply is sent along with its associated audio,

and any devices that need it can also plug into the network

and retrieve it. This means that you can send audio and PAD

together, without incurring extra costs for separate audio and

data networks.

IS LIVEWIRE AUDIO COMPRESSED, OR LINEAR?

Livewire is not compressed. Axia xNodes produce linear 48 kHz,

24-bit studio-grade audio, and there are switches that have

enough bandwidth to carry 10,000+ channels of uncompressed,

real-time stereo audio simultaneously.

IF I USE xNODES TO BUILD AN AXIA ROUTING NETWORK, DO I

HAVE TO USE AXIA CONSOLES?

Not necessarily. Axia networks can work with your existing con-

soles — just plug the inputs and outputs into the xNodes and

add our XY Controllers for route switching. For sophisticated

systems, use our PathﬁnderPC router control software package.

You can do everything any other router can do – and much more.

Of course, if you do decide to use Axia consoles, you’ll have the

advantage of features like automatic mix-minus on every chan-

nel, the ability to control Telos phone systems and codecs right

from the mixing board, the option to use integrated Intercom

systems with broadcast-quality audio, and even the ability to

remotely-control your console from another room – or even off-

site. And setup is simple — the built-in network switch inside

Axia integrated console engines lets you daisy-chain up to 4 con-

soles together without the need for an external switch.

CAN THE NETWORK BE USED FOR GENERAL DATA TRAFFIC AS

WELL AS AUDIO?

Most certainly, should you choose to do so. The Ethernet switch

naturally isolates trafﬁc. You may even use one link for both

audio and data, since the audio is prioritized. This will probably

be the case when a PC is connected to the network — you will

sometimes want to download ﬁles, receive e-mail, etc., in addi-

tion to the audio stuff.

I’VE GOT A LARGE FACILITY. HOW MANY STUDIOS CAN I INTER-

CONNECT?

There is no practical limit. You may have as many studios and

audio channels as your Ethernet switch can support. Switches

come in all sizes, some with hundreds of ports. And multiple

switches may be cascaded to expand ports.

I HAVE A LOT OF MONO SOURCES AT MY FACILITY. CAN xNODES

HANDLE MONO SOURCES, OR ARE THEY STRICTLY STEREO?

Like all Axia gear, xNodes give you plenty of choices. You can run

an Analog or AES xNode in stereo mode, generating 4 channels

of stereo input and 4 channels of stereo output, or mono mode,

with 8 channels in and out.

THIS SOUNDS PRETTY SOPHISTICATED. WHAT ABOUT FOR

SMALLER STATIONS?

Look at Ethernet for data applications. You have everything from

a few PCs in a small ofﬁce to huge campus networks with thou-

sands of nodes. This is one of the reasons we went with Ethernet

- you can use it for big and small facilities. The technology and

economics naturally scale to suit the application size. We ﬁgure,

in fact, that small stations may beneﬁt the most as they gain

routing capability at a very modest cost.

And, should you choose to use Axia consoles, it gets even sim-

pler, thanks to the onboard, zero-conﬁguration network switch
