Important Safety Information
To prevent risk of electric shock: Disconnect power
cord before servicing. If fuse replacement is required,
please note: For continued protection against fire, replace fuse only with same type and value.
Caution
The installation and servicing instructions in the
manual are for use by qualified personnel only. To
avoid Electric Shock, do not perform any servicing
other than that contained in the operating instructions unless you are qualified to do so. Refer all servicing to qualified personnel.
Electrical Warning
To reduce the risk of electrical shock, do not expose
this product to rain or moisture. Keep liquids away
from the ventilation openings in the top and rear of
the unit. Do not shower or bathe with the unit.
This equipment is designed to be operated from
a power source that includes a third “grounding”
connection in addition to the power leads. Do not
defeat this safety feature. In addition to creating a
potentially hazardous situation, defeating this safety
ground will prevent the internal line noise filter from
functioning.
Ventilation Warning
The Axia StudioEngine and Power Supply/GPIO
Nodes use convection cooling. Do not block the
ventilation openings in the top and rear of the unit.
SmartEngine and the PowerSupply/GPIO Node
must be mounted with a blank rack spacer above or
damage may occur.
Failure to allow proper ventilation could damage the
unit or create a fire hazard. Do not place the unit on
a carpet, bedding, or other materials that could interfere with the side and top panel ventilation openings.

It’s been a tradition since Telos’ very first product, the
Telos 10 digital phone system, that I share a few words
with you at the beginning of each manual. So here goes.
In radio broadcast studios we’re still picking up the
pieces that have fallen out from the digital audio revolution. We’re not using cart machines anymore because
PCs are so clearly a better way to store and play audio.
We’re replacing our analog mixing consoles with digital
ones and routing audio digitally. But we’re still using
decades-old analog or primitive digital methods to connect our gear. Livewire has been developed by Telos to
provide a modern PC and computer network-oriented
way to connect and distribute professional audio around
a broadcast studio facility.
Your question may be, “Why Telos? Don’t you guys
make phone stuff?” Yes, we certainly do. But we’ve always been attracted to new and better ways
to make things happen in radio facilities. And
we’ve always looked for opportunities to
make networks of all kinds work for broadcasters. When DSP was first possible, we used
it to fix the ages-old phone hybrid problem. It
was the first use of DSP in radio broadcasting.
When ISDN and MP3 first happened, we saw
the possibility to make a truly useful codec. We were the
first to license and use MP3 and the first to incorporate
ISDN into a codec. We were active in the early days of
internet audio, and the first to use MP3 on the internet.
Inventing and adapting new technologies for broadcast
is what we’ve always been about. And we’ve always
been marrying audio with networks. It’s been our passion right from the start. In our genes, if you will. As a
pioneer in broadcast digital audio and DSP, we’ve grown
an R&D team with a lot of creative guys who are openeyed to new ideas. So it’s actually quite natural that we
would be playing marriage broker to computer networks
and studio audio.
What you get from this is nearly as hot as a couple
on their wedding night: On one RJ-45, two-way multiple
audio channels, sophisticated control and data capability, and built-in computer compatibility. You can use
Livewire as a simple sound card replacement – an audio
interface connecting to a PC with an RJ-45 cable. But
add an Ethernet switch and more interfaces to build a
system with as many inputs and outputs as you want.
Audio may be routed directly from interface to interface or to other PCs, so you now have an audio routing
system that does everything a traditional “mainframe”
audio router does – but at a lot lower cost and with a lot
more capability. Add real-time mixing/processing engines and control surfaces and you have a modern studio
facility with many advantages over the old ways of doing
things. OK, maybe this is not as thrilling as a wedding
night – perhaps kissing your first lover is a better analogy. (By the way, and way off-topic, did you know that
the person you were kissing was 72.8% water?)
While we’re on the subject of history… you’ve probably been soldering XLRs for a long time, so you feel a
bit, shall we say, “attached” to them. We understand. But
no problem – you’ll be needing them for microphones
for a long while, so your withdrawal symptoms won’t be
serious. But your facility already has plenty
of Ethernet and plenty of computers, so you
probably already know your way around an
RJ-45 as well. It’s really not that strange to
imagine live audio flowing over computer networks, and there’s little question that you are
going to be seeing a lot of it in the coming
years.
The 20th century was remarkable for its tremendous
innovation in machines of all kinds: power generators,
heating and air conditioning, cars, airplanes, factory automation, radio, TV, computers. At the dawn of the 21st,
it’s clear that the ongoing digitization and networking of
text, audio, and images will be a main technology story
for decades to come, and an exciting ride for those of us
fortunate to be in the thick of it.
Speaking of years, it has been a lot of them since
I wrote the Zephyr manual intro, and even more since
the Telos 10 – 20 years now. Amazing thing is, with all
the change around us, I’m still here and Telos is still
growing in new ways. As, no doubt, are you and your
stations.

A Note From The Founder/CEO of Telos
Introduction • viii
A Note From The President of Axia
20 years ago, I designed my first broadcast console
for PR&E. I look back on that time with great fondness;
we were building bullet-proof boards for the world’s
most prestigious broadcasters, making each new console
design bigger and fancier to accommodate a wider variety of source equipment and programming styles. The
console was the core of the studio; all other equipment
was on the periphery.
Then things changed: the PC found its way into
broadcast audio delivery and production. At first, PC
audio applications were simple, used only by budget
stations to reduce operating expenses. But soon the applications evolved and were embraced by larger stations.
Slowly, the PC was taking center stage in the radio studio.
Like many, I was captivated by the PC. Stations
retired carts, phonographs, open-reel decks,
cassettes — even more modern digital equipment such as DAT and CD players, replacing all with PC apps. Client/server systems
emerged and entire facilities began using PCs
to provide most – or all – of their recorded
audio. Yet consoles continued to treat PCs as
nothing more than audio peripherals. I knew
that we console designers were going to have to rethink
our designs to deal with computer-centric studios.
During this time, traditional broadcast console companies began producing digital versions. But early digital consoles were nearly identical in form and function
to their analog predecessors. It took a fresh look from a
European company outside broadcasting to merge two
products – audio routing switchers and broadcast consoles – into a central processing engine and attached
control surface. Eventually nearly every console and
routing switcher company followed suit, and a wide variety of digital “engines” and control surfaces flooded
the market.
But, advanced as these integrated systems were, they
still handled computer-based audio sources like their
analog ancestors. Sure, the router and console engine
were now integrated, but the most important studio element – the PC – was stuck in the past, interfaced with
100-year-old analog technology. The PC and console
couldn’t communicate in a meaningful way – strange,
considering that PCs everywhere were being networked,
fast becoming the world’s most popular and powerful
communication tool.
Then a group of Telos engineers developed a method
of using Ethernet to network real-time audio devices, allowing computers and consoles, controllers and peripherals to interact smoothly and intelligently. Powerful, flexible networks had finally come to our studios. As with
the transition from carts to computers, the benefits are
many and impressive. A few networked components can
replace routing switchers, consoles, processing peripherals, sound cards, distribution amps, selector switches
and myriad related devices.
This deceptively simple networked system costs a
fraction of other approaches, yet has capabilities surpassing anything else. The system is modular and can
be used to perform discrete functions in a traditional
environment. Concurrently, it easily scales to
serve both the humblest and the very largest
of facilities. Console, router, and computer
work in harmony.
So, equipped with this new technology
and countless ideas, we launch Axia, the newest division of Telos. Axia is all about delivering innovative networked audio products
to future-minded broadcasters. On behalf of our entire
team, I welcome you as a charter client. Axia is the culmination of nearly 40 man-years of some of the most
ambitious R&D ever applied to the radio industry. And
this is only the beginning. We have more products, innovations, and partnerships in the pipeline.
You already know your Axia system is unlike anything else. So it shouldn’t be surprising that your new
system is loaded with new thinking, new approaches,
and new ideas in virtually every conceivable area. Some
concepts will challenge your traditional ideas of studio
audio systems, but we’re certain that once you have experienced the pleasures of the networked studio, you’ll
never want to go back. And now, for something completely different...

You’ve probably unpacked your boxes and are sitting
next to a pile of Axia gear, wondering what to do first.
Take a look at the diagram above: it represents a typical Livewire-connected radio studio. Here’s what you
should do to get going:
1. Using CAT.5e or CAT.6 Ethernet cable, connect
all of your Axia Audio Nodes (Analog, AES/EBU,
Microphone and Router Selector) to 100Base-T
ports on your studio’s Ethernet switch.
2. Use CAT.6 Ethernet cable to connect your
StudioEngine to a Gigabit (1000Base-T) port on
the switch.
3. Use another CAT.5e or CAT.6 cable to connect
the Ethernet port on the back of SmartSurface to
a 100Base-T port on the switch.
When you’ve completed physically connecting your Axia hardware, read
through the remainder of this manual to begin configuring the software options that determine how your new
SmartSurface will operate.

Introduction
There’s nothing quite as much fun as taking something new out of its box. That sense of excitement as
all the protective packaging is stripped away; that “new
gear” smell… it’s exhilarating!
If you’re reading this, there’s a 99.9794% chance
that you’ve done just that, and are now sitting in the
middle of a room surrounded by packing material and
a large wooden crate, admiring your new SmartSurface,
its GPIO Node/Power Supply and StudioEngine — and
wondering what to do next.
The purpose of this chapter is to provide you with
clear, concise instructions to get you up and running.
(First, of course, we recommend you read the Introduction to Livewire: System Design Reference and Primer,
available from www.AxiaAudio.com.) We’ll install the
SmartSurface first, followed by the StudioEngine.
Be Prepared
Important note: Axia strongly recommends
that SmartSurface be the final peripheral installed in any studio.
Because so much of the SmartSurface configuration process depends upon having access to
audio sources and destinations previously defined, you must connect and configure your
other Axia peripherals (Audio Nodes, GPIO
Nodes, Router Selectors, etc.) prior to configuring SmartSurface, according to the instructions
supplied with each.
To install SmartSurface, prepare a cutout in your
studio counter top (a full-size dimensional drawing is
included with your SmartSurface for your cabinet provider’s use. There’s also a scaled-down version with all
pertinent measurements in this manual’s Appendix).
Double-check to ensure adequate clearance for the re-
Before beginning any part of your studio configuration, determine a range of IP addresses to assign to each
studio and log each device’s IP as you assign it; the appendix also contains an IP Assignment Worksheet you
can use for this purpose. IP addresses used in an Axia
network must be valid Unicast IP addresses. Determine
your network’s subnet mask settings at the same time
(typically this value is set at 255.255.255.0 for intranet
applications).
Unicast vs. Multicast IP Addresses: Data
is routed over IP networks in one of two ways:
point-to-point unicast or multicast.
Livewire devices use common TCP/IP unicast
IP addresses for control and web browser access. These are numbers you assign within
the range used by your network. Since most
Livewire networks are not intended to be accessed via the Internet, we recommend you use
the non-routable IP addresses in the range of
192.168.0.0 to 192.168.255.255. These IP addresses have been set aside for use with local
networks, when it isn’t necessary (or even desirable, for security reasons) to use a public IP
address.
Multicast allows efficient one-to-many connections, so Livewire uses that for its audio streams,
source advertising, and synchronization signals.
You do not need to assign these multicast addresses because the system does this automatically.
For more information on network construction,
please refer to our companion Introduction to
Livewire: System Design Reference and Primer
available at www.AxiaAudio.com/downloads/ .
To configure SmartSurface, you’ll need a computer.
Any Windows desktop or notebook PC with an Ethernet
port and a standard Internet browser is acceptable.
For cable connections, CAT. 6 Ethernet cable is
required. Axia strongly recommends shielded CAT.6,
such as Belden MediaTwist or similar high-performance
bonded cable if your studio design calls for cable runs
through areas containing high levels of RF. (For greater
detail on cable selections, read The Axia Guide to Choosing Category Cable, from www.AxiaAudio.com/tech/.)

quired cable connections and grounding stud; the connection panel is in the center rear of the unit.
Always make certain that power has been applied to
your studio’s Ethernet switch before powering any other
Axia components.
SmartSurface Preliminary Setup
If you haven’t done so yet, it’s time to get your
SmartSurface out of its packing crate.
Important: Like any electronic device,
SmartSurface can be affected by static electricity. Use of a personal grounding device is
strongly recommended during installation.
Position one person at each end of SmartSurface
and, grasping the metal enclosure at the bottom, simultaneously lift upward out of the shipping crate. Remove
packing materials and store them in the crate for future
use.
Carefully lower SmartSurface into the cutout in your
studio counter top. Be mindful of the connector panel
located in the center rear of the electronics enclosure;
take care not to catch the grounding stud on the counter
top edge or damage may occur.
Unpack the GPIO Node/Power Supply that came
with your SmartSurface and place it in the rack.
Connections and IP Configuration
1: Setup & Connections • 2
Connections
Cable connections for SmartSurface are entirely dif-
ferent from any other mixing surface you may be familiar with. There are no audio inputs; SmartSurface needs
only power and Ethernet connections to operate.
1. Rack-mount the GPIO Node/Power Supply unit and
connect it to a 100Base-T port on your studio’s Ethernet switch using CAT. 6 cable. Do not power up the
Power Supply yet.
2. Route another length of CAT. 6 from your
SmartSurface to the switch, but do not connect it yet
— we’ll do that later.
3. SmartSurface must be connected to a grounded
metal, permanent wiring system or other equipment
grounding conductor using the threaded grounding
stud located on the connections panel. For ground
sources, we recommend, in order of preference:
» “Station Ground,” the heavy copper strap running
through the walls and floors of many radio studios.
» AC Safety Ground — the “3rd prong” of a nearby
outlet.
» A bonded electrical conduit.
#12 AWG GREEN stranded wire is the minimum
wire gauge acceptable for grounding SmartSurface.
Important: Your SmartSurface MUST be
grounded. Grounding reduces the risk of electric shock by providing a “path of least resistance” for electric current. Improper grounding can result in a risk of electric shock. Check
with a qualified electrician if you are in doubt
about how to properly ground this equipment.
If your local electrical code prohibits the use of
a Station Ground for this purpose, as described
Figure 1-1: SmartSurface Connection Panel
©2005 Axia Audio — Rev. 1.07
4. Use the 5-pin XLR cable provided to connect the
GPIO Node/Power Supply to the SmartSurface connector labeled “DC INPUT 1.” (Note that there are
two power inputs to accommodate redundant power
supplies should you wish to equip your studio with
this option.)
5. Whew, that was hard work. Better have a beer.
IP Address Configuration
Using your IP Assignment Worksheet, you’ll now
choose an IP address for both your SmartSurface and
StudioEngine. You must make sure that IP addresses
for both Engine and Surface are in the same IP network,
and are both valid Unicast addresses. For example:
»
»
192.168.2.101: Engine
192.168.2.201: Surface
Both addresses belong to 192.168.2.x IP network,
and so will work for our application.
Note: “Gateway” settings on Livewire equipment are optional. They may be left blank unless you intend to access the StudioEngine’s
configuration utility remotely, from outside your
network. Should you desire to do so, enter the
IP address of your master router (the one with
external network connections) whenever you’re
given the option to enter a gateway IP address.
Once you’ve determined the IP addresses you’ll assign, power on the SmartSurface power supply.
When SmartSurface has completed its start cycle
(meter screens appear), push and hold the Control Op-
key located at the bottom of the center section,
then push and hold all three Talk To keys located just
below the meter screens. You must hold these keys for
five seconds to enter the IP Setup screen (Figure 1-2).
tions
Notice that the legend beneath the third Monitor volume control is now blinking NET CONFIG. Push the
knob once; you’ll see a box appear onscreen around the
first value, marked SmartSurface IP Address. Push
the knob again and the box turns solid; rotate the knob
to set the desired value. Push the knob to “take” the new
value, then turn it to select the next hex value. Repeat the
process until you’re entered the desired IP address, then
do the same to set your subnet mask value.
Continue down the screen and set the appropriate
values for your network gateway (optional, if you wish
to remotely administer your system from offsite), and
your chosen NTP (Network Time Protocol) server. The
Phone Server IP Address field is reserved for use with
Telos broadcast telephone systems with IP connectivity.
Note that the last option on this setup screen allows you to set a password for HTTP administration
of SmartSurface; you may enter any string of standard
ASCII characters, from 1 – 12 characters in length. If
you leave this option undefined, you will not need to enter a password to access SmartSurface options via Web
browser.
Connect the Ethernet cable from your SmartSurface
to any 100Base-T port on the switch. Proceed to the next
section to set up your StudioEngine.

above, use the specific “Safety Ground” your local regulations mandate.
We also recommend leaving 1RU of “breathing
space” for ventilation above and below the Studio Engine when you rack-mount the unit.
1. Using the supplied AC power cord, connect the
SmartEngine to the mains, but do not switch the unit
on at this time.
2. Route a length of CAT. 6 cable from SmartEngine to
a Gigabit (1000Base-T) port on your studio’s Ethernet switch. Do not connect the Ethernet cable to your
SmartEngine yet; we’ll do that after we assign its IP
address.
IP Configuration
1. Power on your StudioEngine; the front-panel display
will indicate the boot-up sequence. When the screen
displays IP address and network connection information, push the control knob to call the Main Menu.
2. Turn the control knob right to scroll to the tab marked
EID (“Engine ID”, Figure 1-3), and push to select.

3. Push the control knob and you’ll see that the first
line of the display, marked IP Addr is underlined.
Push the knob again to select this line.
4. You’ll see a flashing underline under the first digit
of the IP address. Push and rotate the control knob
to select the value for this digit. Push again to “take”
the value.
5. Continue this sequence until your IP address is
properly entered. When finished, turn the control
knob until the check mark at the end of the line is
highlighted, and push the knob to apply the new IP
value.
6. When you’ve set the subnet mask and gateway IP
address (optional), choose OK at the bottom of the
screen.
7. You’ll be asked if you’d like to reboot for changes
to take effect. select YES. While your StudioEngine
reboots, connect its Ethernet cable.
8. After reboot, navigate to the tab marked SID. If your
StudioEngine is running software version 2.3.27
or higher,, and your SmartSurface is running version 2.4.9 or higher, the IP address of your studio’s
SmartSurface will be displayed here. Confirm the IP
address, then turn the control knob until the X symbol is selected and push.
StudioEngine Channel Settings
For the next steps we’ll be using the StudioEngine’s
HTTP interface, so connect a computer loaded with
an Internet browser to the local switch. This computer
should have an IP address in the same range assigned to
the SmartSurface and StudioEngine.
Note: Axia web interfaces are tested for use
with Microsoft Internet Explorer, version 5 and
later, and Firefox version 1,00 and later, but
may also work with other browsers. Whatever
browser you choose, Java must be enabled and
your pop-up blocker, if any, must be disabled in
order to work with Axia equipment.
In a Livewire network, individual devices (audio
nodes, studio controllers, etc.) are identified by unique
IP addresses. But what about the audio streams these
devices generate? Think about how many audio sources
and destinations there are in even a small studio — there
are a lot to keep track of.
In the analog days, we’d affix a numbered label to
each cable that entered the terminal room to identify
each audio circuit. Obviously, we can’t attach pieces of
paper to digital packet streams, but we can give each
one a “label.”
We refer to these “labels” as Network Channel Numbers. Each Livewire system can support 32,766 channels
of audio, which enables us to give each audio source or
destination its own unique numeric channel number.
Note: We’ve observed that 32,000+ channel numbers exceeds the average human’s
RAM storage capacity. We recommend using a
spreadsheet program — just to make sure you

As soon as you connected your StudioEngine to the
network (following the steps in the previous section), it
began to generate audio using factory default channel
numbers. To avoid conflict with other studios, we’ll need
to change those default values to new channel numbers.
Note: When you’ve constructed custom Show
Profiles, you can use this dropdown box to specify which saved profile to use when SmartSurface
starts. Since radio studios are generally 24-hour
operations, the profile you specify here should

your facilities. If you choose “Restore Previous State,” the surface will boot the console
to exactly the state it was in prior to shutdown.

Configuring Inputs
In this chapter we’ll discuss how to set up inputs for
your SmartSurface. We’ll be using the HTTP servers
built into the SmartSurface and SmartEngine to do this.
Note: Axia web interfaces have been tested with
Microsoft Internet Explorer, version 5 or later,
but also work with other browsers.
We also like Mozilla’s FireFox browser, especially
wit regards to its “tabbed browsing” capabilities.
With tabbed browsing, it’s possible to bookmark the IP addressees of entire rooms worth of
Audio Nodes, then recall them in tabbed groups
with a single click.
Whatever browser you choose, Java must be enabled and your pop-up blocker, if any, must be
disabled in order to work with Axia equipment.
Understanding Source Profiles
One of the most repetitive and tedious parts of studio
building has always been tying “data” to audio sources.
Consider the wiring of line selector modules: you need
a cable for the remote audio source, a set of wires for a
“start” closure, another set for “stop” — even with TDM
routers, an operation as seemingly simple as logic-follows-audio often turns out to be not so simple.
Mix-minus and IFB generation is also a problem.
Too often it’s a complicated process that requires air talent to correctly determine source and bus assignments at
a moment’s notice. How many times has unwanted audio
made air thanks to this error-prone procedure?
SmartSurface eliminates these headaches by letting
you merge audio, logic and program data into a single,
routable information stream. Since audio in a Livewire
network is transported as packetized data, it’s easy for
us to “piggyback” other data along with audio. This is
accomplished through the use of Source Profiles.
To understand how Source Profiles work, think of
In a Livewire network, a Source Profile works much
the same way, aggregating all information about a given
source into one tidy package, so that the audio (payload) is transported by the network (delivery system),
accompanied by control definitions, source type information and PAD (program associated data) which allow
SmartSurface to automatically generate and send associated backfeeds and mix-minuses, determine monitor
settings and enable remote-control device logic.
The result of all this is that each SmartSurface on
your network is always presented with complete, consistent information about how you want a given audio
source handled, so that it’s treated the same way no matter what studio it’s used in.
Note also that with SmartSurface, it is possible to
create more than one Source Profile for a single audio
source — one with logic enabled, and one without, for
instance, or one with preset EQ and one without. This
allows you unparalleled flexibility in tailoring operational capabilities to your air talent’s needs.
Source Profile Setup
Now that you understand what Source Profiles
do, let’s set one up. You’ll use the SmartSurface and
StudioEngine HTTP interface to do this, so connect a
computer loaded with an Internet browser to the local
switch.
Note: You can’t configure SmartSurface I/O unless you’ve already connected inputs and outputs to your studio’s Audio Nodes. Make sure
you’ve done this before proceeding through this
chapter.
Your computer must be assigned a valid network IP
address in order to “see” Livewire web pages. Livewire
networks don’t contain DHCP servers, so you must
manually assign your computer an IP address within the

Chapter Two:
a sandwich: the meat is the “payload” and the bread its
“delivery system,” and other “associated data” (cheese)
comes along for the ride.
Note: While 10 characters are available for labeling sources, we recommend using eight or
fewer characters whenever possible. This practice provides each SmartSurface fader’s alphanumeric display a “buffer zones” between it and
its neighbor, keeping source labels from “running together” and ensuring legibility.

systems use different methods to do this; please consult
your OS’s documentation for specific instructions. Note
also that your studio’s Audio Nodes and sources must be
configured prior to defining source profiles.

1. Enter the IP address of your SmartSurface in your
computer’s Web browser. A login screen will prompt
you for a password. If you set a password during
SmartSurface initial setup, enter it now; otherwise
leave the field blank and click OK.
2. Choose the Source profiles menu item from the
main screen, and click the New Source Profile link
at the bottom of the screen. You’re now in the Source
Profile creation screen.
The three final check boxes, CR monitor input, CR
headphone input and Studio monitor input determine whether the board op will be able to assign
this source to the monitor and headphone busses.
To prevent a source from appearing on the monitor
headphone selection lists, uncheck the desired box.

AVAILABILITY: These check boxes
determine which faders you’ll allow this source
to be assigned to. For example, if your source is
a Control Room mic, and you only want it to appear on the first left-hand fader, you would check
only the box marked Channel 1. You might
want to make a CD player available on any fader, so you’d check the boxes for all 16 channels.
Some sources – especially air monitors – you’d
wish to prevent from ever being assigned to a fader,

Feeds:
SmartSurface provides you with several headphone options. The Guest headphone output
provides a standard headphone feed of the
source assigned to the studio headphone feed.
The Talent headphone output feeds this same
audio, but includes a global talkback channel
that the host or board op can use to communicate with talent only using the Talk To Studio function (and that guests do not hear).
An individual headphone feed can also be constructed to associate a dedicated headphone
channel with a specific mic. This allows the
board op to send individual, targeted talkback to
a specific individual (using the Talk To Preview
function) without other talent or guests hearing.
Finally, a unique host headphone feed is associated with control room board operator mics
only, and includes headphone monitoring of the
Preview bus and other special functions.

About SmartSurface EQ: Equalization is available for all audio sources, and can be pre-defined or adjusted on-the-fly. Our EQ model is
three-band quasi-parametric. Controls are provided for center frequency and boost/cut, with a
unique SmartQ™ automatic bandwidth system.
SmartQ works by varying the Q of the selected
parametric band proportional to the amount of
boost or cut you specify. A small amount of boost
or cut will affect a broader range of frequencies
for a warm, musically-pleasing effect. As gain is
increased the Q sharpens, affecting a narrower
range of frequencies for tighter control of target
bands. At aggressive cut levels, the EQ becomes a
tunable notch filter. SmartQ keeps the EQ sounding natural at virtually all settings.
SIGNAL MODE LOCK: Allows or disallows user’s
ability to change the source’s signal mode (as set
above) using the “Channel Options” menu on the
SmartSurface.
» Unlocked allows the user to change modes if
needed.
» Locked prevents changes to the signal mode.
Allows for correction of out-ofphase program material.
» Normal assumes correct phase polarity of source
input material.
» Invert left reverses phase on the left channel
input.
» Invert right reverses phase on the right channel
input.
» Invert left and right reverses phase on both
channel inputs.
Pre-defined EQ can be entered during Source
Profile construction, and will be automatically
applied whenever that source is assigned to a
SmartSurface fader; i.e., a -2 dB 12 kHz high
shelf filter pre-set in a microphone’s Source
Profile will be applied when any surface, in
any studio, loads that mic for use.
At-will EQ is set by talent using SmartSurface’s
Channel Options controls, and can be employed to trim EQ on-the-fly .

77. You’ve just constructed a Source Profile for it, and
you now want to give it a mix-minus backfeed and set up
a GPIO contact closure for the “take” and “drop” functions. Here’s how:
1. Make sure that the Source Profile for your hybrid has
Source Type set to “Phone” Backward Feed “Enabled”. Leave Feed to Source Mode set to “Auto”.
2. Use your Web browser to connect with the Audio
Node you’ll be sending your backfeed to. Choose
Destinations from the main menu to enter the Destinations screen (Figure 2-2); since our source was
on input #7 of this Node, we’ll set up our mix-minus
for output #7.
3. Just to the right of each Channel name box , you’ll
see a “list” icon. Click on the list icon for output #7.
A list of available sources will pop up (Figure 2-3).
Notice that the names and channel numbers of the
sources are both displayed for easy identification.
We’ll choose Hybrid from the list.; the list window
closes and you’re returned to the Destinations
screen. The line for output #7 now displays the channel number and name of the source.
4. Now comes the step that makes this output a mixminus. Each Destination entry line has a drop box
at the end; click on the drop-down and choose To
source (Livestream).
Note: For a detailed description of these options
and how they operate, please refer to the 8x8
Analog Node / 8x8 AES Node User’s Manual.
5. Click Apply.
6. Now point your browser to your GPIO Node and
choose GPIO from the main menu.
7. The GPIO setup screen uses the same method of assigning devices to ports as the Analog Node. Pick a
port to map your hybrid’s contact closures to, using
the list tool, and click Apply.
The process is complete: you’ve made a Source Profile for your hybrid, created a mix-minus, mapped it to
an Analog Node audio output, and associated a GPIO
contact closure with the source.
To confirm, choose the Options key at the top of any

to a Source Profile
SmartSurface fader channel and load your new source;
you’ll see the Status Symbols appear in the window
above the channel to indicate that SmartSurface is backfeeding a mix-minus to this telephone hybrid. (Status
Symbols are described in detail at the end of Chapter
Four, “SmartSurface Operations.)
Also, take another look at the GPIO screen on
your browser. Note the green indicators that have appeared on the port representing your hybrid; switch the

When you’re ready, join us in Chapter Three for more

for your audio sources. 

Configuring GPIO
Since the earliest days of simple, rotary-switch
source selectors, it’s always been a challenge to properly
route machine logic along with audio. Some complicated schemes have been devised over the years, but still
broadcasters keep asking for a simple, fast way to associate logic with audio in a routable environment.
Since the Axia IP-Audio system was designed as a
true computer network, we were able to start with a fresh
sheet of paper to design the first truly routable machine
logic/audio interface. Unlike conventional logic connections, which require each command circuit to be wired
individually, Axia sends machine controls over the same
Ethernet on which your studio’s audio travels, further reducing infrastructure, cost and tedium.
Along with controlling external audio devices, SmartSurface’s GPIO interface also includes logic commands
for routine studio/control room operations such as tally
lights, monitor muting, On-Air lights and more.
This chapter will explain how to set up a SmartSurface
GPIO to handle these functions. (We assume you’ve already read the GPIO Node User’s Manual, familiarized
yourself with its controls, and assigned it an IP. If not,
we strongly recommend you do so, as this chapter is not
designed to be a comprehensive primer.)
Note: Some GPIO Nodes also contain power
supplies for SmartSurface studio control surfaces. We recommend that, when rack-mounting
these units, you leave 1RU of space above and
below the GPIO Node/Power Supply to ensure
adequate ventilation.
GPIO Port Definitions
GPIO ports are programmed to support eight different types of devices. How does a GPIO port “know”
which type of device is assigned to it? Well, there’s a
little bit of magic involved.
Back in Chapter Two, when you constructed a Source
Profile for a telephone hybrid, you defined the source
type (see “Adding Backfeeds and GPIO to a Source Profile,” p. 8). This is important, because when a GPIO
port is assigned to a source, the GPIO Node looks at this
Source Profile parameter to determine what logic functions the assigned port should provide.
So, if the GPIO “sees” in the Source Profile that the
assigned device is a microphone, it provides logic for
On, Off, Remote Mute and Remote Talk commands. If
it “sees” a line input defined in the Source Profile, it provides Start, Stop and Reset commands, plus Ready
lights, etc.,
Earlier we mentioned that a GPIO port can deliver
eight different command sets. These are:
1.
2.
3.

POWER & COMMON
Assigning GPIO to a Source
As you’ve seen by studying the previous pages, a lot
of the work of assigning logic to a source is done for you;
once a GPIO port is linked with a physical audio source,
all that’s left is to solder cables connecting the GPIO’s
DB-15 connectors to the device’s control interface.
3. If you haven’t previously assigned any GPIO ports,
the GPIO definitions screen will be blank, as shown
in Figure 3-3. Notice the status indicators at the top
of the page, showing the state of the input and output
pins of each port. Click on the list icon to the right
of an unused line.
So, how do you link a GPIO port with an audio
source? It’s very easy; let’s do it step-by-step.
Note: This procedure assumes that you have
set up at least one audio source according to
instructions from your Axia Audio Node manual.
1. Open your Web browser and enter the IP address of
a GPIO Node connected to your system.
Figure 3-4: Channel box and list icon.
4. When you click on any list icon, a small popup window will open (Figure 3-5), enumerating all of the
audio sources available on the Livewire network.
Choose the source you wish to associate with a GPIO
port by clicking on it; the window will close and the
source’s name and channel number will appear in
the Channel box.

2. When the GPIO main menu opens, click GPIO to
open the GPIO definitions page. You will receive a
login prompt (the default login is “user”; leave the
password field blank).
Figure 3-5: GPIO Select Source popup list
5. Type a descriptive name in the Name field, and click
on the Apply button at the bottom of the page.

link to a SmartSurface channel; operate the ON and
OFF keys for the channel and watch the pin status
indicators for Port 1 change as you do so.
The source we’ve been using for this demonstration is a telephone hybrid; we can now observe the
pin status indicators change as we turn the channel
on and off, as shown in Figure 3-5.
Figure 3-5: Pin status indicators showing
GPIO port activity
Referring to the Hybrid Logic Chart on Page 19,
we can see that when the SmartSurface channel is
Off, the indicator representing Output Pin 2 – the
Off Lamp logic command – is high. Turning the
channel On, we see Pin 4 pulse briefly before Pin 1
goes high: the GPIO has just sent a Start pulse, then
lit the On Lamp. If you turn the channel Off again,
you’ll observe a Stop pulse, and the Off Lamp command once again become active.
See how easy that was? Simply assigning an existing
audio source to a GPIO port automagically configures
the port for the type of device supplying the audio, and
sends the appropriate logic commands to that port when
the source is assigned to a SmartSurface channel.
When you’re ready, join us in Chapter Four for a
comprehensive walk-through of SmartSurface operations. 

SmartSurface Operations
Once it’s installed in your studio, SmartSurface looks
a lot like a traditional radio broadcast console — but
that’s where the resemblance ends.
SmartSurface isn’t a console; it doesn’t actually mix
or process audio. It would be more accurate to say that
SmartSurface is a control center, allowing the operator
to take charge of the delivery system, the StudioEngine
mixing/routing engine, the phone system, the recorder/
editor and other sources.
With SmartSurface, our goal is to provide you with
the most efficient man-machine interface possible for
fast-paced, complex programs where board operators
must multi-task without error. As such, SmartSurface
brings a whole new level of control and sophistication
to the broadcast studio, while providing very intuitive
operation.
Overview
SmartSurface was designed to perform equally well
in air or production studios. In the air studio, the clean
interface enhances speed and accuracy without clutter
or confusing controls. In the production room, deeper
levels of sophistication are accessible with the touch of
a button.
Because different people work differently, we’ve
made it possible to access various functions in multiple
ways. By providing several paths to access a function,
the board operator has less to remember and is less likely to get trapped. This also serves to bring new operators
up to speed easily. One of the most powerful tools on the
SmartSurface is the “Soft Key” section in the middle of
the board. These context-sensitive buttons and associated text display change dynamically, following the operator through various tasks.
Displays
Dual active matrix TFT (thin-film transistor) displays constantly give operators status and configuration
information. These displays normally show meter levels
for PGM-1, PGM-2, the time of day clock and the event
timer, as well as important status messages. When the
operator adjusts console options, the right screen is used
to help navigate the options, which are mirrored on the
Soft Keys for fast access to the presented functions.
Show Profiles
SmartSurface can be completely reconfigured, instantly, to suit different types of shows. By using predefined Show Profiles, talent can change board settings
from a phone and microphone intensive morning show
to a personality-based music show at the touch of a button.
Show Profiles are easily accessed through software
by pressing the Control Options button above the scrub
wheel, the Soft Keys then allow instant access to stored
Show Profiles and other settings. Construction and administration of Show Profiles is covered in Chapter Five.
“Show Profiles.”
Sources and Channels
During the course of this manual, we’ll refer often to
sources and channels. These are not the same! “Sources” are microphones, CD players, outputs from the
playout system, telephone hybrids, etc. Your Livewire
network may have a very large number of sources, in
different locations, used at various times.
“Channel” usually refers to the individual
SmartSurface faders and their on/off controls, alpha displays, bus assignment keys, etc. “Channel” is also used
when discussing numbered Livewire network streams.
To avoid confusion, we’ll call them “Surface Channels
and “Network Channels” where appropriate.
©2005 Axia Audio — Rev 1.07

Chapter Four:
In this chapter we’ll first give you a high-level overview of SmartSurface capabilities to help convey exactly
what SmartSurface is capable of. Then, we’ll give you
detailed explanations of the various controls and functions.
Sources are assigned to surface channels for use onair or in production. During initial configuration, the
sources are programmed by the engineer for appropriate logic and options (as outlined in previous chapters);
afterwards, whenever that source is assigned to a surface
channel, source logic follows.
Surface channel settings are instantly reconfigured whenever a source is selected, to accommodate
the unique requirements of the source. For example, a
surface channel controlling a microphone source also
controls appropriate monitor mutes. A surface channel
controlling a line source sends “start” and “stop” commands when the channel is turned on and off.
Sources can also be fed directly to the monitors for
auditioning without being assigned to a surface channel.
Mix-Minus
Mix-minus setup, especially for live broadcasts, has
always been one of the most confusing aspects of running a radio board.
4: SmartSurface Operations • 28
SmartSurface makes mix-minus easy by automating it. The operator never has to worry about sending a
source back to itself — it just can’t happen!
Several mix-minus choices – fixed and switching
– are possible, and are configured for each source when
Source Profiles are defined by the engineer (see Chapter Two for details). Once this setup is done, no further
tweaking is needed; the operator simply uses the source.
A Status Symbol display on each surface channel tells
operators when a particular source has a mix minus
output, and even tells them which audio mix is being
backfed.
SmartSurface can accommodate up to 16 phone and/
or codec inputs at a time, each with its own automated
mix minus feed.
GPIO
As explained in Chapter Three, each input source
can have associated GPIO (General Purpose Input/Output) control associated with it. SmartSurface GPIO in-
terfaces are connected to SmartSurface via the Livewire
network, so you can locate the actual machine connections either physically close to source equipment or in a
central equipment room.
During installation, the engineer configures sources to accept and provide logic commands by selecting
various options. Example: studio microphones may be
set up to automatically mute the studio monitor speakers and illuminate an on-air warning light when turned
on. The same sources can be configured to accept GPIO
logic inputs from buttons so each studio guest can have
their own On, Off, Talk, and Mute keys (see Chapter
One, “Setup and Configuration” for details ).
Line sources can be configured to receive start and
stop commands from the SmartSurface as well. Start/
stop messages can also be passed, via Ethernet, to a
computer-based playout system.
Soft Keys and Scrub Wheel
The Soft Keys in the center section, with their alphanumeric displays, work in conjunction with the display
screens to give board ops quick access to menu functions. The scrub wheel can be used to control monitor or
headphone volume.
Software
The SmartSurface operating system uses a high-performance embedded Linux kernel to help ensure bulletproof, 24/7 operation. Software updates, when available,
can be obtained from Axia Audio via the Internet and
applied by the station engineer.
Updating system software will not affect Show Profiles or other configuration data already programmed
into the system.

(start and stop pulses, monitor muting, etc.) appropriate
to the selected source.
Now, let’s see what happens when specific types of
sources are assigned to a fader channel.
©2005 Axia Audio — Rev. 1.07
Source-Specific Channel Controls
As mentioned previously, some fader-channel functions change their behavior to suit the specific type of
source assigned to the fader. An Operator’s mic input
has unique functions different from those of a Codec input, and so forth. In this section we’ll explain the channel functions unique to each type of source input.
Operator Microphone Channel Operation
The Operator microphone is the board operator’s
mic. It’s always located in the Control Room, so activating a channel designated as the Operator mic will affect
the muting of the CR monitor speakers and the Preview
speakers.
When the board operator pushes a Talk to Studio
or Talk to Previewed Source key, all output bus assignments for the Operator microphone are temporarily
muted, while his mic’s audio is routed to the requested
Talk to... destination. When the button is released, the
channel outputs return to normal.
the Talk to Preview key routes the operator’s microphone to any source(s) in Preview mode. For example,
the board op can talk to a caller’s mix-minus feed by
placing the caller’s channel in Preview mode and pushing the Talk to Preview key. (Since this channel is configured to be a host microphone, placing this channel in
Preview and hitting Talk to Preview will do nothing.)
Depressing the channel On key for the Operator Mic
while the channel is already on will cause the channel
to mute until the button is released, acting as a “cough”
function for the board operator. On-air status and speaker mutes are unaffected by this action.
The Operator microphone channel will mute the
Control Room speakers and the Preview speakers whenever the channel is On, or if Preview or Record keys
are selected. If only the Phone key is selected, the Control Room speakers will mute independently, leaving the
Preview speakers un-muted.
The block diagram for this channel selection is
shown in Figure 4-8.
A powerful Talk to Preview function is provided
for the board operator using the Operator mic. Pressing

Control Room Guest Microphone Channel Operation
There are often microphones in the Control Room
other than the board operator’s; i.e., an in-studio guest
wing, or perhaps a producer or announcer located physically near the board op. These microphones control the
muting of the Control Room monitor speakers.
The Control Room monitor speakers and Preview
speakers will mute when this channel is turned on, or
when Preview or Record are selected. The Control
Room speakers will also be muted when this channel is
assigned to the Phone bus.
Control Room Guest mics can be turned on and off
remotely, and provide on/off status to a remote logic
device. Remote Talk and Remote Mute functions are
also provided, and can be activated using a remote On/
Off/Talk/Mute panel.
Remote Talk lets talent and guests communicate
with the board operator. When Talk is remotely activated on a CR Guest mic channel, outputs to program
buses for that channel are muted and the mic audio is fed
to the Talkback bus. While this is active, the Preview
key will be lit and the Status Symbol will display the
word TALK. When the user stops talking, the channel
returns to normal, and its Preview key flashes for three
seconds, alerting the board operator to the guest who
spoke to him, and enabling him to reply using the Talk
to Previewed Source key.
When the Remote Mute function is activated, the
Status Symbol displays MUTE, and all the channel outputs are muted until the command is released.
Control Room Guest Microphone channels will mute
the Control Room speakers and the Preview speakers
whenever the channel is On, or if Preview or Record
keys are selected. If only the Phone key is selected, the
Control Room speakers will mute independently, leaving the Preview speakers un-muted.
Finally, Control Room Guest Microphone channels
have provisions for an individual Headphone feed. This
is especially useful for talent and guests in the same
room as the board operator; their headphone feeds will
all monitor the audio selected on the Studio Monitor
selector, but the board op can communicate with each
person privately using Talk To Previewed Source.
The block diagram for this channel selection is
shown in Figure 4-9.

Control Room Producer Microphone
Channel Operation
The third type of microphone channel available
with SmartSurface is the Control Room Producer Microphone. This mic type is intended for show producers
who contribute to program content and are located in
the control room. so activating a Producer mic channel
affects the muting of the CR monitor speakers and the
Preview speakers.
Associated GPIO outputs support several functions
that can be controlled from a producer’s remote panel.
Producer mics can be turned on and off remotely, and
provide on/off status to a remote logic device. Remote
Talk and Remote Mute functions are also provided,
as well as two remote talkback functions. CR Producer
mics may also use the Talk to Studio and Talk to Previewed Source functions previously described in the
“Operator Microphone Channel Operation” section of
this chapter.
allows a producer, located in the Control Room, to talk to Studio guests or previewed sources
with associated backfeeds. When Talk to Studio or
Talk to Previewed Source is remotely activated on a
CR Producer mic channel, outputs to program buses for
that channel are muted and the mic audio is fed to the
Talkback bus. While this is active, the Preview key will
be lit and the Status Symbol will display the word TALK.
When these functions are no longer active, the channel
outputs return to normal.

When the Remote Mute function is activated, the
Status Symbol displays MUTE, and all the channel outputs are muted until the command is released.

Studio Guest Microphone Channel Operation
The fourth type of microphone channel available
with SmartSurface is a Studio Guest Microphone. This
mic is typically located in a location separate from the
control room — perhaps a voice-over booth, a talk studio separated by glass, or a news booth.
Logic for Studio Guest Microphone channels is
identical to that of the Control Room Guest Microphone
channel. Studio Guest Microphone channels can be
turned on and off remotely and will provide on/off status to a remote logic device. Remote Talk and Remote
Mute functions are also provided, and can be activated
using a remote On/Off/Talk/Mute panel.
enables talent and guests to communicate with the board operator. When Talk is remotely
activated on a channel, outputs to program buses for that
channel are muted and the source audio is fed to the
Talkback bus. While this is active, the Preview key will
be lit and the Status Symbol will display the word TALK.
When the user stops talking, the channel immediately
returns to its previous state, and its Preview key flashRemote Talk
es for three seconds, alerting the board operator to the
guest who spoke to him, and enabling him to reply using
the Talk to Previewed Source key.
When the Remote Mute function is activated, the
Status Symbol will display the word MUTE, and will
mute all the channel outputs until the command is released, at which time the channel is again active.
The Studio Monitor speakers will mute when a Studio Guest Microphone channel is turned on, or if it is
assigned to either the Record or Phone bus.
The Studio Guest Microphone channel can be associated with an individual Headphone feed. All Studio
Guest Microphone-associated feeds will monitor the
audio selected on the Studio Monitor selector, but the
board op can communicate with individuals privately
using the Talk To Previewed Source function.

Line Channel Operation
Line-level devices like CD players, delivery system
outputs, tape players, etc., use the Line Channel profile.
The Line Channel is stereo, but the user can change the
input mode to mono, left-only or right-only by using the
Mode function in the Channel Options menu.
Phone Channel Operation
The Phone Channel profile is used for telephone hybrid audio sources. Each Phone Channel has its own discrete Feed-to-Source mix-minus output.
SmartSurface can accommodate up to 16 callers at
a time, and unique mix-minus feeds to callers are generated automatically. If Feed-to-Source is set to Auto
mode the caller hears the output of the PGM-1 bus, minus himself, when a Phone Channel is On. When the
caller’s channel is Off, he will hear anything assigned to
the Phone bus, minus himself. This auto-mode switching can be disabled in the Channel Options menu (see
Page 9). The Phone bus is fed by all channels before the
fader, independent of on/off status.
Line channels have a variety of remote logic functions available at the GPIO interface. On and Off keys
can be remotely controlled, as well as the Preview key.
Each function has a corresponding lamp driver.
A Reset function is provided to remotely turn the
channel Off while suppressing the Stop command, useful for allowing certain types of tape machines to re-cue.
You’ll also find a Ready command which will remotely
illuminate the Off lamp on the SmartSurface channel
and activate the GPIO Off lamp driver, allowing source
equipment to signal the operator with either a steadystate Off button (indicating source ready) or a flashing
Off button (indicating source next). Refer to the GPIO
Node User’s Manual for information on interfacing to
the GPIO’s inputs and outputs.
When a Phone Channel has been assigned to a
SmartSurface fader, the Status Symbol display located
above the channel name will display an arrow and an
icon to show the board operator what is being fed to the
caller.
In Auto mode, the feed-to-source output will normally toggle between PGM-1 and Phone, but it can also
be locked on PGM-1, PGM-2 or Phone, using the options provided when constructing the Source Profile for

Codec Channel Operation
The Codec Channel is used for codec sources. Like
the Phone Channel, each codec source is brought up on
its own channel, and an individual Feed-to-Source (mix
minus) output is provided for each codec source.
Codec Channels can be turned on and off remotely
and will provide on/off status to a remote logic device.
Remote Talk and Remote Mute are also provided, allowing remote talent to take control using their own On/
Off/Mute/Talk panels.

board op using the Talkback bus. When Talk is activated, all outputs for that channel are muted and the source
audio is fed to the Talkback bus. While Talk is active,
the channel’s Preview key lights, and its Status Symbol
will display the word TALK. When the user stops talking, the channel returns to normal, and its Preview key
flashes for three seconds, alerting the board operator to
the source who spoke to him, and enabling him to reply
using the Talk to Previewed Source key.
Talk
EQ
When the remote mute function is activated, the Status Symbol displays MUTE, and all the channel outputs
are muted until the command is released.
The mix-minus output normally feeds PGM-1 audio
to the remote, but can be switched to PGM-2 or Phone.
The Feed-to-Source output on a Codec Channel is a
dual mono output, occupying both sides of the stereo
pair. The Left output is normally used for remote talent’s headphone feed, and is interrupted by Talk To Previewed Source audio when the board op talks to the
remote. The Right output sends uninterrupted program
audio for use as a PA feed.
Feed-to-Source may also be set to Auto mode, which
operates indentically to the Phone channel function described on Page 38.
Status Symbol displays for Codec Channels are the
same as for Phone Channels. The block diagram for this

display screen will show a list of available monitor sources, such as PGM-1, PGM-2, Record, External (generally fed by a tuner or studio processing chain), etc.. Users can also monitor any source
present on the Livewire network. The user rotates
the knob to select the desired source and pushes it
again to “take” that source. If the user enters selection mode but doesn’t make any changes within four
seconds, selection mode exits.
To help protect the user from setting the monitor volume too loudly when the Control Room Monitor is
dimmed (for example, when the Talk To... feature
is in use) and subsequently being blasted when the
dim ends, SmartSurface remembers the previously
set Monitor volume, and restores it as soon as the
dim ends.
The Control Room Monitor Volume knob’s alpha

One of SmartSurface’s most
powerful features is the ability to
instantly reconfigure the entire
surface for different show types.
Join us in Chapter Five to learn
how to set up and use Show Profiles. 
Show Profiles
If you’ve already read Chapter Two, “Configuring
Inputs,” you already have a good understanding of how
Source Profiles are essential to SmartSurface operation.
In the same way that Source Profiles allow you to
pre-determine how an individual channel is configured
when a source is loaded, Show Profiles let you build
configuration files that can be loaded to determine how
the entire SmartSurface behaves, and which sources are
loaded, and on which channels they appear.
By assembling sets of Show Profiles, each user can
have the board set up his or her favorite way — sources
placed where they’re most useful, monitors set to the appropriate feed, headphones conforming to personal preference. Or, you can use Show Profiles to define different
types of broadcasts – one for the morning show, one for
talk segments, one for musical guest interviews, one for
unattended operation – that need only to be loaded to
instantly reconfigure the board for use with a different
situation.
Best of all, since SmartSurface operates in a networked environment, these Show Profiles can be loaded
in any studio in your facility, making studios truly interchangeable at last.
Creating A Show Profile
The first step in building a Show Profile is to set up
SmartSurface using the Channel Options, Monitor Options and Control Options menus described in Chapter
Four, “SmartSurface Operations.” Get started by assigning a source to each SmartSurface channel using the Options keys at the top of each channel.
Reminder: You can speed the setup process
by “Channel Jumping” while using the Options
menus.
For example, to quickly assign sources, select
the Options key on Channel 1 and choose
Source from the Channel Options menu. Use
the Soft Keys or Studio Monitor Volume knob
(flashing SOURCE_1) to select a source from
the list; “take” the source and then press the
Options key on Channel 2. You’ll see the Studio Monitor Volume knob alpha change to read
SOURCE_2 to confirm that you’re now programming Channel 2.
Repeat the procedure until you’ve programmed
all your channels. You can now choose other
Channel Options to configure using the same
method.
After you’ve assigned a source for each channel, you
can configure the rest of the Channel Options::
• Pan and Balance,
• Equalization,
• Feed to Source,
• Aux Sends, and
• Fader Mode.
Build A Show
SmartSurface’s Web interface, which you’ve used
to construct Source Profiles, is also used to build Show
Profiles.
When you first plug in your SmartSurface, it is
equipped with a default Show Profile. This loads the
first time you turn on your SmartSurface; it provides
©2005 Axia Audio — Rev 1.07
Figure 5-1: Channel Options screen.
5: Show Profiles • 51
Chapter Five:
the “blank slate” you’ll use to construct custom Show
Profiles. You might want to load the Default Show Profile from the Control Options menu located beneath
SmartSurface’s Soft Keys to make sure you’re in “ready
mode.”
When you’ve configured all Channel Options, use
the Monitor Options menu to set Control Room monitor
and headphone preferences, the Studio Options menu for
Studio monitor settings, and finally the Control Options
menu if you need to adjust Aux Send / Aux Return settings.
When you’ve got the board configured to your satisfaction, proceed to the next section.
Suggestion: As part of SmartSurface training,
show your talent how to use the Channel Options
and Monitor Options menus (discussed in Chapter
Four) to assign sources and set monitor options.
Capture It!
Let them set up the board exactly the way they
want it. You can then use the Capture command to
save their work. This way, talent gets the satisfaction of personalizing their own SmartSurface configuration — and saves you the work!
It’s now time to save your SmartSurface configuration.
(Sneaky, aren’t we?)
Enter SmartSurface’s IP address in your Web browser
and, if you set a password during initial setup, enter it.
When the Main Menu appears, choose “Show Profiles.” This is where you’ll come whenever you need to
capture, construct or administer a Show Profile.
5: Show Profiles • 52
However, there may be a few more options you’d like
to tweak — options not accessible from SmartSurface
itself. Let’s go a little deeper into Show Profiles to find
out exactly what’s available to you.
In the Show Profiles screen, you’ll find four options:
» Default Show Profile. This is the “starter” profile that comes with SmartSurface. If you wish,
you can overwrite this with your preferred default options; otherwise, consider it as “return to
zero” configuration option, for use in returning
SmartSurface to a “blank slate” condition.
» New Show Profile. Choose this option when you
want to construct an entire Show Profile completely from scratch.
» Capture Show Profile. Takes a “snapshot” of the
current board state and saves it for recall. This is
the option we’ll use in just a moment.
» Sort by Time. Sorts saved Show Profiles in order
of creation date / time.
Since you’ve already set up your SmartSurface, all
that’s left is to capture your settings for further use.
Choose Capture Show Profile from the menu, and
you’ll see a new Show Profile appear in the list next to
the Default profile. Voila! You’ve just created and saved
a Show Profile, which can now be recalled for use whenever you wish.
Note: Talent cannot save changes to shows
themselves. This means that unless the Engineer deliberately “captures” changes, they will
be discarded when loading any profile.
Show Profile Options
Although the ability to create Show Profiles using
SmartSurface’s
“capture”
function is powerful, there are
more options available exclusively via the SmartSurface
Web interface.
In the last section, we
showed you how to capture
the current configuration
of your SmartSurface, easily creating a Show Profile,
which was immediately added to the Show Profiles list.
Figure 5-2: Show Profile
Settings Menu
Now, click on that newly
created profile. It’s probably
named something like “Capture 2004-2-12 0:800” — the
date and time the capture
was made.
You’ll see the menu shown in Figure 5-2. You can

Note that there is currently no option to allow
presetting the fader gain. When you load a Show
Profile which specifies a Locked fader, the gain
value is locked to the position of the fader at the
moment the Show Profile is loaded.
In the same way that the Show Profile Channel Description screens mirror SmartSurface’s Channel Options menus, the Auxiliary Send Description Screen
captures the global Aux Send settings found in SmartSurface’s Control Options menus.
Note: Instead of the Retain Source Settings
option found in the Channel Descriptions pages,
the Auxiliary Send Descriptions Screen features
a new option: Retain Existing Settings. Using this option with any of the Aux Send/Return
settings allows the Show Profile to be loaded

Retain Existing Settings, re-loading that profile will not overwrite the board’s current settings! This means that if a board op gets themselves intro trouble, loading a profile may not
clear the problem!
Because of this, it’s safest to specify values for
every function when constructing a Show Profile – even though it means a little extra work in
setup – unless you have a known need for the
Retain... setting.

SmartSurface’s Preview key acts like a latching switch,
Momentarily pressing any channel’s Preview key
assigns that channel to the Preview bus; pressing it
again removes the channel from Preview. To enable
an operator to quickly listen to various sources, the
Preview function is interlocked: pressing Preview on
any channel will remove any other channel from Preview mode. Operators can momentarily disable this
interlock to add more than one source to the Preview
mix (see the discription of the Channel Preview Key
in Chapter 4, “SmartSurface Operations”, for details).
Preview Interlock Mode: By default,
However, you may wish to disables the Preview Interlock on a global basis. Choosing Enabled for this
setting retains the default operating style; choosing
Disabled shuts off the interlock, so that multiple
sources may be added or removed from the Preview
mix without additional button presses.

FAQ / Diagnostics / Maintenance
This appendix contains answers to some frequentlyasked SmartSurface setup questions, and some troubleshooting procedures intended to determine if factory
service is needed. These procedures are not intended
to take the place of a conversation with Axia support
personnel; should you need to contact us for support,
please use the contact information listed on Page iii of
this manual.
Q: How do I set the IP address of SmartSurface?
Press and hold the Control Options key found in
the center section of SmartSurface just below the
Soft Keys, then press and hold the three Talk To...
keys just below the meters. Hold these keys for 5 seconds; the right display screen will change to the IP
Setup screen.
Q: The SmartSurface web interface asks me for a
password, but I haven’t set one.
SmartSurface is password protected by default to
discourage tampering. We recommend setting your
own password (using the IP Setup screen described
in Chapter One), but until you do, the default password is “user” (without quotes, of course).
Q: I get a “Page Not Found” error when I try to
connect to SmartSurface using my Web browser.
What’s wrong?
It’s possible that your computer’s network configuration needs adjustment. Livewire networks do not assign IP addresses dynamically (DHCP), so double-check
to see if your computer is actually a
part of the network — that the network adapter has a valid IP address
and the proper subnet mask value
assigned. Assuming your computer
is running Windows, you can view
these settings using a utility called
IPCONFIG.EXE. Here’s what to do:
1. Double-check SmartSurface’s IP address
— press and hold the Control Options key and all
three Talk To... keys for 5 seconds, until the IP Setup screen appears on the right display screen. The IP
address and subnet mask values are displayed on the
first two lines. Write this down for reference.
Figure C-1: starting a command box
2. On your Windows computer, click on the Start

four different address formats or classes you can use to construct them. We
recommend that Livewire networks be

Q: How do I set the time on the SmartSurface?
Press and hold the Timer Options key near the
Scrub Wheel. Don’t let go. The right-hand display
screen will change when it enters settings mode.
Look at right display and soft keys for the various
choices; keep the Timer Options key depressed
while you make changes.
Q: How do I make my On-Air lamp illuminate when the Operator’s mic is turned on?
You will use one of your GPIO Node Ports to activate
the relay for your “on-air” lamp. Here’s how:
1. Find the Channel Number previously assigned
to your StudioEngine’s CR Monitor output. If
you did not use a Channel Worksheet to keep
track of assigned channel numbers, you can find
this number in your StudioEngine configuration
web page. Use a Web browser on a computer
connected to your Axia network, enter the IP address of your StudioEngine in the browser’s address bar, and navigate to the “Program & Monitor Outputs” page. You’ll find the CR Monitor
entry about halfway down the page.
2. Enter the IP Address of your GPIO Node in
your Web browser. Navigate to the “Configuration” page and choose the GPIO port you’ll use
to activate your on-air lamp relay. Enter the CR
Monitor Channel Number in the field adjacent
to that port’s name.
3. Enter the IP Address of your SmartSurface in
your Web browser and navigate to the “Show
Profiles” page. Click on the name of any Show
Profile and then choose “Monitor Data Section.”
When the Monitor Data page loads, find the section of the page titled “CR Monitor”, enter the
CR Monitor channel number in the field labeled
CR GPIO.
4.
Repeat Step 3 for each Show Profile to ensure
“on-air” lamp operation no matter which Show
Profile is loaded.
Refer to the GPIO pinout diagrams in Chapter 3,
“Configuring GPIO”, to determine which pins on your
GPIO port to connect to your lamp relay.
Lamp & Display Diagnostics
This section provides instructions for testing
SmartSurface lamps and screens. Follow these instructions:
1. Enter SmartSurface’s IP Setup menu. Press and
hold the Control Options key, then press and hold
the three Talk To... keys just below the meters. Hold
these keys for 5 seconds; the right display screen will
change to the IP Setup screen.
2. Notice that the upper left Soft Key display reads
TEST. Press this to enter Test Mode.
Note: Test Mode has six cycles, which you advance by using the Soft Key labeled NEXT. Note
that you can exit Test Mode at any time by pressing the upper right Soft Key, labelled EXIT.
3. When TEST is depressed, all lamps on
SmartSurface are turned on to verify working status.
These include all fader On and Off keys and all program bus assignment keys and Options keys. The
alpha-numeric displays adjacent to the Soft Keys
also flash.
4. In between flashes, you’ll see that the upper left Soft Key is now labelled NEXT. Depress this key to move to the next test cycle.
The cycles are:
» Lamp Test - all bus assignment keys, Options keys and fader channel On and Off
keys illuminate.
» Status Symbols display test - all Status Symbol display segments flash on and off to verify

Fader Disassembly and Cleaning
1. With SmartSurface closed, identify the fader you
wish to service and open SmartSurface by applying gentle upward pressure on each front corner.
If the surface is locked closed, insert a #00 Philips-head screwdriver in the lock holes located in
the front corners of SmartSurface’s bumper and
rotate counter-clockwise to unlock. After a small
amount of travel, the internal lifting mechanism
will assist you in opening SmartSurface and will
keep it open while you work.
This is the last test cycle, You may repeat the cycles
by using the NEXT key if you wish, or return to normal operating mode using the EXIT key.
Fader Cleaning Procedures
FAQ / Diagnostics / Maintenance • 74
SmartSurface’s single-element, conductive-plastic
faders were chosen for their long life and reliable operation, but jocks will be jocks: it’s inevitable that sooner or
later you’ll need to pull a fader for cleaning.
There are no replaceable parts in the faders used in
SmartSurface. If fader movement has become rough, either the lubricant on the glide rails has evaporated or
foreign material has gotten into the fader. Dow Corning
510 is the preferred glide rail lubricant as it will not migrate to the contact fingers like other lubricating oils.
Figure C-5: Locating fader connections
2. Locate the three-wire cable soldered to the terminals of the fader you’re going to service, and
trace it to its connection point on the surrounding
circuit board (Figure C-5).
Using gentle pressure, pull the red cable connector from the circuit board pins. Lift the white retaining tab slightly to “unlock” it.
SmartSurface faders can be serviced “hot.” If you
disconnect a fader, the StudioEngine will retain the
fader’s most recent settings until the hardware is reconnected.
Tools and supplies you will need to remove and service a fader:
» A 1/16” hex wrench
» A jeweler’s screwdriver (5/ 64” or smaller)
» Cotton swabs
» Dow Corning 510 lubricating oil
Figure C-6: Unplugging the fader connecting cable
3. Now that the fader is disconnected, close the surface and locate the two 1/16” hex screws at the top
and bottom of the fader slot. Use a hex wrench to
loosen these screws, taking care that they do not
©2005 Axia Audio — Rev. 1.07
drop into the fader slot.
4. Raise the surface partway. Hold the fader body
from below while gently pulling up on the black
fader knob. When the fader knob detaches, the
fader assembly will drop out into your hand from
below.
Always use a clean dry swab to dry off the conductive plastic tracks after cleaning. If the fader
rails are noticeably dirty, wipe them off using a
dry cotton swab before lightly lubricating the top
rail with Dow Corning 510.
If coffee, a soft drink or other sugared liquid has
been spilled into the fader, remove it from the
module as soon as possible and remove the top
cover of the fader. Hold the fader under hot running water while moving the fader slider back and
forth to dissolve the sugars and other chemicals.
Thoroughly dry the rails and conductive plastic
using dry cotton swabs and then lubricate the top
fader rail with Dow Corning 510.
Figure C-7: Loosening hex screws
5. Lay the fader assembly on your work surface, label-side up. Remove the snap-on fader assembly
cover; it’s held in place by round stamped bosses
at each end. With the fader sitting label up and
the connector pins to the front, you’ll see a prypoint on the right end of the fader cover (Figure
C-8). Use a jeweler’s screwdriver to gently pry
off the cover.
Figure C-9: Cleaning the fader glide rails
Move the fader slider to the middle of its travel and
place one drop of Dow Corning 510 lubricant on the top
rail on either side of the fader slider bushings. Move the
slider through its full travel to distribute the lubricant.
Wipe off any excess lubricant from the rubber stops at
each end of the glide rail. Normally only the top rail (the
one the fader slider bushings glide on) requires lubricant.
Figure C-8: Pry point on fader cover
Reinstalling The Fader
6. Use a dry cotton swab, or a cotton swab wet with
distilled water, to clean the fader parts.
Note: The use of chemical cleaners on the conductive plastic will substantially shorten fader
life. Never touch the fader slider contact fingers
while cleaning the fader parts.
1. Snap the cover onto the fader body.
2. From below, reinsert the fader into position in the
surface, taking care that the end marked ∞ is installed adjacent to the channel’s On / Off keys.
3. Reinstall the hex screws from the top of the surface. Do not overtighten.

4. Press the fader knob firmly onto the stem.
5. Reconnect the fader lead to its mating pins on the
circuit board inside the Surface.
6. Close the SmartSurface by pulling gently downward on the front corners of the surface; take care
that the lifting assist mechanism does not “snap”
the surface shut. If desired, use a #00 Philipshead screwdriver to engage the closure locks located in the forward corners of the SmartSurface
bumper.

Appendix D:
Phone Controller Installation
If your station uses a Telos Talkshow System, you
may have purchased an optional SmartSurface Console
Director for on-the-board control of your studio phone
system. This Appendix will walk you through installation. You don’t need to power off the Surface during
installation.
If you have not opened the shipping box containing your Console Director, please do so now. Inside you
should find:
» (1) Console Director, static-wrapped
» (1) Ethernet connection cable
If any parts are missing or appear damaged, please
contact Telos Systems Support immediately using the
contact information found on Page iii of this manual.
Installation
Figure D-2: Installed
Console Director panel
Gently lower the Director into the empty SmartSurface bay, taking care not
to catch any exposed components on the bay’s metal
edges. Use the 2 mm. hex screws saved from removal
of the blanking panel to fasten the Director panel to the
SmartSurface.
Now open the SmartSurface by applying gentle
upward pressure on each front corner. If the surface is
locked closed, insert a #00 Philips-head screwdriver in
the lock holes located in the front corners of SmartSurface’s bezel and rotate counter-clockwise to unlock.
After a small amount of travel, the internal lifting
mechanism will assist you in opening SmartSurface and
will keep it open while you work.
First, decide whether
you will install your Console Director in the leftor right-hand expansion
bay of your SmartSurface.
(We’ve chosen to use the
right-hand bay.)

The last step in this proceedure is to connect your
SmartSurface to your phone system.
Figure D-4: Console Director RJ-45 port
Figure D-6: “Phone System” pass-through port
Connect one end of the Ethernet cable supplied with
your Console Director to this port, and the other end to
the RJ-45 port on the Director itself (you’ll find this port
on the front edged of the Director, facing you when the
enclosure is in the “open” position - see Figure D-4).
Route an appropriate length of CAT.5 Ethernet
cable from your phone system to your SmartSurface.
Connect it to the port marked “Phone System” on the
SmartSurface connection panel, as shown in Figure D-6.
Connect the other end to the appropriate port on your
phone system (see the User’s Manual specific to your
Telos phone system for details).

Once the cable is connected to both RJ ports, position it next to the other cable bundles adjacent to SmartSurface’s fader assemblies, and use small tie-strips to
attach it to one of these bundles. Do not leave the cable
loose inside the enclosure, as it may interfere or become
entangled in the moving parts within. A small loop next
to the Master Control module is acceptable if there is
excess cable length.

Appendix F:
Channel / IP Worksheets
The scalable nature of Axia Livewire audio networks makes it possible to construct systems of any size - from a
single room to an entire multi-studio facility.
Since Livewire components – Audio Nodes, SmartSurfaces, StudioEngines, etc. – are connected with Ethernet,
each one requires a unique IP (Internet Protocol) address. IP addresses are four bytes long and are written in “dotted decimal” form, with each byte represented decimally and separated by a period. For example, in the IP address
193.32.216.9, the 193 is the value for the first byte, 32 for the second, etc. Since a byte can hold values from 0 to 255,
this is the range for each decimal value. If you run a public network, Host IP addresses are assigned to your organization by your internet service provider and parceled out to individual host computers by your network administrator.
He may give you this number to be entered manually, or could opt for DHCP (Dynamic Host Configuration Protocol)
to let your computer get the address automatically from a pool. Because Livewire devices are permanently attached
and because it is more desirable to know the IP address attached to a particular node (and perhaps assign them in
some kind of logical pattern), we do not support DHCP for our hardware nodes. Therefore, you will need to enter an
IP address into each node.
Using the audio nodes, Livewire systems can support 32,766 channels of audio; this necessitates giving each audio
source or destination its own unique identifier, called Channel ID numbers.
As you can imagine, keeping track of so many unique IP addresses and Channel ID numbers can be a big job.
Therefore, on the next few pages, we’ve provided you with worksheets that you can use to keep track of the numbers
you’ve assigned.
Worksheets • 83
For a more detailed explanation of IP addresses, subnet masks and related issues, we highly suggest that you refer
to “Network Engineering For Audio Engineers”, Chapter 8 of our Introduction to Livewire: System Design Reference
and Primer.
