some of the primary parts even when the fuse has
blown. If fuse replacement is required, replace fuse
only with same type and value for continued protection against fire.
This product’s power cord is the primary disconnect
device. To prevent risk of electric shock, disconnect
power cord before servicing. The outlet to which this
equipment is connected must be installed near the
equipment, and must always be readily accessible.
The unit should not be positioned such that access to
the power cord is impaired. If the unit is incorporated into a rack, an easily accessible safety disconnect
device should be included in the rack design.
This equipment has an autoranging line voltage
input. Ensure that the supply voltage is within the
specified range.
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.
MOISTURE WARNING:
This equipment is intended for INDOOR USE
ONLY and can be hazardous if immersed in water.
To reduce the risk of electrical shock, do not expose
this product to rain or moisture. Keep moisture away

A Note From The Vice President of Axia
In retrospect, it’s hard to believe it’s been 10 years
since a start-up division of Telos grabbed everyone’s
attention with a radical idea about building radio studios using Ethernet. At a time when “state of the art”
meant discrete digital audio, and a routing switcher
was something only the richest stations could afford, Axia shocked everyone with the idea that studio
peripherals from the console to the audio processor
could be networked, and that everyone could have the
benefits of a routing switcher — for about a third of
the cost of traditional technology.
When we launched Axia, Telos founder Steve
Church made a prediction. “Three things will happen,” Steve told us. “First, people will say that ‘it will
never work.’ When they’re proven wrong, they’ll say
‘It works, but you don’t need that.’ And finally, as they
see Axia becoming successful, they’ll say ‘IP-Audio?
We do that too!’”
Steve, as always, was right on the money. In 10
years, Axia Livewire has become the world’s most
popular IP-Audio networking technology, and our
mixing consoles are the world’s best-selling — they’re
on-air in over 4,000 studios, and counting. You’ll find
Axia equipment everywhere: at privately-owned stations, and large clusters run by big conglomerates. At
established public broadcasters, and at newly-licensed
International stations. At government broadcast facilities, and podcast studios. Needless to say, we’re humbled by the trust broadcasters place in us — and by
your enthusiasm!
Being first with new technology is nice, but we’ve
never been content to rest on our laurels. So the Telos
R&D team continues to innovate and expand the scope
of IP-Audio. Axia consoles are the first and only IPAudio consoles with a pre-configured network switch
built in, to save broadcasters the effort and expense
of procuring and programming third-party switches.
Our compact xNode AoIP interfaces feature one-button setup, and can run on mains power or Power over
Ethernet (PoE) for flexibility and redundancy. We’ve
even developed our own zero-configuration Ethernet
switch for Livewire – xSwitch – to make deploying
IP-Audio easier than ever.
More than 45 Livewire partners believe in the vision of the Connected Studio too. Collectively, they
make dozens of hardware and software products
(ranging from telephone systems to audio processors
to program automation) that interoperate directly with
Axia networks via Ethernet – making the connections “smart”, and eliminating the need to purchase
audio conversion devices. We’ve also partnered with
the high-performance audio standard RAVENNA to
expand broadcasters’ networking options even further.
And there are a lot more great new ideas in the cooker
— so watch this space!
In the final analysis, Axia’s success isn’t due to
our efforts. It’s you, the broadcast professional, who
has embraced our vision, used our technology in ways
we never dreamed of, and raved about Axia products
to everyone who’d listen. We owe you a huge debt of
thanks. And we promise to never stop trying to amaze
and delight you.
So here’s to the next 10 years.
Onward and upward!
Marty Sacks
Vice President, Axia Audio

The following chapters of this manual will give
you an in-depth understanding of the capabilities of
your new RAQ or DESQ surfaces, from installation to
advanced functions. This section will help you get everything connected quickly, and point you to the parts
of the manual you’ll need to get up and running with a
minimum of fuss.
RAQ consists of these components:
• RAQ mixing surface: 6-fader rackmounted
frame with master controls and meters.
• QOR.16 or QOR.32: Rack-mounted CPU chassis with audio I/O and GPIO connectors.
DESQ consists of these components:
• DESQ mixing surface: 6-fader frame with
master controls and meters.
• QOR.16 or QOR.32: Rack-mounted CPU chassis with audio I/O and GPIO connectors.
Making Connections
You’ve probably unpacked your boxes and are sitting
next to a pile of Axia gear, wondering what to do first.
Here’s what you need to know in order to get started:
1. Packed with your RAQ/DESQ is a cable with
6-pin MolexTM connectors on each end. This is the
power/communications cable. Connect the end of
the cable without the strain relief to the port on the
underside of your RAQ or DESQ control surface.
Connect the other end of the cable to the connector
labeled CONSOLE on the back of your QOR unit.
2. Connect audio sources (microphones, CD players, etc) to inputs of your QOR.
3. Connect monitor amplifiers, headphone amplifiers, etc to outputs of your QOR. Be sure to set all
amplifiers to their minimum volume setting.
4. Follow the instructions found in Chapter 1 to
configure IP address settings for your RAQ/DESQ.
5. Refer to the User’s Manuals packed with any
other Axia Audio nodes for information on how to
configure IP addresses for these units.
When you’ve completed physically connecting your
Axia hardware, jump to Chapter 2 for a quick tutorial
on configuring audio sources. With that done, you’ll be
a hop, skip, jump away from being on-air! After that,
you’ll likely want to do some in-depth reading about all
that your new console can do. Here’s a brief description
of the contents of the following chapters:
• Chapter 1: Setup and Connections explains connections and basic setup.
• Chapter 2: Inputs and Outputs explains how to
generate Source Profiles and construct backfeeds
for selected sources.
• Chapter 3: Surface Operations takes you behind
the scenes to explore operator controls and options.
• Chapter 4:Show Profiles illustrates how to set and
save unique “snapshots” tailored for specific shows.
These Show Profiles can be instantly recalled whenever needed.
• Chapter 5: GPIO tells how to associate routable
logic commands with any audio source.
• Chapter 6: Advanced Controls discusses advanced
features that are configured in configuration web pages.
• Chapter 7: Livewire Networking and QOR will tell
you how to connect your console to a network and
reap the benefits of networked studio systems.
• Appendices provide additional technical specifications and a complete set of block diagrams for your
reference.

Setup and Connections
Introduction
If you are reading this manual, you are probably the
proud owner of a new RAQ or DESQ console. Thank you!
The Basics
This chapter covers connecting the QOR to your
other studio gear, such as microphones, CD players and
other audio playback devices. The audio outputs of the
QOR connect to control room monitors, preview (cue)
speaker, headphones amplifiers and audio recording devices. These external audio devices may be analog or
AES devices.
The GPIO (General Purpose Input Output) ports provide logic control interfaces to devices such as air lights,
recorders and CD players.
The 100 Mbps Ethernet ports may be used to connect PCs running Axia’s IP-Audio driver, to expand your
system by adding other Livewire devices such as Axia
Audio Nodes, or equipment from Axia Partners (see
­AxiaAudio.com/partners/ for the latest list of companies
whose equipment connects directly to Axia networks).
1000 Mbps (Gigabit) Ethernet ports are used to connect to other QOR units or an Ethernet core switch - another topic covered in Chapter 7.
A 6-pin Molex connector is used to connect your
RAQ or DESQ surface with the QOR mixing engine.
Assigning an IP Address
Before you can configure your hardware, you’ll need
to assign it an IP address. Press-and-hold the Meter Options key for five seconds. The meter display now shows
the options and the Preview control is used to navigate,
select IP Address options and change parameter values.
Each QOR requires a single, fixed IP address. The
RAQ or DESQ control surfaces are controllers for the
QOR, so they share the same IP addresses. See Chapter
7 for more details when multiple QORs are used or when
a QOR is a part of a larger network.
Notes on Physical Installation
The QOR is fan-free, so it can be located in any studio without fear of unwanted noise. Those vents and heat
sinks serve a very important purpose! Be sure to mount
the QOR in an equipment rack with free air flow. We
recommend using a ventilated 1RU rack spacer above
and below the QOR to ensure adequate ventilation.
To install the DESQ surface in your studio, all you
need is a desk – no cutout required. To install the RAQ
surface, all you need is 4 RU in a standard 19 inch rack.
QOR: Front Panel
The indicator panel of the QOR, shown on the following page, is very simple. There are no controls for you to
push or turn. Configuration and setup is performed from
the console itself or through the web browser interface.
Front Panel Indicators
Even though there are no knobs or dials, the front
panel has some very useful indicators that tell you about
the health and status of your QOR. In all cases, solid
GREEN indicates normal operating conditions.
CHECK
This is a general health indicator for the QOR. If this
indicator is RED, immediately check the web pages for
abnormal operating conditions such as excessive CPU
temperature. Do not ignore this indicator. Note that it is
normal for this indicator to flash during boot-up.
LIVEWIRE
When lit, indicates that Livewire channels are being
taken from the network. If no network sources are being
received, this indicator is not illuminated.

Chapter One:
Consult your network administrator if you are unsure
about what address to use.
Figure 1-1: QOR - Front Panel
SYNC
If the QOR is part of a larger network, a solid
GREEN indicates the QOR is synchronized as a slave
to the Livewire network and that its internal clock is
locked. Flashing GREEN indicates that sync packets are
being received, but that QOR is not yet locked. It is normal for the SYNC indicator to flash for several seconds
at startup. If it does not “lock” with a solid, non-flashing
LED, this may indicate an incorrectly configured network switch. Check your Ethernet switch configuration
or call Axia 24/7 Support for assistance.
MASTER
Solid GREEN indicates the QOR is synchronized as
a Master clock to the Livewire network. This indicator
will always be green for a standalone console. If you
have any other Livewire devices, they should be reporting Sync or Slave. There should be only one Master
clock device in a Livewire network at any given time.
1: Setup and Connections • 6
Note: The MASTER and SYNC indicators are not
normally ON at the same time since the QOR will
be either a Master or Slave. This principle applies to all Axia Livewire devices. Any Livewire
network will have only a single Master.
NET 1 and NET 2
When the Gig1 or Gig2 ports have active connections, the NET1 or NET2 lamps (respectively) will illuminate. If a network cable is connected to a Gig port and
the corresponding NET lamp is unlit, a problem with the
network connection is indicated.
When a disconnected Ethernet link has been re-established, the NET LED will blink with a 50% duty cycle
for about 5 seconds as the network activity is resumed.
Please consult Axia’s Ethernet switch configuration
guides for details when using Core switches in a larger
network. Ethernet Switch guides may be found on our
web site at AxiaAudio.com/manuals/.
PSU
The PSU indicator provides assurance that the QOR
power supply rails are normal. Solid GREEN indicates
normal power supply status.
IP
This indicator will illuminate upon detection of an
external Ethernet core switch connected to the QOR.
QOR: Rear Panel
Power
• AC Mains: There is one standard IEC receptacle for
your mains power for voltages in the range from 100
to 240 VAC at either 50 or 60 Hz.
Audio Connections
The QOR’s rear panel contains all of the connectors
used for audio I/O, Ethernet, GPIO, power supply and
the connections to your control surfaces. Note that we
use RJ-45 connectors for three purposes:
• Analog audio inputs and outputs
• AES audio inputs and outputs
• Ethernet (some with PoE - Power over Ethernet)
It is important to follow the proper conventions for
wiring these connectors and ensure that the connector
functions are not confused as damage may result if you
plug a network cable into an audio input.
Analog and AES Audio
The connector pin functions shown in Figure 1-3 are
the same for both the AES and Analog inputs and outputs.
©2014 Axia Audio - Rev 1.1.1
Figure 1-2: QOR.16 - Rear Panel Connections
The nominal audio level for analog line inputs and
outputs is +4 dBm. This audio level will provide you
with 20 dB of headroom.
Microphone Inputs
There are XLR-F connectors on the rear panel for
connection of microphone inputs. These connectors use
the standard wiring convention for 3-pin XLR audio
connectors. These connectors may have 48-volt Phantom power enabled via the QOR’s web page configuration. Please take appropriate precautions if you connect
anything other than a microphone to these inputs when
Phantom power is enabled.
Figure 1-3: RJ-45 Audio Connector Pinouts
GPIO Connections
The QOR includes GPIO ports, with pinouts in the
same configuration as the GPIO ports on other Axia
products. Please refer to Chapter 5: Configuring GPIO
for the functions of these ports and wiring diagrams for
their DA-15 connectors.
©2014 Axia Audio - Rev 1.1.1
1: Setup and Connections • 7
Note: The well-labelled RJ-45 connectors on
the QOR rear panel are used for different functions. Be sure to use them only for their intended purpose as described in this section.
RAQ/DESQ CANBus Connections
RAQ/DESQ frames need only a single data / power
connection to operate. The QOR includes the needed
power/CANBus connections for use in conjunction with
your control surfaces. The accessory CANBus port is an
additional port that is available for future use.
Important: Like any electronic device, RAQ/
DESQ can be affected by static electricity. Use
of a personal grounding device is strongly recommended while handling the unit during installation.
Figure 1-4: GPIO Connector Pin-Outs
In most cases, a GPIO port will be associated with
a single source such as a CD player, studio microphone,
profanity delay, et cetera.
Optional PathfinderPC software may also be used to
monitor and control GPIO for advanced applications.
The interconnections to GPIO ports will vary depending on the type external equipment being used and
whether or not voltage is supplied by an external device.
Chapter 5: Configuring GPIO provides these details.
1: Setup and Connections • 8
Ethernet Connections
The QOR has three types of Ethernet connections
and it is important to use them as intended since the internal Ethernet switch is configured in a specific manner.
The types of connectors available are:
• 100 Mbps PoE (Power-over-Ethernet) ports designed
to be used with future Livewire accessories that will
obtain their power directly from their Ethernet connections. These ports may also be safely used with
standard, non-PoE devices.
• 100 Mbps Ethernet standard ports are used to connect PCs or other Livewire devices to your Livewire
network. These devices might include additional
Livewire nodes or PCs running the Axia IP-Audio
driver.
• Two 1000 Mbps (Gigabit) ports are used for connections to other QOR units, or, in larger networks, for
connections to an Ethernet Core switch. Note that
these two ports are used as trunks and are not intended for connection to Livewire source devices such as
Audio Nodes.
Your RAQ/DESQ surfaces must be connected to a
grounded metal permanent wiring system or other equipment grounding conductor using the grounding lug located on the console chassis. For ground sources, we
recommend, in order of preference:
• “Station Ground,” the heavy copper strap found in 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 the mixer.
Important: 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 above, use the specific “Safety Ground”
your local regulations mandate.
Console
There is one 6-pin Molex connector that is used to
provide DC power (48 vdc) plus CANBus data to your
control surfaces.
The RAQ and DESQ surfaces must be connected to a
CanBus port on the QOR using only the supplied 6-conductor cables. One end of the CANBus cable is fitted
with a strain relief. Connect this end to the Molex connector on the back of the QOR. Connect the other, smaller connector to the Molex socket on the control surface.
©2014 Axia Audio - Rev 1.1.1
Note: After making changes to any QOR IP
address settings, you must reboot the unit for
these changes to take effect.
Figure 1-5: Detail of data/communication cable ends.
Since the CANBus connection cables include power
as well as data, there is a length restriction of approximately 50 feet. If you require longer cables than those
supplied with your QOR, please contact your Axia representative.
IP Address Configuration
To access System Settings from a RAQ or DESQ
surface, press-and-hold the Meter Options key for five
seconds. The Meter display now shows the options and
the Preview control is used to navigate, select options
and change parameter values. Options available are:
•
•
•
•
IP Address
Subnet Mask
Gateway
Save and Reboot
“Gateway” settings on an QOR are not usually required; however, a valid gateway enables access to the
QOR configuration remotely, from outside your network. A gateway also facilitates the use of an external
NTP server. Enter the IP address of your master router
(the one with external network connections) whenever
you’re given the option to enter a gateway address.
Note: If your system employs an Ethernet core
switch, the Ethernet core switch must have an
IP address that is lower than any of your QOR
units or Ethernet edge switches. This function
of the IGMP standard ensures that the multicast
querier is handled by the core switch if one exists. The querier will be passed off transparently
to another switch should the core switch fail or
be disconnected.
What’s Next?
Take a break! You’re done with initial set-up. When
you’re ready, continue to Chapter 2: QOR Inputs and
Outputs to walk through the software configuration of
the Inputs and Outputs on your QOR.

that accommodate microphones, analog stereo line and
AES inputs. Chapter 1 discussed the details of these
physical connectors. Now, let’s look at the software configuration of these inputs.
In this chapter we’ll discuss how to configure the
inputs and outputs for your RAQ and DESQ consoles
by using your computer’s web browser. While browsing
this chapter you may find useful the block diagrams in
Appendix B.
QORs have built-in Ethernet switch and Web serverfor options configuration. To access it, all you need is
a computer connected to its Ethernet switch. Since
Livewire IP addresses are managed without DHCP, you
will need to ensure that your PC has a manually-assigned
IP address in the same subnet as the QOR. Contact your
network administrator if you are not sure how to set up
a fixed IP address for your PC (but if you’re reading this,
we think you’ve probably got it covered yourself).
Note: Axia web interfaces have been tested with
Microsoft(TM) Internet Explorer, version 6 or later, but also work with other browsers.
Once your PC is properly connected to the Axia
Livewire network, direct your web browser to the IP address of your QOR. When you connect to it, you will be
prompted for a user name and password. By default, the
user name is “user” and there is no password.
First, we’ll walk through the Audio IO Manager to
configure your Inputs and Outputs. Then, we will illustrate how Source Profiles and Show Profiles are used
with your QOR system.
Inputs
Figure 2-1 shows the web page configuration for Inputs for your QOR. There are three types of inputs.
Microphone Inputs
XLR-type connectors on the rear panel are intended
to be used for mono microphone signals. Each of those
inputs has the following parameters:
• Phantom Power (48 vdc) is individually enabled
for each of the four microphone inputs by selecting
this check box.
• PreAmp Gain is adjustable to a maximum of 65 dB.
This setting will adjust the microphone level prior to
all other signal processing.
• Input Gain is adjustable from -64 to +24 dB. If you
are conservative with your PreAmp gain, you may
wish to apply a few dB of additional gain at this stage.
Analog Line Inputs
Your QOR has several connectors on the rear panel
The eight inputs in the QOR.16 or 16 inputs of a
QOR.32 are for line-level stereo signals connected to

Figure 2-1: Audio IO Manager - Inputs from QOR.32
the analog line RJ-45 connectors on the rear panel. They
have only one adjustment.
• Input gain allows you to specify a gain from -64 to
+24 dB.
AES/EBU Inputs
AES/EBU digital inputs are on RJ-45 connectors.
The digital input is equipped with a sample rate converter so a specific incoming sample rate or AES clock
is not required.
• Input gain allows you to specify a gain from -127.5
to 0 dB.
Be sure to click Apply after making changes in each
input section.
Now that the inputs have been tweaked for proper
system audio levels, we can manage that audio and automatically associate logic with the different sources you
have connected to your QOR. We use a concept that we
call Profiles to do this.
2: Inputs and Outputs • 12
What’s a Profile?
A Profile is a group of console parameters that are
stored in memory for instant recall. The use of Profiles
makes the operation of your RAQ or DESQ quick and
intuitive. In the RAQ/DESQ console’s design, there
are two types of profiles: Source Profiles and Show
Profiles. Show Profiles (discussed in detail in Chapter
3) contain all of the “snapshot” settings that would be
associated with a scene or preset. This terminology is
commonly used in the sound reinforcement or recording
studio industries.
Show Profiles
Our Show Profiles keep track of monitor bus settings, fader channel assignments, jock preferences, feature lockouts and many other parameters.
You will use your web browser directed at the IP address of the QOR to set up RAQ and DESQ options including both types of profiles.
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 analog line selector modules: you
needed 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 logicfollows-audio often turns out to be not so simple.
Mix-minus and IFB generation has also been a problem in the past. 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 been aired thanks to this error-prone
procedure?
The RAQ/DESQ eliminates these headaches by automatically merging 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 the audio. This association is accomplished through the use of
Source Profiles.
A Source Profile contains all of the parameters that
are unique to a specific audio input (source) as it applies
to a specific RAQ or DESQ console. Source Profiles can
assign modifiers to an audio input. Characteristics like
Pan, Trim and even Mix-Minus source selections can be
set in the Source Profile and automatically loaded whenever that source is assigned to a RAQ or DESQ fader.
The result of all this is that RAQ or DESQ is always
presented with complete, consistent information about
how you want a given audio input (source) to be handled.
Your board operator will never have to worry about MixMinus again!
Source Configuration
The QOR web browser interface is used to configure
Sources. To get started:
• Open the web browser on your computer and point
it to the IP address you previously assigned to your
QOR.
• You’ll be prompted to enter a user name and password.
©2014 Axia Audio - Rev 1.1.1
The default user name is “user”. Leave the password field blank.
• Select Sources to proceed to the source setup page.
Figure 2-2: Source Profiles
You will now see the Sources section as shown in
Figure 2-2. In this example, many of the sources have
already been configured.
Note that there are three different classes of audio
sources. Most originate with the rear panel input connectors and are used locally with a RAQ or DESQ; some
audio sources may be obtained from other devices in
your Livewire network, and some audio sources (PGM1,
PGM2, etc) are generated internally.
trol room. Its associated logic automatically mutes
the CR monitors and Preview when ON.
• External Mic is used for any mic ­located outside of
a CR or studio. It functions like a Guest microphone
but does not include any muting logic.
• Line is used for any line input audio source, analog
or digital. A GPIO logic port can be used to provide
machine start/stop pulses if desired.
• Phone defines this source as a hybrid or broadcast
phone system input. A summed mono mix-minus is
automatically provided.
• Codec marks this source as a codec. A dual mono
mix-minus is provided; one PA feed (right) + one talent feed with talkback (left).
• Computer Player defines this source as originating
from a PC. Associated GPIO logic can be used to
send start/stop signals to a playout system.
• Studio Feed defines a source that receives a backfeed, and generates an IFB backfeed in return. This
is intended for an external studio source which you
wish to generate a talkback channel for.
Once you have selected the source type, click the
Create button to proceed to the Source Profile options.
Creating a New Source
Your first choice defines what type of source you’re
setting up, which is important since GPIO, mix-minus
and other console behaviors are decided based on your
choice. Your choices:
• Operator is the board operator’s mic. It is the source
mic for TALK TO functions. Its logic mutes the CR
monitors and Preview when ON.
• Producer is used for in-studio Producer’s mic positions. It has associated GPIO logic which can operate
TALK TO functions from a remote producer’s panel.
It also mutes CR monitors and Preview when ON.
• CR Guest is used for any other guest mic in the con©2014 Axia Audio - Rev 1.1.1

With that in mind, let’s discuss configuring your local
sources and making them available for fader assignment.
Figure 2-3: Operator Microphone Source
Figure 2-3 shows the setup options screen for a
typical Microphone source. Figure 2-4 shows a Codec
source which has a few different settings, and Figure 2-5
shows a Line source. The following sections describe
these Source configurations in detail.
Source Type
This display-only parameter shows you the source
type as selected in the previous step (Line, Codec, etc).
that it is a network source originating from some other
Livewire device. When you choose Livewire as your
Source Input, you will specify a network source. See
Chapter 7: Livewire Networking for details.
Primary Source
This pop-up window is used to select the network
Livewire source ONLY when Livewire has been selected as your Source Input. See Chapter 7: Livewire
Networking for more on this.
Signal Mode (Non-Microphone Sources)
Determines whether source will be treated as a mono or
stereo source.
• Stereo feeds incoming L/R signal to left and right
channels of assigned bus(es).
• Left feeds incoming left channel to both channels of
assigned bus(es).
• Right feeds incoming right channel to both channels
of assigned bus(es).
• Sum creates L+R mono mix of incoming stereo
source and feeds it to both channels of assigned
bus(es).
Signal Phase (Non-Microphone Sources)
Determines whether source will maintain normal or
inverted phase relation.
Fader Trim Gain
This setting allows you to specify an amount of gain
from -25 to +25 dB. Fader Trim Gain is applied in the
signal path just before the fader.

Figure 2-4: Codec Source
Source Name
Each Source needs a name for display on the console’s OLED channel displays. Names can be up to 10
characters long and may include spaces or underscore
characters.
Source Input
This setting associates the source with an audio input.
It may be a local input in which case you would choose
a local Mic, Analog or AES from the drop-down menu.
This source may also be a Livewire source which means
Panorama Position
Lets you preset pan settings for this input. Pan is
variable in 49 steps, center being 0, far left -24 and far
right +24. This setting can be adjusted on the fly by the
operator if permitted by show profile settings.
Equalizer
If the check box is selected, the EQ function is enabled for this source profile. The EQ function provides
three band EQ with sdjustment of the frequency of each
band and the gain of the band. The QOR has a limit of 8
simultaneous channels with EQ.
©2014 Axia Audio - Rev 1.1.1
Source Availability
These check boxes determine which faders (or other
inputs) 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 left-most 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 faders.
You might wish to prevent some sources – especially
off-air signals – from ever being assigned to a fader, so
you would un-check the boxes for all faders.
Preview Switching
There are two check boxes in this area. None, either
or both may be checked. The options are:
• Channel ON turns Preview OFF
• Preview ON turns Channel OFF
Auto-Start Timer
When this box is checked, the count-up timer will
start when the channel is turned ON (timer function only
supported in DESQ).
The two final check boxes, External and V-Mixer,
determine whether the board-op will be able to assign
the source directly to the CR monitor and headphone
buses, or to the Virtual Mixer.
Fader Mode
Defines fader start actions and start logic:
• Normal conforms to the US method of requiring talent to manually turn the channel on and off.
• Fader Start follows the common European standard of activating the channel and associated machine logic when the fader is raised from - ∞.
• Fader Start with Arm works just like the Normal setting when the fader is not set to minimum
position. When the fader is set to the minimum
position, it can be in an Armed state. This armed
state is entered by pressing the ON Button when
the fader is down. The armed state means that the
channel will go to the ON state when the fader is
moved up. The channel ON lamp will flash in
“wink” mode - a long on-time and short off-time.
Preview Mode
Permits you to choose whether Preview acts in CUE
(pre-fader) or SOLO (post-fader) mode.
Figure 2-5: Line Source
Logic Port
Allows you disable GPIO machine logic to this audio source device or enable it in two modes. Exclusive
mode permits GPIO control associated with only a single fader. Shared mode allows more than one user to
send ON/OFF/START signals to the source via GPIO.
Feed to Source (Codec, Phone, Studio Feed only)
If this source is a Phone or Codec type and there is a

To prevent a source from appearing on these inputs’
selection lists, un-check the relevant box. Generally
speaking, you’d want to restrict sources such as computers and CD players to fader assignments while sources
such as off-air receivers would be marked to appear only
on the External monitor selection list.
backfeed associated with it, this option determines what
audio content is sent back to the source from the console.
• Disabled - No backfeed.
• Auto (Pgm-1/Phone) feeds the Program 1 bus
(minus the source) when this source’s fader is ON,
and feeds the Phone bus (minus the source) when the
fader is OFF. Remember, the Phone bus is actually a
special variant of Program 2. The Phone bus is prefader and pre-on/off to allow speaker-phone style operation thru the Operator’s mic.
• Program 1 always feeds the Program 1 bus, minus
the source, regardless of the on/off state of the channel.
• Program 2 feeds the Program 2 bus, minus the
source.
• Phone feeds the Phone bus, minus the source. Phone
is a pre-fader and pre-on/off variation of Program 4
• Talk Only is a “silent backfeed” that operates when
the Talk To function is engaged, creating an IFB to
the source.
2: Inputs and Outputs • 16
Feed to Source Dim Gain (Codec, Phone, and Studio
Feed only)
Normally, Talkback is sent over dimmed backfeed
audio. If you want a hard interruption (Talkback interrupts Program audio), un-check the Enable check box,
which mutes the audio. But maybe your jocks would like
to have just their program audio dimmed, with Talkback
heard over it so they can still monitor air while they’re
being talked to. In this case, input a value by which the
program audio will be dimmed. Adjustment range is 0dB
to -30dB.
Live Controls
This group of radio buttons configures permits “live”
functions for the Options control on each of the console’s fader strips. Available options will vary depending on the source type. One setting may be defined as
the Primary or “live” control, which means that the
­Options control will vary that setting as soon as you adjust the knob. For example, if PANORAMA has been
defined as the Primary function, simply rotating the Options control will pan the source.
The other functions may be enabled or disabled as
desired. Those that are Enabled may be chosen by the
operator “on-the-fly” by depressing the Options control.
When the control is pressed, the OLED display will list
the options that you’ve checked as Enabled in this section of the configuration. Pressing the Options control
selects the highlighted option and turning the Options
control will adjust the parameter for that option. Depending on the enabled options, the operator will be able
to adjust Source, Gain, Mode, Pan and Backfeed.
Remember to save your work! You may also “Save
as Copy” if you intend to set up another, similar source
— you can save a few clicks this way.
Congratulations — you’ve created a Source Profile
You can now bring up your new source on a fader.
Figure 2-6: Assigning an Output from the list box
QOR Outputs
Now that we have configured sources, let’s look
at the two kinds of outputs of the QOR, Local and
Livewire (network).
• Local Outputs - These outputs correspond to the audio connectors on the rear panel of the QOR. These
are used to connect Control Room monitors, Preview
speakers, headphone amplifiers, record devices and,
of course, your air chain equipment and processing.
• Livewire Outputs - This is a group of specified audio
©2014 Axia Audio - Rev 1.1.1
streams that can be delivered from your QOR
• to other devices in your Livewire network. See
Chapter 7: Livewire Networking for more details
on how this works.
of the network, they can be loaded on any local or networked console fader, or routed to any other network
destination.
Local Outputs
The QOR.16 has four stereo analog line outputs and
one AES output. The QOR.32 has 8 stereo analog line
outputs and two AES outputs. These may be configured
to deliver:
»» Local source (microphone, analog, or AES/EBU
inputs)
»» Backfeeds to any of the above sources that are
configured as Phone or Codec.
»» Any of the Program or Monitor feeds that are
created by the QOR. (CR Monitor, Studio Monitor CR Headphones, VMIX, VMODE, etc)
• Output - Using the drop-down menu, select the desired source that you want to deliver to your local
output.
• Output Gain - The output signal level may be attenuated to provide an optimal level for outboard devices. The gain range is from -127.5 (off) to 0.0 dB
(unity gain).
V-Mixer Controls
CAUTION - Once you have made a selection
and applied it, audio is immediately delivered to
the QOR output. Be sure to turn down all amplifier level controls to avoid damaging your precious equipment — especially your ears.
The V-Mixer works independently of the console.
Static control of V-Mixer is available through the web
pages.
Even though the “V” in V-Mixer stands for “virtual”,
you can in fact perform a certain amount of “hands-on”
mixing. Although you don’t have physical control of the
virtual faders or virtual ON/OFF switches, adjustments
made to the V-Mixer take effect as soon as you apply
them. While you may not want to operate an entire show
this way, it’s valuable to know that V-Mixer changes
made “on the fly” will take effect immediately.
At the top is the V-Mix Master field. This gives the
option to assign a Livewire GPIO channel for control of
the VMixer. This channel number also gets assigned to
a GPIO port, allowing you to have ON/OFF control of
VMix channels through GPIO. The last option applies a
gain stage to the final mix the five inputs. If the Logic
Port is given a value other than 0, the HTML control of
the vmixer will be forfeited.
The V-Mixer is an “auxiliary” mixer that can be used
to mix five stereo sources and from this mix, create another new Livewire source that may be used like any
other audio source.
V-Mode is a signal converter that allows you to manipulate some mono-mode sources. V-Mode has one input and one output, thus creating one additional source.
V-Mixer and V-Mode outputs are assigned in the
QOR Outputs section and delivered to your Livewire
network. Once V-Mixer and V-Mode signals are a part
Figure 2-7: V-Mixer and V-Mode
Controls for the V-mixer’s input channels include:

any source previously defined with a Source Profile.
• On: Simply determines the ON/OFF status of the individual V-Mixer channel.
• Gain: This setting allows you to specify a gain setting for the channel that will control its mix level.
The range is from -80 dB (effectively off) to +10dB.
Note that you may also specify a gain setting for the
V-Mix Master, which is the output of the V-Mixer.
At the bottom of the V-Mix section is an ­Apply button. Any changes you make will be saved when this button is pressed. Be sure to save your changes.
What does V-Mode do?
All of the program busses of the are stereo. Sometimes, though, special circumstances require only one
channel of an audio source, or a mono sum. V-Mode lets
you accomplish this easily.
Since making a mix-minus and mapping contact closures is often done at the same time a new Source Profile
is constructed, let’s briefly recap those procedures.
Let’s say you’ve connected a hybrid to Analog Input
5 of your QOR. You’ve 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, in your hybrid’s Source Profile, the Source Type option is set to “Phone” and
the Feed to Source is set to “Auto (Program 1 /
Phone)”.
2. Use your Web browser to connect to the Outputs screen (Figure 2-6) and set up the mix-minus for
Output #5.

V-Mode Controls
V-Mode allows you to perform special manipulations
on a stream. The controls are as follows:
• Input Selector contains a drop down menu that allows you to select from a range of sources for each
V-Mode input. You may choose from local Core
sources and VMIX.
• Audio Mode is the magic box that transforms your
stereo stream into something else. You may choose
from any of the following options:
»» Pass Stereo: Passes the Left and Right channels as is, without modification.
»» Mono sum to L: Creates mono sum and directs
it to the Left channel only.
»» Mono sum to R: Creates mono sum and directs
it to the Right channel only.
»» Combine from left and right: Creates a dual
mono stream by summing the Left and Right
channels.
The output of V-Mix and V-Mode channels can be
assigned to outputs like any normal audio source.

name
box, you’ll see a drop-down selector. Click on the
drop-down for output #3 and choose to Analog 5 as
shown in Figure 2-6. By simply choosing to Analog 5, QOR knows to deliver a backfeed that is a
mix-minus of Analog Input 5. (The output chosen to
deliver this backfeed is arbitrary - we chose Output 5
just for this example.)
4. Click Apply.
5. Now point your browser to the GPIO Configuration screen (Figure 2-8). You may also use a GPIO
Node in lieu of QOR’ built-in GPIO ports; just point
your browser to that Node’s IP address instead.
6. The GPIO setup screen uses the same method
of assigning devices to ports as other Livewire devices. Pick a port to map your Phone channel’s contact closures to, using the list tool, and click Apply.
Figure 2-8 shows the GPIO section of a QOR (Axia
Element consoles and GPIO nodes are similar, and
also have eight GPIO ports.)
The process is complete: you’ve made a Source Profile for your phone hybrid, created a mix-minus, mapped
it to an audio output, and associated a GPIO port for contact closures associated with the source.

Console Operation
Overview
RAQ and DESQ are designed to perform well in
small studios. The clean interface enhances speed and
accuracy without clutter or confusing controls.
In this chapter we’ll first give you a high-level overview of the capabilities of the surfaces. Then, we’ll give
you detailed explanations of the various controls and
functions.
Displays
RAQ and DESQ have an OLED display for metering.
The meters can be configured to VU or PPM metering
standards.
RAQ/DESQ have a dedicated meter displaying Program 1 and the second meter postion can display other
buses by pressing the meter button.
In addition to the meter displays, the DESQ has a
time of day clock and a count-up timer. RAQ does not
have this additional display.
“Channel” would normally be used when referring to
DESQ’s linear faders or RAQ’s rotary faders and associated controls, OLED displays, bus assignment keys, etc.
Sources are assigned to faders for use on-air or in
production. During initial configuration, the Source
Profiles are programmed by the engineer for appropriate logic and options (as outlined in previous chapters);
afterwards, whenever that source is assigned to a fader,
source logic follows.
Fader settings are instantly reconfigured whenever a
source is selected, to accommodate the unique requirements of the source. For example, a fader controlling a microphone source also controls appropriate monitor mutes.
A fader controlling a line source may send “start” and
“stop” commands when the channel is turned on and off.
Sources such as an off-air feed can also be assigned
directly to the monitors for auditioning without being assigned to a fader.
Mix-Minus
Mix-minus setup, especially for live broadcasts, has
always been one of the most confusing aspects of running a radio console. RAQ/DESQ makes mix-minus
easy by automating it. The operator never has to worry
about sending a source back to itself and getting feedback — it just can’t happen!
Show Profiles
The RAQ or DESQ can be completely re-configured,
instantly, to suit different types of needs. By recalling
any of four previously stored Show Profiles, talent can
change board settings to suit different needs at the touch
of a button.
Show Profiles are easily toggled by pressing the Profile key located at the top of Monitor section. Construction and administration of Show Profiles is covered in
Chapter 4: Show Profiles.
Several fixed and auto-switching mix-minus choices
are possible, and are configured for each source when
Source Profiles are defined by the engineer (see Chapter 2 for details). Once this setup is done, no further
tweaking is needed; the operator simply uses the source.
A fader’s status display tells operators when a particular source has a mix minus output, and even tells them
which audio mix is being backfed.
Sources, Channels and Faders
During the course of this chapter, we’ll refer often to sources and channels. These are not the same!
“Sources” are microphones, CD players, outputs from the
RAQ/DESQ will generate as many mix-minus outputs as there are faders, each with its own automated
mix minus feed. Each of your six faders can produce a
mix-minus!

Chapter Three:
playout system, telephone hybrids, etc.
GPIO
Chapter 2 explained how sources can have associated GPIO (General Purpose Input/Output) control associated with them. External GPIO interfaces are connected to QOR via the Livewire network (more details
in Chapter 7) , 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. For example, studio mics 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 that each studio guest can have
their own On, Off, Talk, and Mute keys.
Line sources can be configured to receive start and
stop commands from the QOR as well. Start/stop messages can also be passed, via Ethernet, to a computerbased playout system.
3: Console Operation • 22
Software
The QOR operating system uses a high-performance
embedded Linux kernel to help ensure bulletproof, 24/7
operation. Software updates can be obtained from Axia
via the Internet and applied by the station engineer. Axia
Support recommends performing backups or making
printouts of Show Profiles and other configuration data
before applying new software updates.
Callouts and Operation
This section provides a “bird’s-eye view” of the RAQ
and the DESQ, with full descriptions of controls and
their functions.
Although consoles have a fixed number of channels,
you are not limited to that number of sources. The RAQ
and DESQ control surfaces are laid out in a conventional
manner with the monitor and ancillary controls located
on the right side of the frame. Let’s look at each of these
sections in detail.
1. Channel ON Switch: The ON key toggles the
channel between the ON and OFF states. The channel ON and OFF functions also provide logic (start
and stop pulses, monitor muting, etc.) specific to the
source type.
For example, if a control-room mic is assigned to a
fader, the CR monitors and Preview speakers will
mute when that fader is turned on and when CR microphone sources are Previewed.
2. SOFT Key: Each channel has a Soft Key. The
OLED display tells you what function the soft key
is currently controlling. The default action depends
upon the type of input assigned to that fader, which
is defined in the Source Profile. Current functions
of the key are Mute, Talkback and phone hold. This
key is also used to exit Channel Options edit mode.
3. PREVIEW Key: allows the operator to listen
to sources before they air. RAQ/DESQ Preview bus
allows auditioning in full stereo. Individual source
profiles can change Preview to Solo (post-fader) operation.
The Preview key acts like a latching switch.
­ omentarily pressing any channel’s Preview key
M
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 can be interlocked: pressing Preview on any channel will remove any other channel
from Preview mode.
If you want to preview multiple channels, pressing
and holding any Preview key temporarily disables
the interlock; other sources can be added to the Preview mix by pressing them. Conversely, channels
can be removed from a multiple Preview selection by
pressing and holding any lit Preview key and deselecting the individual channels you wish to remove
from Preview.

Figure 3-1: DESQ
The interlock option for Preview can be disabled in
any Show Profile’s Monitor section so that users can
gang preview sources without the need to press and
hold Preview.
The audio from the Preview bus feeds any speakers
dedicated to Preview, and can also be routed to the
operator’s headphones and CR monitors if desired.
Preview speakers will be muted whenever and CR
microphone is ON, or is assigned to the Preview bus.
4. Channel Information Display: This OLED
display interacts with the Channel Options control
and the Soft key. It is context-sensitive and can display many different parameters relevant to each fader. Normally the display will show the name of the
source that is applied to the fader (“Zephyr”), and the
function assigned to the SOFT key (“TALK”).
When fader channel parameters are being edited, this display shows gain and pan settings,
mode, backfeed selection and other parameters that will be dependent on the type of source.
When viewing these menus, the Options control
is pressed to select the function, and rotated to set
the value.

Just below the Source name is a status line.
It shows the status of a channel. It is displayed in medium font. In the previous example, it is “[TALKBACK].”.
Here is a list of the different status displays and their
meanings:
»» [TALK TO CR] - means that this channel is talking to Control Room. Used on Guest Microphone
and Codec source types
»» [OP TALKING] - means that this fader is an operator mic and it is currently in use for Talkback
rather than feeding to Program buses
»» [MUTED] - means that this channel is muted
»» [TALKBACK] - means that this channel is being
talked to, i.e., the talk bus is fed to the backfeed
stream for this fader.
»» Src-label - If the source has an associated label, it will be shown. Source label is normally
used by playout systems to indicate song name
and/or important information. Available only for
Livewire sources.
»» Listen Only - The source was loaded in listenonly mode. No GPIO control is available for this
source’s originating device.
»» Used EW - The source is currently in use elsewhere and is in listen only mode. As soon as
source is freed, it will be automatically reloaded
in Full Control mode.
»» Src Load Err - An error occurred during
source loading. Re-load the source.
»» No Backfeed - An error occurred during backfeed allocation for the source. For example, no resources are available to allocate backfeed stream.
»» Src Waiting - means that a new source is waiting to be loaded. This state is accompanied by a
blinking OFF key. Turn the channel OFF to load
the new source.
5. Fader: The fader controls the volume of the
input source. There are two modes for the fader: fader-start and fader-normal:
• When the channel is used in fader-start mode,
pushing the fader all the way to the bottom of its
travel turns the module off, and sends appropri-
ate logic commands to source equipment. Moving
the fader up turns the channel on and sends logic
commands. In fader-start mode, the On button
act more as indicators of channel status; the On
key will not turn the channel on if the fader is at
the bottom of its travel.
• In fader-normal mode, the on/off status and
start/stop commands follow the channel ON/
OFF switch independently of the fader position.
6. Program Bus Assignment Keys: Each channel is assigned to any of the two output buses by
selecting any (or both) of these program bus keys.
Generally, PGM-1 is the main bus and PGM-2 is
used for production or other programming requirements. All program outputs are post-fader and post
on-off function.
The PGM-2 button also functions to assign a channel
to a special Phone bus that is used to send mix-minus
audio to any phone callers. These buses operate independently but simultaneously, allowing jocks plenty
of operational flexibility. The Phone bus is pre-fader
and pre-ON/OFF function.
»» PGM-2 bus audio output is post-fader, post-ON/
OFF.
»» PGM-2 Record bus audio output is post-fader,
pre-ON/OFF.
»» Phone bus audio is sent to callers pre-fader, preON/OFF.
7. Channel Options Control: This control
operates in conjunction with the OLED fader display. Pushing the rotary encoder selects OPTIONS
mode, displaying various choices on the OLED
beneath. Rotate to select the desired option, and
then push to “take.” Once an option has been selected, you can rotate the control again to adjust
the value of that parameter (if any). Press the Soft
key to exit.
In the QOR’s Web setup, you can also assign a default function to the rotary encoder. Doing so allows
adjustments to fader options, gain trim, input gain

8. Meter Key: This key toggles the Soft meter
(right side of OLED meter display) between PGM 2,
Phone mix, and Monitor.
9. OLED meter display: The display by default
shows PGM-1 meters and also display another selected meter. When selecting a show profile or making
changes to a volume property (Preview, Headphones,
Monitor), the right half of the display will provide
information to the user of the options or changes
made. When the display shows options, use the Preview knob to highlight an option and press the knob
in to take.
10. Profile Key: This key allows you to select
the active Show Profile from a group of four preconfigured profiles. The OLED display shows profile to select from. The Preview knob is used to
navigate this screen. To exit this screen, press the
Profile key. You can also push and hold the profile key for 5 seconds to reload the current profile.
11. Control Room Monitor Select Keys: This
group of keys selects the source that is delivered to
your control room monitor speakers. The operator
may select from PGM 1, PGM 2, or two pre-designated external sources. The external sources are typically used for off-air receivers and are specified in
the web page configuration.
External 1 and External 2 have another function, in addition to their normal
monitor-select action. If you press and
hold one of these keys for 2 seconds, you will see that
the meter OLED display and preview knob may be
used to assign a source on-the-fly to that specific External Input. Press Ext 1 or Ext 2 again to exit this
Select mode
12. PREVIEW Level Control: Adjusts the volume level of the Preview output connected to your
external powered PREVIEW speaker. Note that the
PREVIEW speaker will be muted whenever any CR
microphone is ON. The preview knob is also used when

PREVIEW in HEADPHONE Key:
The
H/P
key controls whether audio from the Preview
bus will be fed to the board op’s headphones, and if
so, in what manner. Pressing this key toggles through
the following options:
»» Off: The operator will not hear Preview audio in
the headphone ­channel.
»» ON (Stereo): audio from the Preview channel
overrides the Headphone Monitor selection
and is sent to both the left and right channels of
the operator’s headphones.

ON or when Record Mode is active
16. Clock Key (DESQ only): Pressing this key
toggles between AUTO and MANUAL modes for the
count-up timer. AUTO allows it to be reset and started
by any source starting that has it’s timer start option
enabled. MANUAL ignores those starts and follows
the RUN/STOP/RESET keys only. Note that even if
you are set to AUTO, the run/stop/reset keys still work.
To set the clock, push and hold the Clock key for 6
seconds to enter clock adjust mode. The Clock key
will illuminate indicating that clock setup is active.
Release the Clock key and press RUN-STOP to set
the clock display forward, and press RESET to set it
back. Press the Clock key again to save the current
time and exit clock adjust mode. If NTP is active and
enabled (via web page configuration), the time cannot be adjusted manually.
17. Event timer keys (DESQ only): The Reset
key and Run-Stop key control the count up timer as is
typical in a stop watch. Run-Stop starts and stop the
timer. Reset will set the timer back to zero value.

Control Room Guest Microphone Channel
There are often microphones in the Control Room
other than the board operator’s; i.e., an in-studio guest or
perhaps an announcer located physically near the board
op. These microphones also control the muting of the
Control Room monitor speakers.
Options available are:
»» IP Address
»» Subnet Mask
»» Gateway
»» Save and Reboot
Source-Specific Channel Controls
Some fader functions change their behavior to suit
the type of source assigned to the fader. A Guest 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.
Control Room Operator Mic Channel
The Control Room Operator microphone is the board
operator’s mic. It’s always located in the Control Room,
so activating a channel designated as the CR Operator
mic affects CR Monitor speaker and Preview speaker
muting.
When the board operator pushes a Talkback key, all
output bus assignments for the Control Room Operator microphone are temporarily muted, while his mic’s
audio is routed to the requested Talkback destination.
Releasing the key returns the channel outputs to normal.
Pressing the soft key for the CR Operator Mic while
the channel is already on will mute the channel until
the key is released, acting as a “cough” function for the
board operator. On-air status and speaker mutes are unaffected by this action. The CR Operator microphone
channel will mute the CR Monitors (Monitor 1) and the
Control Room Guest Microphone channels will mute
the Control Room speakers and the Preview speakers
whenever the channel is ON, or if Preview key is selected.
Line Channel
Line-level devices like CD players, 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 Pan & Mode Options
section.
Line channels have a variety of remote logic functions available at the GPIO interface. ON and OFF states
can be remotely controlled, as well as the Preview key.
Each function has a corresponding lamp driver.
Phone Channel
The Phone Channel profile is used, naturally, for telephone hybrid audio sources. Each Phone Channel has its
own discrete Feed-to-Source mix-minus output.
Each RAQ/DESQ can accommodate six automatically-generated mix-minus feeds (one per channel). If
the Feed-to-Source mode is set to “Auto”, (the most
common option - see Chapter 2: Inputs and Outputs
for the section entitled “Source Profile Options”), phone
callers hear the output of the Program-1 bus, minus
himself, when the channels they’re assigned to are ON.
When the caller’s channel is OFF, callers hear the output of Phone bus (Pre-fader, pre-ON/OFF of channels
assigned to PGM-2).
Phone feed-to-source outputs can also be locked to
backfeed only PGM-1, PGM-2 using the options provided when constructing the Source Profile for your hybrid.
©2014 Axia Audio - Rev 1.1.1
3: Console Operation • 27
The meter display shows the options and the preview
control is used to navigate, select options and change parameter values
This automatic switching mode makes it very easy to
prep callers and then seamlessly take them to air with a
minimum of key pushes.
Codec Channel
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. Codec Channels can be turned on and off remotely and provide on/
off status to a remote logic device. Remote Talk and
Remote Mute are also provided, allowing talent to take
control using their own On/Off/Mute/Talk panels.
Talk enables remote talent to communicate with the
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; the channel’s OLED
displays TALK to CR. When the user stops talking, the
channel returns to normal.
When the operator uses the Softkey to talk to the
phone or codec source, the OLED displays TALKBACK.
When the remote mute function is activated, the
OLED displays MUTED and all the channel outputs are
muted until the command is released.
Profile section) normally feeds Program-1 audio to the
remote, but can be switched to Program-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 Talkback audio
when the board op talks to the remote. The Right output
sends uninterrupted program audio (without talkback)
for use as a PA feed.
Remote Control
Console channels can be turned on and off remotely,
and will provide on/off status to a remote logic device.
Remote Preview is also provided, as are lamp drivers
for On, Off and Preview. Start and Stop pulses can be
sent when the channel is turned on or off, respectively.
See Chapter 5: Configuring GPIO for detailed information interfacing to GPIO inputs and outputs.
What’s Next
Now that you’re familiar with RAQ/DESQ controls,
let’s learn to tap the power of Show Profiles.

Show Profiles
If you’ve read Chapter 2: Inputs and Outputs, you
already have a good understanding of Source Profiles.
In the same way that Source Profiles allow you to determine how an individual channel is configured when
a source is loaded to a fader, Show Profiles let you build
configuration files that determine how the entire console
behaves, which sources are loaded, and what channels
they appear on — “snapshots” that you can load at will
to recall baseline show settings.
You can save and recall up to four unique Show Profiles to customize the RAQ and DESQ for different conditions.
Creating A Show Profile
Build A Show
QOR’s Web interface, which you’ve used to construct Source Profiles, is also used to help build Show
Profiles, so make sure a computer connected to your
QOR or Livewire network.
The first step in building a Show Profile is to set up
a RAQ or DESQ using the Channel Options, Monitor
and Headphone options as described in Chapter 3. Get
started by assigning a source to each QOR fader using
the Options knobs at the top of each channel.
After you’ve assigned a source for each fader, you
can configure the rest of the Channel Options:
• Gain,
• Pan / Balance,
• Feed to Source.
When you’ve configured all Channel Options, continue on and make monitor and headphone selections
since these are all saved in Show Profiles as well.
When you’ve got the board configured to your satis-
Capture It!
It’s now time to save your configuration as a Show
Profile. Enter your QOR’s IP address in your Web browser.
When the Main Menu appears, choose Shows on the
sidebar menu. This is where you’ll come whenever you
need to capture, construct or administer a Show Profile.
Under the Show Profiles list, you’ll find four profiles
listed with three options for each Show Profile:
• Edit. Choose this option to manually edit any existing show profiles.
• Capture. Takes a “snapshot” of the current control surface state and saves it for recall. This is the
option we’ll use in just a moment.
• Reset. Choose this option when you want to
construct an entire Show Profile completely from
scratch and reset all parameters to their default
state or value.
You’ve already set up your control surface, so now
you can just “capture” your settings for further use.
Choose Capture from the menu. You are allowed to
store four Show Profiles which are saved as A, B, C and
D. You may also give meaningful names to these Show
Profiles as described in the next section.
There may be a few more options you’d like to tweak,
since not all options are accessible from the console itself. Let’s go a little deeper into Show Profiles to find out
exactly what’s available to you.
Show Profile Options
Although the ability to create Show Profiles using the
“capture” function is powerful, there are a few more options available exclusively via the QOR Web interface.
You will probably find that a combination of console
setup, capture and edit works best.
When you select any Show Profile, you will enter the
edit screen as shown in Figure 4-2. Notice that there is
a section for the faders, as well as sections for Monitors

Fader Channels
4: Show Profiles • 30
This section has settings for each fader channel.
When this specific Show Profile is loaded, these settings
will be applied.
• SOURCE: You can change the source using the dropdown box. The name of the source you assign will be
displayed on the OLED below the fader.
• ON/OFF: Specifies the channel ON/OFF state when
the profile is loaded.
• PGM1/2: Determines the default bus assignments
for this channel when the Show Profile is loaded.
When a check-box is selected, the source will be assigned to the corresponding bus.
• Group Start: There are three possible settings:
»» Independent - this fader is not associated with
any other fader and operates independently
»» Master - is used to select one fader as the master
for group starts.
»» Slave - is used to select one or more faders as
Slaves that will follow the action of the fader that
has been designated as the Master.

Gain independently for CR Monitor, CR Headphones. This determines the amount of dimming that
will be applied when Talkback is directed to one of
these outputs. The default setting is -12.0 dB.
Mute Gain (-85..0 dB): You can specify the amount
of attenuation that takes place during a Mute function. The default is full mute. Mute can be applied
to CR monitor, Preview but it is not applied to CR
Headphones.

monitoring purposes plus one source that is an External Preview source. Note that the drop-down selector displays all sources that have been defined as
sources in the Source Profile manager.
Source:
What’s External Preview for? “External” refers here to any source not generated inside the
studio you’re working in. Let’s say you have a
Talkback source that you want to feed to the
console’s Preview speaker. To do this, you would
setup a source profile for the Talkback audio and
specify that source as External Preview

that even though these are general
settings, they are specific to each

is used
to specify the default timer
mode - manual or automatic.
In automatic, the timer may be
started by turning a channel ON.
Preview Interlock Mode: If
Enable is checked, pressing any
fader’s Preview key causes any
other, previously-lit Preview
key to be extinguished, removing that source from Preview.
The board operator can assign
multiple faders to Preview by
pushing and holding any lit Preview key while pushing other
Preview keys to add or subtract.
If unchecked, each Preview key
works like a press-on, press-off
latching switch. Multiple faders
can be assigned to Preview simply by pushing once; a second
push cancels any individual Preview assignment.
Switchable Meter Source: The second meter is
a “soft” meter. The desired default may be selected
from the drop-down menu. Choices are: Program 2,
Phone mix or Follow Monitor
Logic Port for Timer: Enter the Channel Number
of the GPIO port you wish to use for external control
of your Count-Up timer.
Talk to CR Level: Use up to -30 dB attenuation or
10 dB gain on the contents of the Talkback bus.
Control Lock Map: This section includes several
check boxes. When a box is checked, the selected actions are allowed. Any unchecked boxes will prohibit

Chapter Five:
Configuring GPIO
This chapter explains how to set up QOR GPIO. We
also invite you to read the GPIO Node User’s Manual,
for more in-depth information on the topic of GPIO.
GPIO Port Definitions
Axia GPIO ports can deliver unique command sets
for the following types of devices:
1.
Mic (Operator, Guest, Producer)
2.
Line Input
3.
Codec
4.
Telephone Hybrid
5.
Computer Playback Device
6.
Control Room Monitor
The next few pages contain tables that explain what
function the pins provide in each different device mode.
The QOR.16 has four DA-15 connectors and the
QOR.32 has 8 DA-15 on the back panel. Each connector (also known as a GPIO port) can be associated with
a device in your studio, and provides five opto-isolated
inputs and five opto-isolated outputs per device for machine control, lamp drives and remote channel controls.
GPIO ports can also be monitored and controlled by our
PathfinderPC software.
GPIO ports are programmed to support several different types of devices. How does a GPIO port “know”
which type of device is assigned to it?
If the Source Profile is a microphone, it tells the
GPIO Node to send logic for On, Off, Remote Mute
and Remote Talk commands on the appropriate pins. A
line input, the GPIO port sends Start, Stop and Reset
commands, plus closures for Ready lights, etc.

Back in Chapter 2, when you constructed a Source
Profile for a telephone hybrid, you defined the source
type (see “Adding Backfeeds and GPIO to a Source Profile”). This is important, because when that source is assigned to a console fader, this Source Profile selection
defines the GPIO port what sort of command to send to
the attached device.

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 Source Profile, all that
remains to do is to solder cables connecting the GPIO’s
DA-15 connectors to the device’s control interface.
So, how do you link a GPIO port with a Source Profile? It’s very easy; let’s do it step-by-step.
Note: This procedure assumes that you have
already defined at least one Source Profile using
the instructions outlined in Chapter 2.
1. Open your Web browser and enter the IP address of QOR. Choose GPIO Configuration from
menu. Enter your password if prompted (default login is “user”, leave the password field blank).
5: Configuring GPIO • 42
2. If you haven’t previously assigned any GPIO
ports, the GPIO definitions screen will be blank. Notice the status indicators at the top of the page, showing the state of the input and output pins of each port.
The “Logic for” option defines how the port will be
used.
»» LWRP: The port will only be controlled through
a control protocol. Software packages, as in Pathfinder use the protocol.
»» LIVEWIRE: Specify a channel number and the
port will follow the logic associated with that
channel (this will be used for CR monitor logic)
»» SPECIFIED INPUT: Define an input port and
the port will follow the logic of that input.
Figure 5-2: GPIO Select Source popup list
3. If using the LIVEWIRE option, you will need
to specify the Channel Number in the Livewire
Channel column. You can do this by manually entering the number, or browsing the network for an
advertised Livewire channel. When you click on
any list icon, a small popup window will open, enumerating all of the audio sources available on the
Livewire network (Figure 5-2). 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.
If you’re using a local source, specify the input. If a
source profile has been created to control a phone
hybrid using Analog 5 as the input, select Analog 5
in the drop down list. The functions of the GPIO port
will now follow those shown in the Hybrid Logic
Chart.
4. Type a descriptive name in the Name field, and
click on the Apply button.
Figure 5-3: Pin status indicators showing
GPIO port activity
Figure 5-1: GPIO Port Assignment
5. 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 5-3.
©2014 Axia Audio - Rev 1.1.1
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
send the appropriate logic commands to that port when
the source is assigned to a channel.
Connections to GPIO Ports
Input Connections
Current on these inputs must be limited to 20 mA or
less, through the use of a current-limiting resistor. An
external power source (24 volts DC maximum) is recommended for all inputs and outputs, to prevent ground
loops between equipment. However, if customer equipment is completely isolated, using power from the GPIO
port connectors is acceptable. Figure 5-4 shows details
for both types of connections:
Figure 5-4 GPIO input connections
©2014 Axia Audio - Rev 1.1.1
5: Configuring GPIO • 43
Referring to the Hybrid Logic Chart, we can see that
when the 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 becomes active.
Output Connections
The GPIO port’s outputs are opto-isolated. Current
should be limited 100 mA through each output, with the
total current draw from the +5 Volt supply not to exceed
3 amps. Figure 5-5 shows the recommended connections
for outputs:
5: Configuring GPIO • 44
NOTE: Some external devices will allow a logic
control input “sink to ground” to activate. Thus,
some devices may not work with an Axia GPO
control, because they may not fully achieve
ground through the output transistor. The voltage drop between the collector and emitter may
not be low enough to activate the device, so an
external relay controlled by the GPO may need
to be used to provide a “dry” contact closure to
the external device.
Please note that this section is provided as a “jumpstart” introduction to Axia GPIO nodes. For a fuller
understanding of the GPIO node’s options and requirements, you may wish to read the GPIO Node User’s
Manual.
Virtual GPIO
Virtual GPIO ports allow you to to avoid having to
wire a GPO pin to a GPI pin in order to achieve a particular function. The Virtual GPIO ports provide an ability to
define up to five GPO pins that can be “virtually wired”
to a single GPI pin. Typically this is used in cases where
you want a GPO function to trigger a different GPI function. Please refer to the GPIO tables to determine what
those functions are.

The QOR Control Center
6: Advanced Controls • 46
Figure 6-1 shows the screen that greets you when you
log into your QOR from your Web browser. The main
menu runs down the left side and gives access to options and settings. In the main window you can see at a
glance what version of QOR software is loaded, system
information, CPU statistics, and more. For diagnostic
purposes, this information screen is openly accessible,
but clicking on any menu heading will prompt you for
a password. Here you’ll find options related to the QOR.
The Status Screen
The Status screen is your home page. It displays basic system status as well as information pertaining to the
active software load. A sample of this screen is shown
in figure 6-1. Additional information displayed may include:
• QOR software version info including the current active Version and Base
• System Information including:
»» Version of Linux kernel
»» Uptime of the QOR expressed in days, hours and
minutes
»» CPU utilization
»» Network Information
»» Debug information
• File System Information - provides information on
memory and solid state disk utilization for the operating system. This information may be requested by
Axia tech support.
The Setup Menu
We touched briefly on the IP features of the Setup
screen in Chapters 1 and 2. Now let’s look at the rest of
the tools on this page shown in Figure 6-2.
• Network Configuration contains the fields for the
QOR IP Address and other network functions.
»» Hostname is the unique name you give the console to identify it in the Web interface. You might
want to name it after the studio it’s in.
»» IP Address: This is the network address of your
QOR. We suggest that you have a plan to ensure
that all of your Livewire devices are assigned
unique, IP addresses.
Shortcut Key: You can also set the IP address
of your QOR by pressing and holding the Meter key on the Console. Use the Preview knob
to navigate and follow the prompts to give your
QOR a new IP address.

packages currently stored on your QOR flash
memory card. The blue radio button is displayed
next to the active software image.
»» Change Active Bank: When you want to
change the active software package, click on the
radio button next to the image you wish to activate, and click this button. A reboot is necessary
to load the new software choice.
»» Upload Image: From time to time, Axia makes
new software packages available for download from AxiaAudio.com/downloads/. Use the
Browse and Upload Image buttons to install
new software, as described in the Technical Bulletin that accompanies each software release.
Note that uploading a new image will always
over-write the inactive bank.
»» Reboot shuts down QOR and restarts it. A reboot is required after changing active software
or after changing any settings in your Network
Configuration.
»» Netmask: Enter your network’s submask here.
If you are not sure about this - consult your network administrator. In most cases a Netmask of
255.255.255.0 is suitable.
»» Gateway: If you have a Core switch or a network gateway to allow access from outside your
facility, enter that address here. A gateway is required for advanced IP address configurations
and for connection to an external NTP server.
Note: A reboot is required when any changes
are made to the network parameters on the
QOR Setup Menu.
•
By default, the user name
is set to “user” and the password is blank. If you
want to add a password, type it in both boxes and
click Change. Note that passwords will not display
here once changed, so be sure to make a record of all
password changes.

Web Access Password:
Save your work! We recommend backing
up your Configuration files whenever a major
change is made, or is about to be made, to your
QOR. Whether you are re-configuring Show or
Source profiles en masse or about to perform a
software update, it’s always a good idea to have
a copy of your important data.
The Customize Menu
The Customize page contains Clock settings and
Backup/Restore functions. Future enhancements may
include additional features in this area.
Figure 6-2: Setup Screen
Clock Options (DESQ)
»» Clock Format: This is where you define whether
you will view your time in 12 hour or 24 hour format.
DESQ surfaces can use either the internal clock
or an external time server for timekeeping. The
next group of settings will set up NTP (Network
Time Protocol) time sync.
»» Time Zone Offset: Specify your local GMT
offset in hours and minutes. For example, if you
live in the Eastern Tome zone in the USA, your
GMT offset will be -5 hours, 0 minutes. If you

live in Riga, Latvia, your offset will be +2 hours.
»» DST in effect (+1 hour): In those area that implement Daylight Savings Time, this check box
is used to tell your system to add one hour to the
GMT offset.
»» NTP: The check box should be checked if your
DESQ’s NTP clock sync function is enabled.
To disable NTP service, simply un-check this
box. The other box here is used to enter the
IP address of your external NTP server. This
server may be a PC on your local network or
it may be the IP address of a public NTP server in the Internet. Note that you must specify an IP address – a URL will not work.
If you wish to connect to a public or external
NTP server, be sure to specify a valid Gateway
in your IP configuration.

This is an extremely important area
of your QOR configuration since this is where you
will backup all of the hard work you have done.
»» Backup Settings: All QOR settings can be saved
in a single operation and backed up to a location
on your local drive. When you select the Backup
option, you will see the familiar location navigator
that prompts you for the folder in which you wish
to store your backup file. The backup file will be
named according to the device name, IP address
Configuration:
Log, Log History and Log Setup Menus
QOR keeps a detailed log of user actions and other
system events. Choosing the Log menu item lets you examine the last 100 logged activities; choosing the Log
History menu item allows you to view an entire day’s
log at one time and delete old log files if you choose.
The oldest log files are deleted automatically as storage
space dictates.
The Log Setup menu item allows you to specify an
external Syslog server and to configure the debug level.
This menu also allows you to specify from eight different severity level filters. The filter choices (in order of
decreasing severity) are:
• Emergency: system us unusable
• Alert: action must be taken immediately
• Critical: critical condition
• Error: error conditions
• Warning: warning conditions
• Notice: normal but significant condition
• Informational: informational messages
• Debug: debug level messages
Use this section as directed to do so by Tech Support.
The Module Manager
The Module Manager heading displays information about the control surfaces connected to your QOR.
Some of these fields are for diagnostics; below is a list of
those you might find useful:
»» Address: displays the number Axia has assigned
to each connected unit.
»» Type: gives you the working name of the module.
»» State: tells you whether or not the module is
working, i.e., communicating with the CPU.
»» Ping: Indicated ping response in ms.

NOTE: Updating a module takes it offline during
the update process. While audio playing through
the module’s faders will continue uninterrupted,
keep in mind that while updating (usually about
5-10 seconds) you will not be able to adjust gain
or turn faders on or off on the module being
updated.
GPIO Configuration Menu
This menu is where you configure the assignments
for the opto-isolated GPIO connections found on the
rear panel of the QOR. For a thorough discussion of
this screen and how to configure GPIO, please refer to
Chapter 5: Configuring GPIO.
Remote
The remote function available through the web interface gives you many of the same controls that are on
the surface:
• You have the option to load a Show profile by selecting the show in the dropdown selector, and then
pressing the Load button.
• Each fader channel is shown with an option to change
the source, change the ON state, assignments to the
mixes, and Preview state.

Brightness Control Menu
This menu offers several options for setting the control surfaces to your studio’s ambient lighting. All values are expressed in percent. The default setting will be
suitable for most studio environments, however you may
make adjustments as needed.
NOTE: The SFP (small form-factor pluggable)
slot is intended for utilization of fiber connections. In parallel are copper 1 Gbps ports. These
ports are used for connections to other QORs or
to a network switch. The remainder of ports are
100 Mbps ports for your Livewire enabled devices. Four of the ports also include PoE (Power
over Ethernet) which can be used to power devices that utilize this technology.

Chapter Seven:
Selecting the Source Input
Networking with QOR
Axia invented networked audio for broadcast. We
call it Livewire, and QOR uses this networking ability in
several different ways:
• A RAQ or DESQ surface can load and utilize
sources from other studios connected to your
Livewire network.
• You may deliver DSP outputs from your QOR to
the Livewire network for use by others.
• QOR can also use GPIO logic that is available
on your Livewire network.
• The Livewire network allows you to use our
companion software package, PathfinderPC, for
numerous advanced functions.
• Up to four QOR engines can be configured daisy-chain style, without the need for an external
core Ethernet switch, to take advantage of network redundancy provided by implementation
of the Spanning Tree Protocol (STP) standard.
• Manage control surfaces remotely using its web
browser interface.
• Configuration backup and restore operations
may be performed over the network as well.
Chapter 7: Networking with QOR • 52
with 12 lanes coming towards your studio and 4 lanes
going out (or 8 and 8).
In Chapter 2: Inputs and Outputs, we discussed
the QOR’s local inputs - those associated with the XLR
and RJ-45 connectors on the rear panel. We saw how
we could associate each of these physical inputs with a
Source Profile. The type of source (CR mic, Guest mic,
codec, phone, etc) determined parameters such as monitor muting and backfeeds.
When each Source Profile is configured, you have
a choice for the Source Input. If you select one of the
rear panel connectors, the console source is associated
with that input. If you select Livewire, you are telling
For an in-depth discussion of Livewire, please
review our publication “Introduction to
Livewire: IP-Audio System Design Reference and Primer,” which provides an excellent
discussion of IP-Audio and how standard Ethernet can be used to transport real-time broadcast audio in a studio environment. This is available at ­­A xiaAudio.com/­manuals/.
Inputs
When connected to a network of devices, the QOR
has access to these other resources.
QOR has a configurable gateway of 8-in and 8-out
(8x8) OR 12-in and 4-out (12x4) Livewire channels with
a larger network. To understand this, it might help to envision this network connection as a high-speed freeway,

Figure 7-1: Codec Source
the QOR that this source is not associated with a local
input but is, instead, a source from elsewhere on your
Livewire network. You may then assign that Primary
Source by using the Browse button to choose from a list
of Livewire sources. That’s all there is to it!
Figure 7-1 shows an example of a codec source
that’s been configured as a Livewire Source Input with a
network Primary Source. In this example, the Livewire
Channel Number of that source is 1037 and it is coming
from an Axia node named AES-103. The source has a
designation of CODEC_1 on that node. Everything else
in the configuration of the Source Profile is exactly the
same as if that codec was connected directly to the QOR.
Networking
Outputs
The Output configuration of the QOR has two sections: one for Local Outputs (rear panel connectors)
and one for Livewire Outputs. As you might expect, the
Local Outputs are usually configured for feeds to in-studio devices like CR Monitors, headphone amplifiers, etc.
The Livewire Outputs consist of four streams
(12x4) or eight streams (8x8) from the QOR to your
Livewire network. These streams will be available to
other devices and users on your network.
The following parameters are configured for each of
the Livewire Outputs:
• Output: Specifies the audio feed to be delivered to
the network on each of the Livewire channels. Selec-
To deploy QOR in a network setting, you will interconnect the Ethernet switch built into your QORwith
other QORs, or to external Ethernet switches. The custom Ethernet switch integrated into the QOR differs
from an off-the-shelf network “core” switch in the following ways:
• The Ethernet switch in an QOR is always at the “edge”
of a large Livewire network. In IT parlance, this type
of switch is actually referred to as an “edge” switch.
• If you have a large Livewire LAN, you will usually
have a central, high capacity, managed switch that
handles all of the connections from your “edge” devices, including QOR switches. This central switch
is referred to as your “core” switch. Common core
switches include the Cisco 3750, 4948 and some of
the 6400 series switches. The core switch is often
completely populated with 1000BT ports.

or digital AES inputs.
»» Any internal generated QOR sources including
PGM-1, 2, CR Monitor, CR Headphones, Preview,
Talk to CR, Talk to External, and Auto Backfeed.
»» VMix or VMode outputs.
• Name Override: Allows you to specify a name (16
characters maximum) that will describe this QOR
source to network users. This field will override the
source name specified in the local Source Profile.
• Channel: The Livewire channel designation. Specify a unique channel number between 1 and 32,767
that will be used by the Livewire network to identify
your QOR’s network audio.
• Mode: Enables and chooses the stream priority for
this channel. Options are:
»» Disabled - the channel is off.
»» Live Stereo - Choose this when the audio output
contains live voices or other high-priority audio.
»» Standard Stereo - Choose when the audio output consists of pre-recorded music or programming.
Chapter 7: Networking with QOR • 54
IT Note: If your system employs an Ethernet
core switch, the Ethernet core switch must have
an IP address numerically lower than any of
your QOR units or Ethernet edge switches. This
function of the IGMP standard ensures that the
multicast querier is handled by the core switch
if one exists. The querier function will be passed
off transparently to another switch should the
core switch fail or be disconnected.

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, Elements, StudioEngines, PowerStation, 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.
Livewire systems can support over 10,000 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 is 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.
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: IP Audio System Design
Reference and Primer.

A logical convention that is often followed will link the Livewire channel number to the last octet of the device IP
address. For example, if a node has an IP address of 192.168.1.12, the channel numbers assigned to the 8 sources of
that node might be 1201 through 1208.

Warranty
Telos Alliance Limited Warranty
This Warranty covers “the Products,” which are defined as the various audio equipment, parts, software and accessories manufactured, sold and/or distributed by or on behalf of TLS Corp. and its affiliated companies, collectively
doing business as The Telos Alliance (hereinafter “Telos”).
With the exception of software-only items, the Products are warranted to be free from defects in material and workmanship for a period of five (5) years from the date of receipt of such Product by the end-user (such date of receipt the
“Receipt Date”). Software-only items are warranted to be free from defects in material and workmanship for a period
of 90 days from the Receipt Date. Telos will repair or replace (in its discretion) defective Products returned to Telos
within the warranty period, subject to the provisions and limitations set forth herein.
This warranty will be void if the Product: (i) has been subjected, directly or indirectly, to Acts of God, including
(without limitation) lightning strikes or resultant power surges; (ii) has been improperly installed or misused, including (without limitation) the failure to use telephone and power line surge protection devices; (iii) has been damaged by
accident or neglect. As with all sensitive electronic equipment, to help prevent damage and or loss of data, we strongly
recommend the use of an uninterruptible power supply (UPS) with all of our Products. Telos products are to be used
with registered protective interface devices which satisfy regulatory requirements in their country of use.
This Warranty is void if the associated equipment was purchased or otherwise obtained through sales channels not
authorized by Telos.
EXCEPT FOR THE ABOVE-STATED EXPRESS WARRANTY, TELOS MAKES NO WARRANTIES, EXPRESS OR IMPLIED (INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE).
In order to invoke this Warranty, the Product must be registered via Telos’ website (found at: http://telosalliance.
com/legal/warranty) at time of receipt by end-user and notice of a warranty claim must be received by Telos within
the above stated warranty period and warranty coverage must be authorized by Telos. Contact may be made via email:
[email protected] or via telephone: (+1) 216-241-7225. If Telos authorizes the performance of warranty
service, the defective Product must be delivered to: Telos, 1241 Superior Avenue, Cleveland, Ohio 44114 or other
company repair center as may be specified by Telos at the time of claim.

Warranty • 69
In no event will Telos, its directors, officers, employees, agents, owners, consultants or advisors (its “Affiliates”),
or authorized dealers or their respective Affiliates, be liable for incidental or consequential damages, or for loss, damage, or expense directly or indirectly arising from the use of any Product or the inability to use any Product either
separately or in combination with other equipment or materials, or from any other cause.
Shipping Costs and Warranty Service:
If the date the customer’s notice of warranty claim is received by Telos (such date the “Warranty Claim Notice
Date”) is within the first 90 days following the Receipt Date, Telos will pay the costs of shipping such warranted Product to and from the end user’s location, and the cost of repair or replacement of such warranted Product.
If the Warranty Claim Notice Date occurs after the first 90 days following the Receipt Date and before the end of
the second (2nd) year, the customer will pay the freight to return the warranted Product to Telos. Telos will then, at its
sole discretion, repair or replace the warranted Product and return it to the end user at Telos’ expense.
If the Warranty Claim Notice Date occurs between the end of the second (2nd) year following the Receipt Date
and the completion of the fifth (5th) year, the customer will pay the costs of shipping such warranted Product to and
from the end user’s location. Telos will then, in its sole discretion, repair or replace the warranted Product at Telos’
expense. Telos also reserves the right, if it is not economically justifiable to repair the warranted Product, to offer a
replacement product of comparable performance and condition direct to the customer at a discounted price, accepting
the failed warranted Product as a trade-in.
The end user will in all cases be responsible for all duties and taxes associated with the shipment, return and servicing of the warranted Product.
No distributor, dealer, or reseller of Telos products is authorized under any circumstances to extend, expand or
otherwise modify in any way the warranty provided by Telos, and any attempt to do so is null and void and shall not
be effective as against Telos or its Affiliates.
Warranty • 70
Out of warranty units returned to the factory for repair may be subject to a $500 evaluation fee, which fee must
be prepaid prior to shipping the unit to Telos. If no repairs are required, the $500 fee will be retained by Telos as an
evaluation charge. If repairs are required, the $500 fee will be applied to the total cost of the repair.
