Chapter Seven:
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 dai-
sy-chain style, without the need for an external
core Ethernet switch, to take advantage of net-
work 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.
For an in-depth discussion of Livewire, please
review our publication “ Introduction to
Livewire: IP-Audio System Design Refer-
ence and Primer, ” which provides an excellent
discussion of IP-Audio and how standard Ether-
net can be used to transport real-time broad-
cast audio in a studio environment. This is avail-
able at AxiaAudio.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 en-
vision this network connection as a high-speed freeway,
with 12 lanes coming towards your studio and 4 lanes
going out (or 8 and 8).
Selecting the Source Input
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 moni-
tor 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
