AVB Networking Guide
Network Switches
Two PreSonus SW5E AVB network switches will be added to the network.
One switch will be used exclusively for the EarMix 16 Personal Monitor
mixers so that all four devices can be powered over Ethernet. This
system also utilized the network switch built into the NSB-series stage
boxes to facilitate greater connectivity with fewer components.
Recording System
A computer is connected over USB to the StudioLive 24 at
Broadcast position to record up to 40 sources. StudioLive Series
III mixers include both Capture and Studio One Artist.
Wireless Router
A wireless router will be added to provide a LAN control network for
devices running UC Surface and QMix-UC. Please visit www.presonus.
com for a list of recommended wireless routers. Configuration tutorials
are available at www.presonus.com/learn/technical-articles.

Network Connections
Before beginning any Network configuration, it is highly
recommended that you follow the following best practices:
•
Draw It. Just like when you create a complex analog audio system,
when you begin creating an AVB network, we recommend creating a
diagram on paper, before you start connecting equipment. Not only
will this provide you with a map from which to work more efficiently,
it will also save you hours of cable tracing later should something go
wrong, because you’ll know where all the Ethernet cables are going.
•
Label it. Sure you think you’ll remember that your Front-of-House console
is connected to AVB port 2 on your switch and port 5 of your LAN router,
but best to be safe and label the cables at both ends, just to be sure.
•
Place it. Place your gear where it needs to be located before
you connect any cables, especially if you’re making your own.
This will save time when you’re running cables later because
you know you’ll be running them to the correct location.
•
Stretch it. Always leave a little slack in your cable runs. Ethernet
cable is not like analog cable in that it is not subject to the signal
degradation that comes from long cable runs. This will provide
you with some flexibility and room to adjust in the future.
In the diagram that follows, each component is connected to the AVB
network utilizing a modified star topology with the NSB-series stage boxes
and StudioLive 24R attached using a daisy-chain topology. It should be noted
that this system leaves room for stage expansion because of the AVB Thru
ports available on each of the EarMix 16M personal monitor mixers. These
connections could be used for additional components that don’t require PoE.
A separate LAN network has been created to remote control the three mixers
using UC Surface and QMix-UC. It should be noted that any wireless device
connected to the wireless router and running UC Surface or QMix-UC can
be connected to any or all three mixers. Because of this, it is important to
manage your user permissions.
For more information on User Permissions,
please review the UC Surface and QMix-UC Reference Manuals
