IP Audio Routing & Mixing System
Start Up Guide
Below is shown a simple Primary connection only, (without redundancy) network example to show how to get a system working.
This is only shown to make it easier to understand how it works. A real world example system connection is shown in section 12.
Note:- All the Primary Audio Connections in the system need to be on the same subnet by default the
192.168.30/24
subnet.
This includes the Audio Network Switch which will need to be configured with a VLAN accessible over a number of ethernet
ports
The audio network switch shown below connects to the following:-
The Router on the Core :- to pass audio and control data to and from the AoIP devices.
The Connect application on the Core :- so that it can configure the AoIP devices.
The AoIP Device Primary connection :- to pass audio and control to and from the Core.
The PTP clock on the Core :- to provide synchronisation. between Core and AoIP device.
The PC :- so the user can setup the system via the Connect application.
A SIMPLE EXAMPLE OF CONNECTING A COMBO AOIP BOX DEVICE TO AN IMPULSE CORE VIA A PTP SWITCH
10. CONNECTING THE AUDIO SWITCH AND AOIP DEVICES TO THE CORE
Once all the connections are made, type 172.29.1.21 or 192.168.30.100 if connected to the Audio Subnet in the
Google Chrome address bar on and press enter to navigate to ‘ Connect ’ .
Walk through all the steps in Section 9 of this guide and the system should then be ready to test.
Note:
Please refer to
“AoIP Devices - Network Interfaces - Suggested Settings” on page 43
of this document for
suggested settings and reference tables. When adding more AoIP I/O devices it is recommended to add them to the
system one unit at a time to ensure that the IP addresses don’t overlap.
Once all the AoIP devices & AoIP core network interfaces are known to be set with unique IP addresses, they may all be connected to
the same network. All AoIP devices and the Core in the same subnet should be discovered and displayed in
‘Connect’
.
Please refer to the Further Reading section at the back of this guide for links to additional guidance about using Connect.
After completing the required steps, a simple system test can be made, where a Mic Input is patched to a transmitter stream, in the
AoIP Device, which in turn is networked to a receiver in the core. That receiver is patched using Console PC to an input channel on
the console, which will then be available on the Console. The Input channel is then routed to a Main Bus Output and patched to a
transmitter stream in the core, which in turn is networked to a receiver in the AoIP Device. Finally that receiver is patched to a Line
Output. If the setup is correct then the Audio Mic Input should be heard at the Audio Line Output.
