AoIP option - Owner's Guide

Introduction

What is AoIP?

Audio over IP (AoIP) is a technology allowing audio transport on internet (IP) networks. StormAudio has developed a new AoIP optional module that uses an AES67 protocol to communicate between sources and destinations.

StormAudio AoIP option

With this option, your ISP becomes an AES67 device able to receive and transmit AES67 streams.

The AoIP module can manage up to:

  • MK1:

    • 16 channels input and 32 channels output

  • MK1.5/MK2/MK3:

    • 32 channels input & output

It means that 32 AoIP audio devices can be connected to the ISP and the same number of sources can be received for MK2&MK3 (16 for MK1).

The option is able to manage both input and output streams at the same time.

Owner’s guide contents

This documentation will describe how to configure the module as well as create and manage streams (input and output) between devices, including some specific user cases such as Dolby Cinema server interface.

For information about how to install the module in your ISP, please use the installation guide included with your purchase.

Recommendations

Network

The AoIP option has two Ethernet ports:

If the WiFi network is planned to share the same local area network (LAN) as the installation network, we recommend using an independent LAN with a DHCP server for the AoIP devices, disconnected from the internet network and dedicated to the AoIP only. AoIP can quickly overload a WiFi network as it uses a quite large bandwidth.

When using a common network, installer must ensure that the equipment used will allow for enough bandtwidth, 1Gbps speed being a minimum requirement when managing a high channel count number.

Using a reliable and dedicated switch will ensure more versatility to the AoIP system and stability to the AoIP streams.

In simple setups, you can directly connect your AoIP device to the ISP’s AoIP option primary port using a single RJ45 cable.

AES67

The AES67 standard recommends streams of 8 channels, you can define up to 4 streams in the ISP. Generating more streams could affect the reliability of the option.

AoIP option configuration

This section covers a general guideline on how to configure your AoIP option to an AoIP network. In each specific step and in its related documentation, you will find information on specific use cases. One which is of particular interest for Home Cinema is the integration within a Dolby Cinema DCI server/player ecosystem. See the configuration example below.

Prerequisites

Your ISP should already be configured to match the speaker layout in your room and preferably connected to a network to configure it through its WebUI if needed. Keep the unit running.

Connect using an Ethernet cable (Cat 5e or above), plug it into the primary RJ45 port of the AoIP module on the back of the ISP, then connect the other end of the cable to your dedicated AoIP network. The network should be running a DHCP server for the first connection.

Typical configuration steps

  1. Connect the ISP’s AoIP option to the AoIP network. Enter the option’s WebUI to configure it. See https://support-stormaudio.atlassian.net/wiki/spaces/SUP/pages/309428278.

  2. Connect AoIP sources to the ISP’s AoIP network. Configure connections between the sources and the ISP and check that they’re working properly. If no AoIP source is used in the system, skip this step. See https://support-stormaudio.atlassian.net/wiki/pages/resumedraft.action?draftId=309592160.

  3. Connect AoIP destinations to the ISP’s AoIP network. Configure connections between the ISP and the AoIP device. Add one audio output device at a time and check if it is working properly before connecting the next device. See https://support-stormaudio.atlassian.net/wiki/spaces/SUP/pages/309428379.

Configuration example

Below are the steps for a Dolby server configuration to AES67 output devices through the ISP’s AoIP:

  1. Connect the ISP to the AoIP network and turn it ON.

  2. Connect the Dolby server to the AoIP network and turn it ON.

  3. Configure the connection between the Dolby server and the ISP.

  4. Connect an AES67 receiver to the network and turn it on.

  5. Configure the connection between the ISP and the AES67 devices.

  6. Repeat steps 4 & 5 for every speaker/amplifier you have to connect. Adding devices one by one helps to ensure relibaility to avoid problems further down the configuration process.
