Matrix-Free IP Networked Intercom
The Telos Alliance are leading experts in Audio Over IP (AoIP) and introduced the first integrated AoIP protocol, Livewire™, in 2003. Livewire™ has since become Livewire+™ AES67, an AES67 compliant, interoperable standard AoIP protocol. that is the only one of its kind to meet all qualifying criteria of the AES67 specification. Livewire+ provides source advertisement, GPIO control, advanced device control, and broadcast-quality audio, as well as AES67 compliance at 1 ms packetization.
Taking innovation one step further, Telos has now completely removed the centralized matrix for intercoms of any size. The Telos Infinity IP Intercom, leveraging off-the-shelf IT networking solutions such as managed Ethernet switches and routers, combined with high speed digital signal processing, has delivered an intercom system that is fully distributed and resilient.
There are no single points of failure and Infinity takes broadcast resilience to new levels. Furthermore, Infinity is completely flexible and expandable. Using 1000BaseT Ethernet, each Infinity intercom Panel can perform more audio processes than would be feasibly required in most broadcast applications.
As there are no additional matrix cards to buy and configure. Expanding the intercom simply requires the addition of Infinity intercom panels, virtual ports, or beltpacks to the network. User configuration is a matter of setting the IP address of the panel using the panel’s own keys, and using the Infinity Dashboard’s drag-and-drop interface to configure the panel. Dashboard can run as an MS Windows app or a Docker container under Ubuntu or AWS Linux. is a simple task of setting up the preferences using the panels menu mode and contact keys, or with the intuitive drag-and-drop Dashboard Windows-10 optimized software.
Integration is key to all Telos Alliance products. Consequently, the Telos Infinity IP matrix-free intercom is completely compatible with other Livewire+™ AES67 devices in the Telos Alliance range. Furthermore, any third-party devices that are AES67(or SMPTE2110-30 Profile A) compliant can exchange audio with Infinity directly. For example, an Axia mixing console can be used to create a mix-minus that will appear as an input directly in the Dashboard software allowing Infinity to easily create IFB circuits available to all Panels and Beltpacks. Furthermore, any AES67 compliant audio flows from 3rd party devices will work are presented as native parts of the Virtualized system I/O and can form part of the communication ecosystem.
This manual is designed to help readers new to AoIP to understand the basic concepts needed to make Infinity work. quickly over an IP network. The Dashboard software section takes the reader through a step-by-step process of configuring a simple system, demonstrating the basic concepts required to quickly configure a Telos Infinity IP intercom solution.
