Updated: Oct 16, 2019

From the company that invented AoIP for broadcast

Telos Infinity is a new AoIP solution that delivers a quantum leap in scalability, ease of integration, efficiency and total cost of ownership. First in the new series of Telos Infinity solutions is the revolutionary Telos Infinity IP Intercom – a comprehensive next generation communications solution featuring: 

- Seamless interoperability through standards-based Livewire+ AES67

- Infinite scalability for all internal and external communications

- Plug and play device integration

- Intuitive UI for simplified operation

- Matrix-Free distributed network architecture

- Lower TCO than traditional intercom systems - Optimization for broadcast communications

Rethink Intercom

Telos Infinity IP Intercom is a complete reimagining of broadcast communications technology developed by the Telos Alliance engineering team that invented AoIP for broadcast in 2003. More than just a talkback system, Telos Infinity IP Intercom converges voice communication and contribution audio on a single IT backbone employing the latest standards-based VoIP and AoIP transport to provide dedicated features and functionality without compromise or limitations.

Break the Matrix

Telos Infinity IP Intercom replaces outmoded matrix technology with an advanced, distributed IP network solution that provides superior functionality in a simplified, more elegant form. Being matrix-free allows plug-and-play networked hardware and software devices to be added to the system as part of a planned or ad-hoc change, without ever worrying that you might exceed the number of available ports on a matrix.

As Part of an Integrated System…

Telos Infinity IP Intercom unleashes the full potential of a distributed IP audio infrastructure, allowing access to any networked audio endpoint through the intuitive Telos Infinity Dashboard application. Mix-minuses, program busses, mixer auxes, monitor feeds, remote contribution audio, and presenter mics are all available anywhere you need them - for communication or on-air use.  And since Telos Infinity IP Intercom natively supports Livewire+ AES67, it can be used with our own AoIP products or those from other supporting manufacturers.

… Or as Part of a Legacy Installation

Realizing the benefits of Telos Infinity IP Intercom doesn’t mean abandoning existing audio infrastructure. Instead, Telos Infinity seamlessly integrates into analog, AES, SDI, and MADI systems using Telos Alliance xNode baseband-to-IP interfaces and other AES67 partner devices. A transition to AoIP reduces the amount of cabling and its associated costs, system design time and installation expense - all while establishing a pathway to a complete AoIP solution in the future.

Infinite Possibilities

Telos Infinity IP Intercom marks the next generation of Audio over IP solutions destined to revolutionize broadcast communication through the creation of disruptive and innovative technologies - and it’s just the start. More functionality, features and new products are just around the corner.

Award Winning

We’re honored that Telos Infinity IP Intercom has been the recipient of several awards since its introduction at IBC 2017, including TVB Europe Best of Show (IBC 2017), Radio World Best of Show (NAB 2018), TV Technology Best of Show (NAB 2018), and AV Technology Best of Show (InfoComm 2018).


The Telos Infinity BP-2 is a next-generation wired Dual Channel Digital Beltpack that is powered by PoE (Power over Ethernet) and is natively AES67 compliant. Whether via Partyline, Group, IFB, Peer to Peer, or connection to any other IP audio networked element within the wider Telos Infinity IP Intercom, the Infinity BP-2 communicates across the network seamlessly while maintaining incredibly low latency.

Multiple INF-BP-2’s can be daisy chained together, powered from the same physical PoE port, providing a functionally superior alternative to traditional 2-wire or digital audio based partyline systems.

By combining familiar hardware Intercom facilities with the flexibility and workflow advantages of matrix-free IP communications, the INF-MP-16 sets a new benchmark in broadcast talkback technology. The INF-MP-16 1RU Intercom Master Panel features 16 multicolor talk/listen lever display keys that can show up to four lines of text plus bitmap images and icons (coming soon). Complemented by optimised voice channels and loudspeaker reproduction, the INF-MP-16 features the excellent speech intelligibility required for mission critical broadcast operations. 

Auxiliary, rear panel stereo analog I/O including a studio quality mic pre-amplifier, means that the INF-MP-16 can be used as a contribution or monitoring endpoint. The addition of GPIO as standard enables remote control of signalisation or complex logic interfacing across the network infrastructure.

For use in locations where a rackmount panel isn’t practical, the Telos Infinity INF-DS-16 16 Key Intercom Master Desktop Station delivers the same functionality and features as the INF-MP-16 in a compact and attractive format.


Telos Infinity Dashboard is unlike other Intercom system management tools. By displaying the entire Intercom system as a single page view without the clutter of multiple tabs and embedded menus, the operator can navigate quickly, and within minutes take control to create or manage a working IP Intercom. Create unlimited Groups, Partylines and IFBs, drag-and-drop functions directly onto Panel and Beltpack keys in real-time, and manage AoIP sources and destinations as though they are physical ports on a virtualized Intercom matrix.

Telos Infinity Dashboard is much more than a configuration tool for Telos Infinity IP Intercom. Dashboard also manages all hardware and software elements within the system, including software and firmware updates, and monitors network performance and fault logging. All Telos Infinity systems are supplied with a Dashboard Basic license, a single user application suitable for smaller installations with direct online control and restricted feature set.

Infinity Dashboard Advanced

Infinity Dashboard Advanced is an optimised configuration and system management tool with an extended feature set designed for Telos Infinity Intercom systems of all sizes and applications. It unlocks the full potential of the multi award-winning Telos Infinity matrix-free IP Intercom System.

The Advanced Agent can be installed on either single or dual servers (coming soon) and constantly monitors the Telos Infinity Intercom network as well as any other connected AES67 devices, stream sources and destinations. User Clients connect to the Server Host via any HTML5 compatible web browser using a suitable connected device including PCs, Tablets and Mobile devices.

Dashboard Advanced can be used for all system configuration, from initial set up to ‘on the fly’ changes during live operation. However, Dashboard Advanced does not need to run constantly for Infinity to function normally (although it is highly recommended).

Additional features like System Zone and Scene support enables the user to define dedicated system views of specific components and create snapshots (Scenes) for different productions and applications. Tailored access to specific Zones and Scenes as well as offline configuration modes are all protected by centrally managed user rights administration, ensuring that operators at all levels have restricted access to the resources that they need. Zones and Scenes can be edited, cloned and recalled both in ‘Live’ and Offline modes.

Critical for use within the wider Audio over IP ecosystem, Dashboard Advanced adds a tool that enables direct connection of 3rd party AES67 streams (including SAP for Dante and future NMOS modes).

Telos Infinity users have the option to purchase either single or dual server versions of Dashboard Advanced, each including Systems Administrator login licenses. Further logins for additional clients can be purchased. There is no limit to the number of simultaneous users who can be connected to Dashboard Advanced.

Telos Infinity Link is an OPUS codec-based software product launched as a part of the Telos Infinity solution at NAB 2019. The product takes the form of a series of software licenses that can be added to any host Infinity Panel or Beltpack hardware, unlocking 2 (Beltpack only), 4 or 8 embedded codecs which convert WAN-side VoIP to LAN-side LW+ AES67. There is also a 1ru hardware Gateway device supplied with dual AC power and dual gigabit Ethernet connection supporting either 8 or 16 embedded codecs.

The OPUS codec is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet but is also intended for storage and streaming applications. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype’s SILK codec and Xiph.Org’s CELT codec.

The Product

Link for Beltpack: INF-BP-2/Link2 supports two bi-directional codecs running on a standard Infinity wired BP.

Link for Panel: INF-MP/DS-16 and INF-MXP-20/Link4 and Link8 supports four or eight bi-directional codecs running on standard Infinity Panels (Master, Desktop and Expansion).

Link Gateway: INF-Link Gateway-8/16 supports either 8 or 16 bi-directional codecs running on a dedicated 1ru hardware platform. The product features dual AC power and dual gigabit Ethernet.


Each codec send/receive pair can be connected to an associated pair at a remote location. The resultant LW+ AES67 Sources and Destinations appear within the Dashboard Input/Output lists in the same form as an xNode or any other connected AES67 stream. It is a good analogy to think of Infinity Link as a kind of VoIP based xNode with Infinity connections that can be used in the same way as and xNode, as part of a Partyline, Group, IFB, VP or for Peer to Peer communication.

The Infinity Link Advantage

Infinity Link is a competitive and flexible solution that allows the user to turn a standard Infinity Panel or Beltpack into a VoIP utility without compromising it’s use as a communications device. Unlike other solutions, the fact that the resultant streams are presented as LW+ AES67 audio and are made available within Dashboard as utility connections that are not restricted to use by the host device, means that the system has ultimate flexibility when configuring their use.

It maintains the matrix-free advantage of Telos Infinity but adds the ability to extend connectivity beyond the boundaries of AoIP.
