At NAB and AES, the Telos Alliance has shown new ATSC 3.0 and next-generation Linear Acoustic products, expanded Telos Infinity IP Intercom lineup, major update to Minnetonka Audio’s AudioTools Server platform and offerings from Jünger Audio.
The Telos Alliance showcased new products in support of ATSC 3.0 and immersive television audio, as well as updates and enhancements to its existing product portfolio.
New additions to the Telos Infinity IP Intercom platform include Dashboard Advanced software, Infinity Link and new base models of the Master Panel and Desktop Station.
For customers with larger Infinity installations or those who wish to unlock the full potential of the Infinity system is the new Dashboard Advanced software. It includes System Zone and Scene support, off-line configuration, user rights administration and support for directly connecting third-party AES67 streams including SAP, and in the future, NMOS nodes.
The INF-MP-16B Intercom Master Panel Base Model and INF-DS-16B Intercom Master Desktop Station Base Model offer the same features as the INF-MP-16 Master Panel and INF-DS-16 Desktop Station hardware, respectively, but without the rear panel auxiliary audio I/O and GPIO connections. These cost-effective base versions are ideal for use when local I/O and serial logic are not required.
The Linear Acoustic LA-5300 offers what's needed to make the transition to ATSC 3.0 as seamless as possible by offering all audio-related functions in a single 1RU package — including support for SMPTE ST 2110-30 and -31 workflows.
Minnetonka Audio AudioTools Server Version 5 was updated for automated file-based processing. It represents a complete architectural redesign, resulting in faster, more responsive processing, support for REST API, and the creation of even more sophisticated workflows.
Several of Jünger Audio’s globally respected audio processing products were on display and available exclusively through the Telos Alliance. Included in the lineup is the AIXpressor, Jünger’s new flagship processor, which brings the power and flexibility of software-based applications to a reliable hardware platform.
