Jünger Audio flexAIserver Overview
The Jünger flexAIserver provides maximum processing power and flexibility where high program counts and comprehensive processing are required. The flexAIserver can be used with traditional multichannel audio interfaces or with AoIP streams such as Telos Alliance Livewire+ or AES67 in support of SMPTE ST 2110-30 or -31. A new processing architecture, flexAI, makes deploying legendary Jünger Audio processing on the flexAIserver simple and straightforward. Easily tailored to match your exact needs, flexAIserver is a true processing powerhouse. When using Junger Audio’s new interface format, tieLight, flexAIserver can transport up to 1024 channels of virtually latency-free audio to an additional processing unit such as AIXpressor
Jünger Audio flexAIserver In Depth
Powered by an x86 based commercial server, flexAIserver is Jünger Audio’s most powerful audio processing solution. Featuring the flexAI software platform, its flexibility and advanced audio processing architecture offers almost unlimited possibilities. License-based expansion makes future upgrades simple as technology evolves.
The flexAIserver comes in a compact 19” housing, packed with a high-performance processing system and built-in Audio-over-IP (AoIP) interfaces supporting Telos Alliance Livewire+, AES67, and SMPTE ST2110-30 and -31 with ST2022-7 stream redundancy.
To guarantee maximum compatibility, flexAIserver can be equipped with an optional tieLight PCIe card which provides either MADI or Jünger Audio’s new tieLight connections. For demanding media connections, network cards with two 10-Gigabit Ethernet ports instead of the standard array of four 1-Gigabit Ethernet ports can be installed.
tieLight - Any Channel, Anywhere
flexAIserver and AIXpressor can be linked to form a processing array, providing distributed processing and load balancing for high-program count applications. To exchange audio and data between devices, we developed tieLight, a multichannel, lowlatency point-to-point connection for cascading several devices. One optical tieLight interface is capable of transporting up to 1024 audio channels in each direction. Since the flexAI system ensures that all necessary audio is distributed to where it is required, the system sees the entire array as a single device, making cascading units and processing simple and easy.
Following Jünger Audio’s tradition of comprehensive remote control and automation, all functionality is operated from a newly-designed web interface.
flexAI runs on a highly customized Linux operating system, flexAI core, to guarantee broadcast-grade stability, easy administration, and the best system security possible. Administrators are empowered to maintain system functions, and critical security patches will be provided and integrated into standard administration procedures and schedules. Though flexAIserver is a powerful audio processing tool, it will also feel familiar from an IT standpoint, so supporting it on your network is simple for both the audio and IT departments.
Eco and Budget Friendly
Considering its processing power and capabilities, flexAIserver’s high-efficiency redundant power supplies use very little power and help reduce the carbon footprint of your facility.
