Product Description

The xNode lightweight, half-rack, high-performance IP-Audio interface from Telos Alliance is loaded with advanced features and capabilities. One-button configuration takes a new xNode from out-of-the-box to on-the-air in under one minute. They’re fanless, which means they’re noiseless too. Versatile mounting options let you deploy two xNodes in just 1RU of rack space, or on ceilings, walls, and under counters with an available wall-mount kit. xNodes have studio-grade audio performance specs. Redundant power options (using AC mains and Power-over-Ethernet) and dual-redundant network interfaces are included, both with automatic switching. And xNodes are fully AES67-compliant, so they work with all AES67 audio gear—now, and in the future. In fact, they are the first and only AoIP I/O devices that are Livewire+™, RAVENNA, and AES67 compliant. Every xNode not only supports RAVENNA audio stream interoperability, but also enables advertising/discovery of those streams natively, above and beyond AES67.

xNodes are available in Analog, AES/EBU, Microphone-level, Mixed-Signal, and GPIO versions to handle virtually any signal encountered in today’s broadcast studio.
