Description

Axia Radius 8 Fader Digital Broadcast Mixer

Radius is an all-in-one console system designed for small standalone or networked studios, where no more than eight faders are needed. Like all Axia® consoles, it’s easy to deploy: each Radius control surface is powered by a burly QOR.16 integrated console engine with DSP-powered mixing engine, analog and digital audio I/O, custom Ethernet switch and GPIO ports. The Radius surface connects to the QOR.16 engine with a single CANBus cable.

Radius includes 4 stereo Program buses — 3 dedicated Program, Audition and Utility mixing outputs; the fourth a stereo Utility bus for recording phone callers or other off-air bits. The fourth bus may also be used as an additional Program bus. Automatic mix-minus is provided on each fader, plus talkback functions, one-button off-air Record Mode, Show Profile instant recall of up to 4 pre-defined console “snapshots”, LED bar-graph program meters switchable between VU and PPM meter styles, high- resolution OLED option displays on each fader, and Studio and Control Room monitor controls. Radius can be placed on top of desk surfaces, mounted drop-in style, or rack-mounted using included hardware.

Axia Audio  Axia logo - Pro FM broadcast

Way back in 2003, Axia Audio, the studio audio division of Telos Alliance, invented Audio over IP for Broadcast. We did what no one had ever done before create professional radio gear that networks using standard Ethernet for use in digital audio routing, mixing, and distribution systems for Broadcast and other Pro Audio applications. The foundational technology in all Axia products is Livewire plus AES67—we call it Livewire+—an AoIP protocol that enables high-reliability, low-delay uncompressed digital audio over Ethernet, including audio, logic, control, and program-associated data (PAD). Devices connect together using standard Ethernet cables; audio and control routing is accomplished with off-the-shelf Ethernet switches. Axia Livewire+ has built-in compliance with the AES67 standard. That's because Axia and Telos Alliance are committed proponents of AoIP interoperability—first as charter, supporting members of the X192 Working Group that defined AES67, and now as founding members of the Media Networking Alliance, a group of prominent equipment manufacturers formed to actively promote the adoption and implementation of the AES67 standard. Today, Axia mixing consoles, digital audio routers, broadcast intercom systems, and routing control software—along with other Telos brands and 85+ partners—are powering broadcast studios around the globe, with more than 8,000 mixing consoles and 100,000 networked audio devices
