IBC 2017: MDR Erfurt modernizes broadcast infrastructure with Lawo RƎLAY Virtual Radio Mixer systems

German public broadcaster Mitteldeutscher Rundfunk (MDR) has installed new mixing and editing workstations using Lawo RƎLAY Virtual Radio Mixer software in their Erfurt facility in Thuringia, Germany, as part of a modernization project executed by technical service provider MCS GmbH Thüringen.

MDR’s project goal is to provide more user-friendly tools for their radio editors, talent, and producers, enabling them to streamline their workflows by reducing system complexity and adding mixing, recording, editing and routing flexibility.

More than 30 workstations throughout the building are now outfitted with RƎLAY Virtual Radio Mixer workstations. Journalists can easily accomplish tasks such as audio editing, conducting interviews, recording Internet livestreams, or creating content for TV or radio programs using the intuitive, touchscreen-enabled RƎLAY mixing software. In addition to mixing and recording local audio sources, RƎLAY users also have direct access to all audio signals within MDR’s RAVENNA network, allowing distributed resources – such as telephone hybrids, codecs and other audio devices installed in on-air studios or rack rooms – to be used remotely by RƎLAY workstations, simplifying infrastructure and reducing installed costs.

The project also included deploying an AES67 / RAVENNA audio network to distribute audio in-house. At the network’s heart is a Lawo Nova73 router with dual-redundant RAVENNA cards, connected to a Cisco core switch for optimal reliability.

RƎLAY is radio software that enables broadcasters to build “virtual broadcast studios” using today’s inexpensive and quality desktop as well as laptop PCs. The RƎLAY line includes VRX8 8-fader and VRX4 4-fader Virtual Radio Mixer software, VPB Virtual Patch Bay, and VSC Virtual Sound Card software. All are AES67 compliant for use with standard AoIP networks and multi-touch capable for easy, intuitive use on touchscreen PCs and laptops. RƎLAY can mix all types of native PC audio using included ASIO, WDM, WASAPI and MME drivers, as well as AES67 / RAVENNA streams.
