Located in the FÜRST development area on Berlin's Kurfürstendamm, the facility houses 104.6 RTL, 105’5 Spreeradio, 93.6 Jam FM and RTL Germany’s Hitradio. It is also home to the Bertelsmann Audio Alliance, RTL Audio Marketing, Digital Media Hub and RTL Radio Deutschland. Broadcast systems integrator audioone, also based in Berlin, supplied, configured and installed the DHD Audio equipment.

"RTL decided to consolidate all its audio units under one roof," comments Heiko Liebig, Project Manager of audioone. "Interlinking all the production facilities will also promote innovation, simplify processes and increase quality. The entire working environment is designed to encourage creativity. RTL set the course for mobile working to become a normal part of the production process long before coronavirus concerns made this a necessity. DHD Audio's RX2 and TX sound mixers were the preferred choice for each of the radio production studios, all networked to primary and secondary XD2 cores with failsafe fast switchover. The result is a versatile, highly reliable and easy to control system which allows efficient audio content creation at the highest quality."

"We are very pleased to have been selected as a technology partner in this very high profile project," says Christoph Gottert DHD Audio. "RX2-based mixers form an ideal basis for the networked style of operation now favoured by many broadcasters and post production houses. They also contribute to the relaxed and informal atmosphere favoured by radio content producers in Germany and around the world."

The DHD Audio RX2 sound mixer is based on control surface modules which can be combined and configured to match a wide range of radio and TV production environments. The design also scales easily from small mixing panels with 6 or 12 faders to large consoles with up to 60 faders. Each module has a dedicated touch display which gives operators the information they need to work quickly and confidently.

DHD's Series 52 TX is an ultra-compact tabletop touch-screen mixer optimised for daily operation in news desks, edit suites and satellite link vehicles. Measuring just 256 mm wide x 58 mm high and 272 mm front-to-back, it has a 10.1 inch IPS LCD monitor with capacitive touch-screen faders plus six hardware pushbuttons and two assignable potentiometers. Other features include an XLR microphone input, an XLR/6.3 mm jack combination headphone output, an integrated talkback microphone and a loudspeaker. The TX connects to the network via a single RJ45 port.

The XC2 Core provides the processing needed to drive DHD control consoles of up to 44 faders capacity. Supporting up to 3,716 x 3,076 digital audio switch points, it occupies half the width of a 19 inch 1U rack slot. Standard network cables and structured cabling can be used for the interconnection of DHD modules, dramatically reduce installation costs. Optional AoIP modules allow up to 128 channels of uncompressed bidirectional audio to interface with other AoIP-compatible devices via a standard Ethernet network. Monitoring, talkback and connection of remote facilities can all be performed via the network.
