NDR Hamburg installs 64 channels of AX24 for new
high-end studio

Press release, May 2009

NDR Hamburg has installed 12 DAD AX24 analog/digital audio converters following the successful completion of listening tests as part of the network's Broadcast Sound Studio 1 project.

"This was, without exaggeration, one of the best acoustics-related technical decisions for the NDR I have been involved in during the past few years," comments NDR sound engineer Michael Plötz. "The digital audio world now enjoys incomparably good sound thanks to the use of the AX 24 in the production chain of this studio. The combination of a DAD AX24 and the SSL Duality console places us in a new 'analog/digital world'".

The completely reworked Studio 1 and Regie 1 at NDR Radio's Funkhaus am Rothenbaum is designed primarily for recording the NDR Bigband, one of the best finest bands in Germany. Studio 1 is built around a 72 fader SSL Duality and Sequoia digital audio workstation software. Eight NTP DAD AX24 converters are connected via MADI to the workstation.

 

Set-up details

The AX24 converters are interfaced to the Sequoia workstation via a daisy-chained MADI connection, which is fully delay-compensated and phase-aligned. Phase shift throughout all 64 channels is less than ±0.6 degrees at 10 kHz. Two of the AX24 converters are equipped with AES/EBU digital inputs and outputs to serve as high-end audio to digital and digital to audio conversion for TC M6000 and Lexicon L960 processors. The remaining two AX24 converters are being used for high-quality classical and jazz recording on location.
