NBTV installs Jünger Audio to deliver superior audio quality

Berlin, Germany – NBTV, a Chinese broadcaster based in Ningbo in the Zhejiang province, has chosen technology from German dynamics specialist Jünger Audio to ensure delivery of superior audio quality to its audiences.

The company has installed five Jünger Audio D*AP LM4 four-channel Digital Audio Processors to tackle loudness control across all of its television channels. The D*AP LM4 units incorporate Version II of Jünger Audio's LEVEL MAGIC algorithm and feature on-board AES/EBU digital I/O, along with optional 3G/HD/SD-SDI I/O or analogue I/O.

This important sale was negotiated by Jian Gao, head of Jünger Audio's China office, in conjunction with the company's local sales partner Rotec China, which specialises in providing solutions to the broadcast market. Based in Shanghai, Rotec China also supplies equipment from manufacturers such as Dolby, Sony, Canon and FOR-A.

NBTV tested a number of different manufacturer's loudness solutions before choosing the Jünger Audio D*AP LM4. Its decision was based on the unit's overall sound quality and its ability to control loudness across different programmes and different channels.

Loudness control in China is now receiving serious attention from both the government and from the major broadcasters, all of which are state owned and have their investment in technology secured every year. As in other parts of the world, loudness control is being driven by complaints from viewers who are often irritated by inconsistencies in level between different channels and between programmes and commercials.

Tim Zhong, Sales Engineer for Rotec China who was in charge of the NBTV project, said, “China's regulatory body SARFT is set to issue its own standard on audio loudness and we believe that this will be specify -24LKFS as the average loudness level. This is similar to the standard that has already been adopted in Europe and the USA and for this reason many Chinese broadcasters, including NBTV, are implementing the ITU1770 standard.”
