TV Nova, the biggest commercial television station in the Czech Republic, has replaced its former audio processors with Jünger Audio’s Level Magic™ technology to help prevent surprise level changes when switching from one audio source to another.

The Prague-based station, which began broadcasting in 1994, is now owned by Central European Media Enterprises (CME). It reaches 98% of the country’s population of 10.2 million and provides a programme mix that includes its own fiction and non-fiction productions, foreign acquisitions, entertainment shows and news.

In 2008, TV Nova began broadcasting in High Definition via its Nova HD and Nova Sport HD channels. It also has a strong internet presence.

The decision to switch its audio processing to Jünger Audio’s Level Magic technology has already proved to be the right one, says Josef Uher, head of service and support for TV Nova.

“We have invested in 10 Level Magic frame-based C8086 units and these have been installed across four of our broadcasting channels,” Uher explains. “Level Magic provides a safe algorithm for controlling audio level and is functionally very reliable. Our engineers are very pleased with the performance of these units and with their overall sound quality.”

TV Nova’s Level Magic system was supplied and installed by Jünger Audio’s Czech distributor Mediatronik.

Lubomir Novacek, director of Mediatronik, says: “Broadcasters in the Czech Republic are well aware of the problems caused by surprise level changes when switching from one audio source to another. Peak level and dynamic range not only vary between programmes but can even vary during the same programme depending on how many different audio sources are being used. Balancing these so that viewers don’t have to rely on their remote controls to constantly adjust the volume is a major problem – and one that requires an effective and economic solution.

“Jünger Audio’s Level Magic technology is providing TV Nova with a viable solution to this problem. The automated nature of the system makes it very easy for broadcasters to operate. All they have to do is install it into the transmission chain and set the correct parameters– after that there is very little to do because the system effectively looks after itself.”

Jünger Audio’s LEVEL MAGIC is a sophisticated adaptive level control algorithm that is designed to adjust the level from any source at any time, with no pumping, breathing or distortion. It is based on a simultaneous combination of an AGC, a Transient Processor for fast changes and a “look ahead” Peak Limiter for continuous unattended control of any programme material, regardless of its original source.

Capable of using any kind of I/O (Analog and Digital) sources, as well as SDI, HD/SDI, Dolby 5.1 and all its related metadata, LEVEL MAGIC is available in a variety of configurations to suit different applications.
