A Reliable Partner: the Salzbrenner Family
20 years ago, there was a sense of a new era in the pro-audio industry. This was when the first large digital mixing consoles were developed. The first-generation systems posed a major challenge both technically and from the operator's perspective. At that time, one of the renowned German makers of audio equipment Georg Neumann KG, today known primarily as a maker of excellent microphones constructed analogue mixing consoles, some of which already had a digital user interface. However, Neumann intended to abandon their mixing-console and the development department. The highly motivated team of developers began looking for a solution which would enable them to continue working on innovative console designs. Finally, they met Friedrich Salzbrenner who together with his three sons Wolfgang, Thomas, and Stephan ran a well respected business offering comprehensive systems solutions. They seized the opportunity and jointly founded STAGETEC based in Berlin.
The Salzbrenner family acted as a partner and distributor and with good contacts in the industry, especially in the theatre market, opened many doors. When, after only four months, STAGETEC introduced the first prototype of the NEXUS audio router, it created a minor sensation. Shortly after, the very first NEXUS installation in the Berlin Musical Instrument Museum recording studio went into operation. It consisted of a small fibre-optic audio network including two NEXUS Base Devices and is still in use today!
Novel Approach
The audio router was not the sole product for long. Digital technology made it possible to make fundamental changes to system architecture since signal processing and system control could be provided by totally different elements. And so, the STAGETEC development team came up with the revolutionary idea of using the audio network with its inputs, outputs and complex routing abilities as the basis for a digital mixing console. Development of digital signal processing and an ergonomic and aesthetically pleasing user interface were the final steps on the road to achieving the goal: CANTUS was born! At the 1994 Tonmeistertagung, it received an enthusiastic welcome from the audience thanks to its intelligent design. The CANTUS consolidated STAGETEC's reputation as an innovator in professional digital audio technology
High Level of Acceptance
A few years later, the NEXUS and CANTUS systems had become accepted internationally with installations at the Kourou Space Station, the United Nations, the Kremlin, a number of Hollywood studios and countless theatres. Broadcasting is another important field. For example, more than 30 CANTUS consoles have been shipped to Italy, most of them going to the state broadcaster, RAI.
Meanwhile, the company's rented premises had become too small, so a new headquarters building was commissioned. In autumn 1999, the entire company moved to the new site in the heart of Berlin. The new company headquarters includes manufacturing production lines, well-equipped offices and workshops, various QC facilities and even a recording studio.
Great Product Family
With the transition from analogue to digital, the size of professional audio technology played an increasingly important role. Ever since the advent of multichannel audio not only the capacity of the mixing consoles' but also the audio networks' capacities have grown steadily. Several thousand inputs and outputs are no longer a rarity, so in 2000, STAGETEC introduced the NEXUS STAR, a routing node for large audio networks. The NEXUS STAR made huge waves in the audio-network market thanks to its sheer size combined with legendary reliability. This also made it a door-opener to the US market.
The equation of audio router plus DSP plus user interface equal a very efficient audio console remains true today. All CANTUS successors from the CINETRA (1997) to the AURUS (2002), the AURATUS (2006), the CRESCENDO (2009) and the ON AIR 24 (2010) are based on this design. Today, these systems are often part of a flexible mixer pool on a large network.

In the meantime, the developers worked continuously on innovative detail improvements: From the then-standard 18-bit converter they developed the most powerful audio converter in the world: the patented TrueMatch 32-bit converter (since 1996). New functions were added for example, the user-programmable Logic Control (2004) for even tighter systems integration; the SDI embedder/de-embedder featuring sample-rate converters for processing audio from asynchronous video streams (2004); and the Dolby-E encoder and Decoder to ensure seamless Dolby-E multichannel-audio workflows (2008/09). At the same time, software and hardware have evolved continuously. Latest developments include the implementation of Loudness Metering (2011) on each NEXUS and the close cooperation with Audinate which resulted in the integration of the Dante system (2012).
Awards Galore
With analogue mixing console technology users, especially German public service broadcasters, place considerable emphasis on the highest technical quality. On the other hand, the appearance of the majority of mixing solutions used to suggest that they had come straight out of an engineering research lab. STAGETEC deliberately departed from this well trodden path, right from the beginning. The user interface of the first CANTUS console was designed by tonmeister and STAGETEC co-founder Harald Klaus in collaboration with an i
