BASEL,
Switzerland – Audioconsulting AG recently deployed a Studer Vista X digital
console from HARMAN Professional Solutions at Raiffeisen Bank’s Dialogue Plus
event that brought together 10,000 Raiffeisen employees and board members in a
32,000-square-meter hall. The Studer Vista X enabled engineers to efficiently deliver
clear audio in several different languages to multiple zones throughout the
event space. Raiffeisen Bank was able to effectively communicate with a diverse
group of attendees, making the large-scale corporate event a success.
Held at the
Messe Basel in Switzerland, Raiffeisen Bank’s Dialogue Plus featured a total of
28 meeting zones, each hosting up to 400 attendees, where organizers held
workshops on many different topics. Martin Reich of Audioconsulting AG planned
a distributed audio network, using the Studer Vista X as the central routing
and mixing system. For this, Reich deployed a comprehensive communications
solution built on Riedel Communications’ MediorNet real-time media network,
RockNet audio network and Artist digital matrix intercom system.
Reich took
advantage of Studer’s VistaMix function, which enabled him to automatically create
clean live mixes for each zone, resulting in significant manpower savings and
broadcast-grade performance.
In turn,
Raiffeisen Bank was able to effectively communicate with its diverse group of
attendees, making the large-scale corporate event a success.
While each
zone at the event held its own workshops, occasional news broadcasts were fed
to each zone’s discrete screens and PA systems. These broadcasts were produced
live in a designated newsroom and featured speeches from the Raiffeisen management
board as well as conversations with participants and guests. Each attendee used
infrared earphones for translation of the broadcasts into his/her preferred
language.
With 66
total microphones in use and 29 discrete zones to manage, the risk of background
noise and microphone spill was considerable. A common problem in such scenarios
is the audio engineer needing to manually adjust all the faders of the console in
real time, leaving the microphones of talking participants open, while trying
to close the microphones of silent participants to reduce spill and background
noise. If the engineer does not react quickly enough, he or she can miss the
audible fade-ins of people who begin speaking unexpectedly, while the changes
in fader positions can lead to unwelcomed changes of the total ambience and noise
level in the mix.
The Studer
VistaMix technology is capable of mimicking the action of the engineer, but at
a much greater speed. It increases gain for “talking” microphones and reduces
gain for all others, keeping the amount of total gain constant, thus creating a
clean live mix.
“The most
impressive part was having 29 VistaMix processes working simultaneously—28 for
the zones and another one for the newsroom,” Reich said. “This greatly
simplified the daunting task of managing the audio in so many discrete areas,
where the potential for distracting background noise was considerable.”
Fifty-six
wireless microphones from the 28 zones and 10 microphones from the newsroom
were the main sources feeding the Vista X digital console. As the zones were
distributed throughout the hall, their microphone signals were fed through a
Riedel MediorNet signal transport network to cover the long distances to the
newsroom, where the Studer Vista X was located. RF microphone feeds were fed
over a Dante™ network and were tunneled over IP trunks of the MediorNet system.
In addition, 30 media servers fed the stages, newsroom and translation cabins.
The PA and
infrared system feeds from the Vista X also used a MediorNet signal transport
system to reach the stages and were extracted with Riedel RockNet devices. All
communications were done through Riedel ARTIST digital matrix intercoms, which
were also interfacing with the Vista X.
The system
featured redundant Studer Infinity Core processors with two Studer D23m frames,
feeding MediorNet with redundant Studer A-Link streams, providing a capacity of
384 channels. All I/O signals were using the A-Link interface, with the
exception of the RF microphones that were connected through two Dante cards.
Approximately
120 input channels were used with the Vista X, with 30 groups for the stages’
infrared feeds, 30 aux groups for the stages’ PA feeds, one master group for
the newsroom program and eight aux groups for ear and monitor feeds.
