Yamaha CL system mixes complex KOHAR concerts
21 December 2012
USA - Armenian symphony orchestra and choir KOHAR has enjoyed remarkable success since it was formed 25 years ago. Performing across the world, the ensemble recently returned from a series of shows in South America, at which three Yamaha CL5 digital consoles were utilised.
With over 140 musicians, a choir, 12 solo singers and a dance troupe of 11 to accommodate, the shows required a flexible audio system with a large channel capacity and reliable connectivity, but which was easy to implement. Hamburg-based Pinguin Audio Production asked Arthur Koll from Yamaha Music Europe GmbH to act as the tour's Live and Broadcast Audio Consultant, supervising the system design and deployment for the elaborate show.
The system comprised one CL5 at the monitor position and two more at front of house - one doing submixes which were fed via Dante to the other two consoles. Thanks to their small size, six Rio3224-D i/o units were placed directly within the rhythm, brass, woodwind and choir sections - providing the shortest microphone cable runs possible. Connected in redundant mode to a set of four Teqsas Cyberteq units, the system was failsafe.
"The flexibility of the CL Series allowed me to quickly set up complex systems, which could be easily changed for each venue. It allowed myself and others in the audio production teams to get on with our 'real' job of making the show sound as good as possible," says Arthur.
Playing nine shows in 2000-3000 seat venues in Brazil, Argentina and Uruguay, much of the audio infrastructure was provided by Sao Paulo-based rental company Gabisom. Just 14 CAT5e cables were required on stage between the Rio units, the CL5 on monitors and the Cyberteq units.
"The analogue alternative would have required three huge 80 channel analogue consoles, a large splitter rack with 160 channels split to four outputs each and hundreds of cables," says Arthur. "The Gabisom team were very pleased with the simplicity of the setup."
Also very happy was Ralph Kessler, Head of Audio at Pinguin. "Dante Controller, along with the control built into the CL consoles, allowed us to have access to the audio patch at any point at any time. In parallel we could monitor the complete Sennheiser wireless system on stage via the fibre optical backbone from the FOH position using IP based monitoring software without adding extra cables," he says.
The final part of the system was three Apple laptops running Dante Virtual Soundcard and Steinberg Nuendo 5.5, using Nuendo's System Link feature to record the performances for virtual soundchecking. It allowed Arthur to record 143 microphone feeds and 12 stereo submixes without a hardware-based soundcard.
"As well as saving a huge amount of time setting up each show, the use of Dante Virtual Soundcard and Nuendo was of particular benefit to the technicians broadcasting the three Buenos Aires concerts for television and live webcasts," says the company.
"Live broadcast sound is difficult because normally the first time you see the signal 'for real' is the time that it's going to air. Using the virtual soundcheck multitracks, the broadcast engineers had a very accurate idea of exactly what was going to arrive when the show began," says Arthur.
