The new full-sphere surround sound room at SPACE, Pesaro


SLOVENIA


Renkus-Heinz brings Tchaikovsky to Tivoli


The PN series: born to ballet


By Jon Chapple


AUDIO FOR an Imperial Russian Ballet performance of Swan Lake, attended by national and international dignitaries, at Tivoli Hall, Tivoli Park, Ljubljana, was provided by Akustika Pirman,


who supplied a system based on Renkus-Heinz PN-series line- array loudspeakers.


“The Hala Tivoli actually has pretty good acoustics for a sporting arena, and it’s possible to get a reasonably good sound in the room,” comments systems engineer Metod Komatar. “The


biggest challenge is the height of the left and right seating areas, and how to cover it consistently using a relatively small number of loudspeakers.”


The main system, designed by Komatar and director Joze Pirman, comprised four flown arrays – two left and two right – each with six PN102 line-array cabinets, with six DRS18-2B subwoofers covering low- frequency reinforcement. Four TRX151 full range cabinets provided front fill for the first few rows, while two more TRX151 boxes onstage served as side fills for the artists. “The PN102 line-arrays deliver a wide dispersion that enabled us to consistently cover a large area with a small number of speakers,” concludes Komatar. The Renkus- Heinz system proved itself once again, with a very natural sound and plenty of headroom – critical for classical music.”  www.akustika-pirman.si www.renkus-heinz.com


ITALY Found in SPACE By Mike Clark


BASED ON an idea, project and design by Davide Monacchi and Eugenio Giordani, the first full-sphere surround sound room in Italy was recently inaugurated in Rossini Conservatory’s SPACE (Soundscape


Projection Ambisonic Control Engine) research and music production centre in Pesaro. The system, which features a Neumann 21.1 system (21 Neumann KH 120 self-powered studio monitors and a Neumann KH 310 subwoofer), will be used for research work in acoustics, audio perception and acoustic ecology; experiments and development of software applications for 3D sound


spatialisation; and electro- acoustic and eco-acoustic composition and production of music for museums and performances.


The project intends to


collaborate for specific research and production projects with other facilities in Italy and similar centres in Europe and North America.


Software is run on a


Mac Pro 8-core 3.0GHz Intel Xeon E5 (with 32Gb RAM and 1TB HD) and an iMac 3.4GHz. In addition to equipment for electro-acoustic generation, the set-up at the team’s disposal includes an RME Madiface XT, an RME HDSPE audio interface and a DO/TEC Andiamo 32-channel AD/DA converter.  www.rossinispace.org
