The South Asian games were held at the Indira Gandhi Athletic Stadium in Guwahati recently. Sound.com, a provider of sound reinforcement and turnkey audio solutions, chose Optocore products to help provide the sound for the opening and closing ceremonies of the event.
The primary audio source was fed via AES to all amplifiers, thus delivering astounding audio quality that remained pristine across the turnkey sound system. Explaining the layout, Sound.com managing director, Warren Dsouza, stated: “The audio system was designed in the round, with the stadium divided into six nodes — FOH, North, South, East, West and Monitors in a redundant loop.â€
An analogue signal driven by Dolby/Lake processors acted as the secondary back-up and ARX line drivers served as the third back-up system. The Dolby/Lake processors served two purposes — its primary job was a switcher from AES to Analog in case of a problem with the digital network and its secondary function was to convert AES signals to analogue wherever needed.
At these particular ceremonies all the VIP tribunes and Athletes Oath podiums were picked up off the Optocore devices from the west node and routed (via Optocore YG2 cards) straight to the Yamaha M7CL console that served as the main mixing console, whilst another Yamaha console was used as the back-up desk. The performances themselves were mixed on a Soundcraft VI6 console.
