For more than four hours, over 35,000 spectators enjoyed the numerous performances of this open-air event. The sound reinforcement company Merino Producciones of Mendoza was responsible for the event's technical production. For the main PA, the company used 24 D.A.S. Aero 28 line array systems flown 12 per side form a height of 10m. A down-fill system of four Aero 28s was used to provide coverage for the first six rows.
Delay towers comprised of four Aero 28A were located 50m from the main stage. According to Carlos Merino, the company director: "Sound pressure levels were very even throughout the entire spectator area peaking around 105 dB". Since the company purchased the Aero systems, Merino Producciones has been using the systems in the majority of their larger events, their previous event being with French superstar, Manu Chao.
