The main stage audio infrastructure was composed of 56 systems STS line SLA V7 + (16 per side in PA, 11 per side as reinforcement and 2 for front fill) and the amplifier Powersoft DigiMod 3004PFC4, processing DSP4 card module. In addition it had 28 Concerto Infrasub units working with seven K10 DSP amplifiers. And the harmony software was used to control the system.

On the occasion of the celebration of the bicentennial of Argentina, the province of Tucumán Hippodrome is has with-poured on the stage where he acted, for eight days, a large number of artists. For her were a scene of great dimensions that was sonorizado using systems mounted STS and the amplification of Powersoft.

Equaphondistributor of Powersoft in Argentina and Uruguay and maker of STS, through the engineer Eduardo Sacerdoti, provided technical support to the company's income Home Pro to sound to the main stage. A sound system that was integrated by systems 56 STS line SLA V7 + (16 per side in PA, 11 per side as reinforcement and 2 for front fill) and the amplifier Powersoft DigiMod 3004PFC4, processing DSP4 card module. In addition were 28 STS Concerto Infrasub units working with seven Powersoft K10 DSP amplifiers. The harmony software is used to control this system.

Due to the magnitude of the event, the production raised an area of approximate audience of 180 × 80 meters, i.e. more than 14,000 square meters. This proposed the need for reinforcements.

The prediction of the system took place in Ease Focus and angles were adjusted to achieve optimal coverage. Reinforcement towers were located 65 metres from the PA and a length of 100 metres was also raised. In this way with 11 cases on hand could be the necessary coverage, especially for middle and high frequencies. After that lined up the system and subwoofers went on to set up reinforcements, also using the harmony software.
