Rosario celebrated its 300th anniversary with a historic show before more than 200,000 people and sound worthy of the occasion. Behind that unforgettable experience, the precision of Marti Audio and the power of DAS Audio made the difference, combining technology, passion, and technical excellence on a night that was etched into collective memory.
On October 7, 2025, the city of Rosario experienced an epic night: a massive show to celebrate its 300 years of history, featuring the Rosarina Symphony Orchestra and a special performance by Nicki Nicole as guest artist. The free event, organized by the Ministry of Culture of Santa Fe, brought together over 200,000 people in the Parque Nacional a la Bandera, in front of the iconic monument.
The technical setup was monumental. And among the invisible protagonists of that deployment, sound played a key role. The chosen solution? DAS Audio systems, provided by Marti Audio, the company led by renowned technician Ariel Marti, who was in charge of the entire system installation. “It was necessary to guarantee full coverage in a huge venue, with a very high crowd density and no room for error,” he explains. The result was flawless: a massive concert that combined power, emotion, and sonic precision.
A story built with hard work
Behind Marti Audio is a story of perseverance, passion, and craftsmanship. Founded by Ariel Marti, the company was born more than 20 years ago in Rosario and grew alongside technical experience and market demands. “I started from the bottom, loading gear, working as a tech at festivals. Over time we built a structure, and today we have a solid base with presence throughout the country,” says Ariel.
The company specializes in professional sound solutions for large-scale events, from concerts and festivals to institutional setups. “We always aim for quality. We’re interested in doing serious, technical work, with products that deliver and planning that matches each need,” he states. That approach allowed it to establish itself as a benchmark in northern Argentina, with a client portfolio that includes artists, production companies, and official entities.
Marti Audio is not just a supplier: it’s a company that works hand-in-hand with each production. “The key is understanding what the event needs and designing the system based on that. Sound is not just about power: it’s coverage, definition, pressure, and clarity throughout the venue,” he emphasizes. And in that process, the choice of brands also plays a key role.
DAS Audio as a symbol of trust and power
For more than a decade, Marti Audio has relied on the DAS Audio catalog as the main solution for its events. The reason is simple: reliability, coverage, and sound quality. “When working at this scale, there’s no room for mistakes. DAS guarantees us pressure, definition, and stability in any environment,” says Marti.
For the Rosario concert, the challenge was to cover over 800 linear meters with uniformity. The technical solution included a stepped system of distributed delays, with prior measurements and fine-tuning. “It was a very technical installation. We ran many tests, checked angles, delay, and field pressure. Every box had to be perfectly aligned to not lose even a decibel,” he explains.
Designing the sound system for a concert attended by over 200,000 people was a large-scale technical challenge. To ensure uniform coverage and flawless sound pressure, Marti Audio implemented a DAS Audio system composed of 48 LARA TOP, 40 LARA SUB, and 24 SARA units, ensuring power and clarity in the main front. Although the main system was entirely made up of DAS Audio, the delay towers were complemented with products from another brand due to the venue’s size, thus reinforcing the sound distribution throughout the area.
What defines DAS, according to Marti, is its performance under demanding conditions: “You can work confidently because you know it won’t fail. They behave reliably, both in small events and massive shows.” He adds a conviction that summarizes his experience: “For me, DAS is synonymous with trust: you turn it on, and it sounds. And it sounds good.”
A show that left a mark
With Nicki Nicole on stage and an entire city singing along, the concert for Rosario’s 300th anniversary was more than just a show: it was a collective celebration. But behind that emotional impact was a meticulously designed technical setup, aimed at ensuring the best sound experience in every corner of the venue. “We were sounding for a quarter of a million people. The challenge was immense, but the system performed perfectly,” recalls Ariel.
The event was broadcast via streaming and shown on giant screens, with national media coverage. For Marti, it was a unique opportunity to showcase not only the operational capacity of his team but also the power of the technological solutions they represent. “People get emotional with music. We work so that emotion is heard the way it’s supposed to sound,” he summarizes.
The value of support: Tevelam as a strategic partner
The relationship between Marti Audio and Tevelam, official distributor of DAS Audio in Argentina, has been key to building that trust. “Tevelam is not just a supplier. It’s a partner. They’re always present, with advice, technical support, and available stock. That gives you the confidence to tackle any challenge,” highlights Ariel.
Thanks to that support, Marti Audio has been able to expand its operations and keep its systems updated with DAS’s latest releases. The synergy between user, brand, and distributor is part of the model that guarantees results. “Without that triangle, we wouldn’t be able to do the work we do. It’s a team effort,” he concludes.
Where there’s power, there’s trust
The show for Rosario’s 300th anniversary was more than a massive production: it was a trial by fire. And DAS Audio was up to the task. From technical planning to final execution, the brand once again demonstrated why it is chosen by professionals who leave nothing to chance.
Marti sums it up with a phrase that encapsulates his entire career: “You can have the best musicians, the best stage… but if the sound isn’t there, everything falls apart. And we know that with DAS, the sound is always there.”
