Brazil - Powersoft’s energy-efficient Duecanali amplifier platform is providing the audio backbone for a wide range of performances and community events across Sesc São Paulo’s network, with more than 100 Duecanali 1604 amplifiers now installed throughout Brazil’s most populous state.
The multi-site programme has been steered by designer and consultant Reinaldo Pargas, whose company, AVM Projetos e Consultoria em Tecnologia, has been working with Sesc since 2003 on projects that balance the organisation’s strict technical standards with the real-world needs of touring artists and educators.
Established in 1964, Sesc (Serviço Social do Comércio, Social Service of Commerce) is a private organisation funded by São Paulo’s business sector to improve the quality of life of employees and their families. As of 2025, it maintains 43 centres throughout the state offering workers a variety of courses, exhibitions, concerts, dance shows, lectures and other cultural and educational activities on a daily basis.
Since Sesc São Paulo began working with AVM Projetos, 14 new Sesc centres have opened their doors, including Sesc Belenzinho, renowned for its experimental theatrical programming and expansive swimming pools, and Sesc 24 de Maio, located in the iconic modernist surroundings of the former Mesbla department store.
Like all Duecanali amplifiers, the 100+ units installed in these centres provide high-quality, distortion-free sound with extremely low power consumption and heat dissipation to suit everything from morning children’s workshops to afternoon concerts and evening talks – often within the same venue and even on the same day. The Duecanali 1604 delivers 800W per channel at 4 or 8Ω (1,000W at 2Ω) in a compact footprint, or up to 2,000W per 4Ω in bridge mode, giving designers freedom to drive both low-impedance loudspeakers and 70/100V distributed lines as required by each room.
The DSP+D variant chosen by AVM adds on-board processing and Dante/AES67 audio networking, enabling inputs to be routed directly over IP and tuned in Powersoft’s ArmoníaPlus software without the need for an external DSP.
The Duecanali 1604 DSP+D’s combination of compact size, high efficiency and low distortion has helped AVM and Sesc deliver consistent sound quality across varied room types, while preserving rack space and keeping heat and energy consumption in check – an important consideration for venues that run full, mixed-use schedules seven days a week, explains Reinaldo Pargas.
“Each Sesc project starts with the same two requirements: we follow SESC’s technical guidelines to the letter, and we make sure artists have what they need to deliver the best possible experience for the audience. and give artists what they need for a great audience experience. Powersoft’s Duecanali 1604 DSP+D amplifier platform has been key to helping us to meet these high standards.
“The compact size, high power output and low distortion levels of the amplifiers, in addition to the ease of controlling them digitally using ArmoníaPlus software and the Dante connectivity, have contributed tremendously to the successful implementation of these projects."
