Powersoft cofounder to speak at AES convention in Milan

Claudio Lastrucci, cofounder of Powersoft, is set to present a case study entitled ‘Mains to Acoustic Efficiency’ at the Audio Engineering Society (AES) International Convention, Europe’s premier professional audio technology and

networking event, which is taking place in Milan from 23 – 26 May. The AES event, which alternates between a US and European location each year is in its 144th edition.

With its ‘Power of Sound’ theme inspired by Italy’s rich heritage of innovation, Lastrucci will be sharing key insights with all attendees during a one-hour long session which is set to be a highlight of this year’s AES convention. The Powersoft co-founder will be exploring powering subwoofer cabinets at high levels, taking to Arena 1 on Friday 25 May at 12.30pm as part of the Audio Applications Forum Sessions (AAF02).

Lastrucci’s case study will demonstrate how the power requirements to feed a subwoofer are defined. Standardised and program audio signals will be applied and results directly measured on real devices. Measurements of true power input, true power output, and overall efficiency in the amplification chain will be addressed including different amplification topologies. This will reveal surprisingly high overall mains input to acoustic output chain efficiency in the specific, usable, passband of the speaker.

Claudio Lastrucci cofounded Powersoft S.p.A in 1995 in Florence (Italy), and acts as research and development director for the professional amplifier manufacturer. In this role, he works across power electronic, audio amplification signal processing, applied mechanics, acoustic and transducer design. With an Italian Laurea in electronic engineering from the Faculty of Engineering at Florence University, he is widely recognised as a thought leader and innovator in the professional audio world.

Lastrucci commented: “As an Italian audio manufacturer it is wonderful to welcome the AES Convention to Milan for its European outing this year. Our home country is known globally for its technology and manufacturing prowess, rooted in a culture of invention and innovation which is evident way back in history. The AES convention is a key date for us every year, I look forward to sharing our knowledge and expertise with our peers at the event, as well as meeting with industry colleagues old and new to share ideas and insights on the latest pro-audio industry developments.”

Powersoft is behind some major industry breakthroughs in professional amplification. The Italian manufacturer was the first to introduce technologies such as pulse width modulation (PWM) and power factor correction (PFC). Powersoft was also the first company to develop amplifier modules for active speakers, which led to the patented differential pressure control (DPC). The company is also recognised by the industry for the revolutionary approach it took with transducer technology for subwoofers with M-Force, a moving magnet linear motor.
