Powersoft has put its name to the multi-platform PAcalculate app for Android, iOS, Windows-Phone and Blackberry devices for anyone working in PA, sound reinforcement, sound systems, electroacoustics and wider professional audio.
Developed by Brusi Acoustics – a Spanish company specialising in electroacoustics and providing an independent laboratory for loudspeaker directivity testing – it is marketed by Doctor Pro Audio, a leading web portal. The app provides calculators, utilities and reference information, and currently supports Simplified Chinese, English, French, German, Italian, Portuguese, Russian and Spanish,
Explaining the sponsorship, , Powersoft Brand & Communications Director Francesco Fanicchi says: ‘We have decided to implement our brand on the app, by focusing on a dedicated session regarding the Powersoft limiter thresholds.’
This tool is designed to provide a starting point for a limiter set-up, performing real-life tests to validate and tune the results. To use the tool, users need to select AES power (Nominal Impedance and Safety Level – from Safe to Performance) of speakers and the result returned by the app will enable a maximum voltage (Threshold Vrms, Threshold Vpeak, Clip V) to be set.
Since these limiters follow specific Powersoft criteria, the company has added a description to emphasise that correct limiting requires at least two stages in series. The first is a slow-reaction time to RMS level, designed to behave as thermal protection for the voice coil. The second, with faster time constants, is set to protect the transducer from excessive voltage peaks and therefore from mechanical damage. There is also an optional Clip Limiter (Powersoft X and Ottocanali Series) with a zero-attack time and look-ahead. It is designed to set maximum voltage, which should never be crossed without adding distortion.
‘I hold the Powersoft brand in very high esteem for its constant innovation, both inside and outside of their comfort zone, so it’s great to see the company as a sponsor of PAcalculate and join the ever growing community of users across the different platforms,’ says José Brusi, the developer of the app.
