The Duecanali 1604 DSP+D from Powersoft is a powerful 1RU installation amplifier designed for high-performance commercial and professional audio systems. It features a universal switch-mode power supply with Power Factor Correction, tolerant up to 400VAC, along with a patented ripple-cancellation output filter and low inrush limiting to simplify installation. Despite its high output capability, it remains lightweight at just 7 kg and includes efficient front-to-back cooling with temperature-controlled variable-speed fans and LCD thermal monitoring.

Engineered for reliability, it incorporates comprehensive protections including AC, clip, DC, VHF, short-circuit, long-term RMS limiting, and thermal safeguards. The amplifier supports both low-impedance and 70V/100V high-impedance systems, with selectable 35Hz/70Hz high-pass filters, mixed Lo-Z/Hi-Z configurations, and bridged operation. Built on a TI C6000 DSP platform with 24-bit/48kHz converters, it offers advanced equalization (IIR and FIR), up to 100 ms delay, Active DampingControl™, and precise Peak, RMS voltage, RMS current, and TruePower™ limiting. Remote control and monitoring are available via ArmoníaPlus software and a dedicated WebApp, while hardware controls allow gain, attenuation, and output mode adjustments, making it ideal for demanding distributed and installed sound applications.
