The Duecanali 804 DSP+D from Powersoft is a compact yet powerful two-channel amplifier designed for professional installed sound applications. It features Powersoft’s legendary 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 eliminate the need for external power sequencers. Housed in a lightweight 1RU chassis (7 kg), it offers detachable IEC power connectivity and efficient front-to-back cooling with temperature-controlled variable-speed fans and LCD-based thermal monitoring.

The amplifier provides comprehensive protection including AC, clip, DC, VHF, short-circuit, long-term RMS limiting, and thermal safeguards. It supports both low-impedance and 70V/100V high-impedance systems, with selectable high-pass filters, bridged operation, and mixed Lo-Z/Hi-Z configurations. Built on a TI C6000 DSP platform with 24-bit/48kHz converters, it offers advanced EQ (IIR and FIR), up to 100 ms delay, Active DampingControl™, and precise Peak, RMS voltage, RMS current, and TruePower™ limiting. Remote monitoring and control are available via ArmoníaPlus software and a dedicated WebApp, while hardware controls include gain adjustment, attenuation, and output mode selection, making it ideal for commercial, hospitality, and large distributed audio systems.
