The Powersoft DUECANALI 804 DSP+D is a highly flexible, compact 1RU amplifier designed for both low-impedance (from 2 Ω) and 70V/100V distributed line systems, allowing any mixed-impedance configuration. Equipped with Powersoft’s legendary efficiency, it minimizes energy use, operational costs, and carbon footprint. Its fully integrated state-of-the-art DSP, combined with ArmoníaPlus software, provides advanced system management, sound shaping, and limiter functions while supporting IEC 60849 compliance for emergency sound systems.

Featuring a universal switch-mode power supply, patented ripple-cancellation output filters, low inrush current design, and detachable AC mains connection, the amplifier ensures reliable operation. Comprehensive protections include AC, DC, thermal, short-circuit, clip limiting, VHF, and long-term RMS protection, with a temperature-controlled variable-speed fan and LCD-based temperature history monitoring.

Advanced DSP capabilities include dual 24-bit AD/DA converters, per-channel equalizers (PEQ, shelving, IIR, FIR), 100 ms delay for time alignment, Active DampingControl™, and TruePower™ limiters. Remote control and monitoring are available via ArmoníaPlus, WebApp, and hardware controls for attenuation, high-pass filters, output selection, and gain adjustment. With compact size, lightweight design, and flexible configuration options, the DUECANALI 804 DSP+D is ideal for professional installations requiring precise, reliable multi-impedance amplification.
