The Powersoft DUECANALI 6404 DSP+D is a versatile 1RU amplifier engineered for both low-impedance (from 2 Ω) and 70V/100V distributed line systems, allowing seamless mixed-impedance configurations. Powersoft’s legendary efficiency minimizes energy consumption and operational costs, while the fully integrated state-of-the-art DSP delivers advanced system management, precise sound shaping, and limiter functions. Combined with ArmoníaPlus software, it ensures IEC 60849 compliance for emergency sound systems.

The amplifier features a universal switch-mode power supply, patented ripple-cancellation output filters, low inrush current design, and detachable AC mains connection. Complete protection includes AC, DC, clip limiter, VHF, thermal, short-circuit, and long-term RMS safeguards, with temperature-controlled front-to-back airflow and historical monitoring via LCD.

Advanced DSP functionality includes dual 24-bit AD/DA converters, per-channel input/output equalizers, 100 ms delay for time alignment, Active DampingControl™, and TruePower™ limiters. Remote control and monitoring are possible through ArmoníaPlus, a dedicated WebApp, or hardware adjustments such as attenuation, high-pass filters, output type selection, and gain. Compact, lightweight, and flexible, the DUECANALI 6404 DSP+D is ideal for professional installations requiring reliable, high-performance amplification across multiple impedance configurations.
