description
The ability to implement any configuration with ease makes the Duecanali series extremely flexible. Powersoft's efficiency saves valuable energy and keeps both operating costs and carbon footprint to a minimum. The Duecanali 804 DSP+D is designed for operation with Lo-Z (from 2 Ω) and with 70V/100V distributed lines: any mixed impedance output loads can be realized.
A fully integrated DSP provides extensive system management functionality. In addition to sound shaping and limiter functions in a unique Powersoft style, the DSP hardware and ArmoníaPlus software enable compliance with IEC 60849 for the critical requirements of public address systems in emergency situations.
