The ability to implement any configuration with ease makes the Duecanali series extremely flexible. Powersoft’s legendary efficiency saves valuable energy, keeping both operational cost and carbon footprint at a minimum.

The Duecanali 804 DSP+ is designed to work with Lo-Z (from 2Ω) and with 70V/100V distributed lines: any mixed impedance output loads can be realized.

A fully integrated state-of-the-art DSP yields 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 crucial requirements of sound systems for emergency purposes.

DSP+ versions extend signal routing capabilities with the integration of AES67 digital audio networking architecture.

Powersoft Duecanali 804 DSP+ Features

  • Power Supply
    • Powersoft legendary universal switch-mode power supply up to 400VAC tolerant with Power Factor Correction
    • Patented output filter with ripple cancellation network
    • Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
    • Detachable AC mains cable with IEC C19/22.2 (16A for EU, 20 A for USA) socket
  • Protections
    • Ac protection: shut down power supply when AC mains voltage is outside the operating range
    • Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
    • DC protection: protects against infrasonic signal at the outputs
    • VHF protections: protects the loudspeakers against non-audible, strong, non-musical high-frequency signals
    • Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset
    • Long term limiter: protects the loudspeaker against steady long term RMS (non-audio) signals, by reducing maximum output
    • Thermal protection: output stages operating temperature up to 80 °C (176 °F)
    • Temperature controlled continuous variable speed fan, front to back airflow
    • Temperature forecast with LCD traced historical behavior
  • General
    • Fixed frequency switchmode output stage for high grade sound accuracy
