Overview

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+D is designed to work with Lo-Z (from 2 Ω ) 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 unique Powersoft style, the DSP hardware and ArmoníaPlus software enable compliance with IEC 60849 for the crucial requirements of sound systems for emergency purposes.

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

Fully protected circuit design with:
  • Ac protection: shut down power supply when AC mains voltage is outside 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 switch-mode output stage for high grade sound accuracy
  • Compact size - all models only 1 RU for reduced rack cost and space
  • Lightweight - for easier racking and shipping: 7 kg (15.4 lbs)
  • Standard Phoenix connectors: analog audio outputs, aux supply, alarms and GPIO
  • Remotely switchable double input (main and aux) per channel

Loudspeaker system configuration

  • Direct drive either low impedance loads or 70V / 100V Hi-Z distributed lines
