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

MyPowersoft services are available for this product

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 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 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
  • Switchable 35Hz / 70Hz high pass filter per channel
  • Mixed configuration with Lo-Z/Hi-Z systems possible
  • Bridged mode low impedance per channel pair

Alarms and GPI/O

  • NC/NO contacts per channel for alarm notifications
  • Remote ON/OFF switch
  • Remote VCA control per channel

Remote Control & Monitoring

Via Software:

  • Attenuation (from 0 dB to 26 dB)
  • Max output voltage
  • Output and gain reduction metering
  • Diagnostics (temperature, fans, …)

Via Hardware:

  • Attenuation (from 0 dB to 26 dB)
  • High Pass Filter (35 Hz, 70 Hz)
  • LoZ/HiZ/70V/100V output selection
