Fully protected circuit design

Providing access to all yet easily set up, the Duecanali Series is versatile in use. Powersoft’s legendary efficiency saves valuable energy, keeping both operational cost and ‘carbon footprint’ at a minimum.

The Duecanali 1604 is designed to work with Lo-Z (from 2 ohms) and with 70V/100V distributed lines: any mixed impedance output loads can be realized. »

Power supply

  • 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 reducing maximum output
  • Thermal protection: output stages operating temperature up to 80 °C (176 °F)
  • Temperature controlled continous variable speed fan, front to back airflow
  • Temperature forecast with LCD traced historical behaviour

General

  • Fixed frequency switchmode output stage for high grade sound accuracy
  • Compact size – all models only 1 RU for reduced rack cost and space
  • Light weight – 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
  • Gain (from 26 dB to 35 dB)
