The ability to implement any configuration with ease makes the Duecanali series extremely flexible. Powersoft's legendary efficiency saves valuable energy and keeps both running costs and "environmental footprint" to a minimum.

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

power supply

  • Legendary universal switching power supply from Powersoft with a tolerance of up to 400VAC and power factor correction
  • Patented output filter with Ripple Cancellation Network
  • Low inrush limiting reduces AC inrush current and eliminates the need for expensive power sequencers
  • Detachable AC power cord with IEC C19/22.2 socket (16A for EU, 20A for US)

protective functions

  • Fully protected circuit design with:
  • Ac Protection: Shuts off the power supply when the AC grid voltage is out of the operating range
  • Clip Limiter: Prevents heavily clipped waveforms from reaching the speakers while maintaining full peak power
  • DC protection: protects against infrasonic signals at the outputs
  • VHF Protection: protects the speakers from inaudible, strong, non-musical high frequency signals
  • Short circuit protection: protects the amplifier from short circuits or other stressful events for the output circuits with automatic protection reset
  • Long term limiter: protects the speaker from steady long term RMS signals (non-audio signals) by reducing the maximum output power
  • Thermal protection: Amplifier operating temperature up to 80 °C (176 °F)
  • Temperature-controlled, infinitely variable fan, front-to-back airflow
  • Temperature prediction with LCD tracked historical behavior


  • Fixed-frequency switching output stage for high-quality sound accuracy
  • Compact size - all models take up only 1U for lower rack costs and less space
  • Lightweight - for easier setup and portability: 7 kg (15.4 lbs)
  • Standard Phoenix connectors: analog audio outputs, aux power, alarms and GPIO
  • Remotely switchable double input (main and auxiliary input) per channel

Speaker system configuration

  • Direct drive from low impedance loads or distributed 70V/100V Hi-Z lines
  • Switchable 35Hz / 70Hz high pass filter per channel
  • Mixed configuration with Lo-Z/Hi-Z systems possible
  • Low impedance bypass mode per pair of channels

Alarms and GPI/O

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