The Quattrocanali 2404 offers the traditionally amazing sound quality and reliability of all Powersoft products. The patented SRM (Smart Rails Management) technology makes it possible to maximize the efficiency of the system and drastically reduce power consumption in any load and use condition. Quattrocanali features the industry's lowest heat dissipation, reducing the need for external cooling equipment. Quattrocanali is designed to operate on Lo-Z (2Ω and above) and 70V/100V distributed lines, or any mix of the two. This amplifier platform can also be trusted in mission-critical applications, such as fire alarm systems, thanks to the sophisticated power supply that enables reliable operation even when connected to a UPS.

  • Patented output filter with ripple rejection network
  • Low inrush current limit reduces AC inrush current and eliminates the need for expensive power sequencers
  • Clip Limiter: Prevents heavily clipped waveforms from reaching the speakers while maintaining full peak output power
  • Temperature-controlled, infinitely variable fan, front-to-back airflow
  • Temperature prediction with LCD driven historical behavior
  • Fixed frequency switching mode output stage for high level sonic accuracy
  • Compact size - all models only 1U for reduced rack costs and less space
  • Light weight - for lighter shelving and shipping: 7 kg
  • Standard Phoenix connectors: analog audio outputs, aux power, alarms and GPIO
  • Remote switchable dual input (Main and Aux) per channel
  • Built-in switchable clip limiters for each channel
  • Digital Gain Attenuator Control
  • Deactivatable gate selection for each channel
  • User selectable gain/sensitivity
  • User selectable maximum power output for each channel
  • User-selectable maximum line current draw
  • Lockable setup by user selectable access key code
  • Built-in remote control via RS-485 interface allows for full diagnostics, setup and system monitoring
