description

Quattrocanali 4804 offers the traditionally amazing sound quality and reliability of all Powersoft products. The patented SRM technology (Smart Rails Management) allows to maximize the efficiency of the system and drastically reduce the power consumption in any load and use condition. Quattrocanali has the lowest heat dissipation in the industry, reducing the need for external cooling devices.

Quattrocanali is designed to operate with Lo-Z (starting at 2Ω) and 70V/100V distributed lines, or any mix of the two. DSP+D versions of the Quattrocanali allow detailed control and monitoring via Armonìa, adjusting the sound and managing the system from a remote, decentralized location. Thanks to the sophisticated power supply, which enables reliable operation even when connected to a UPS, this amplifier platform can also be used in mission-critical applications such as B. fire alarm systems, trust.

Features
  • 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
