Category: SKU: AM/POW/PWS01

The brand new Duecanali Series shines with outstandingly low power consumption and heat dissipation, with direct positive effects on investment. It is aimed at larger two-channel install applications and it is able to provide more than 16 different possible output configurations including Lo-Z, Hi-Z, bridge mode, and parallel mode.

Compact and lightweight, it can be used as an addition to existing systems to enhance audio reproduction in small to medium sized areas. As a standalone unit, the Duecanali 804 amplifier platform shines with outstandingly low power consumption and thermal dissipation.

Power supply

  • 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 operating range
  • Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
  • 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 continuous variable speed fan, front to back airflow

General

  • Fixed frequency switchmode output stage for high-grade sound accuracy
  • Compact 1 RU for reduced rack cost and space
  • Lightweight – for easier racking and shipping: 7 kg (15.4 lbs)
  • Standard Phoenix connectors: analog and digital input, audio outputs, alarms and GPIO
  • Remotely dimmable inputs 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

  • General Purpose Input/Output alarm interfaces:
    • dangerous DC in the output power signal
    • thermal stress
  • Configurable alarm contact NC/NO per channel
  • Remote ON/OFF switch
