Descrierea Produsului

OVERVIEW CHART

The Duecanali 4804 amplifier platform is ideal for medium to large sized installations that require high power outputs to drive subs and multiple speakers. It offers Powersoft’s renowned reliability and power density in a light, compact unit.

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

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)
