Duecanali 4804 DSP +D

2-Channel High Performance Amplifier Platform with DSP and Dante™

This amplifier platform is ideal for medium to large sized installations that require high power outputs to drive subs and multiple speakers. Duecanali 4808 DSP+D offers Powersoft’s renowned reliability and power density in a light, compact unit.

Built in state of the art DSP, in conjunction with Dante, allows flexibility during installation and extensive controllability.

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 continous 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
  • Light weight - 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

Digital Signal Processing

  • TI C6000 DSP platform
  • AD/DA converter: dual 24bit @ 48 kHz Tandem® architecture
  • Input/output independent equalizers per channel providing PEQ, raised cosine, shelving IIR filters as well as custom output FIR filters
  • Delay up to 100 ms for time alignment
  • Active DampingControl™ for cable compensation
  • Peak, RMS voltage, RMS current, TruePower™ limiters

Remote management

  • Control and monitoring through Armonía Pro Audio Suite™
  • Dedicated Web App

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)
