description
The ability to implement any configuration with ease makes the Duecanali series extremely flexible. Powersoft's legendary efficiency saves valuable energy and keeps both running costs and "environmental footprint" to a minimum.
The Duecanali 4804 DSP+D is designed for operation with Lo-Z (from 2 Ω) and with distributed 70V/100V lines: any output loads with mixed impedance can be implemented.
A fully integrated, state-of-the-art DSP offers comprehensive system management functions. In addition to the unique Powersoft-style tone shaping and limiter functions, the DSP hardware and ArmoníaPlus software enable compliance with IEC 60849 for the critical requirements of emergency public address systems.

Features
power supply
- Legendary universal switching power supply from Powersoft with a tolerance of up to 400VAC and power factor correction
- Patented output filter with Ripple Cancellation Network
- Low inrush limiting reduces AC inrush current and eliminates the need for expensive power sequencers
- Detachable AC power cord with IEC C19/22.2 socket (16A for EU, 20A for US)
protective functions
- Fully protected circuit design with:
- Ac Protection: Shuts off the power supply when the AC grid voltage is out of the operating range
- Clip Limiter: Prevents heavily clipped waveforms from reaching the speakers while maintaining full peak power
- DC protection: protects against infrasonic signals at the outputs
- VHF Protection: protects the speakers from inaudible, strong, non-musical high frequency signals
- Short circuit protection: protects the amplifier from short circuits or other stressful events for the output circuits with automatic protection reset
- Long term limiter: protects the speaker from steady long term RMS signals (non-audio signals) by reducing the maximum output power
- Thermal protection: Amplifier operating temperature up to 80 °C (176 °F)
- Temperature-controlled, infinitely variable fan, front-to-back airflow
- Temperature prediction with LCD tracked historical behavior
General
- Fixed-frequency switching output stage for high-quality sound accuracy
