Description
The ability to implement any configuration with ease makes the Duecanali series extremely flexible. Powersoft's legendary efficiency saves valuable energy, keeping both operational cost and carbon footprint at a minimum.
The Duecanali 804 DSP+D is designed to work with Lo-Z (from 2 Ω ) and with 70V/100V distributed lines: any mixed impedance output loads can be realized.
For Installed Sound Reinforcement systems, the Duecanali Series offers remarkably low power consumption and heat dissipation, in addition to Powersoft's renowned audio quality and reliable performance — all in a compact, lightweight unit. The Duecanali is a Class D power amplification platform designed for larger 2-channel install applications. While all Duecanali versions deliver Powersoft's renowned reliability and power density in a light, compact unit, Duecanali DSP+D versions also offer built in, state-of-the-art DSP, as well as Dante, providing additional system flexibility and extensive amplifier control.
A fully integrated state-of-the-art DSP yields extensive system management functionality. In addition to sound shaping and limiter functions in unique Powersoft style, the DSP hardware and ArmoníaPlus software enable compliance with IEC 60849 for the crucial requirements of sound systems for emergency purposes.

Features:
Power supply
- Powersoft legendary 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 the operating range
- Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
- DC protection: protects against infrasonic signal at the outputs
- 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, by 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
- Temperature forecast with LCD traced historical behavior
General
- Fixed frequency switchmode output stage for high grade sound accuracy
- Compact size - all models only 1 RU for reduced rack cost and space
