Power Supply and Energy Efficiency: The Duecanali 804 DSP is equipped with Powersoft’s universal switch-mode power supply, which operates at up to 400VAC and incorporates Power Factor Correction. This efficient design lowers operational costs, reduces energy usage, and minimizes the need for power sequencers due to low inrush current. Additionally, the detachable AC mains cable increases installation flexibility, while Powersoft’s legendary efficiency helps reduce carbon footprint.

Comprehensive Protection System: Powersoft integrates a complete suite of protections to safeguard both the amplifier and connected equipment. These protections include:

• AC Protection: Powers down the unit if mains voltage exceeds the safe operating range.
• Clip Limiter: Prevents distorted, clipped waveforms from damaging speakers while maintaining peak output.
• DC and VHF Protections: Safeguard against infrasonic signals and non-musical high frequencies.
• Short Circuit Protection: Automatically resets after stressful conditions.
• Long-Term Limiter: Reduces steady, non-audio signals, preventing speaker damage.
• Thermal Protection: Monitors and maintains output stages up to 80°C, with variable-speed fans for cooling.

Flexible Output Configurations: The amplifier offers versatile output options, handling Lo-Z (from 2Ω) and Hi-Z (70V/100V) lines to accommodate various speaker systems. Users can configure channels in low impedance, high impedance, or bridged modes, and switch between 35Hz and 70Hz high-pass filters for optimal performance.

Advanced Digital Signal Processing (DSP):  The integrated DSP uses the TI C6000 platform to provide powerful processing for precise sound control:

• Equalizers: Independent input/output EQs with PEQ, raised cosine, and shelving IIR filters.
• FIR Filters and Delays: Achieve precise alignment and filtering, with delays up to 100ms.
• Active DampingControl™: Compensates for cable impedance, ensuring accurate sound delivery.
• Limiter Functions: TruePower™, RMS, peak, and voltage limiters protect speakers from overloading.

Remote Control and Monitoring: The Duecanali 804 DSP provides extensive remote management options:

• Software Monitoring: Via Powersoft’s ArmoníaPlus and a dedicated WebApp.
• Hardware Control: Adjust gain (26-35dB), high-pass filters, and output configurations on the unit. These options allow users to monitor and control their systems in real-time from remote locations.

Compact Design and Lightweight Build: Designed to save rack space, the Duecanali 804 DSP measures only 1 RU and weighs a mere 7 kg (15.4 lbs), making it easy to install, rack, and transport. This compact form factor offers significant savings in shipping and handling without sacrificing power or performance.
