Powersoft – D4804 DSP+DANTE

The brand new Duecanali Series shines with outstandingly low power consumption and heat dissipation, with direct positive effects on investment. It is aimed at larger two-channel install applications and it is able to provide more than 16 different possible output configurations including Lo-Z, Hi-Z, bridge mode, and parallel mode.

Power supply

• Universal switch mode power supply up to 400V_AC 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 ArmoníaPlus
• Dedicated Web App
