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 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 continuous 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
- Lightweight – 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
