2-Channel Amplifier Platform
- 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
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.
Compact and lightweight, it can be used as an addition to existing systems to enhance audio reproduction in small to medium sized areas. As a standalone unit, the Duecanali 804 amplifier platform shines with outstandingly low power consumption and thermal dissipation.
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
