2-Channel Power Amplifier for Lo-Z and Hi-Z transducers
- 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
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.
Providing access to all functions yet easily set up, the Duecanali Series is versatile in use. Powersoft’s legendary efficiency saves valuable energy, keeping both operational cost and ‘carbon footprint’ at a minimum.
The Duecanali 1604 is designed to work with lo-Z (from 2 Ω ) and with 70V/100V distributed lines: any mixed impedance output loads can be realised.
Excellent sound quality and ample output power result from Powersoft’s unique approach to Class D amplification, making the Duecanali Series ideal for the main system in any venue where performance is priority. Providing access to all relevant amplifier parameter yet easily set up, the Duecanali Series is versatile in use, providing status feedback via its front panel LED display or a connected PC running Armonía Pro Audio Suite™ software.
Powersoft’s legendary efficiency saves valuable energy, keeping both operational cost and carbon footprint at a minimum: the Duecanali Series shines with outstandingly low power consumption and heat dissipation, with direct positive effects on investment – not to mention the benefits for the environment and a more eco friendly planet. The Duecanali series is designed to work with lo-Z (from 2Ω) and with 70V/100V distributed lines: any mixed configuration of low and high impedance output loads can be realized, making the Duecanali suitable for all application in installed sound reinforcement systems.
The full protection circuitry covers the investment from the most common unwanted conditions, such as: over/ under voltage, clipped signals, VHF emissions, and short circuits.
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
