Prezentare Amplificator Duecanali 4804
The Duecanali 4804 amplifier platform is ideal for medium to large sized installations that require high power outputs to drive subs and multiple speakers. It offers Powersoft’s renowned reliability and power density in a light, compact unit.
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
