Il nuovo Ottocanali 4K4 implementa una innovativa architettura per il processamento del segnale, con routing e mixing non booleani, un'equalizzazione multi-stadio con raised-cosine, filtri IIR e FIR, delay fino a 2s per il processamento in entrata e 100ms per il time alignment, guadagno e regolazione della polarità, crossover, limitatori di picco, limitatori TruePower™ limiters and Active DampingControl™. La leggendaria efficienza di Powersoft fa risparmiare energia, mantenendo costi e "carbon footprint" al minimo. Ottocanali 4K4 brilla per i bassi consumi e dissipazione di calore. Questo riduce i costi sia dalla propria alimentazione che dai sistemi di condizionamento/raffreddamento - senza contare i benefici per l'ambiente. I servizi MyPowersoft sono disponibili per questo prodotto. Alimentazione Alimentatore universale ridondante con tecnologia switch mode fino a 400 VAC con Power Factor Correction Filtro output brevettato con cancellazione ripple Bassa corrente di spunto che riduce l'assorbimento all'accensione, eliminando la necessità di costosi sequencers di potenza Cavo di alimentazione staccabile con presa IEC C19/22. 2 (16A for EU, 20 A per USA) Protezioni Prote
Progettato per non fermarsi
Powersoft has always been very focused on energy saving and the use of the Power Factor Correction (PFC) has been a trademark for improving performance and containing mains current draw and consumption.
In any amplifier output stage, the efficiency is a function of the difference in the output voltage delivered to the load and the rails voltage delivered from the power supply.

Funzionalità
- Redundant 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
- 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
- DC protection: protects against infrasonic signal at the outputs
- 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, by 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
- Fixed frequency switchmode output stage for high grade sound accuracy
- All models 2 RU for reduced rack cost and space
- Light weight - for easier racking and shipping: 14 kg / 30.8 lbs
- Standard Phoenix connectors: analog and digital input, audio outputs, aux supply, alarms and GPIO
- Remotely switchable double input (main and aux) per channel
- 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, with low impedance, per channel pair
- General Purpose Input/Output alarm interfaces: dangerous DC in the output power signal
- thermal stress
- Configurable alarm contact NC/NO per channel
- Remote AUX input / MAIN input switch
- Remote ON/OFF switch
- PWS OUT connector providing up to 24VDC
