Powersoft Ottocanali 8K4 DSP+DANTE

8000W/8-kanals flexibel förstärkare med DSP och Dante™ som lämnar upp till totalt 8000 W vid 4Ω, perfekt för flerzons-applikationer i medelstora och stora installationer: Ottocanali 8K4 DSP + D stöder alla kombinationer av lo-Z-högtalare, monobryggbara kanalpar och 70V / 100V Hi-Z distribution utan ytteligare transformatorer. Ottocanali 8K4 DSP + D har omkopplingsbara huvud / aux-signalingångar och erbjuder ett brett utbud av systemkontroll, larm, GPI/O och övervakningsfunktioner samt ljudformningsalternativ.

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
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 continuous variable speed fan, front to back airflow
