Quattrocanali 2404 erbjuder både den traditionellt fantastiska ljudkvaliteten och tillförlitligheten som man finner hos alla Powersoft-produkter.

Den patenterade SRM-tekniken (Smart Rails Management) gör det möjligt att maximera systemets effektivitet och drastiskt minska strömförbrukningen i alla belastnings- och användningsförhållanden. Quattrocanali har den lägsta värmeavledningen i branschen, vilket minskar behovet av externa kylanordningar.

Quattrocanali är utformad för att fungera med Lo-Z (från 2 Ω) och 70V / 100V distribuerade linjer, eller någon blandning av de två.

Denna förstärkarplattform kan också lita på uppdragskritiska applikationer, såsom brandlarmsystem, tack vare den smart konstruerade strömförsörjningen som möjliggör tillförlitlig drift även när den är ansluten till en UPS.

MyPowersoft-tjänster finns tillgängliga för denna produkt

Power supply
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
Temperature forecast with LCD traced historical behavior
