Alimentazione Alimentatore universale ridondante con tecnologia switching 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 Protezioni complete integrate nel design dei circuiti: Protezione AC: spegnimento dell'alimentazione quando la tensione di rete è fuori scala Clip limiter: impedisce che segnali con valore di picco troppo elevato raggiungano gli altoparlanti, pur mantenendo piena potenza di picco Protezione DC: impedisce che segnali infrasonici raggiungano l'output VHF protezioni: protegge gli altoparlanti da segnali ad alta frequenza non udibili e non musicali Protezione da corto circuito: protegge l'amplificatore dal corto circuito o da altri eventi stressanti per gli stadi d'uscita Limiter a lungo termine: protegge l'altoparlante da segnali stazionari a lungo termine (senza audio) riducendo il segnale in uscita Protezione termica: temperatura di funzionamento degli stadi d'uscita fino a 80°C (176°F

Funzionalità
- 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
- 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
- Compact 1 RU for reduced rack cost and space
- Lightweight - for easier racking and shipping: 5-11 kg (11-24.3 lbs) depending on the number of BatFormers
- Standard Phoenix connectors: analog and digital input, audio outputs, aux supply, alarms, and GPIO
