Förmågan att enkelt implementera alla konfigurationer gör Duecanali-serien extremt flexibel. Powersofts legendariska effektivitet sparar värdefull energi och håller både driftskostnader och ”koldioxidavtryck” på ett minimum.

Duecanali 1604 DSP + D är konstruerad för att arbeta med Lo-Z (från 2 Ω) och med 70V / 100V distribuerade linjer: alla blandade impedansutgångsbelastningar kan realiseras.

En helt integrerad toppmodern DSP ger omfattande systemhanteringsfunktionalitet. Förutom ljudformnings- och limiterfunktioner i unik Powersoft-stil. DSP-hårdvaran och ArmoníaPlus-programvara uppfyller IEC 60849 kraven för utrymningslarm.

Power supply

Powersoft legendary 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 the 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
