Audiocenter VA801 Power Amplifier The Audiocenter VA1201 Power Amplifier is 2 Channel, 1050w/ch 4Ohm Sensitivity:0.775V/36dB/32dB,Filter capacitor capacity:10000μf/80V×8,Damping factor:≥350,Slew rate:≥25V/μs A - Guard protection system: A-Guard is AUDIOCENTER comprehensive protection system which includes overload limiter with optimized attack time. Unlike other solutions which depend on separate circuits to address different problems, A-Guard was developed as centralized solution where all protection requirements work together in perfect harmony. A-Guard is only applied when it's necessary to protect the amplifier. This is why VA amplifiers are able to sustain full power output even under complex capacitive loads. SMART OVERHEAT MANAGEMENT: AUDIOCENTER Smart Overheat Management gives VA series the ability to perform in high temperature environments without thermal shutdown. This unique circuitry monitors the amplifier's temperature in real time and when the safe operation of the amplifier is compromised, the output power is reduced but not shutdown.
