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 series amplifiers are able to sustain full power output even under complex capacitive loads. 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. After many hours R&D research, AUDIOCENTER has created new circuitry to eliminate the Class H cross switching distortion. We have done this by the accurate time alignment compensation on the Critical switching path. The result is the same low distortion as Class AB.In fact, all VA series amplifiers enjoy less than 0,1% THD at 16KHz, half power. That's why the sound of the VA series is so clean and natural. We call it Class H+ and it's only available in AUDIOCENTER amplifiers. The advantages of Class H+ can be seen and measured in real world. Phase and Frequency response performance are close to perfect and we clearly lead the category, thanks to our Class H+ topology. ● With a slew rate of 25V/us, VA series amplifiers are among the fastest in the market. ● AUDIOCENTER A-Guard input overload limiter is efficient up to 9V, when many competitive circuitries are over-driven above 3V.
