Features   Specifications
The V4.25 is an Ultra high performance 4 channel Professional Power Amplifier. This class I Power amplifier is capable of producing 10,000W (4 x 2500W) of power. It has a very high power to channel density since it packs in 10,000W of power in a compact and lightweight 2U chassis. It weighs in at just 17 kgs. The amplifier uses a clever technique called SMS load balancing and hence 2 channels (channels 1 & 2) are optimized for subwoofer use. Being Class I it has very little heat dissipation and runs cool even when driven hard. It has a high damping factor > 1000. This Power amplifier is the ideal choice for high end Touring or fixed install applications requiring the advantage of less space and light weight. It combines VAL audios audiophile grade sound quality with ruggedness and reliability required on road.
