NEW LINE EVOLUTION has all the features to make your perfect sound. Quality, efficiency, stability and embedded crossovers. A Line Evolution design is the first to deliver Hi-Fi (high fidelity) even at high power with a THD (Total Harmonic Distortion) less than 0.025%. It also has a patented processing harmonic alignment that puts you above any other product in market. With a linear source with over 90% efficiency, it is capable of producing solid bass at great sound quality.

The intelligent system "Twin Source" can put to work twin sources at the same time, ensuring that the amplifier does not run out of energy when it most needs. Furthermore, they were sized with a safety margin four times larger than any other amplifier competition. So efficiently, it was possible to abolish external coolers that generated noise nuisance, especially for those who want maximum sound quality. Now it has an internal cooler that is only triggered in extreme situations.

A SounDigital bothered with all the details and innovated to abolish the EMI interferences that limit the use of radio AM and FM. Now you can listen to your favorite radio station without interferences.  This amplifier protection system now got even better. With an intelligent system that perceives and circumvents possible faults in the circuit and its oversizing, it will be unlikely that your amplifier will stop ringing.
