THE NEW EVO LINE is here to stay and has every resource to produce the perfect sound. Quality, efficiency, stability, onboard crossover and innovative design.

The Evo Line is the first on to have Hi-fi (high fidelity) performance even in the highest power rates with a THD (Total Harmonic Distortion) under 0,025%. It also has a patented harmonic alignment processing that places it above any similar product in the world market.

Now featuring a linear power supply with an efficiency over 90%, it is able to produce solid and longer bass sounds with the lowest consumption ever. When in standby, it can consume up to 5 times less than other products in the market.

The intelligent “twin source” system makes two twin power supplies work simultaneously, assuring your product to maintain power when it needs the most. Besides that, they were designed with a safety margin 4 times higher than the concurrent products. With that great efficiency, it was able to remove the external coolers which used to generate an inconvenient noise, what pleases who looks for the best sound quality. It has just one internal cooler now, which starts only in extreme conditions.

Soundigital has taken care of every single detail and has put an end to the EMI interference which used to limit the use of AM and FM radio. Now you can listen to your favorite radio station with no interferences.

For those who really enjoy the sub-bass, the Evo Line counts with a higher capacitance than the other similar products what guarantees the sustenance of the bass sounds in your favorite songs.

It has a precise cone control with impressive linearity what makes this improvement also very clear in the mid-bass which are widely present in “Trio Elétrico” systems, improving the tone and aggressiveness of the hits.

The protection system has got even better. It is an over dimensioned intelligent system that perceives and works its way around possible failures in the circuit, making it extremely difficult for your amplifier to stop working. Soundigital takes it so seriously that we guarantee not even output short circuits will make it stop.

Innovate you too and acquire what’s best in the audio world.
