Soundigital SD400.4S EVOII
The new 400.4S now features a very flexible variable crossover, high level input, improved potentiometers and a lot more!
Now featuring a linear power supply with an efficiency over 90%, it is able to produce solid performance with the lowest current draw ever.
The intelligent “twin source” system makes two twin power supplies work simultaneously, assuring your product to maintain power when it needs the most.
It has a precise cone control with impressive linearity.
The protection system is now 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.
Innovate you too and acquire the best in the audio world.
