R-2R Ladder ultra-high precision 32-bit depth DAC with FPGA “Extraudio System”, which produces an analog sound, full of nuances, without digital harshness, without any type of error.  Thanks to the depth of 28 to 32 bits, the resistance ladder is corrected through the second FPGA that is only responsible for converting and correcting the linearity of the four DAC modules. Then we have another ARM FPGA with the latest technology for the sample rate functions, selection of inputs and conditioning of digital signals, freeing the main FPGA from all this work, a unique sound is achieved and with very low voltage steps on the R-2R ladder, approximately each step is equivalent to a tiny jump of 0.04 Volts from MSB (Most Significant Bit) to LSB (Least Significant Bit), all this added to the R-2R resistor ladder of our DAC,s technology using about 600 pieces of 0.01% tolerance Vishay Foil Resistors ® of the highest quality, handmade soldered in Europe with temperature control, with high quality tin, make the sound even more exact, but very analog and musical, with a lot of texture and spatiality, very whole and without digital deficiencies in digital steps, the lower the step height, the higher the quality and smoothness in the digital conversion, that’s why we use a 32-bit depth.

Finally, we have a microcontroller that takes care of all the other control functions, to put it another way, there are 3 motors within the same product both in DAC1 and DAC2.
