NADAC L uses a custom-designed electronic switching chip developed by the MF engineering team and fabricated at a leading European IC foundry using a special low-noise process. Functionally, it is a click-noise-free alternative to mechanical relays, combined with ultra-low TCR precision resistors for pure, transparent performance. With thermal drift reduced to virtually zero, the volume remains stable even during adjustment. By contrast, typical electronic volume chips rely on polysilicon resistors with thermal drift up to 400 ppm, whereas NADAC L’s discrete resistors achieve only 2 ppm. In essence, NADAC L provides 100% analog, noise-free, and coloration-free volume control, maintaining the most faithful and transparent reproduction.
