RAM®, Devialet's exclusive new technology (Record Active Matching) adapts in real time the phono stage parameters, including: EQ curves, mix mode, cartridge sensitivity and loading parameters. Now providing 11 new equalization curves.
This continual updating is one of the more compelling features of a Devialet unit.
