MM CARTRIDGES, NOISE AND BALANCED CONNECTION


Interesting observation by Accuphase: "The most of MM type cartridges have static shield at power generator, and the static shield is connected to the negative polarity side of either channel. If MM type cartridges are set to the balanced connections, The noise amount at positive polarity side and negative polarity side inside the cartridge is varied."

"The noise cancelling effect at balanced input amp cannot be occurred, therefore MM’s Balanced connection is opened to the noise influence rather than line connection."
