Explanation of terms
MM/MC cartridge
There are two types--MM (Moving Magnet) and MC (Moving
Coil)--of cartridges for turntable. As the output levels for these
two types of cartridges differ, the setting of the phono
equalizer that is mounted in this unit must be switched
according to the type of cartridge for your turntable. Change
this setting in the “PHONO” section of the setting menu.
