MM or MC is type of the cartridge.
Some vendor sell the turntable with tonearm and cartridge, some are not.
MC/MM cartridge output signal is so weak, so need a MC/MM phono amp to increase the signal voltage.
Becoz 609 no phono input, so u need buy a phono amp, a turntable with tonearm and MM cartridge (I suggest use MM cart at beginner moment) and a pair of signal cable (for connect phono amp to 609)
