1) MM – MC Setup: depending of the type of your cartridge, you can select the Input

2) Input impedance choice: These settings apply to both MM and MC cartridges.
They allow you to adapt the musicality of your PH100 to your system.
• For an MM cartridge, put 3 and 4 OFF.
• For a high level MC cartridge (MCH), put 3 ON, and
4 OFF.
• For a low level MC cartridge (MCL), put 3 and 4
ON.
• To select a 47 k resistor, put 1 ON.
• To select a 100 k resistor, put 1 OFF.
• To select a condensator of 100 pF, put 2 ON.
• To select no condensator, put 2 OFF.
Warning: the congurable input resistor is unrelated to the output resistor of
your cartridge (very low compared to the congurable input resistor).
