With the (red) jumper placed to the right  side of the jumper sockets
(JP101) and (JP301) the input impedance will be 100 Ohm in MC
mode.
With the jumper placed to the left sider of the jumper socket the input
impedance will be 20 Ohm in MC mode.

The input impedance in MM mode is 47kOhm/200pF.

Switching between MM and MC ( yellow  illustration )
The selection of MC or MM is made with jumpers JP100, JP102,
