10.2 Jumper settings
The jumper fields in center of the module determine the gain. Please refer
to the table below to find the jumper setting for the desired gain. Addition-
ally, the gain is printed on the board right beside the jumper position.
The jumper field for selecting the input impedance is divided into two sep-
arate areas. The first five jumper positions (counted from the left) are for
selecting the input resistance; the remaining four positions determine the
input capacitance.
Again, the values are printed on the board right beside the jumper positions.
To setup 68 k

10.3 MM pickup systems
For MM pickup systems set the gain to 38 dB, i.e. put the jumper in the
left position (labelled '38' on the board, also see table above). For the
