Miniature switches „2“ are used to set the desired input capacitance for
the left (2L) and right (2R) channels. The information you need for this
will be included in the manufacturer’s specification for the pick-up system
you intend to use. Select the value which is closest to the manufacturer’s
stated figure. Note that the phono connecting lead also represents a
capacitance in the range 50 to 200 pF, depending on the manufacturer. It
is essential to set the same value for both channels. If you do not have
access to the manufacturer’s specification, a good starting point for input
capacitance is 120 pF. This is the factory default setting.
