3.4 Cartridge Loading
The resistive and capacitive input load presented by
the SuperLine to the pick-up cartridge can be adjusted
by inserting a combination of “load plugs” into the
appropriate sockets in the rear panel.
The appropriate load plug combination will depend on
both the manufacturer’s recommendations for the pick-up
cartridge in use and subjective preference.
Each load plug is constructed from a 5-pin DIN plug that
contains the appropriate passive components. A label on
each load plug identifies its load value.
Seven standard load plugs are supplied - four resistive
and three capacitive - to provide 20 combinations
(including the default input loads applied when no load
plugs are inserted). Table 3.5 lists the standard load plug
combinations.
Note: In addition to the standard load plugs supplied, 470Ω
and 560Ω resistive plugs are also available on request.
Other values may also be created either by modifying
standard plugs or manufacturing new ones. Contact your
retailer or local distributor for more information.
Always ensure that resistive and capacitive load plugs are
inserted in the correct socket.
Note: The SuperLine incorporates 10kΩ resistance and
100pF (0.1nF) capacitance loads internally. With no load
plugs fitted these values constitute the default load.
