XP-15 Owner’s Manual
do best with Moving Coil selected. Only one type of input may
be selected as “ON”, the alternate input type must be “OFF”. If
Moving Magnet is selected as “ON”, all eight (8) resistive loading
switches should typically be selected “OFF”.
Once you have selected an input type you will need to attach the
RCA connectors from your turntable to the appropriate input on
the XP-15 (Moving Magnet or Moving Coil). You will also need
to attach the ground connection from your turntable to the single
white five way binding post on the XP-15. The XP-15 will function
without this connection made up but the background noise level will
likely be excessive.
If you have selected Moving Magnet you will also need to select
capacitance. It will be impossible to give suggestions for correct
capacitance with any given cartridge, due to the huge variation in
capacitance on the cables. The optimal value is selected by listening.
There are three capacitive loading switches with values of 330pF,
220pF and 100pF; these are in addition to a fixed value of 100pF.
You may select any switch or number of switches, the values are
additive. The range of values available is 100pF – 750pF. The
correct value is that which gives the best overall tonal balance.
Typically if the cartridge sounds too bright more capacitive loading
will be required. The typical Moving Magnet cartridge has a fairly
predictable output, the XP-15 gain in moving magnet is fixed at
46dB.
Resistive loading for moving magnet is fixed at 47k-ohm. If you
require something other than 47k-ohm, please contact the factory. It
is suggested that all moving coil loading switches be set to off.

Moving Iron cartridges typically load at 47k-ohm and are not at all
sensitive to capacitive loading. It is suggested that you treat them as
moving coil cartridges if their output permits.
