Input Customization
The inputs of the PL-P can be
customized to suit specific
installation requirements and
listening preferences through
modifying the positions of internal
jumpers inside the PL-P case.
To gain access to the inside of the
PL-P case, ensure that the PL-P is
powered off, disconnect the PLP-
CCC3 AC power supply unit and
remove the top plate by removing
the 4 hex screws using the supplied
ISO/Allen 2.5 mm key. Lift the top
plate off the PL-P case carefully. If
the unit has just been powered off,
please wait 5 minutes
for the vacuum tubes to cool down
before handling any item inside the
PL-P case to avoid potential burns
or injury.
Input customization options are as
follows:
This diagram shows the different
jumper positions for the various
different options within the PL-P. To
install a jumper, place it over BOTH
of the pins of the corresponding
selection so as to join them
together.
The different jumpers within the PL-
P can be used to set various
different customization settings
according to the installation and the
user’s preferences.
1. Moving-coil/Moving-magnet
cartridge selection
Principally, there are three different
solutions here, these being MM, MC
(with an internal or associated
transformer) or MC (without an
internal or associated transformer).
The first two solutions will give an
output of several mV and the third
will give only a fraction of this level.
The Phono input of the PL-P is
fitted with high precision
transformers. These will allow the
user either to adapt the input
sensitivity without affecting the
signal-to-noise ratio or, in the case
where persistent hum is apparent,
can make the phono input of the
PL-P floating.
The three different solutions are as
follows:
