A high-output cartridge is used (MM
or MC with associated transformer)
and the internal transformer of the
PL-P bypassed using jumpers ST4
and ST9 and removing MM or MC
jumpers on ST2 and ST6. In this
case you can use a high-
impedance input of 470 kOhms or
lower it to the standardized
impedance of 47 Ohms by means
of jumpers ST41 and ST91
• If earth loop problems cause
permanent hum, the high-quality
internal transformers can be
used using jumpers ST4 and
ST9 and with MM or MC jumpers
on ST2 and ST6. Remember to
remove the 47kOhms jumpers
ST41 and ST91 if installed as the
transformer presents a uniform
47 kOhms throughout the
bandwidth. In this case either
one or both channels can be
grounded using jumpers ST3
and/or ST8.
• A low-output cartridge is used
(MC without associated
transformer) in which case the
internal transformers of the PL-P
should be used by means of ST4
or ST9 and with MM or MC
jumpers on ST2 and ST6. Either
channel can be grounded or the
input can be left floating
according to the installation using
ST3 and/or ST8.
2. Moving-coil phono
cartridge, additional
resistive loading
options
The PL-P offers the following
resistive and capacitive loading
options to optimize the performance
of most available moving-coil phono
cartridges. A specific value can be
selected by installing the jumpers in
the appropriate position, as per the
internal jumper diagram.
The resistive loading options
available are:
• 33 Ohms
• 100 Ohms
• 330 Ohms
•
47
kOhms (without jumper
installed)
These resistive loads can be
combined in different combinations
according to the jumper positions.
3. Moving-magnet phono
cartridge, additional
capacitive loading options
The PL-P offers the following
capacitive loading options to
optimize the performance of most
available moving-magnet phono
cartridges. A number of values can
be selected by positioning various
jumpers for each channel, as per
the diagram on the previous page.
The capacitive loading options
available are:
• 100 pF
• 220 pF
• 470 pF
These capacitive loadings can be
combined depending on the
positions of the jumpers.
4. RIAA Equalization options
The PL-P can be selected to work
with one of two RIAA equalization
curves by installing jumpers ST1
and ST7 in the appropriate
locations inside the PL-P for the left
and right channels respectively.
Please refer to the jumper diagram.
