TERMINATION QUALITY
Quality of the connections must be examined to ensure that high-performance, trouble-
free operation is enjoyed.
DO NOT POWER UP YOUR P100 UNTIL YOU HAVE CONNECTED YOUR INPUT/
OUTPUTS CORRECTLY FOR YOUR SYSTEM.
TURNTABLE INPUTS
Connect your turntable to the input of the P100 phono preamplier using suitable RCA
interconnect cables. Make sure you connect the red coded cable to the red RIGHT input,
and the white cable to the white LEFT input. Also make sure the RCA connectors are a
snug t and are inserted all the way in. If your turntable has an earth cable, this can be
connected to the EARTH post adjacent to the P100 input terminals.
OUTPUT TERMINALS
Connect your preamplier or integrated amplier to the output of the P100 using suitable
RCA or XLR interconnect cables.
If using RCA cables, make sure you connect the red coded cable to the red RIGHT input,
and the white cable to the white LEFT input. Also make sure the RCA connectors are a
snug t and are inserted all the way in.
If using XLR cables, make sure you connect the RIGHT XLR input and LEFT XLR inputs to
the right and left inputs of your preamplier or integrated amplier respectively. Also
make sure the XLR connectors click into place.
NOTE: DO NOT connect XLR and RCA at the same time, use only one or the other. DO
NOT connect the output of the P100 to a preamplier phono input. Connect only to line
level inputs such as CD, Tuner, Aux, etc.
CONNECTING THE MAINS SUPPLY
Firstly, check that the mains supply voltage printed on the rear of this preamplier is
similar to the mains supply voltage in your area. If in doubt, please consult your Plinius
dealer. Mains supply power connection is via the plug-in lead supplied with your P100.
Where possible, check the wall outlet is switched OFF, then connect the local mains plug
end of the lead to the wall outlet. Check the P100 is switched OFF, and connect the IEC
end of the cable to the IEC socket at the back of the P100. With the cord fully connected,
switch the wall outlet ON.
Now that your P100 is congured correctly, switch the power switch on the rear panel
to ON. The display LED will illuminate. You can now enjoy your new Plinius P100 Phono
Preamplier.
NOTE: This unit must be connected to a mains socket outlet with a protective earthing
connection. The wall outlet socket or mains switch must be accessible at all times in case
of emergency.

Care & Maintenance
With simple care and maintenance your Plinius product can be kept looking and
operating like new for many years to come.
MAINTAINING THE CONNECTORS
The surface of RCA connectors may tarnish when exposed to the environment. Poor
connector condition may degrade audio performance. 'RCA caps', 'RCA shorting caps' and
connector cleaning products can be used to reduce environmental degradation.
NOTE: DO NOT use RCA shorting caps on output connectors. Use RCA shorting caps on
unused input connectors only. Non-shorting RCA caps can be used on any unused input or
output connectors.
MAINTAINING THE SWITCHES
Switches should be maintained by using each various switch setting periodically. Even if a
switch or a switch setting is not used, it is a good idea to toggle small switches and turn
rotary switches though the full range of the switch several times in succession to keep
the contacts active. Performing this simple action will promote longevity of the switch
contacts.
SURFACE CLEANING
From time to time you may wish to clean the surface of your Plinius equipment to remove
dust, or any material build up from the atmosphere or on commonly used controls. Your
Plinius product is made up of parts that have a hard anodised or a powder coat nish and
will clean easily without being damaged.
Cleaning should be carried out using a soft cleaning cloth, dry or with either a small
amount of water or a very mild surface cleaner, while observing the following guidelines:
ǞAs a safety precaution, always switch the equipment o prior to cleaning
ǞAlways use a cloth that is soft and clean
ǞNever use abrasives or polishing compounds anywhere on the unit
ǞNever apply liquid directly to the surface of the unit
ǞUse the cloth dry or with mild surface cleaners of either liquid or foaming type
ǞApply only small amounts of cleaner to the cloth
ǞDO NOT rub the surface but wipe clean only. Excessive rubbing may dull powder coat
or wear the screen printed text.

Troubleshooting
NO SOUND FROM THE UNIT
If the unit is not reproducing audio take the following steps:
ǞCheck your turntable is correctly connected to the P100. Refer to the Installation &
Operation section.
ǞCheck your turntable is rotating and the tonearm is lowered fully onto the record.
ǞCheck your preamplier or integrated amplier is set to select the correct source
input. Adjust the source selector for the P100 as the source component.
ǞCheck the volume. Turn the unit volume up to a point just below the normal listening
level. DO NOT turn the volume up to maximum in case the sound begins to come
through the speakers.
PHASE (OR POLARITY)
It is important to achieve good stereo imaging in your listening room. If you experience
poor stereo image and/or a lack of bass, check that the loudspeaker wiring has been
connected correctly. If in doubt, consult your Plinius dealer for advice.
Naturally it is also important to make sure all the leads carrying signals for the RIGHT channel
loudspeaker are connected to the RIGHT input to the amplier from your preamplier or
integrated amplier and P100. Signals for the LEFT channel should be wired in a similar
fashion.
POWER FAILURE
The unit may have suered mains fuse failure. In the unusual event that the P100 mains
/ line fuse blows, you must rst establish the cause of this failure, such as a power surge,
before replacing the fuse with one of the same rating and type. Should the P100 continue
to suer mains fuse failure, there may be a major problem and you should contact your
Plinius dealer.
The mains / line fuse is tted within the mains connector on the rear of the P100.
Following removal of the IEC plug, a small drawer may be removed by levering it out with
a at blade screwdriver. The fuse tted should be rated as specied on the rear panel.
IMPORTANT: DO NOT FIT A FUSE WITH A HIGHER RATING.
