PLACEMEN
PLACEMENT AND VENTILATION
PLACEMENPLACEMEN
Your Plinius 9100 may operate at a moderately high temperature when being driven hard. The ideal
location is upon a rigid stand, or floor mounted away from direct contact with any temperature sensitive
materials or deep pile carpets. Ventilation through and around the amplifier should also be kept
unimpeded, so ensure that the heat vents (slots in the lid and base) are not covered or restricted in any
way.
The Plinius 9100 design incorporates a very high level of mechanical de-coupling of the input and output.
It can however still be influenced by acoustical feedback in the operating environment. The use of
acoustic cones, or a suitably spiked amplifier stand or table, may further enhance the performance of this
amplifier. Consult your PLINIUS

It is important that you connect your loudspeakers (outputs) and source components (inputs) to the
Plinius 9100 Integrated Amplifier correctly to ensure the amplifier is not damaged, and sounds its best
with your system. Now that you have read and familiarised yourself with the connections on the back of
the amplifier, as covered in the previous section, we will describe in detail the way in which you can
connect the amplifier to your system.
Connect your tuner, CD player, tape decks, etc, to the corresponding RCA inputs on the back of the
Plinius 9100. Make sure you connect the red coded cable to the red RIGHT RCA input, and the black (or
white) cable to the black LEFT RCA input. Also make sure the RCA connectors are a snug fit and are
inserted all the way in.
Next, connect your loudspeaker wires to the output posts. Connect your right loudspeaker (i.e. the one on
the right of you when seated in your normal listening position) to the right output terminals, ensuring that
the red positive (+) terminal is connected to the red terminal on your loudspeaker. Do the same with the
black or negative (-) terminals.

In order to record music to tape, or some other line level recording device, these devices will need to be
connected to the tape 1 and tape 2 outputs. Turn the record selector on the front panel to the input you
wish to record from, and the amplifier will now send signal to both tape 1 and tape 2 outputs. Note that
the volume control does not adjust the recording level - this is done at the recording device itself.

It is important to achieve good stereo imaging in your listening room. By observing the wiring
instructions above, each power amplifier/loudspeaker combination should be in phase. If you experience
poor stereo image and/or a lack of bass, check that the loudspeaker wiring has been connected correctly.
We recommend that you use one of the easily obtainable ‘test discs’ to help you ensure both phasing and
channel orientation are correct. If in doubt, consult your PLINIUS
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 amplifier from your preamplifier or CD player etc. Signals for the
LEFT channel should be wired in a similar fashion.

Provided with your Plinius 9100 is a three function remote control. The two buttons at the top of the
remote adjust the volume level, and the button below switches the amplifier in and out of mute. Two AAA
batteries power the remote, and these are replaced by removing the two posi-drive screws on the rear face
of the remote that hold the battery compartment in place. The bottom end of the remote is now free to
slide down for access to the batteries. Replace the two batteries, taking care to refit the new ones with
correct polarity.

On most tape decks, any signal recorded is sent to the tape outputs so that the signal level of the
recording can be monitored. Should the user accidentally try to record the tape decks own output,
feedback howl usually results. The Plinius 9100 Tape Lockout feature prevents this situation from
damaging your system speakers by muting the power amplifier.
FUSE PROTECTION

When any rail fuse is damaged one or more fuse warning LED’s will light. These LED’s are located next to
the fuse that has blown. To replace the fuse, steady the amplifier, then firmly push in the round fuse cap
with your fingers. When the cap cannot push in any further, rotate the cap anticlockwise (to the left) until
it comes to a stop. Release inward pressure on the fuse cap and it can now be removed from the
amplifier. If any of the rail fuses need to be replaced, do so only with 5 amp normal blow fuses.
To re-fit the fuse, insert the fuse and gently turn it as far as possible anticlockwise (to the left). Now push
the fuse cap in firmly, then turn clockwise (to the right) until it comes to a stop. Release inward pressure
on the cap and the fuse will be fitted securely.

Your Plinius 9100 Integrated Amplifier is designed for use with high fidelity loudspeakers. It should not
be used to operate with any other type of appliance or equipment.
Choice of loudspeakers is one of personal taste, providing the chosen loudspeakers are suitable for use
with your amplifier. Be certain that your loudspeakers can handle most of the rated output power of this
amplifier. You may find loudspeaker specifications confusing or misleading, so you should discuss this
with your audio dealer prior to purchase. As a general rule, the use of high power (200 Watt RMS or
greater) loudspeakers is recommended and desirable. However, our experience indicates that medium to
low power loudspeakers (100 to 200 Watt RMS) are quite often suitable for use on this amplifier, provided
the volume is maintained at a level where no distortion is audible.
Impedance of the loudspeaker load is important to ensure the rated performance of this amplifier. Any
combination of loudspeakers may be used, but the total average impedance load for each channel should
be within a range of 4 to 8 ohms. Again, if you have doubts about the impedance of your loudspeaker
configuration, we recommend you speak to your PLINIUS
PLINIUS dealer.
