FRONT PANEL LAYOUT SHOWING VOLUME KNOB, RECORD
AND SOURCE SELECTORS, DISPLAY LED’S AND MAINS SWITCH
MAINS SWITCH
The heavy-duty rocker switch to the left of the panel turns the Mains/Line Power to the amplifier ON or
OFF. Depress the right hand side of the switch to turn the amplifier on. The amplifier draws a moderately
high current when switched on, so it is not good practice to rapidly turn the Mains switch on and off
repeatedly.
POWER LED
An LED in between ‘PLINIUS 8200’ indicates that the power is on. When first switched on, the power LED
will pulse for ten seconds - this is an initialisation sequence, after which the power LED remains lit during
the time the amplifier is powered on.
SOURCE SELECTOR
This rotary switch enables selection of any of the five different inputs available on the back panel. This
selection is fed to the speakers via the output posts on the rear of the amplifier. Note that in standby
mode no input is selected.
6
RECORD SELECTOR
This rotary switch allows recording of any of the five different inputs available on the back panel. Note that
when recording, the source that is being listened to will not be interfered with. For example, it is possible
to be listening to the CD input whilst recording from the TUNER input. Two tape decks can be connected
and dubbing in either direction is possible. Note that in standby mode no input is selected.
VOLUME CONTROL KNOB
The volume control is an ALPS motorised unit that will accurately convey the source signals to the power
amplification stage of the Plinius 8200. The knob can be adjusted manually or with the remote control
supplied. When using the remote control to alter the volume level, stab the button to make small
adjustments, or hold the button down to continuously adjust the volume.
MUTE/REMOTE LED
The LED directly below the volume knob serves two purposes. Firstly, whenever the Plinius 8200 is in
mute, the LED will be lit. Secondly, whenever a button on the remote control is used, the LED will light to
show the amplifier is receiving signal.
7
This panel incorporates all the terminals for connecting the input signals from your CD player, tuner, etc,
and the outputs to the loudspeakers and mains supply.
Please remember that your Plinius 8200 Integrated Amplifier is a high quality electronic instrument
capable of an exceptional level of performance. Be sure that you understand your system’s requirements
fully before you make any connection to this amplifier.

REAR PANEL SHOWING INPUT AND OUTPUT TERMINALS, MUTE AND
PROCESSOR BYPASS SWITCHES, AND MAINS SOCKET.
INPUT TERMINALS
The input terminals for your Plinius 8200 Integrated Amplifier are easily accessible along the top of the
rear panel. These standard RCA terminals are for use with unbalanced signals from phono, CD, tuner, and
two tape decks. The phono inputs are suitable only for low level input phono turntables, while the rest are
all ‘line level’ inputs, suitable for audio equipment from most manufacturers. Consult your PLINIUS dealer
for further advice if required.
OUTPUT TERMINALS
Connections for the loudspeakers are provided on the right hand side of the rear panel. Two parallel pairs
of five way binding posts for each channel are fitted – these provide ease of use with bi-wiring and
multiple cables requiring a large contact area.
8
TAPE OUTPUTS
These RCA outputs are situated next to the tape RCA inputs, and are provided to interface to a pair of line
level recording devices. The position of the record selector on the front panel determines from which
device a recording is being made. As these tape outputs are always ‘live’, both can be used to record the
chosen signal at any time.
MUTE SWITCH
The mute switch enables disconnection of the output, without the need to use the remote control. When
the amplifier is in mute, the LED on the right of the front panel will light.
PROCESSOR SOURCE AND RETURN
These RCA connections are for use with a multi-channel sound processor. They are provided so that you
can use the Plinius 8200 as either two channels in a multi-channel environment, or to send signal through
the amplifier to an external processor.
PROCESSOR SWITCH
This switch is used in conjunction with the processor source and return terminals, and controls whether
the amplifier is used via the normal inputs or the processor return input.
PRE OUT OUTPUT
The Pre-Out connection is provided to enable the Plinius 8200 to be connected to an external power
amplifier. The signal from this output is line level, and as such is not amplified by the power stage of the
Plinius 8200.
MAINS POWER CORD IEC SOCKET
This connector is where the mains supply cable from your wall connects to the amplifier. You will notice
that a fuse holder is mounted within this connection, and it holds a mains fuse to provide surge and
overload protection for your amplifier.
RAIL FUSES
These tubular fuse holders house the positive and negative rail protection fuses. Depress and turn anticlockwise to open. An LED is fitted next to each fuse holder to indicate a blown fuse.
PHONO EARTH POST
This is a chassis connected gold-plated earth post for use with certain phono turntables.
9
PLACEMENT AND VENTILATION
Your Plinius 8200 operates at a moderately high temperature, especially 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 8200 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 dealer for further advice if required.
MAINS VOLTAGE CONNECTION
Firstly, check that the mains supply voltage printed on the rear of this amplifier 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 supplied plug-in lead. A standard IEC socket connects the
mains power at the amplifier end, while a local mains plug is required at the wall end.
The wiring code used inside all Plinius product is:
Green to Earth/Ground
Blue to Neutral
Brown to Phase/Live
Should a ‘local’ plug need fitting to the wall end of the lead, ensure that a suitably qualified service
technician wires the plug correctly.
IMPORTANT:
DO NOT POWER UP YOUR AMPLIFIER UNTIL YOU HAVE
CONNECTED YOUR INPUT/OUTPUTS CORRECTLY FOR
YOUR SYSTEM, (AS EXPLAINED IN THE NEXT SECTION).
10
It is important that you connect your loudspeakers (outputs) and source components (inputs) to the
Plinius 8200 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 now 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 8200. 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.
LISTENING TO MUSIC THROUGH AN EXTERNAL PROCESSOR
Connect the external processor’s input to processor ‘source’ on the back of the Plinius 8200. Next
connect the external processor’s output channel that the Plinius 8200 will power (i.e. front, rear, centre, or
sub) to processor ‘return’ on the rear panel.
Set the processor switch to ‘processor in’ and set the source selector on the front panel to the
corresponding device you wish to listen to. The signal from the device being listened to will now be sent
to the processor, split into multi-channel, and a component of that signal will be amplified by the Plinius
8200. The other channels would be connected to other amplifiers.
Note that in this configuration it is best to set the channel levels as required on the processor, then use
the volume control on the front of the Plinius 8200 to control the level to the whole system.
AMPLIFYING TWO CHANNELS FROM A PROCESSOR (DVD/VIDEO)
Connect the external processor’s output that the Plinius 8200 will power (i.e. front, rear, centre, or sub) to
the processor ‘return’ input on the rear panel. Leave processor ‘source’ disconnected.
Set the processor switch to ‘processor in’ and the Plinius 8200 will simply amplify the signal it receives
from the processor. Note that in this configuration the volume control on the Plinius 8200 will not have
any bearing on the signal level, as the external processor will have control over the entire system volume.
11
SETTING THE PROCESSOR SWITCH
The processor switch needs to be in ‘bypass’ when listening to music directly from selected source inputs
such as CD or tuner. If you are not using an external processor in either way as described above, ensure
this switch is set to ‘bypass’. The Plinius 8200 does not amplify any input other than processor ‘return’
when this switch is set to ‘processor in’ mode.
RECORDING MUSIC
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.
USING PRE OUT
A line level output is provided on the back of the Plinius 8200. If you wish to use the Plinius 8200 as a
pre-amp only, or to send signal to another amplifier, fit the interconnect cable to the pre out outputs. Note
that the pre out connections provide signal from whatever the source selector knob is currently set to.
TERMINATION QUALITY
Quality of the connections must be examined to ensure that high-performance, trouble-free operation is
enjoyed. Check that the connections are tight but do not over tighten. If bare wires are used make sure
that no loose strands of wire short across the other terminals or the amplifier chassis. When using plugs
such as bananas, be sure to use good quality plugs with a firm fit.
BI-WIRING
Bi-wiring uses two pairs of loudspeaker cables for each channel loudspeaker. You will notice that the rear
panel of your Plinius 8200 has two pairs of output terminals for this purpose. When using bi-wires,
always connect positive (+) to positive (+) and the same for the negative (-) terminals.
PHASING (OR POLARITY)
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 dealer for advice.
12
To achieve a sound performance that is correctly aligned to your room, make sure all of 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.
CONNECTING THE MAINS SUPPLY
Now that your Plinius 8200 Integrated Amplifier is configured to your system correctly, the mains cable
can be plugged into the IEC socket on the back of the amplifier. Ensure that the processor switch on the
back panel is correct for your intended usage (normally ‘bypass’), and check the speaker cables are
connected correctly. Flick the power switch on the front panel to the right. The power LED will pulse for
five seconds as the internal microprocessor allows the internal circuitry to stabilise before opening the
mute circuit. You can now enjoy your new Plinius 8200 Integrated Amplifier.
WARM-UP PERIOD
You will find that the Plinius 8200 will become noticeably ‘warmer’ in sound after being on for a period of
time. We usually recommend waiting at least 24 hours before expecting the best quality of sound
reproduction from your amplifier. Also, as the Plinius 8200 uses very little power while on, we suggest
leaving the unit turned on so that it will always be at it’s sonic best.
13
REMOTE CONTROL
Provided with your Plinius 8200 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 holding the
bottom plate in place. The rear panel of the remote can now be slid downwards. Replace the two
batteries, taking care to refit the new ones with correct polarity.
PHONO GAIN ADJUSTMENT
The phono stage can also be set to high or low gain to suit your phono turntable specifications (high gain
is the factory setting).
Disconnect the lead from the IEC socket on your Plinius 8200 and make sure the Mains switch is OFF.
Carefully remove the lid by undoing the 4 posi-drive screws underside. Locate the small black phono
jumpers to the middle-right side of the top circuit board. The gain can now be adjusted noting that high
gain (factory setting) is set with jumpers to the left, and low gain is set with jumpers to the right. Now reassemble your Plinius 8200.
TAPE LOCKOUT PROTECTION
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 8200 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 7.5 amp normal blow fuses.
14
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.
IMPORTANT:
DO NOT FIT A FUSE WITH A HIGHER RATING.
Note that fuse failure may indicate a severe problem. Check all speakers and speaker cables for
damage/short circuit, etc. Should the amplifier continue to demonstrate rail fuse failure, contact your
PLINIUS dealer.
MAINS/LINE FUSE
A Mains/Line fuse is fitted within the IEC socket on the rear of the amplifier. A small drawer at the bottom
of this socket may be removed (after the IEC plug is removed) by levering it out with a flat blade
screwdriver. The fuse fitted should be rated at no greater than 10 amps normal blow.
IMPORTANT:
DO NOT FIT A FUSE WITH A HIGHER RATING.
In the unusual event that this fuse should blow, you must first establish the cause of this failure (such as
power surges, damaged mains cable, etc.) before replacing the fuse with one of the same rating and type.
Should the amplifier continue to demonstrate mains fuse failure, contact your PLINIUS dealer.
15
Your Plinius 8200 Integrated Amplifier is designed for use with high fidelity loudspeakers. It should not
be used to operate 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 dealer.
