DESIGN PHILOSOPHY
From a distance you can see that the design of the Plinius products is more than an applied styling
exercise to the front panel. We have started from the ground up to produce a casing for our electronics
that is unrivalled in its physical strength and visual simplicity. Wherever possible we have reduced the
number of parts needed and then invested massively in refining and producing the remaining parts to the
highest quality achievable with state of the art computer controlled machines allied with expert craftsman.
Examples of this approach include the hydraulically formed corners on the amplifiers giving much greater
strength and the one piece housing for the remote control unit that eliminates large joints and potential
creaks.
The very process of holding the remote tells you that you are controlling both a powerful and precise
product. It is designed specifically for the act of listening to music, not channel surfing on a television or
changing the room temperature. The distinction is important because we believe that listening to music is
a highly selective and emotional experience that requires a much greater level of concentration and
precision to fully appreciate and enjoy.
As with music that you are not familiar with, truly innovative new designs can take time to understand and
enjoy. How often have you heard music that you were first unsure of, that over repeated listening, has
become a firm favourite. Our designs are fundamentally different to many other companies, and we hope
that you will take the time to explore their unique character and qualities because we have not made them
different simply to be different. We genuinely believe that their visual and tactile qualities do improve the
experience of listening to music and that is our design goal!

PRECAUTIONS
Please take special note of the following precautions before operating your new amplifier:
• The Plinius 9200 Integrated Amplifier can deliver in excess of 200 watts into 8 ohms. This
amplifier is also capable of a very large peak current delivery.
• The Plinius 9200 Integrated Amplifier operates in Class AB. It is capable of generating heat that
could have an adverse effect on other electronic equipment, furniture, etc. DO NOT leave
flammable material on the amplifier whilst running, as this could pose a serious fire risk.
• This amplifier operates at hazardous voltage levels. There are some alterations that may be made
by you, the owner. However, we recommend that any work requiring removal of the lid be referred
to a suitably qualified and experienced service technician.
• DO NOT attempt to connect any input of this amplifier to its own outputs.
• DO NOT earth any output terminal or connect any of these terminals together without following the
instructions in this manual or seeking qualified assistance.
• DO NOT place this amplifier in any position where liquids, or any foreign material may accidentally
enter it.
• DO NOT connect any voltage source, short circuit, earth/ground or appliance (other than suitable
high fidelity loudspeakers) to the amplifier output terminals.

AMPLIFIER FEATURES – FRONT PANEL
The front of the Plinius 9200 Integrated Amplifier incorporates all the facilities
you will require on a daily basis.
FRONT PANEL LAYOUT SHOWING VOLUME KNOB, RECORD
AND SOURCE SELECTORS, AND DISPLAY LED
DISPLAY LED
An LED on the front panel indicates that the power is on. When first switched on, the display LED will
pulse for ten seconds - this is an initialisation sequence, after which the LED remains lit during the time
the amplifier is powered on. Whenever mute or a remote button is pressed, the LED will dim.
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.
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 9200. The knob can be adjusted manually or with the remote control
supplied. When using the remote control to alter the volume level, briefly press the button to make small
adjustments, or hold the button down to continuously adjust the volume.

AMPLIFIER FEATURES – REAR PANEL
This panel incorporates all 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 9200 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, MAINS SWITCH AND MAINS SOCKET.
MAINS SWITCH
The heavy-duty rocker switch in the centre of the panel turns the Mains/Line Power to the amplifier ON or
OFF. 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.
INPUT TERMINALS
The input terminals for your Plinius 9200 Integrated Amplifier are easily accessible along the top of the
rear panel, with the right (red) inputs along the top. The five sets of 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.

CD XLR INPUT TERMINALS
Below the CD RCA inputs are an additional set of ‘line level’ XLR balanced inputs for use with source
components that feature XLR balanced outputs. Balanced signals are carried via a three way cable.
The XLR pin configuration used in all Plinius product is:
PIN 1 to GND
PIN 2 to +Signal
PIN 3 to -Signal
NOTE: Because of the way our XLR and balanced inputs are configured it is not possible to connect both
XLR and RCA at the same time.
INPUT SELECTION SWITCH
This switch directly below the ‘TAPE 1’ input is used to select the pair of CD input sockets required as
described above. Up selects the CD RCA input connections, while down selects CD XLR input.
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.
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 front panel will dim.

9
GROUND LIFT SWITCH
This switch allows the signal ground to be disconnected from the chassis. In some installations a hum
loop may exist due to duplicate ground paths from different equipment. Use this switch to remove the
connection from 0V to ground thus allowing some flexibility in your particular set-up.
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 9200 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 9200 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 9200.
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 anti-
clockwise 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 most vinyl turntables.

INSTALLATION AND OPERATION
PLACEMENT AND VENTILATION
Your Plinius 9200 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 9200 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).
