Introduction
Congratulations on your decision to become the proud owner of this
Plinius Hautonga Integrated Amplifier.
This manual has been prepared to help you understand the operation of your amplifier,
and to provide information about its design and the variety of ways it may be used.
We have designed and manufactured this amplifier to reproduce your favourite music
faithfully and accurately. With a little care and a full understanding of the operating
recommendations in this manual, your Plinius Hautonga Integrated Amplifier will
provide years of high-quality, trouble-free performance.
Please take the time to read this manual thoroughly before using your amplifier.

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 that looks, feels and genuinely is robust.
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!

Unpacking
Open the box from the top and remove the accessories from the foam end caps.
You may now proceed to lift the unit from the box, Once the unit is removed you can
proceed with the removal of the foam end caps. These caps are designed to fit on
the front and back of the unit for maximum protection. Retain the packaging for future
transportation of this unit.
Placement & Ventilation
Your Hautonga Integrated Amplifier may operate at a moderately high temperature,
especially during extended listening sessions. The ideal location is upon a rigid
stand, away from direct contact with any temperature sensitive materials, furniture or
deep pile carpets. Ventilation through and around the amplifier should also be kept
unimpeded. Please ensure that the heat vents (slots in the base and lid) are not
covered or restricted in any way.
The Hautonga Integrated Amplifier design incorporates a very high level of
mechanical decoupling 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.

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
Exposed connectors such as the RCA connectors will be subject to environmental
factors, and over time the surface may degrade. This can be greatly reduced by fitting
readily available ‘RCA caps’ to reduce the effects of environmental elements on the RCA
connectors. These RCA caps or RCA shorting caps can also provide sonic benefits.
Connector cleaning products are also available to clean the RCA and cable connectors
and frequent checks and cleaning will help maintain a good signal connection.
NOTE: DO NOT use RCA shorting caps on output connectors or power amplifier input
connectors. Use RCA shorting caps on unused preamplifier stage input connectors only.
Standard RCA shielding 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. Per forming 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 finish 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:
As a safety precaution, always switch the equipment off prior to cleaning
Always use a cloth that is soft and clean
Never use abrasives or polishing compounds anywhere on the unit
Never apply liquid directly to the surface of the unit
Use the cloth dry or with mild surface cleaners of either liquid or foaming type
Apply only small amounts of cleaner to the cloth
DO NOT rub the surface but wipe clean only. Excessive rubbing may dull powder
coat or wear the screen printed text.

Precautions
PLEASE TAKE SPECIAL NOTE OF THE FOLLOWING PRECAUTIONS
BEFORE OPERATING YOUR NEW AMPLIFIER.
The Plinius Hautonga 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 Hautonga 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.
