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 of ten 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

This Plinius product may operate at a moderately high temperature, especially during

extended listening sessions. With this in mind, we recommend the following guidelines

for placement and ventilation:

• 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 be kept unimpeded.

• Ensure heat vents (slots in the base and lid) are not covered or restricted in any way.

• Equipment racks should be of an open type with no closed side panels and no

closed front or rear panels.

• Ensure a minimum of 400mm clearance on all sides of your Plinius unit to other

equipment and the shelf above. Ensure the space between the chassis and shelf

below the unit is unobstructed at all times.

• DO NOT place this unit in an enclosed cabinet.

• DO NOT stack other audio components on top of this unit.

• NOTE: This unit has been designed for use in moderate climates only, not for tropical

conditions.

The design of this Plinius product 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.
