PLINIUS KORU

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 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 100mm clearance on all sides of 
your Plinius unit to other equipment and the shelf above. 

• 

If the unit is in an enclosed cabinet, the clearance should be greater than 200mm 
on all sides. Ensure the space between the chassis and shelf below the unit is 
unobstructed at all times. 

• 

When stacking separate audio components, apply the minimum clearances above, 
as well as a minimum of 400mm clearance above the top unit for suitable airflow. 

• 

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.
