ABSOLARE Hybrid Mono Amplifier User Manual 1.2 

 

3. Unpacking and Placement 

Each monoblock Amplifier is packed in a separate box. After opening the top cover 
of each box, remove the upper layer of hard foam material. You can then lift each 
Amplifier from its box cradling them with the cloth that is underneath the chassis.  
Retain the cloth and all packing materials for future use. 

Each Hybrid Mono Amplifier may become very hot during operation. You should 
always place them on support feet and leave at least 2 inches (5 cm) clearance 
above each Amplifier to allow sufficient ventilation. 

Each Hybrid Mono Amplifier is designed to be supported by separate support feet. 
They do not have support feet fixed in place. Feet can affect the sound quality 
significantly. Feet must be positioned underneath each unit in direct contact with the 
aluminum base plate 

– not the leather clad MDF covers. There are three areas 

where the aluminum base plate is exposed through openings in the leather clad MDF 
bottom plate. You can use either three or four feet.  

After each Amplifier has been placed in its final position, it can be lifted in turn to 
locate the support feet 

– firstly lifting the back (for 2 feet) and then the front (for 1 or 

2 feet) to be placed underneath the chassis.  Adjusting their position will also affect 
the sound to varying degrees, depending on the type of rack, location or interaction 
with other equipment. For the most situations, the arrangement as shown in the 
diagram below is a good starting point.
