A majority of source components have a center of gravity that is approximately 
near  the  geometric  center  of  the  component.    However,  some  amplifiers  and 
source  components  can  have  significant  variation  in  weight  distribution  that  is 
dependent on the design layout of the heavier objects within the component. 
 
The  HRS  G7  feet  are  not  sensitive  to  component  weight  or  weight  distribution.  
You  can  use  the  HRS  G7  feet  with  any  component  weight  and  any  weight 
distribution.  For the SF/LF feet the ideal isolation base setup is to have the center 
of gravity of the component in the geometric center of the isolation base. This will 
result in even loading of the SF/LF feet. This can be achieved by estimating the 
center of gravity of your component and placing it in the geometric center of the 
isolation base. Even loading of the SF/LF feet can also be achieved by moving the 
component until the isolation base is level.

Component and Isolation Base 

 

If you have a component that does not allow you to locate the center of gravity 
near the geometric center of the isolation base with SF/LF feet, you can utilize a 
custom  combination  of  isolation  feet  to  accommodate  a  significant  variation  in 
isolator loading. Please consult with your authorized HRS retailer or HRS directly 
if  you  have  questions  regarding  proper  loading  of  your  R3X  Isolation  Base.  
Custom HRS Isolation Bases built for a specific component model have already 
been set up for that specific component weight distribution.  If the component is 
centered on the custom isolation base and the HRS logo is in the right front corner 
then the loading of a custom base model is correct.
