Positioning 

In order to protect against the risks of fire and electric shock, please keep this 
device away from rain and humidity, use exclusively indoors. 

 
The Nagra MPS must rest on a stable support. We recommend that you use the 
anti-vibration support, Nagra VFS, Vibration Free Support, developed by Nagra 
consisting of isolated solid aluminum plates using the same silicon base damping 
material as the Nagra CD mechanics. Please note that the MPS needs four spikes 
and thus is not compatible with older VFS (before 2012). Feel free to contact your 
Nagra dealer for more information. 
 
it is not advised to place other Nagra units above or below the MPS, as it features 

a large transformer. It is preferable to use a separate shelf for other devices.
