Installation & Placement   

 

The 

Lab12 suara

 should be placed on a solid, flat surface.  

You  should  avoid placing  it  near  a  heat  source as  this  could  compromise  the  suara

s  performance  and 

reliability.  

Carefully put the tubes in dedicated sockets. Make sure that tubes are perfectly snap into sockets. See 
bellow page. 

Due  to  high  power  tubes  design,  suara

s  chassis  could  be  hot  so  you  should  never  place  another  hot 

component directly near this device

.  Make sure that the device has enough space to ventilate. 

Tubes will be hot, this is normal. Be careful not to touch the tubes during the operation to avoid any 
injuries.  

Take care of the finest luxury finish of front panel with a soft cloth.
