THERMAL CONDITIONS 

           

The ISP XMAX112 Sub Series is capable of producing 1000 watts at full power.  This generates 
heat that must be dissipated in order to maintain reliability and insure the amplifier components 
stay within their operating temperature specs.  To accomplish this, the amplifier is mounted onto 
a heatsink that requires air movement at the rear of the cabinet.  It is recommended that the rear 
of the cabinet have at least 6 inches of clearance from any obstruction to allow proper ventilation 
to occur.  
  
The  internal  amplifier  is  cooled  with  a  small  fan.    The  XMAX112  is  designed  such  that  the 
temperature should never exceed a level where the global thermal protection becomes active.  If 
the  internal  fan  fails  or  the  ventilation  system  is  blocked  so  that  airflow  is  impeded  the  global 
thermal  protect  may  activate,  which  will  attenuate  the  signal  40db  when  the  temperature 
exceeds  a  preset  point.    When  the  temperature  drops  below  a  certain  point,  full  signal  will  be 
restored.    Tests  have  shown  under  extreme  conditions  that  cycling  will  occur  (40  sec.  ON,  20 
sec. OFF).  If the global thermal protection becomes active, determine the cause for the lack of 
proper cooling.  Correcting the problem will allow the XMAX112 to continue correct operation.
