THERMAL CONDITIONS 
           

The ISP 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 is exposed in the front port of the cabinet. Airflow is forced through the fins via 
the air pressure from the speaker. It is recommended that the fins have at least 6 inches of 
clearance from any obstruction to allow proper ventilation to occur.  
  
In addition the amplifiers are thermally protected internally via a thermal switch, which will 
attenuate the signal 40db when the temperature exceeds a certain 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).  
 
Under extreme conditions, such as when ambient temperatures are too high (hot rooms, 
extreme outdoor temperatures) it is recommended to use a fan on the fins to reduce the 
cycling affects.
