Thermal Protection All amplifiers produce heat The TH 12A is designed to be efficient both electrically and thermally The amplifier module is mounted on a large heatsink which is cooled by convection where cool air is drawn over the rear panel carrying the heat away In order for this convection cooling to work efficiently it is important to provide adequate airspace behind the loudspeaker When you position the TH 12A we recommend leaving at least six inches of air space behind it e Iffor some reason the internal temperature gets too hot a built in thermal switch activates and turns off the amplifier This protection operates independently for the low frequency and high frequency amplifiers Therefore it is possible for only the low frequency or high frequency amplifier to shut down while the other remains on e When the amplifier cools down to a safe temperature the thermal switch resets and normal operation resumes 10 e Ifthe internal temperature again gets too hot the shutdown process repeats Should this happen make sure that airflow to the rear of the cabinet is not restricted If the ambient air temperature is very warm try pointing a small fan toward the rear panel to increase the airflow across the rear panel Driver Protection Each driver has its own compression circuit which helps protect them from damaging transient peaks The compressors are designed to be transparent and are not noticeable unde
