Overheating protection circuit
The Performer s1200 is actively cooled with six temperature controlled fans that usually do nothing at all,
because 90 % of the heat is passively dissipated via massive heat sinks. Should it nevertheless become really
loud for a really long time, the processor-controlled fans remain virtually inaudible at only 19 dB (A).
In the unlikely event of overheating the Performer s1200 will switch off at about 70° C at the heat sink and the
on the front indicates the overheating.
After the temperature has fallen below 55° C, the amplifier automatically switches on again.
