GOLDMUND TELOS 500 - Universal Power Amplifier - 15 

 

SAFETY FEATURES (Ctd.) 

 
 

OVERHEATING PROTECTION 

 
If for any reason (malfunction, too high level, too low load impedance) the temperature of 
the amplifier could reach a dangerous level, the TELOS 500 could be damaged. 
 
To avoid this type of damage, if the temperature rises too high, a protection circuit switches 
the amplifier OFF automatically. A red front panel light indicates that the amplifier has been 
turned OFF by the protection circuit. 
 
If this happens, let the amplifier cool for some time. We strongly recommend investigating 
the cause of the temperature gain before operating the amplifier again. 

 
PROTECTION AGAINST SHORT-CIRCUITS 

 
If one output is short-circuited by accident and the current becomes too high, the TELOS 
protection circuit may be activated. 
 
In such a case the Overload red led on front panel will turn on. 
 
First carefully check why the overload occurred and remove the cause. 
 
Then switch the power ON if the short-circuit has been detected and removed. 
 
To  avoid  Overload  occurring,  always  switch  OFF  the  amplifier  before  trying  any 
manipulation of the speaker cables. 
 
There is no risk to leave the speaker terminals unconnected when the amplifier is ON.
