ModWright Instruments KWI 200 Owner's Manual - Protection Circuitry:

3 

Protection Circuitry:

  Protection Circuitry: 

This amplifier has multiple levels of circuit protection, designed to prevent damage to 

amplifiers, speakers and connected equipment.

o  DC input protection provided by transformer input coupling. 

o  Thermal overload protection provided by internal thermal sensors.  Upon 

thermal overload, amp will simply shut down.  The message “00” “P5” (“OOPS”)   

will be visible on displays and will go out after 8 seconds. If this happens, let amp 

cool and then turn back on. 

o  DC Output Protection provided by our unique and proprietary TSP

TM

 “Total 

Silent Protection” circuitry, residing entirely outside the signal path.  When 

protection is triggered, the amp shuts down and the message “00” “P5” (“OOPS”)   

will be visible on displays. Message will remain for approximately 8 seconds.  If 

amp continues to encounter this fault condition, and will not turn on, contact 

dealer or ModWright service agent. 

  Fuses: 

o  All fuses are internal and are only to be replaced at the factory or by factory 

authorized technician.  There are no user serviceable parts inside and opening 

the unit will void the factory warranty. If unit protection triggers and amp will not 

re-start, please contact factory or ModWright service agent.
