Protection Circuitry - ModWright Instruments KWI 200 Owner's Manual

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
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.
