Pr
otection LED Indicator
The pr
otection cir
cuitry in the amp will disable it if it
senses an input overload, speaker short cir
cuit, or
thermal overload conditions. Should this occur
, the
PROTECT LED will be illuminated. At that time, it is important that you check to determine what has caused the pr
otection cir
cuitry to become activated.
If the amp shut of
f because of a thermal overload,
allow it to cool down befor
e
attempting to r
estart.
If the shutdown occur
ed because of an input overload,
or speaker short cir
cuit, be sur
e to corr

conditions befor
