The amplifier protect ion circui try will disabl e the amplifier if the inpu ts are overl oade d, short -circui ted or
extr emely high tem perat ure cond itions are detect ed. When the protect ion mod e is in op erat ion, the LE D indi cat or
on the front panel will be illum inated, indi cat ing the am pl ifier has gone into a sel f-pr eservat ion mode.
