Speaker Delayed DC Protection Circuits
Usually the amplifier is shorted output transistors, DC, power failures, this situation gives reliable, though valid in the lecture but integrated requirements may vary according to the situation of failure. It makes more sense to add additional circuitry to protect the loudspeaker DC-protection circuits to detect and relay the DC output of the power amplifier disables the speaker over at. There are 3 different DC protection circuit printing circuits and schema files in the op amp and the transistor on the organizations.
