Protection of speakers

High-quality low-frequency chain is relatively very expensive and thus no wonder that they are trying to protect its individual components in every possible way against damage or even destruction of improper manipulation or random problems. One of the possible failures are punctures one of the terminal transistors power amplifiers or any other cause, leading to nesymetrii output. As regards the power amplifier is symmetrical, which normally has a capacity of separate speakers, the speaker or speakers safely leave their existence, as a result of a DC congestion. In these cases it is intended, this structure, which responds to the presence of the DC voltage output that disconnects speakers As a practical application requires intervention in amplifiers, not circuit, despite its simplicity and primitivism, designed for complete beginners.
