Feb 7, 2020. #3. A protection circuit monitors the output offset voltage, and will usually disconnect the speakers if the offset voltage exceeds about 1 volt. In addition they usually monitor output transistor currents and will 'trip' if the current exceeds a safe value. Speaker Protection Circuit can be powered with AC voltage in range of 8 to 12V AC, 50 or 60Hz and requires about 40mA for proper operation. This is a very small current which can be obtained from an auxiliary winding of any transformer. $99 The Guardian-86 is a high-end protection circuit designed to protect speakers against two common ways that power amplifiers can misbehave: Sharp voltage transients on power-up and power-down, resulting in annoying clicks and pops in the speakers. A speaker protection and muting circuit is installed between a DC coupled audio power amplifier output and the speaker. Its main purpose is to disconnect the speakers as soon as a large DC voltage that can damage the speaker is present at the output of the amplifier. This can happen when the amplifier is malfunctioning.
Speaker Protection and Muting with an Optical Coupler Nuts & Volts Magazine
The speaker protection circuit detects the DC voltage at the amplifier output and disconnects the speaker. The DC voltage detection level of the protection circuit is very low (0.7…1V) so that the speaker is protected from being exposed to high voltage. with the characteristics of the speaker protection circuit; detects a DC voltage leakage which can damage speakers, the speaker disconnects the amplifier from short-circuit (overcurrent protection), overheating protection and thermostat with LED indicator present. Speaker Protection Circuit Circuit operation is simple and straightforward. To understand how it works, let's divide the circuit to 4 sections: Visual Indicator Time Delay and Relay Driver Speaker Switch DC Detector How each of these sections works is briefly described below: Speaker protection circuit engaging too early - Check if the threshold of the protection circuit is set too low or if there is a problem with the components. In case of any issues, it is recommended to consult the circuit diagram and check the connections and components. It may also be helpful to use an oscilloscope to check the signals at.

Loudspeaker DC protection is always something of a mixed bag. Units such as Project 33 are well behaved and will offer a high level of protection for the speaker. Should the amplifier fail, the most common failure mode is for an output device to short-circuit, causing the output to swing to one supply rail or the other. Speaker Protection Circuit (Stereo) This is the speaker protection circuit, provides stereo speaker protection and prevents switch-on clicks and DC components on the output of the amplifier connected.
