According to the book "G. Randy Slone: High-Power Audio Amplifier Construction Manual", the current limit protection is utilized inside of VA stage of …
The Problem with Current Limit - Power Amp Design
http://www.powerampdesign.net/images/AN-12_The_Problem_with_Current_Limit.pdf
One technique that helps protect the amplifier is dual slope current limit (fold-over current limit). As the voltage across the output transistor increases beyond some point the current limit value is reduced, thus helping the amplifier survive over-current conditions. See Figure 4. - 4 -
Audio Amp Power Limiter
https://sound-au.com/project53.htm
It is vitally important that the (limited) amplifier power is within the maximum continuous power rating of your speakers. As the input level is increased, the average power also increases. A 500W amplifier will cheerfully destroy 500W (peak) speakers, even if the amplifier never clips.
An Op-Amp Limiter: How to Limit the Amplitude of Amplified ...

As expected, then, the limiter is just a normal amplifier as long as the output is not high or low enough to provoke its limiting functionality. As the output increases, though, the voltage at the anode of D2 starts to increase relative to …
LM317 as current limiter for audio amplifier | Electronics ...
https://www.electro-tech-online.com/threads/lm317-as-current-limiter-for-audio-amplifier.125739/
Hi, I was planning to use LM317 as a current limiter to a transistorized audio amplifier that would limit the current to 500mA.It is understood that the current would be limited by adjusting the output voltage i.e. drop more or less voltage across the LM317 to …
