FAQ:
Q: What is speaker DC protection with relay?
A: Speaker DC protection with relays. Introduction. An important feature of an audio amplifier is to provide a system to protect your speakers in case the amplifier breaks down and puts DC on the speaker terminals.
Q: How do I protect my speaker from power amplifier?
A: You should use a speaker protection circuit. To keep your speaker expensive! Sometimes your power amplifier may kill your speaker by accident. This circuit is simple, small and inexpensive. The main parts are the transistor and relay to cut off the power. You can make it in a short time with pcb layout.
Q: What is the purpose of a speaker protection system?
A: Introduction An important feature of an audio amplifier is to provide a system to protect your speakers in case the amplifier breaks down and puts DC on the speaker terminals. No speaker will take kindly to the presence of 50V on its voice coil, so that has to be prevented.
Q: Is the speaker protector Circuit good or bad?
A: The speaker protector circuit is good. It should have those functions. First of all, both resistors R1 and R2 reduce some lower signals from the speaker. After that, the capacitor, C1 serves to bypass this signal to the ground. However, if the power amplifier works error.
