Transistor protection circuit for the amp speaker I’ve shared before, “and led Delayed-Exciting DC Speaker protection circuit” The advanced form of the application is different.
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
-R and L in the transistor amplifier + pro places the supply line from the output resistance of emitter end before the tr must be connected. Amfide how many en have, in parallel. So in this State, the 2 + 2 trli amplifier.
-Res resistors 12v relay to exceed level should be selected by evaluating the 12v to u,
-Circuit feed if the separate power supply gnd in line if amp should be taken from those stars gnd.
-Metal boxes from the screw to pad gnd connection to ‘ ‘ place the Earth near the land behind the icon with led cable can use by making the jump.
-Therm A, normally conductive (i.e. cold) 60-70 degrees optional thermostat. To select which is the short circuit should be done.

High-quality low-cost amplifier 20W
The operation of a transistor amplifier for beginners. Integrated transistor amplifier from a mediocre competitors an example of how cheap it is superior, actually.
I found a diagram in a foreign forum, I wanted to introduce a quite simple and low cost circuit.

Komplette Lautsprecher-Schutzschaltung
Transistor-Schutzschaltung für den amp Lautsprecher die ich geteilt haben, bevor, “und die led Verzögert-Spannend DC Lautsprecher-Schutzschaltung” Die erweiterte form der Anwendung ist anders.
mit den Eigenschaften der Lautsprecher-Schutzschaltung; erkennt eine DC-Spannung Leckage kann zur Beschädigung der Lautsprecher, die Lautsprecher trennt den Verstärker vor Kurzschluss-(überstrom-Schutz), überhitzungsschutz und thermostat mit LED-Anzeige vorhanden.
