I get sound from sub, but for some reason my subwoofer get really hot and starts smoking. tried with 12v power supply and 20v the left and right channel works perfectly with both power supplies and I also tried with 2 different subwoofers. both started smoking.. I have no idea why
@@afropkerz because of the voice coil the speaker heats up so the sound becomes distorted so the speaker burns. and also because of the empedance miss matching amplifier must be 25% -50% more wattage than speakers.
Amigo, eu comprei um amplificador Zinho desse. E o sub woofer não funciona. Você conserta esse tipo de defeito? Caso você conserte, eu enviarei para você consertar.
Correct me if i'm wrong, but i don't think you'll be able to figure out the correct value of a capacitor just by comparing the printed codes on two completely different boards. These codes only indicate the position of the components and not their individual specifications, am I wrong? If anyone should have a circuit diagram of the ZKT-MT 21 board, I would be very grateful, because unfortunately I slipped with the soldering iron when unsoldering the potentiometers and killed some capacitors. 🙈 Alternatively, it would also be interesting if someone had an easier solution for me to detach or extend the pots from the board in order to build them in a different position, in my self-build case. Maybe someone already had the same idea. 😃
in fact sir you are right usually the other board does not work another smd resistor so what I do is I just increase the other value of the code or I just jumper using soldering led according to how it works. usually because the capacitor connected to the sub is always damaged, especially when it heats up. the ZK-MT21.
depending on your video board. sometimes the audio board is different. so you don't just have to replace the resistor or capacitor based on what you're just comparing.thank you.
sir sana magawan ng video kapag left and right ang walang sound
hello sir pwede po ba Jan ang dalawang 75w speaker at 100w subwoofer?
