20 Most Recent MTX SW2 Subwoofer Questions & Answers

There's an overload caused by a semi-conductor that is acting as if was a piece of wire. If you have an Ohm Meter and there are transistors or diodes present you can check them. They will show up on the meter as if you had touched the test probes together. If it's an IC that's gone they often have cracks or damage or even have burnt. It's harder to test IC's, but the bigger the device and any on heatsinks should be top of your suspect list. If in doubt replace it!

Try the fuse first then if no problems alls good , but if it still hums it could be the crossover board inside , if you love your sub like i love mine you will just replace the crossover if need be . Smirf 617

there is an underlying cause for the fuse to blow. if something shorts out you would rather a 40 cent peice goes then the unit causing a fire. disassembly is require... look for obvious burnt parts first.

most electronics now days only last for about five to seven years
so I would get checked out by a technician.

Check your Ariel connections for corrosion (clean them all up)
Have you relocated the unit?
Have you placed/relocated any other electrical devises near it recently??

Hello Dilum, make a test to control the sound level of the speakers connected to your harman kardon, you must press for more than two seconds the test key that is on the front panel, in the set of keys at the bottom
With the Test, you will be able to check the volume of each speaker individually, this is explained in the user manual on page 4 Item 9
If with the test, the level is fine, then you would have some problem in the recording or the program you are listening to
I hope I can solve the problem
Greetings Franco Dosil
Hola Dilum, haga una prueba para controlar el nivel se sonido de los parlantes conectados a su Harman Kardon, debe presionar por mas de dos segundos la tecla test que se encuentra en el panel frontal, en el conjunto de llaves en la parte inferior
Con el Test, va a poder chequear el volumen de cada parlante en forma individual, esto esta explicado en el manual de usuario en la pagina 4 Item 9
Si con el test, el nivel esta bien, entonces tendria algun problema en la grabacion o el programa que este escuchando
Espero pueda resolver el problema
Saludos Franco Dosil
