200W amplifier


I have just finished and tested the 200w amp with an 8ohm speaker, the speaker has suitable RMS etc for the amp but it literally burnt out (smoke) as soon as I tested so I immediately turned it off…

What are the most likely problems for this to occur? I have tested polarity, I can only think that there is a problem with the ground as I did not connect the ground for testing.

I used a microphone input with no volume control so would the input have been too great?

Thanks, Fabian.

Please check the numerous posts on this item.
Btw: the unit is equipped with a line input, not a microphone input.


They are not relevant… I have read them all.

The microphone was the input, not part of the kit…

If the numerous posts on this item do not help, then we suggest that you return the amp for inspection/repair.
