    Hi All

    I have an issue with my amp. The LHS does not work. It’s not the bass transducer as I have plugged the other amp (2 amps running 4 shakers) into the front and both work.

    It’s a 100w x2 TPA3116 chip.

    So what am I searching for in order to see if I can fix it ??

    TIA

    How is the amp configured?

    Does the amp work with a simple speaker?

    You would think with such a simple question that the answer could be obtained easily. I had to go and borrow speakers that have wires ... then the wire I had was way too big ass for these little speakers .. hahaha. But putting it together brought back memories :p

    So the answer was no ... still only the LHS worked. The RHS had this weird pulse beat to it ... like a faint bass. This was also an issue with the transducers .. but obviously more prominent with the transducers as you could feel each pulse but with the normal speaker it was more like tapping.

    I think it likely the amp is faulty on the RHS channel, as long as there is nothing wrong with computer sound configuration.
