Help with Infinity Kappa Four

[Frycztech]

Hello,

I have an Infinity Kappa Four that both left channels play almost no audio, you can very faintly hear some audio playing. Both right channels i can get audio out of. Nothing inside the amp looks burnt. Any help on where to start would be greatly apricated.


Thank you.

Has any work been done to it?

 

[Frycztech]

Perry I do not believe so.

Have you traced the signal to see where it's being lost in the circuit?

If you don't have it:

Ok thank you. Just use a multimeter? I do not have a scope.

Thank you for the help.

Use a sine wave of about 60Hz. Set all crossovers to flat. All gains to max.

Starting at the RCA jacks, compare the signal levels through the circuit.
