So, After owning the rack KPA for a few months (since april this year) it has developed a noise symptom.
It has lived in its rack from day one and I have only plugged it into a regular power outlet without a conditioner once over the summer.
Here is a quick description:
KPA main outs into either powered wedge monitor or into my recording interface with cable and no instrument tons and tons of noise.
Guitar or bass plugged in and every patch (low or high gain) has the noise under the tone of the instrument.
Unplugging the instrument cable from the KPA and the noise is gone.
No idea what went wrong, i thought it was my instrument cable that went bad, but i exchanged it for a new one and the problem persists.
It was never this way before. Even while switching instruments in the past, NEVER had a noise issue until now.
Any ideas?
