Axiom Home Page Forums General Discussion Technical Questions Anoying humm in my LFR1100

Hi Matt,

Can you describe exactly what your system consists of and how you have it hooked up to the LFRs/DSP? From what you are saying it sounds as if there is a ground loop issue in the connection of the DSP to your amplifier(s). The DSP box itself is earthed, but the signal ground is floating, so it in and of itself can not cause a ground loop. However, because all 4 outputs share a common ground, there could be a grounding issue if you are using more than one amplifier to power your pair of LFRs. In that case the loop exists between the two separate amplifiers.

Thanks,

Andrew
