Axiom Home Page Forums General Discussion Stereo LFR1100 ACTIVES - WORLD CLASS SOUND QUALITY

When I first got my 'original' LFR1100 they had a humm to them. it was not the correct frequencty for a ground loop, but it turned out that my amp and the Axiom DSP were using a different method of doing the ground isolation and RCA cables just didn't want to work right. I went with XLR and the problem went away.

Disconnect the PreAmp from your DSP and see if you are still getting the noise. so you'd just have the DSP -> Amp -> Speakers and nothing else connected. This is what Andrew had me do and where we figured out the problem.
