Post Subject: I think you have a HF loop…Posted by Romy the Cat on: 4/22/2009

Jp,

I think what you do is wrong. The ferrites that you use on the picture are worthless as they will not be having much coupling between the cable and ferrite cores. You need to block entry to Sansui for HF noise. The noise might enter via power cables, antenna, air and interconnects. You need to isolate and debug each case. The most important is that you need to found out if it is the problem with loop (most likely it is) or with just AD122. If you claim that as long as an analog interconnect is connected to the AD122 it creates noise then will the noise be there is you unplug the digital cable to DA924. I bet that will go away that means that it was a loop. If you do not resolve it with a PROPER protecting ALL Sansui cable from HF noise then you can always unplug the DA924 what you do recordings.

Rgs, Romy
