They recommended a 1:1 audio isolator when I spoke with them shortly after I
got mine. A lot of
people have had problems with ground loops.
That's on my wish list of things they should have done. Along with not using
RCA jacks on the
accessory cable. It could have just been a 1/8" stereo phone jack, so we could
just use normal
cables.
That's not to say that some enterprising person couldn't put together an after
market accessory
cable, with the isolator, and the stereo jack.
