I should add to my previous post that when I say I recieved a very low signal I mean the amplitude is very low and there is a significant lack of low frequeinces.
I also tried using an XLR cable with an old XLR to 1/4 adapter and from there went to a 1/8 adapter. The result was a strong signal with all frequencies present (alas, sound was only present in one channel).
This is the XLR adapter that I used in this test.
Why did the Radioshack XLR adapter combined with the additional 1/8 adapter produce near sufficient results and the original XLR to 1/8 cable detriment the signal?
