That may be due to the difference in line level between pro equipment and consumer equipment.
Pro stuff tends to run 0 to +4 dBu and consumer stuff runs about -10 dBV. So the Pro stuff is cranking out close to +9VU when compared to consumer stuff. It might not be noticeable in a casual test, but it will turn up when things get cranking. The input stage gets overloaded.
My solution has been to build an attenuator cable.
Using 1/8W resistors, I built it into an RCA plug. All the parts can be obtained from a small electronics store like Radio Shack.
Hmmmm, for some reason the math isn't working out. I think when I went though it before, I thought the consumer stuff was referenced to 1V peak to peak. I do know the cable solved my problem of the satellite receiver distorting the audio in the VCRs.
But, if you use a 470Ώ instead of the 2.2K, then the Math looks better. But you might want to double-check those values.
