I have had good luck with k-comm line filters. First would try 0.001 mf line to line and line to ground - on the audio pairs - be sure you are using balanced pairs and not grounded single ended lines. This may mean adding a 600 ohm 1:1 transformer at each end. Also 1/4w 100 ohm resistors and movs make great line protection for lightning mitigation. 73, Steve NU5D
