My guess is that it is an impedance problem. I get horrible 60hz humm if I  
hookup a headset mike that has a line transformer and put the high/low  
impedance switch in the wrong position. This is with a new monitor.

I've also notice that the external mike input on the old and new monitors  
are different. A mike that works on an old monitor may not work good on a  
new monitor.
