Re: amp - long cable - speaker = hum/noise?

[Bob Weigel <sounddoctorin@imt.net>]

HEhe..Yeah unless you are dealing with a powered speaker here as is 
often the case these days..then the long cable especially if not good 
quality would come into play maybe.  Many of these have balanced cable 
inputs and if people use an adapter on one end and imbalance it that way 
of course that will lessen noise immunity. 

If it's *really* a speaker cable though, and a non-powered speaker it's 
hooked to..simply unhook the amp from the cable and let the cable hang 
in the air.  Do you still hear the hoise?  If so..you are probably in an 
environment which is causing you bodily damage.  RUN!  :-) -Bob
