I have a 12 channel amp powering 6 pairs of speakers along with 6 impedance matching volume controls throughout the house. When I connect one particular pair of speakers they are distorted and only play at a very low volume. If I put my ear to the amp I can hear a distorted audio signal which is alarming because the amp doesn't have any internal speakers to be outputing any sound. I get the same result no matter which channel I connect this particular set of speakers to so it must have something to do with the wiring for these speakers. All the other speakers sound fine.
Would this be a short in the wiring??? Or something else????
