If one of the AC outlets that your various components are plugged into is wired out of phase; you can experience the same result as the mis-wiring of the bass Management system and towers. An inexpensive tester such as this, can tell you if that's the case: (http://www.amazon.com/Sperry-Instruments-GFI6302-Outlet-Tester/dp/B000RUL2UU/ref=pd_sim_469_1?ie=UTF8&refRID=1GVME041151YJ24Q6J9T&dpID=51mLOd%252BDHqL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_)
Infinity IRS Betas Make Loud Noise When On
I just recently purchased some used Infinity IRS Betas. With both base towers hooked up to the crossover, the system makes a loud noise when I turn the control unit on. If I unhook the left speaker, then I don't get the noise and the sound is fine, but I hear a low hum. Same thing if I unhook the right speaker. I only hear this loud noise when both speakers are connected. I have checked, double-checked, and triple-checked my connections, and all looks correct according to the manual. Also when I disconnect the servo control unit and play them as full range speakers, they play fine. Does anybody have any idea what could be the cause of the problem?
