OK, I'll admit I'm a bit of a novice but I'd like to think I'm not a total moron.
I have an Onkyo TX-SR674 receiver and I hooked up the Zone 2 speakers to a Phoenix Gold ISM-8 speaker selector so I could route sound to various speakers throughout my house. I turned on the receiver, routed a CD to Zone 2 and turned on two speakers. I turned up the volume on Zone 2 fairly high. Within a few minutes my speaker selector got very hot and starting smoking. Smoke was heavily rolling out of the speaker selector and I could smell burnt plastic.
Laugh all you want but someone tell me what I did wrong. The speaker selector says it can handle 140 Watts RMS/Channel. My receiver is 95 Watts/Channel so I just assumed the speaker selector could easily handle it.
