Just bought Technical Pro RX-400K new 2 yr warranty on eBay, 1500w 750 per channel @ 8 ohms. I plugged it in. Turned up the volume and no sound. I got a screwdriver (plastic handle) and touched one of speaker wire sticking out of the binding post and no spark. What could be wrong? I am sending it back tho, just wonder what is wrong. Oh this might no be relevent but when I plugged it in and turned it on it started smelling really weird. What is wrong?????
