Query: Disappointment Too

1) The system caused the rear speakers to emit an annoying hum as soon as they were turned on - this matches the report from the other reviewer, so maybe that's just how they're made. I had the SH-FX60 connected to a Panasonic SC-HT40. The rear speakers are just fine with no hum or static when connected directly.2) Within the first 5 minutes of operation, there was a small "pop!" and the rear speakers ceased to emit any sound except the hum described above. The green circle that is supposed to light up showing the receiver sees a signal also went out. Installation had been done according to the instructions. I power-cycled both the surround system and the receiver, tried taking the transmitter out and putting it back in when the surround system was off, and the rear speakers never came back on; neither did the green circle.I ended up returning the product.
