I've heard the rumors when we had a security camera installed in our offices a while back about how I shouldnt let the video cables from the monitor ever criss cross the power ones. Fast forward a week back.. Just purchased and hooked up an Onkyo HT-S7300 system with 16 gauge wires. As we all know .. ridiculous amounts of wiring and cables behind it. The manual did briefly specify to avoid contact between the cables. Is this something i really NEED to worry about, or is it just a precaution that got blown out of proportion? I can't imagine controlling all that wiring in such a tight space. Any thoughts/input?
