How do I run low voltage wires and a receptacle wire from my TV upstairs to the basement below where the components will be? I have plaster that is attached directly to brick (no wood lathe or anything) and somehow drywall is glued and nailed on top of that. That leaves me on average a heavy inch from the face of the brick to the finished surface. My plan is to channel out the drywall/plaster on one side and run low voltage wire (speaker wire, hdmi, etc.) in some sort of raceway (wiremold?) and then refinish the wall with plaster so the wiring is completely hidden. I'd also like to do the same thing on the other side of the TV (about 3 ft away) except it'd be 12 gauge wire to a receptacle. The wires would be nearly flush to the face of the drywall and y understanding is that if my wires don't START at least an inch deep into the brick than I need intermediate metal conduit or rigid metal conduit which is ok for the power side but won't this cause EMI on the low voltage side with all my hdmi, toslink, etc.? What can I use so that both sides are nail proof/nail resistant? Would a metallic raceway cause any induction or interference? Would running a lot of theater wires together cause interference? Would this be up to code? I've been looking at the NEC code book and have somewhat of a handle on what is necessary in terms of future nail/ screw proofing, but I am worried about EMI.
