Advice on pre-wiring home theater/audio in a new house
Hi,
I am in the early stages of having a house built, and I have some questions about wiring for the audio stuff. I will not have a dedicated audio room, rather this will be in the great room (about 19' x 22' with 12' ceilings). I will be using a Yamaha RX-V1 receiver set up for 6.1, klipsch RF-3II mains and Klipsch surrounds, and center channels (both front and rear). I am planning on running 14/2 CL-3 speaker cables in the walls, (in addition, I am running a cable to allow for 7.1 in the future). As is stands now, I plan on running the speaker wire my-self after the power wires have been completed. (taking the usual precautions not to share holes in the studs, using seperate conduit, etc) My main question is should I have the electical sub-contractor run a dedicated 20 amp circut from the box to the outlet where the components will be pluged in? Should that circut be grounded seperatly? Is there anything else I should consider? If I am thinking about Hi-def TV, what pre-wiring will I need to do, or can the Hi-def signal come through the coax cable? Thanks in advance, Jay |

I dont know if you are watching your thread , since you posted almost 3 weeks ago, but I just noticed it and thought of a couple of suggestions that might help. 1) about a dedicated 20 amp circuit: it definattly could help, I ran one to my main rack mount in my entertainment room and installed quad (four recepticals instead of the std. two) you can never have to many recepticals. also be sure your electrician uses high quality 120 or 125 volt recepticals, (I use hospital quality) they are pricy but worth it. your electrician might not be willing to run a seperate ground as this could violate local codes, Not to mention the NEC. however what I am in the process of doing myself is putting together a truly isolated circuit by using a small 3KVA transformer to isolate and power the circuit. I am using a Sq D 220/120 Pri. by 220/120 Sec. general service transformer with a grounded core that I bought new off of EBay for $80.00 I will power it from a 220 two pole breaker (15 amp if I can find one) and run the secondary to its own small sub panel. The secondary is rated at 25 amps @ 120 volts and I will size the breaker at a conservative 20 amps. I also have the ability to ground the core which should help clean up the secondary power. a big advantage of this setup is isolation from the rest of the house when their are various inductive spikes (air condition, refrigerator, freezer motors etc.) it also gives some protection from major power spikes from the outside (lightning strikes, power surges,etc). 2)pre- wireing: one of the neatest tricks I have heard of was in home video magazine a couple of years ago, a installer would go into homes during construction and before drywall and determine any and all places that stereo, audio might go now and in the future and he ran PVC tubing through the walls to those points, and interconnected it all. the benifit was that he could wire his audio/video system now but in a few years you might want to add on something new or install somewhere you hadnt allready, and if you have ever wanted to run new cabling after the house is finished you know it can be a tremendous headache. with the PVC (of a reasonable size) already run it is pretty easy to fish what ever new cable you need through the walls when needed. 3) invest in good quality wall plug ins. I have all of my speakers and my remote room interconnects terminated at wall plate plug ins. including a patch panel at the main rack, its super clean and very easy to make connections (New and Old) everything becomes quick disconnect and looks professional 4) do not skimp on a power conditioner surge protector!! if you have any investment , or might in the future then forget the radio shack specials. Monster makes some "OK" cheap conditioner/protectors and they should be considered a minimum. You can spend thousands on these things but thats up to you, I have about $15000 invested in my system (very in exspensive) including Television, and I am using a Monster protector that costs about 150.00. I would like a better one but am reasonably satisfied with this one as long as I have my isolated power. Hope you find this and that it helps, good luck and remember you can never have to good a home entertainment system, protection looks real cheap after a lighting strike blows the power line transformer off the pole outside your house.
