Thoughts: Seems sound and straight-forward. The whole point of the tip is to spare the need to pull wire/cable through the wall. Another take might be that Cat4, or Cat5, would be easier and cheaper to pull even if there wasn't an existing jack where you needed. I did a run of Cat5 from the study where my computers and some audio equipment is located, and also where my FiOS wireless router is, up to the attic, along the floor boards, and down into the back bedroom, terminated on each end by RJ45s and wall plates. I also pulled up from the basement a Cat4 phone line and a romex power line from at dedicated and well-grounded GFI breaker through the same stud box as the coax for the router, installing a nice 4-outlet receptacle box to power up my computing gear and accessories. Sorry about the generally irrelevant details, but my point is that pulling or dropping wire up and down between the studs of a typical frame house, especially with an attic and basement. So, I wouldn't shy away from going after just the cabling and outlets you need for convenience and productivity. As far as the baluns go that are specified in this article, their purpose is to match the impedance of the balanced (bal) Cat4 running through the walls with the unbalanced (un) coaxial cable running to the audio equipment in the room. What I meant by my cable-pulling suggestion above is that this is still a valid solution even if you're starting out from scratch into that room. Multi-conductor Cat4 or Cat5 cable would give you telephone and audio and even Ethernet if desired. It's cheap, light, easy to pull and terminate, and versatile. I'd certainly choose to run that over dedicated coaxial cable from the audio source. Then, while you're at it, if you wind up pulling your own wires, you could add - or have an electrician add - some power outlets too, for just a couple bucks. My 1926-construction house really appreciated the extra 3-wire outlets. Frank p.s. Without those baluns, you'd be humming a sixty Hertz tune, fer sure... _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
