I am planning on doing in-wall wire of a house I'm building.
I am going to run wire from my stereo location (future) with binding posts to volume controls in the rooms I am interested in having sound. I plan on initially using a speaker selector connecting to the binding post on the wall behind the entertainment center. My questions a 1) How many Watts do my volume controls need to support (practically, not theoretically)? 2) Do I need impedance control when using a speaker selector? 3) Do I need impedance control when using a 12-channel amp? 4) Any good sites that describe how to set up a parallel of mono- speakers? I want a few zones of just ambience music (hallways and such). Thanks for all helpful replies! |

1) It depends on how much power you will be using, loud, moderate or
soft listening level. Too small a control might burn up if too much power is sent through it. It will hurt nothing to send a small amount of power through a high power rated control. 50 Watts would be reasonable, unless you plan to rattle the windows. 2) An impedance compensating control is not a bad idea, it will present a consistant load to the amplifier. 3) If you are doing all your level control at the amp with each channel feeding only one speaker, you would not need impedance controls. If you are planning on using remote speaker level controls, in the speaker lines, you should use impedance controls. 4) The impedance seen by the amplifier will decrease every time you add a speaker. Using speakers of equal impedance, divide the impedance of one speaker by the total number of speakers connected in parallel: 1) 8 ohm speaker = 8 ohms, 2) 8 ohm speakers = 4 ohms, 3) 8 ohm speakers = 2.66 ohms, 4) 8 ohm speakers = 2 ohms. Do not use a combination which will result in a load impedance lower than the rated output impedance of the amplifier (Read the spec. in the amp. manual). I hope this helps Lee Salter |

if using umbilical
cords so they won?t be tough). Place a slice of ham and cheese on each, along with some minced onion then fold in half, trimming neatly. Dredge in flour, eggwash, then seasoned breadcrumbs; allow to sit for a few minutes. Sauté in butter and olive oil until golden brown, about 6 minutes on each side. Shish Kababes As old as the hills, this technique has employed seafood, beef, pork, lamb, poultry, and vegetables; just about anything can be grilled, and young humans are no exception! High quality marinade (Teriyaki and garlic perhaps) 1 inch cubes of tender meat, preferably from the nursery Onions bell peppers Wooden or metal skewers Marinate the meat overnight. Get the grill good and hot while placing meat, vegetables, and fruit such as pineapples or cherries on the skewers. Don?t be afraid to use a variety of meats. Grill to medium rare, serve with garlic cous-cous and sautéed asparagus. Coffee and sherbet for desert then walnuts, cheese, and port. Cigars for the gentlemen (and ladies if they so desire)!
