HOOKING UP SPEAKERS
(Not getting hooked up with speakers!)
It is very important that
ALL OF YOUR SPEAKERS SHOULD BE CONNECTED BEFORE STARTING THE WARP CORE (TURNING ON YOUR RECEIVER)( all new receivers have protection circuits for the amplifiers, but don't chance it)
BE SURE THE VOLUME IS TURNED TO MINIMUM BEFORE TURNING ON THE RECEIVER AND SLIPPING INTO WARP DRIVE.
Also there is usually a speaker selection menu on most receivers. Be sure to set to
off (or "none") for any channels that do not have a speaker hooked up to that channel or amplifier output.
There are two wires for each speaker and these are color coded. Hook the black terminal on the receiver up to the black terminal on the speaker. Do the same for the Red terminals. Hook one speaker and only one speaker to each output (unless you know what you are doing).
Be sure to use 12 gauge wire or larger for runs exceeding 30 to 50 feet. 10 gauge for runs of 100 feet or more. If you are running wire through a hot attic or walls, be sure to use high temperature / high volt wire stranded copper wire at your building supply store (you might need to check local building codes if you plan to run wires in the walls). Wires that carry Low voltage (speaker wire) are not required to be in conduit in most of the US and should never be in conduit with high voltage wire, unless there is a barrier wall dividing the wire tray into two sections of high volt and low volt. Check the electrical codes for your city or county to be sure, or hire a certified electrician.
PULLING WIRES THROUGH A HOT ATTIC
or how to ruin a marriage in one day!
First, you need to measure the length of the distance you need to pull wires; then add 20'. Buy a 1000' roll of 12 gauge stranded high volt wire (ohm out the whole roll before cutting it, check for continuity).
Lay out your lengths in the front yard and label then ends "one at a time". Tape the bundle together every 2 feet. Tape the ends together. Measure from a known spot on a wall and cut your access holes in the walls.
The next part is fun. Get a cell phone, flashlight, your wire, a tape measure, and a battery operated drill with a 1.5" wood bit (try to find clothes with enough pockets to do all this). Take an extra battery with you. Go up into the attic walking on the ceiling joists to the spot you need to drill, spotting the place in the attic from the landmarks inside the house(walls, vents, wires). Get on your knees and scrape the insulation away from the top plate. (I hope you wore a long sleeve shirt.)
A really good time to do this is 2PM in August. Sure!!!!
Drill the sucker. Feed the wire down the wall to another person. Drill another hole, because you are in the wrong spot. Drill a third hole because you measured from the wrong spot. Drill a 4th hole, because you did not know that the set of electrical wires you were using as a reference point run 3' horizontal in the wall after going through the top plate. Leave the attic to get a third battery or re-charge the other ones, because both of your batteries are dead. Get really pissed and get a drink. Then go back up in the attic and finish the job. Have the person on the other end take a coat hanger to snag the wire bundle in the wall. You could use a fish tape for all of this if you know how to use one safely. But be very careful around electrical wires in your walls. Know where you are drilling and cutting holes. If you are not sure, then pay an electrician to do this and be safe.
Now!! Wasn't that a piece of cake????

UNDERSTANDING OHMS
OHMS LAW+
http://communities.msn.com/TECHNOLOG...oto&PhotoID=96
A simple way to remember this is= PIE in your EAR.
Power=Amps x Volts //// Volts=Amps x Resistance
If you are deviating from a standard speaker hook up as detailed in your manual, you must be an expert in ohm calculation or have a professional speaker switching center or run a 70 volt system.
More to follow//stay tuned
All your speakers must be hooked up before turning on you receiver for the first time
CALCULATING OHMS
PARALLEL SERIES DIAGRAM FOR THE ADVANCED BORGS
http://communities.msn.com/TECHNOLOG...oto&PhotoID=98
I will start with some simple hints and end with some real meat.
First of all, I hope you bought 8 ohm speakers. Especially if that is the only speaker on that channel. Remember that ohms fluctuate widely during playback. However, a good built in speaker crossover network will keep you safe. If you use 4 ohm speakers, which some receivers allow, fluctuating ohms could easily be below 4 and even 2 ohms during playback of a signal. These momentary deviations are not a problem if the receiver is built to handle this and your built in crossover network in the speaker cabinet is a quality product. PS// Faulty speaker crossovers have been known to fry amplifiers to a well done state.
SIMPLE PARALLEL WIRING
http://communities.msn.com/TECHNOLOG...oto&PhotoID=99
Hook the wire from the positive terminal of the receiver to the positive speaker terminals of both speakers and do the same for the negative terminals. Diagrams are in the links. Two 8 ohm speakers in parallel equal 4 ohms. Two 4 ohm speakers in parallel equal 2 ohms. Just divide the ohms by two. If you use a mixture of speakers with different ohms it will get more complicated. These formulas are posted in the links.
SIMPLE SERIES WIRING
http://communities.msn.com/TECHNOLOG...oto&PhotoID=99
Hook the positive receiver terminal to the positive speaker terminal of the first speaker and then hook the negative speaker terminal of that speaker to the positive speaker terminal of another speaker. Clear as mud, right??? Do the same for the other channels. Diagrams to follow.
If you hook two 8 ohm speakers in series you have 16 ohms. Just add the ohms together to get the total ohms. Two 4 ohm speakers in series would equal 8 ohms. Different ohm speakers will require some formulas that are in the posted links.

MAKING SURE YOUR SPEAKERS ARE IN PHASE
Note: You are doing one speaker at a time/Don't get lost!
If you are not sure your speakers are in phase(all the cones moving in the same direction at the same time), then take a size "C" battery and place the negative(any) speaker wire to one battery pole and the positive(any) speaker wire to the other battery pole(note, you are doing this procedure because you have no idea which wire is which, so the negative wire comment and positive wire comment is just that a "comment". With the wires still hooked up to the speaker(use the same battery poles each time you do this or you will be hopelessly lost). The cone should move out and stay out or in and stay in until you release the wire from the battery. If the cone is moving in the wrong direction compared to the other speakers, then reverse the wires on the battery and label the wires correctly(don't change directions on the battery while you are doing this, or you are totally lost without hope). Label your wires as you do each speaker. If all the wires to all the speakers are reversed (not just one), your speakers will still be in phase. Clear as mud??????????
70 VOLT WHOLE HOUSE BACKGROUND MUSIC SYSTEMS
The 70 volt amplifier is the easiest way to get sound into a multiple room set up. Buy a 70 volt amplifier or two for stereo and a 5 to 10 watt 70 volt transformer for each speaker. A separate volume control for each speaker is an option and can be purchased with the 70 volt transformer built in.
All you need is two wires for each channel to feed the
whole house. Each speaker/transformer will drop off of the same set of wires for the whole house. Two sets for stereo. Each transformer is a mini amplifier and the wires that go to each transformer are the signal inputs and power for that speaker transformer. This is the system used in schools, and sound reinforcement applications. There is a way to balance the volume in each room without a volume control. That involves buying different watt 70 volt transformers (2,3,4,5,7,10,12,15, etc) and placing them in each room to produce the volume you want. Usually the speakers first in line will be the loudest and the ones at the end of the line are the quietest.
