What is afailed earth loop imperdance and how can i fix the problem.

This sounds like an earth loop, try discounting the earth in the record deck 13 amp plug. If this works reconnect earth and get a stereo isolating transformer to go between the output of the record deck and Kenwood amp. Remember disconnecting the earth can be dangerous if you don't know what you are doing, best to just disconnect the RCA leads from the deck to start with. To explain an earth loop it's when you have more than one earth point e.g. amp with a earth and record deck with a earth or a CD deck. You can get the transformer from marlin.

If your tv uses rca a jacks to connect it up to the reciever, You coul try what is called a ground loop iceilator, It hooks up to the patch cord,If they are still availible.They were use on car Stereo,s when you have a amp hook up to it,In some vehicles you would get a ground loop hum. Radio Shack might still sell them. You could try one.It work for me with a (Carver) Power amp that i use to own.

The humming noise could be a earth loop problem.
This is caused by having the speakers/sub woofer connected to one power point and the computer connected to a different power point.
To eliminate earth loop problems, connect both the speakers/sub woofer and computer to only one power point. Connect all your equipment to one power point using a power board.

hi, i presume you mean earth, (neg) when you say ground. if this is the case have you tried looping the earth from the main beam side of the light, and afix it to the bulb holder on the low beam, is it that the unit is corroded around the earthing point, if this is the case you could simply fix a wire to the bulb retaining spring and see if the light works, this will be fine and work until you find areplacment light unit, make sure the earth wire canot come into contact with the live side by insulating it, hope this helps, paul

It sounds like you are describing an earth loop problem. I won't go into detail in this post, but try an isolation test first. disconnect everything from the reciever except the sub and try connecting say a BATTERY powered mp3 player or cd player to minimise connections to the electrical mains earth. you could also isolate things by taking your sub to a friend's house and trying it on their system.
If it is an earth loop use a process of elimination to find out which two pieces of equipment causes the earth loop. then apply filtering.
you can buy earth loop isolation transformers for about AU$26 and I've used one on my sub myself. Theyhave RCA (phono)plugs on each end and they connect inline with the signal cable to the sub amp.

as for the thumping sound it might be the speaker protection circuitry cutting off the amp to protect the subwoofer speaker from damaged. This might be triggered if the earth loop sound is causing the sub amp to overload and clip.

Failing this there might be a dried out overheated electro capacitor in the amp circuit causing the hum. Hav a chat to your local electronics person, who should be able to spot it!
Hope this puts you on the right track
Happy Hunting!

Hi
Probably put your family at risk of electricution . By connecting the live cables to earth you have effectivly made all the metal light fittings live. It is amazing that the fuse has not blown, This in itself is dangerous and you should have an electrician look at the wiring.
The correct wiring should be as follows.
Identify cables there should be 2 twin and earth (red black & copper earth) cables and 1 twin red and copper earth. (or 2 single red wires)
connect all copper earth wires suitably sheathed in green/yellow sleeving to earth lug.
Connect 2 black cables to neutral block.
Connect either single red (0r 1 of 2 reds) into live block.
connect remaining 3 reds into loop block.

You could have an earth loop which causes a hum/buzzing sound.
Is your computer and powered speakers plugged into different mains?
Connecting amplifiers and speakers to different power sockets will create earth loop problems
This can be fixed by using a single power board connected to a single mains power socket, then connecting all the computer components and powered speakers into this one power board.

Hey austinpippen,
The noise you are experiencing is due to your rca plug shorting out causing a loop, in outher words, bad earth.
Try getting a noise filter, you take your rca plug and plug it into the noise filter, then wire it to the amp!
you can try a ground loop isolator or relocating your ground [earth].
I hope this helps you out.
Fingers crossed.

Sounds like you need a ground loop transformer for each camera. You can get one a electronics shop. Just ask for a ground loop transformer. Connect it inline between the camera and where it's terminated. This will fix you.
