Ground Wire!?

i keep hearing stuff about a ground wire. on some DJ site, i saw this "make sure your turntables are electrically grounded so the static electricity can not make a terrible mess of the music you play. (if you fail to do so the music will hiss and crackle from static charge that builds up.)" Can someone explain what the ground wire is, and what purpose it serves? (BTW i dont have turntables yet)

It goes between the turntables and the mixer, and just earths the turntables, I think. You get a nasty hum without them, presumably because if you have vinyl rubbing on things you get a static buildup that will interfere with the signal going through the cables. They're actually built into the cables that go between your turntables and mixer carrying the audio signal, but separate at the end, so you just attach them to their little widget. It's not something you have to go and get separate from your decks or anything.

on turntables you have.....the RCA's (left & right/white & red) wire, the power cord, and the ground wire....

you simply connect the ground wire to your mixer's ground...it illiminates hum and any other static noises

something along those lines....im no electrician

The signal goes to your mixer as a very small voltage. And this voltage is measured in reference to 0 volts. The ground wire connect to the earth in the mixer (which should be 0 volts) so that there is some kind of steady reliable reference to keep the signal from your turntables accurate.

hey liquid, i just bought concorde djs but the booklet doesnt give alot of info such as height of cartridge, stylus pressure etc. can you tell me how you set yours up? like what you have your balance weight on and the height. also what is the difference between dj e and dj s, i know that its cause the needle is either spherical or elliptical but what is the difference? thanks.

I think records are originaly cut with an elliptical needle and so the elliptical needles are supposed to sound more "true" to the original. Don't quote me on that. I have NC E and they recommend to be set at 2-5g.

records aren`t cut, they`re pressed

I just emailed my friend

Posted by DJ LIQUID on Aug-23-2002 02:00:

My friend replied and this is what he said

The hight of the tonearm will be parallel to the platter ======= and the weight will be between 2 and 4 grams. most dj's use 7 grams to hold the groove in unstalbe situations. at home 4 will be fine for you.

these are the words from the master himself

Posted by Arty on Aug-23-2002 19:09:

The exact weight should depend on the cartridge/needles you're using. It should say in the booklet you get with it. You might want to reduce it from that though in order to preserve your needles, so long as you don't have skipping problems.
