Not sure I fully follow your question but the 3 rd ground wire from the turntable would hook up to the ground screw on the imic

Grounding issue


The preferred approach is to run a ground cable from the turntable to the ground post on the back of your preamp or receiver. This keeps buzz and hum out of the audio signal. If your receiver doesn't have a ground post, you'll have to connect the ground to one of the RCA signal jacks. In both cases the question is, when you have two grounds, which one to connect? You'll have to determine this by trial and error. My guess is you'll get the best results by connecting both, so start with this arrangement. Connect the turntable's audio cables from its RCA jacks to the receiver, select the phono input, and turn it on (with the volume turned down). Turn up the volume until you can hear hum or buzz. Then connect a piece of wire to the ground post on the turntable panel and touch the other end to the ground post on the receiver or to the RCA jack/plug's outer ring. If the hum/buzz goes away, you're good to go and can connect the wire permanently. If not, try the ground cables individually and use the connection that works best.

Connect the RCA phono plug wires usually red and white wires with plugs to a receiver or amplifier in the back of it to phono in. New receivers will not work unless you have a phono preamp. Best to buy a vintage stereo receiver or amplifier with the correct connections. Make sure you connect the ground wire which is usually a small black wire coming from the turntable to an receiver or amplifier. Turn the stereo receiver on phono. Connect it to any screw attached to metal on back or look for a ground screw. If you do not attach it it will hum.

Stanton STR8-100 Turntable ground wire?


Hi,
There is no such ground points in the Stanton STR8-100. The main thing you have to check is the RCA cable used. You should a high quality RCA cable suitable for Phono connections. If you use a normal RCA cable then it will produce HUM because if its weak ground shield.

Try with a good quality RCA cable with Good ground shielding.

Technics sl-BD20D turntable, attached pre amp but now have a loud hum, noticed there is a round jack with a pin in it next to the 2 outputs. Is this for grounding? Are there special cables that fit that...


Hi, Yes your turntable needs to be grounded to get rid of hum. Make sure that your turntable, preamp and amp are all powered from the same point. Most preamps do not have a grounding connection on them and when they do it is normally on the same side that the rcas from your turntable connect too. What is the make and model of your preamp. I will check it out. To earth to a preamp without a grounding connection do this. Take the grounding cable from your TT and slip it in the side of one of the 2 rca connections as you plug them in. That will ground your TT to the amp. If it doesn't then swap the ground lead to the other rca. Cheers John. Styluscity.com.

I dont have the orginal ground wire for my Technics SL-BD20D turntable someone told me i could use rca cables to ground it, i have a pre amp cause my main amp didnt have phono jacks on the back of it.


Hello,
You don't need the original ground wire for Technics SL-BD20D turntable,
any plain cable can be used for this purpose...
you should connect turntable to your pre amp,should be a "phone" input at the back...
here are some suggestions for grounding....
---------
  • Plug in a surge protector to the outlet, and then plug all the components into that surge protector
  • Connect a ground plug to the surge protector and then plug the ground plug into the main outlet. A ground plug is available at any hardware store, and turns a three prong connection into a two prong. Ground plugs help eliminate 60 cycle hum.
  • Connect the ground wire from your turntable to the ground wire connection on the receiver. If this doesn't work, looking on the back there should be a grounding point,

    Unplug your receiver.. Split a wire and attach one of the splits to the receiver where you will see the text, "ground" or something similar. Attach the other end to something metal such as a pipe that goes into the ground. Secure with electrical tape. Plug in.
    connect the ground wire to a screw on the electrical outlet.

    What all can I attach a turntable ground wire to?


    Connecting to another piece of equipment besides the mixer introduces the possibility of creating a ground loop, which, of course, is not desirable.

    Just make a splice using Stakons (crimper). Just cut off the existing connector and crimp a (red) round crimp to the existing ground wire. Then take a length of same gauge and crimp a round a (red) spade Stakon on the other end. Then take a nut and bolt and connect the 2 round connectors and tape with good black tape (Scotch 33 or similar). That will get you through the Gig.

    Akai PX-E855K turntable - switchable pre-amp - how?


    To my knowledge this is no switchable pre-amp on this unit. Just connect to your own phono pre-amp and you should be ok.

    I am trying to hook together a computer and a turntable(Turntable has its own pre-amp) & I need a diagram on what wire gos where?


    OK. Since there is a pre-amp, all you need to do is to connect pre-amp output to Line-in input on the PC. This may be a bit of challenge as the connector on the pre-amp and computer are of different types. Usually, you need a cable with RCA connectors on one end and 3.5mm stereo pin (same pin as you have for stereo headphones) on the other.
