If it stays loud reguardless of volume it could mean the main Electrolytic Capacitor has failed in the power supply. This will be a big one around 4700UF in value.

SOURCE: 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.

SOURCE: one of my DJ turntables = only left side stereo sound

need to narrow it down, using 1 turn table ONLY with the mixer on channel 1 (the chanel that is working) to test reciever is working properly and sound working on both side of the speakers, this eliminate the first turn table. Next, disconnect the working turn table (1) and connect your second turn table to the same chanel and see if you getting the sound coming chanel 1 just as your first turn table did. If you getting sound coming out from turn table on ch1 than is not the turn table issue. It will be you mixer having problems. You cant solve the problems having everything connected. Testing one turn table at a time using working chanel on the mixer to see if both turn table working properly. If you use the same chanel testing both turn table and the second one does not work than it will be one of your turn table is faulty. Note: if you find and test both of your turn table is working properly than it will be your mixer. good luck and hope that help..

SOURCE: i want to remove the ground cable on my technique

The video you followed may well work ok with some mixers but not others. You will need to check your mixer to see if the ground screw is connected to the ground of the phono sockets, if it is then internally grounding will work, if not then it won't work.

SOURCE: Technics SL-BD22 ground wire does not reduce hum. Any solutions?

I have found out that the female phono plugs on the turntable are sensative and have to have a solid connection and often adjusted from time to time to eliminate the 60 cycle hum.

Loud humming sound


Make sure that the input connection ground is good. If that does not cure the loud hum then you have a power supply issue.

Apart from the suggested solutions shown below, you might also want to consider the turntables power supply as the cause of the hum. Perhaps a faulty mains smoothing capacitor?

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.

The sound is terribly distorted if turn up the volume on my ion profile pro


I am going to hazard a guess, I have lots of experience with traditional turntables, but not with USB turntables. Here is some theory that may also apply to the USB turnbable. Turntables of old and new that are not USB have a GROUND wire (a single flexible conductor not connected to the plug). The ground wire is supposed to go to the chassis of the amplifier or receiver. If it is not used. There will be a 60Hz hum added to the turntable's signal. It makes the sound garbled and unpleasant. Your turntable may have such a wire. If so, ground the wire to the chassis of the computer. If it doesn't have the wire. check to see if you have all three prongs on your terminal strip(the rounded large prong is the ground). If you don't the chassis of the computer will not be grounded so you may get the hum from that source as well. If the outlet that your outlet strip is plugged into does not have a proper ground, then that could be the source.

Check to make sure that there are no breaks of your ground between the turntable and the wall outlet.
Replace the offending cables or parts until you are sure.
If there is a grounding wire coming out of the turntable, connect it to the chassis of the computer.
Here are some other points that are important
Important: All of the power in your computer and sound system should be connected to the same phase of the breaker panel in your house If it goes into the same wall outlet. that is best.
This ground issue is important in turntables.
This may not be the problem, but it certainly is very possible.
I worked in professional sound system design for recording studios and large venue (concert) sound systems.
Whenever possible, these folks require the power to be from a unified phase and source point. on Otherwise they have serious hum issues.
Have a Happy New Year,
Best, mark

Bought a used Martin Logan Dynamo subwoofer a couple days ago and have a very loud hum when the ac cord is plugged in, even if the speaker is not connected to an audio source. The "hum" can be heard in any...


Neither the amp or the sub have grounded power cords.

I have discovered the ML Dynamo takes about 30 minutes to switch to standby in auto mode.

With speaker level inputs connected to the Onkyo A807 amp, both units powered from the same wall outlet, Dynamo sub on Auto, the sub hums for about half an hour after the Onkyo is switched off, then the sub goes quiet. Not so good.

I connected a bonding wire between the two units on 3_7_09. If I smoked some old audio gear I could just look at that as an opportunity, right?

Works fine. Now I have the ML powered from the wall and working normally.

Have a B&O RX-2 with mcc4 and loud hum


Possibly check the wires on the cartridge, make sure none of them are touching and are not bent to badly, are all the connections tight? some cartridges require plastic sleeves over the connections, this insure they don't touch and
avoids resistances between them. Also some cartridges are not compatible with certain model turn tables.Is it universal? Also you my need a mixer most turntables don't work with amps alone. Mine don't. Usually most models you attach the ground wire to the mixer. A mixer boosts table power and take stress off the amp. Hope this helped! good luck!
