Can I connect a turntable with earth cable to an Onkyo CR515

hi,

instead of plugging your turntable into "phono in" on the amp just try a regular auxilary input like aux ,video, or cd. sounds like the turntable output isnt like the old ones and may be just a regular output.

Hi
I have managed to find a manual for your Onkyo machine. It is in pdf format so can be saved to your computer for future reference. It can be obtained here:
http://www.uk.onkyo.com/downloads/1/1/7/3/6/21507518_65197b9e73.pdf
and by using the Adobe Acrobat Reader search function with "turntable" as the search term, I found diagrams on page 36 which clearly showed how to connect various types of turntable.
Hope this helps
Cheers

This sounds like a wiring problem. Perhaps a faulty earth connection inside the lead or the plugs to and from the turntable. Also check the connections to the cartridge, they can become loose or be connected wrong. Say a channel to the earth connection.

Auxiliary will work but its not intended for phono ( record player ).
The turn table doesn't have a amp so the sound will be lower.
Where as auxiliary is designed for digital connection ( mp3 Laptops etc ) that have they own pre amp.
all the turn tables I have use need to be Earthed to the amp via a earthing tag or you will get a bad sound.
Hope this helps.

The noise will be earth feedback. You might need to connect a wire to an earth point on the turntable - that goes to earth (a metal pipe etc). Sometimes the earth feedback is caused by the earth cable (green/yellow) in the plug either connected or not!

Some amps have Earth connections for them. But any kind of metal might do it.

One of the cables has a bad connection.

Hi, slip the ground cable in the side of the rca connection to the device without earth point.It makes no difference if it goes in the left or right jacks. [email protected]

Fasten the ground to one of the metal screws that hold the metal(?) cover on.You want to connect it to the metal frame of Onkyo.

Yes first check is that the Gnd wire from your turntable is connected to the Gnd (ground) post at the back of your amplifier with a good clean tight connection.
If the problem persists, check ALL your hi-fi components mains plugs for earth connections including your turntable, then remove the earth connections on all but one component so that you are left with only item earthed.
What does sometimes cause problems is if 2 or more hi-fi separates are earthed and connected to each other the earth cables along with the hi-fi interconnects form an inductive loop that picks up interferance such as mains hum etc.
