vpi classic to musical fidelity mxvyl phono section which has a grounding post next to rca ( 2 prong dc conv plug for power ) then Rca to my intergrated amp . which also has a grounding post for its onbaord phono section which i was using until now .the mxvynl is new..Thats why i was curious if i should go from mxvynl to intergrated ground ?or it would cause a loop..i am not going to do that and will just roll with a tt to phono ground as per info.

erik_squires Yes, and the safety ground is connected to the chassis of the equipment it goes to. The screw/thread/ground connector next to the turntable input is connected to what, exactly? :-)It is connected to the phono cartridge, which is an inherently balanced system. That is, it has a hot and separate neutral for each channel, plus a ground. |
Technically? To the signal ground of the phono preamp. The signal ground is connected to chassis. The fact that the preamp may also use the safety equipment ground, that is also connected to the chassis is irrelevant. The safety equipment ground is there in the event of a hot to chassis ground fault. The whole audio system could consist of equipment that uses double insulated AC power wiring and doesn’t use the safety equipment ground at all. Including the TT, no equipment ground. Where is the earth connection now? Disconnect the TT ground wire from the ground terminal post on the phono preamp and a buzz will be heard through the speakers. Reconnect the ground wire, no buzz.

Connect the TT ground wire to the mxvynl ground post. You are no longer using the onboard phono preamp. The VPI TT doesn't even know it exists. |
