Some turntable cables bundle the audio and the ground into a single assembly, with the thin ground wire running alongside the RCA pair. This keeps the connection tidy and ensures the ground is never left behind when you unplug and reconnect.
Turntable Cable with Ground: The Combined RCA and Ground Assembly
Quick Answer / Summary: A turntable cable with ground combines the shielded stereo RCA pair and a separate ground wire into one assembly, so the phono signal and the hum-draining ground are routed together from the turntable to the phono input.
What a Combined Ground Cable Is
A turntable cable with ground is a stereo RCA cable that also carries a separate ground conductor, usually a thin wire with a spade or bare end that emerges next to the two RCA plugs at the amplifier end.
Signal and ground together
The ground conductor is electrically separate from the audio signal, but physically bundled so the whole connection travels as one cable. This is convenient for turntables that use a single detachable output.
On some turntables, the ground is carried through a dedicated pin inside a 5-pin DIN connector at the turntable end, splitting out to two RCA plugs plus a ground lead at the other end.
Advantages of the Combined Cable
The main advantage is simplicity: one cable carries the signal and the ground, so there is no separate ground wire to lose or forget. Reconnecting the turntable is a single operation.
One clean run
Bundling the ground alongside the shielded audio conductors also keeps the back of the turntable and amplifier neat, with one clean run instead of two or three loose wires.
For a turntable with a built-in multi-pin output, the combined cable is often the only practical option, and it guarantees the ground is connected correctly every time.
Connecting a Turntable Cable with Ground
Plug the red and white RCA connectors into the right and left phono inputs, then attach the ground lead to the amplifier or preamp ground terminal and tighten the screw firmly.
If the cable uses a DIN or mini-DIN plug at the turntable end, seat it fully and lock it if the connector has a locking ring.
Keep the combined cable away from power cords and power supplies, and avoid tight coils, since a long or looped ground run can pick up interference.
When to Choose a Combined vs Separate Cable
Choose a combined ground cable when your turntable uses a multi-pin output or when you value a clean single-cable connection. It is also the natural choice for turntables with a built-in hardwired bundle.
Choose separate RCA and ground wires when your turntable has standard detachable RCA jacks and you want to upgrade the signal cable and ground independently.
Either approach works as long as the ground is connected; the hum behavior depends on the shielding and routing more than on whether the ground is bundled or separate.
Turntable Cable with Ground vs Separate Wires
| Feature | Combined cable | Separate wires |
|---|---|---|
| Wiring | RCA pair plus ground in one | RCA pair and ground apart |
| Convenience | Single connection | Two connections |
| Upgrade path | Fixed bundle | Independent upgrade |
| Common on | Multi-pin turntables | Detachable RCA turntables |
Real-World Application Scenarios
A turntable with a 5-pin DIN output uses a combined cable that splits to RCA plus ground at the preamp; a tidy-minded user prefers a single bundled cable to keep the rack clean; a vinyl listener upgrades from a built-in cable to a detachable combined cable with better shielding.

Frequently Asked Questions
What is a turntable cable with ground?
It is a stereo RCA cable that also carries a separate ground wire, bundling the phono signal and the hum-draining ground into one assembly.
Where does the ground lead on a turntable cable go?
The ground lead attaches to the ground terminal marked GND or earth on the amplifier or phono preamp, next to the phono inputs.
Is a combined ground cable better than separate wires?
It is more convenient, but sound quality depends on shielding and routing; both work when the ground is connected securely.
Can I connect a turntable without the ground wire?
It may work, but you will likely hear hum, since the ground wire is what drains the stray current that causes it.
