How to Connect a Turntable to Powered Speakers

Updated July 2, 2026 · ConnectWizard

To connect a turntable to powered speakers, run RCA cables from the turntable to the speakers' RCA inputs. If your turntable has a built-in preamp (or 'LINE' switch), connect directly. If not, you'll need a phono preamp between them, because phono-level signal is too quiet for powered speakers alone.

Connection Methods

RCA Direct (turntable with preamp) 🔌 Wired

Set the turntable's switch to LINE (if it has one).
Connect RCA cables from the turntable to the powered speakers' RCA input.
Connect the speakers' power and the ground wire if provided.
Set the speaker input to the matching RCA/AUX source.

Pro Tips

No preamp and no LINE switch? Add a phono preamp in between.
Always connect the ground wire to avoid hum.
Active/powered speakers have the amp built in — no receiver needed.

Frequently Asked Questions

Do I need a preamp for my turntable?

Only if the turntable lacks a built-in phono preamp and your speakers have no phono input. A phono preamp boosts the signal to line level.

Why does my turntable hum through the speakers?

Connect the turntable's ground wire to the speaker or preamp ground terminal to eliminate the hum.
