What You Need

  • Turntable – make sure it has either a built-in phono preamp or external one available.
  • Amplifier – with either a PHONO input or standard AUX / LINE IN ports.
  • RCA cables – typically red and white connectors.
  • Ground wire (optional) – reduces hum on certain setups.
  • Speakers – passive or active depending on your amp.

Step-by-Step: How to Connect a Turntable to an Amplifier

Step 1 – Check for a PHONO Input

Look at the back of your amplifier. If you see a PHONO input, you can connect the turntable’s RCA cables directly there.
This input already includes a built-in phono preamp that boosts and equalizes your turntable’s weak signal.

Step 2 – Connect Using RCA Cables

Plug the red RCA cable into the red input and the white RCA cable into the white input on the amp.
If your turntable includes a ground wire, attach it to the grounding screw on your amplifier to eliminate hum.

Step 3 – If Your Amp Has No PHONO Input

Many modern amplifiers only have LINE IN or AUX ports. In that case, you’ll need a phono preamp (either external or built-in to your turntable).
Connect the turntable → preamp → amplifier’s line input.

Step 4 – Select the Right Input

On your amplifier, choose the correct input channel (PHONO or LINE/AUX) using the selector knob or input button.
Lower the tonearm gently — and you’re ready to spin your records!


Tips for the Best Sound

  • Keep your turntable away from speakers to minimize vibrations.
  • Ensure the surface is level for proper stylus tracking.
  • Replace worn cartridges and stylus tips for clearer sound.
  • Use shielded RCA cables if you experience background hum.

Troubleshooting Common Issues

  • No sound? Double-check input source and make sure the preamp is active.
  • Hum or buzz? Ensure the ground wire is connected or use a ground loop isolator.
  • Distorted audio? Reduce volume or confirm you’re not sending a PHONO signal into a LINE input without a preamp.
