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.
