How to Connect Internet Radio to Amplifier
Connecting an internet radio tuner to your amplifier is easier than you think. In most cases you only need one cable and five minutes. This guide walks you through every step and helps you troubleshoot common problems.
What You Need

- Amplifier or AV receiver
- RCA cable, optical cable, or 3.5mm to RCA cable

Which Input Should You Use?
| Input | Use It? | Notes |
|---|---|---|
| AUX | Yes | Best universal choice |
| CD | Yes | Line-level input |
| Tape In | Yes | Line-level input |
| Tuner | Yes | Line-level input |
| Phono | No | Designed for turntables only — will distort |
RCA vs Optical Connection
RCA: Uses the tuner's built-in DAC. Simpler, works with almost any amplifier.
Optical: Sends digital audio to your amplifier's DAC. Better if your amplifier has a superior DAC.
Troubleshooting Common Issues
| Problem | Likely Cause | Fix |
|---|---|---|
| No sound | Wrong input or loose cable | Check input selection and cable |
| Buffering | Weak WiFi signal | Move tuner closer to router |
| Distorted sound | Volume too high or bad cable | Lower tuner volume, try new cable |
| Only one channel | Loose RCA plug | Re-seat both RCA connectors |
| Hum or buzz | Ground loop | Use a ground loop isolator or different outlet |
Setup Tips for Best Sound
- Set the tuner volume to a fixed level (around 70%)
- Control final volume with your amplifier
- Use shielded RCA cables to reduce noise
- Keep cables away from power cords
