Troubleshooting
If you encounter issues with your Audio Pro A28 speakers, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from speakers | Power not connected; incorrect input selected; volume too low; speaker cable loose. | Check power connection; verify correct input is selected (e.g., HDMI ARC, Optical); increase volume; ensure speaker cable between left and right units is securely connected. |
| Bluetooth pairing issues | Speakers not in pairing mode; device too far; interference. | Ensure speakers are in Bluetooth pairing mode; move device closer to speakers; minimize interference from other wireless devices. |
| WiFi connectivity problems | Incorrect WiFi password; weak signal; network issues. | Verify WiFi password in the Audio Pro app; ensure speakers are within WiFi range; restart your router and speakers. |
| No sound from TV via HDMI ARC | TV ARC not enabled; incorrect TV audio output settings; speaker not selected as output. | Ensure HDMI ARC is enabled on your TV; check TV audio settings to output sound to external speakers (PCM format is generally recommended, as the A28 may not decode Dolby Digital); select the HDMI ARC input on the speakers. |
| Remote control not working | Dead batteries; obstructed path; remote not paired (if applicable). | Replace batteries; ensure no obstructions between remote and speaker; refer to the app for remote pairing instructions if necessary. |
If the problem persists, try resetting the speakers to factory settings (refer to the full manual or Audio Pro app for specific instructions) or contact Audio Pro customer support.
