5. Troubleshooting
This section provides solutions to common issues you might encounter with your Evolve 50 system.
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power | Power cable not connected; Power outlet faulty; System fuse blown. | Ensure power cable is securely plugged into the system and a working outlet. Check the power outlet with another device. Contact service if fuse replacement is suspected. |
| No Sound Output | Master volume too low; Input gain too low; Incorrect input selected; Faulty audio cable; Column array not properly connected. | Increase Master Volume and individual input gains. Verify correct input selection on the DSP. Test with a different audio cable. Ensure the column array is fully seated on the mounting pole. |
| Distorted Sound | Input gain too high (clipping); Master volume too high; Faulty audio source. | Reduce input gain until the input level indicator no longer clips. Lower the Master Volume. Test with a different audio source. |
| Bluetooth Pairing Failure | Bluetooth not enabled on device; Device too far; Interference; Evolve 50 not in pairing mode. | Ensure Bluetooth is on and visible on your device. Move device closer to the Evolve 50. Reduce other wireless interference. Ensure Evolve 50 is set to "Pair Audio Device" in its Bluetooth menu. |
| System Overheating | Blocked ventilation; Prolonged operation at high volume in hot environment. | Ensure all ventilation grilles are clear. Reduce volume. Allow system to cool down in a well-ventilated area. |
