7. Troubleshooting
If you experience issues with your GST-G Garden Speaker, refer to the following common troubleshooting steps:
- No Sound:
- Ensure the 70V amplifier is powered on and functioning correctly.
- Check all wiring connections between the amplifier and the speaker for looseness or damage.
- Verify the correct power tap setting on the speaker.
- Confirm the audio source is active and sending a signal to the amplifier.
- Distorted Sound:
- Reduce the volume level on your amplifier. Overdriving the speaker can cause distortion.
- Check for damaged wiring or loose connections.
- Ensure the speaker's power tap setting is appropriate for the amplifier's output.
- Uneven Sound Coverage:
- While the speaker offers 360-degree dispersion, ensure no large obstructions are directly blocking the sound path.
- Consider adding more speakers for larger or irregularly shaped areas.
If problems persist after following these steps, contact customer support.
