Troubleshooting
- No Sound:
- Ensure the B06HD+ is powered on and fully charged.
- Verify that the B06HD+ is correctly connected to your audio system (amplifier, speakers, etc.) using the appropriate cables (RCA, Optical, Coaxial).
- Check that your audio system's input is set to the correct source (e.g., "AUX", "Optical", "Coaxial").
- Confirm that your Bluetooth device is successfully paired and connected to the B06HD+.
- Adjust the volume on both your Bluetooth device and the connected audio system.
- Cannot Pair:
- Make sure the B06HD+ is in pairing mode (flashing Bluetooth icon on OLED display). If not, press the Bluetooth button.
- Ensure your Bluetooth device's Bluetooth is enabled and it's searching for new devices.
- Move your Bluetooth device closer to the B06HD+.
- Try restarting both the B06HD+ and your Bluetooth device.
- Clear previous Bluetooth connections on your device if you're having trouble connecting.
- Poor Sound Quality / Disconnections:
- Ensure there are no significant obstacles (walls, large metal objects) between the B06HD+ and your Bluetooth device.
- Move away from potential sources of interference (Wi-Fi routers, microwaves).
- Check if your Bluetooth device supports the high-quality codecs (LDAC, aptX HD) and if they are enabled.
- Ensure the B06HD+ is adequately charged.
- Device Not Responding:
- If the device becomes unresponsive, try pressing and holding the power button for an extended period (10-15 seconds) to force a restart.
User Tips
- Car Audio Connection: The B06HD+ can be used in a car with an auxiliary (AUX) input. Connect the RCA outputs of the B06HD+ to an RCA to 3.5mm adapter, then plug the 3.5mm end into your car's AUX jack. Ensure the car stereo is set to the AUX input.
- Single Audio Stream for Multipoint: While the device supports connecting to two Bluetooth sources simultaneously, only one device can play audio at a time. To switch, simply pause the current playback and start playing on the other connected device.
- Optimal Sound Quality: For the best audio experience, ensure your source device supports LDAC or aptX HD codecs and that these are enabled in your device's Bluetooth settings.
- Power Supply: Always use a 5V power adapter for charging to prevent damage to the unit.
