Examples of connections:

6. Operating Instructions

6.1 Power On/Off

Locate the single control button on the Alctron BX-2. Press and hold this button to power the device on or off.

6.2 Bluetooth Pairing

1. Ensure the BX-2 is powered on. It will automatically enter pairing mode, indicated by a flashing LED (specific LED color/pattern not provided, refer to device for visual cue).
2. On your smartphone, tablet, or PC, navigate to the Bluetooth settings.
3. Search for available Bluetooth devices. The BX-2 should appear in the list (device name not specified, typically 'Alctron BX-2' or similar).
4. Select the BX-2 to initiate pairing. Once connected, the LED indicator will typically show a solid light or a different flashing pattern.

6.3 Audio Transmission

Once paired, your audio source device (smartphone, PC, etc.) will transmit audio wirelessly to the BX-2. The BX-2 then outputs this audio through its XLR connection to your connected audio equipment. Ensure the volume levels on both your source device and the receiving audio equipment are adjusted appropriately.

The maximum effective transmission distance is 10 meters (approximately 33 feet). For optimal performance, keep the paired devices within this range and minimize obstacles.

7. Maintenance

• Keep the device dry. Avoid exposure to moisture, rain, or humidity.
• Clean the device with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
• Avoid extreme temperatures. Do not store or operate the device in very hot or cold environments.
• Handle with care. Do not drop or subject the device to strong impacts.
• When not in use for extended periods, store the device in a cool, dry place and ensure it is fully charged periodically to maintain battery health.

8. Troubleshooting

8.1 No Power

• Ensure the device is charged. Connect it to a USB power source and allow it to charge for at least 30 minutes before attempting to power on again.
• Press and hold the power button for a few seconds to ensure it's not just a short press.

8.2 Cannot Pair with Bluetooth Device

• Make sure the BX-2 is powered on and in pairing mode (LED flashing).
• Ensure your source device's Bluetooth is enabled and it is searching for new devices.
• Move the BX-2 closer to your source device (within 10 meters).
• Turn off and on the Bluetooth on your source device, then try searching again.
• If previously paired, try 'forgetting' or 'unpairing' the BX-2 from your source device's Bluetooth list and then re-pair.

8.3 No Sound or Poor Sound Quality

• Check that the BX-2 is securely connected to the XLR input of your audio equipment.
• Verify that the BX-2 is successfully paired with your source device.
• Adjust the volume levels on both your source device and the connected audio equipment.
• Ensure the BX-2 and your source device are within the 10-meter transmission range and there are no significant obstructions.
• Check for potential interference from other wireless devices (Wi-Fi routers, other Bluetooth devices) and try moving away from them.

9. User Tips

• For best audio quality, ensure your source device is playing high-quality audio files.
• Keep the BX-2 and your transmitting device in line of sight if possible, especially in environments with many wireless signals, to maintain a stable connection.
• Always fully charge the device before important use to avoid interruptions.
