- Plug the other end of the USB power cable into a 5V USB power adapter (optional, may be included) or a compatible USB port (e.g., on a TV or computer).
- The device does not have a built-in battery and requires continuous power to operate.
5.2. Connecting to an Audio Source
Choose one of the following audio input methods based on your source device:
- Optical (TOSLINK): Use the optical cable to connect the B06TX's "Optical" port to the optical audio output of your TV, PC, or other audio source.
- Coaxial: Use a coaxial cable (not included) to connect the B06TX's "Coaxial" port to the coaxial audio output of your source device.
- 3.5mm AUX: Use the 3.5mm audio cable to connect the B06TX's "AUX 3.5mm" port to the 3.5mm audio output (headphone jack) of your TV, PC, or other audio source.
- 2RCA: Use the 3.5mm female to RCA male cable to connect the B06TX's "RCA" ports to the RCA audio output (red and white ports) of your TV or audio system.
Note: Ensure only one audio input method is connected at a time to avoid conflicts.
6. Operating Instructions
6.1. Power On/Off
- To power on, ensure the device is connected to a power source. The device will typically power on automatically.
- To power off, disconnect the power cable.
6.2. Pairing with a Single Bluetooth Device
- Turn on the B06TX transmitter. The LED indicator should start flashing, indicating it's in pairing mode.
- Put your Bluetooth headphones or speaker into pairing mode. Refer to your device's manual for specific instructions.
- Place the B06TX and your Bluetooth device close to each other.
- The devices should automatically connect. The LED indicator on the B06TX will turn solid blue once connected.
- If pairing doesn't occur automatically, press the "Switch" button on the B06TX to manually initiate pairing mode. You can also press the "Bluetooth 1" or "Bluetooth 2" buttons to initiate pairing for a specific channel.
6.3. Dual Link Pairing (Connecting Two Bluetooth Devices)
The B06TX supports connecting to two Bluetooth headphones or speakers simultaneously.
- First, pair your primary Bluetooth device (e.g., headphones 1) as described in section 6.2.
- Once the first device is successfully connected, press the "Bluetooth 2" button on the B06TX. The LED for Bluetooth 2 will flash.
- Put your second Bluetooth device (e.g., headphones 2) into pairing mode.
- The B06TX will search for and connect to the second device. Once connected, both Bluetooth 1 and Bluetooth 2 LEDs will be solid blue.
- You can now enjoy audio streaming to both devices simultaneously.
6.4. Volume Control
Use the "Vol-" and "Vol+" buttons on the B06TX transmitter to adjust the audio output volume.
6.5. Auto Reconnect
The B06TX features quick pairing and memory auto-connection. Once paired, it will automatically attempt to reconnect to previously paired devices when powered on and within range.
7. Maintenance
- Keep the device in a dry environment, away from moisture and extreme temperatures.
- Clean the device with a soft, dry cloth. Do not use liquid cleaners or aerosols.
- Avoid dropping or subjecting the device to strong impacts.
- Do not attempt to disassemble or repair the device yourself, as this will void the warranty.
8. Troubleshooting
8.1. No Sound or Audio Delay
- Check Connections: Ensure all audio input cables (Optical, Coaxial, AUX, RCA) are securely connected to both the B06TX and your audio source.
- Verify Input Mode: Make sure your TV or audio source is set to output audio through the correct port (e.g., Optical Out, AUX Out).
- aptX/aptX-LL Support: For no sound delay (lip-sync), ensure your Bluetooth headphones or speaker also support aptX Low Latency (aptX-LL) or aptX HD. If your receiving device does not support these codecs, some delay may be noticeable.
- Volume Levels: Check the volume on both the B06TX and your connected Bluetooth device.
8.2. Cannot Pair Bluetooth Device
- Pairing Mode: Ensure both the B06TX and your Bluetooth device are in pairing mode.
- Distance: Keep the devices within close proximity (e.g., 1-3 meters) during the pairing process.
- Interference: Move away from other wireless devices that might cause interference.
- Reset: Try restarting both the B06TX and your Bluetooth device.
8.3. Limited Range
- Obstructions: Walls, furniture, and other objects can reduce the effective range. Try to maintain a clear line of sight between the transmitter and receiver.
- Interference: Other electronic devices (Wi-Fi routers, microwaves) can interfere with the Bluetooth signal.
8.4. Device Only Transmits Audio
- Important Note: The 1Mii B06TX is a Bluetooth transmitter only. It sends audio signals from a source to Bluetooth receivers. It cannot receive audio from Bluetooth devices (like a phone) or connect to gamepads.
9. User Tips
- Cable Length: The included cables (e.g., 3.5mm audio cable) are approximately 1 meter in length. Consider this for your setup.
- Codec Selection: The B06TX automatically selects the best available audio codec (aptX HD, aptX-LL, aptX, AAC, SBC) supported by your connected Bluetooth receiving device. There is no manual mode switching between aptX-LL and aptX HD.
- Elderly/Hearing Impaired Use: This transmitter is ideal for allowing individuals with hearing impairments to watch TV with headphones without disturbing others, thanks to its low latency and dual-link capabilities.
