2. Audio Input Connection
Choose one of the following audio input methods to connect the B06TX+ to your audio source (TV, PC, home stereo):
- Optical (TOSLINK): Use the Optical Cable to connect the transmitter's Optical IN port to your device's Optical OUT port.
- Coaxial: Use a Coaxial cable (not always included) to connect the transmitter's Coaxial IN port to your device's Coaxial OUT port.
- AUX/RCA: Use the 3.5mm Audio Cable for a 3.5mm jack, or the 3.5mm Female to RCA Male Cable for RCA (red/white) audio outputs. Connect to the transmitter's 3.5mm AUX IN port.

3. TV Audio Settings (for Optical/Coaxial)
If you are using the Optical or Coaxial audio input, it is crucial to configure your TV's audio output settings correctly. Navigate to your TV's audio settings menu and ensure the audio format is set to PCM or Stereo. The B06TX+ does not support Dolby or DTS audio formats, and incorrect settings may result in no sound.

Troubleshooting
- "Waiting" screen / Cannot search for Bluetooth signals: Briefly press the magnifying glass button until the display shows "Searching".
- No sound when using Optical/Coaxial connection: Ensure your TV's audio output format is set to PCM or Stereo. Dolby/DTS formats are not supported.
- Audio delay (lip-sync issues): For aptX Low Latency (LL) functionality, both the B06TX+ and your Bluetooth headphones/speakers must support aptX LL. If only one device supports it, or if two devices are connected, the transmitter may use other codecs (e.g., SBC, aptX) which can introduce a 70-200ms delay.
- TV internal speakers mute: When using the B06TX+, your TV's internal speakers might automatically mute or stop working. This behavior is dependent on your TV model.
- Volume +/- buttons not working: The volume control on the B06TX+ may not function if your connected device does not support the Audio/Video Remote Control Profile (AVRCP).
- Cannot pair with phone/tablet/PC directly: The 1Mii B06TX+ is a Bluetooth transmitter only. It is designed to send audio from non-Bluetooth sources to Bluetooth receiving devices (headphones/speakers), not to receive audio from phones or other Bluetooth sources.
- Incompatibility with AirPods Pro 2nd Gen: The B06TX+ is compatible with most AirPods models but is specifically incompatible with AirPods Pro 2nd Generation.
- No support for online calls, musical instruments, or karaoke: This adapter does not include a microphone and is not designed for two-way audio communication or real-time instrument transmission.
User Tips
- Optimal Audio Sync: For the best audio-visual synchronization, ensure both your Bluetooth headphones/speakers and the B06TX+ support aptX Low Latency.
- TV Audio Configuration: Always double-check your TV's audio output settings, especially for optical or coaxial connections, to ensure it's set to PCM or Stereo to avoid sound issues.
- Single vs. Dual Connection: While the dual-link function is convenient, be aware that connecting two devices might disable aptX HD/LL, potentially introducing a slight audio delay. For critical listening or gaming, consider using a single connection with aptX LL compatible devices.
- Range Optimization: For longer range and stronger connection, ensure the transmitter has a clear line of sight to your Bluetooth receiving devices and minimize obstructions.
