Introduction
The 1Mii Bluetooth 5.0 Transmitter Receiver is a versatile audio device designed to add Bluetooth capabilities to your existing audio equipment. It can function as a Bluetooth transmitter (TX mode) to send audio from non-Bluetooth devices to Bluetooth headphones or speakers, or as a Bluetooth receiver (RX mode) to stream audio from your Bluetooth-enabled devices to non-Bluetooth speakers or stereo systems.
Key features include high-resolution audio support, a pass-through mode for simultaneous wired and wireless audio, an LCD screen for easy pairing, and minimal lip-sync delay.

Device Overview
The 1Mii Bluetooth 5.0 Transmitter Receiver features various ports for audio input and output, along with control buttons and an LCD screen for operation. Familiarize yourself with the device's layout before proceeding.
Powering On the Device
Connect the provided charging cable to the device's USB power port and plug the other end into the included power adapter or a compatible USB power source. The device will automatically power on.
Operating Instructions
Switching Between Transmitter (TX) and Receiver (RX) Modes
Locate the TX/RX mode switch on the device. Slide the switch to the desired mode. The LCD screen will display the current mode (TX or RX).
Transmitter (TX) Mode Operation
In TX mode, the device transmits audio from a non-Bluetooth source to Bluetooth headphones or speakers.
- Connect the 1Mii device to your audio source (e.g., TV, PC, CD player) using the appropriate audio cable (Optical, RCA, or 3.5mm AUX).
- Ensure the device is in TX mode. The LCD screen will show "TX".
- Put your Bluetooth headphones or speakers into pairing mode.
- The 1Mii device will automatically scan for nearby Bluetooth devices. Use the navigation buttons to select your device on the LCD screen and press the pairing button (often the main control knob or a dedicated button) to connect.
- Once connected, the LCD screen will display the connected device's name.
Receiver (RX) Mode Operation
In RX mode, the device receives audio from a Bluetooth-enabled source (e.g., smartphone, tablet) and outputs it to a non-Bluetooth speaker system.
- Connect the 1Mii device to your non-Bluetooth speaker or stereo system using the appropriate audio cable (Optical, RCA, or 3.5mm AUX).
- Ensure the device is in RX mode. The LCD screen will show "RX".
- On your Bluetooth-enabled source device (e.g., smartphone), go to Bluetooth settings and search for "1Mii B03Pro+" or a similar name. Select it to pair.
- Once connected, the LCD screen will display the connected device's name.
Pass-through Mode
The pass-through mode allows you to simultaneously output audio to both wired speakers and Bluetooth headphones/speakers. This is useful when you want to listen wirelessly while others listen through wired speakers connected to the same audio source.
To use pass-through, connect your audio source to the 1Mii device's input, and connect your wired speakers to the 1Mii device's output. Then, pair your Bluetooth headphones/speakers as usual in TX mode.
Audio Codec Selection
The device supports various high-quality audio codecs, including LDAC, aptX HD, and aptX Low Latency. The LCD screen will indicate the active codec when connected to a compatible device. LDAC provides the highest resolution audio, while aptX Low Latency minimizes audio delay, ideal for watching videos.
Volume Adjustment
Use the volume up and down buttons on the device to adjust the audio output level.
Maintenance
Cleaning
Wipe the device with a soft, dry cloth. Do not use liquid cleaners or solvents.
Storage
Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
Common Issues and Solutions
Device Does Not Power On
- Ensure the USB power cable is securely connected to both the device and a working power source.
- Verify the power adapter is functional.
Difficulty Pairing
- Ensure the 1Mii device is in the correct mode (TX for transmitting, RX for receiving).
- Place the 1Mii device and the target Bluetooth device close to each other.
- Put the target Bluetooth device into pairing mode.
- If pairing takes longer than expected, allow several minutes for the devices to establish a connection, especially during the first pairing attempt.
- Try clearing previously paired devices from the 1Mii device's memory by pressing the volume up and down buttons simultaneously (refer to the device's specific instructions for this function).
- Restart both the 1Mii device and the target Bluetooth device.
No Audio Output
- Check all audio cable connections (Optical, RCA, AUX) between the 1Mii device and your audio source/speakers.
- Ensure the correct input/output is selected on your audio source/speaker system.
- Verify that the 1Mii device is successfully paired and connected to the target Bluetooth device (in TX mode) or the source Bluetooth device (in RX mode).
- Adjust the volume on both the 1Mii device and the connected audio equipment.
Poor Audio Quality or Distortion
- Ensure all cables are securely connected and not damaged.
- Move the 1Mii device closer to the paired Bluetooth device to reduce interference and improve signal strength.
- Avoid placing the device near other wireless devices that may cause interference.
- If using LDAC or aptX HD, ensure both the 1Mii device and the paired device support the codec for optimal performance.
Audio Delay (Lip Sync Issues)
- While the device is designed for low latency, ensure that if you are watching video, your paired Bluetooth headphones/speakers also support aptX Low Latency for the best experience.
