    Bluetooth

    Audio latency is the time it takes for audio move from your projector to your Bluetooth speaker. And Bluetooth connection spend a lot more time in the "processing" stage than a traditional wired connection. Plus, Bluetooth connection will be interfered by another signal source such as WiFi. There are some solutions below that you could decrease the latency:

    1. Disconnect other devices from your soundbar. As other devices might try to connect with it and influence the connection to the projector.
    2. Turn off other wireless connections close to the projector and Bluetooth signal.
    3. Keep your distance from other Bluetooth devices to avoid interference.
    4. Change the position or location of your device. It may need to be closer to the video.
    5. Feel free to contact us contact us if the problem still exist.
