    Hi Jan

    We do not support lip-sync grade synchronisation with Bluetooth and have never professed to. We do support lip-sync on the POWERNODE if connected via optical or HDMI.

    Hi Tony

    Thank you for your answer (?) where the only information is that you do not support lip-sync on bluetooth but support lip-sync on optical and HDMI. To start with Powernod 2 do not have a HDMI connection. Secondly both your suggestions need a cord. What I am looking for is at wireless connection. And in your broschyr there is no cord between the TV and the Bluesound product. 

    Looking at your presentation of the product I can find nowhere any information that lip-sync is not supported. Instead it is stated that "aptX® Bluetooth wireless built-in". And the aptX-codes is just created to minimize audio latency. Only that information gives me the conclusion that lip-sync via Bluetooth is supported. 

    Further your Internet homepage states that: "With state-of-the-art Bluetooth® aptX® HD, the NODE 2i can easily support 24-bit streaming directly from your phone or tablet, as well as transmit studio-quality music to Bluetooth headphones and speakers". Does this indicate that the might be an Audio latency about 350 ms?

    Incidentally I did connect via the optical input on my Node 2i. And the audio latency was kept within 20 ms. But then the possibility to pair the Powernod 2 with the Node 2i went crazy. The sound was just fluttering in both systems. 

    So once again, what is the purpose to provide Bluetooth connection when the audio latency is about 350 ms?

    Bluetooth is designed as an audio source to listen to audio tracks from your phone or tablet such as music files stored there or 2 channel streaming services.

    If you are trying to connect a video display, this will require a proper cabled connection using an optical or HDMI connector from your display to the Player in order to handle the complications of true audio/video streaming.

    Yes Tony

    I understand. You must have a cord connection to get rid of the Adio latency. But where do I find this information? Isn't that vital fo buyers? 

    In searching for a Bluetooth receiver to fix the problem I have not yet found a Bluetooth receiver with a audio latency of as much as 350-400 ms. So why should I buy one for 8000 Swedish kronor? 

    Fix it!
