I asked Devialet tech support to clarify how to set up 2 phantoms with a TV and get no audio delay.
Their Oct 26 reply:
Your questions have been reviewed and our technical department has responded with this answer for you below:
Phantom has a constant latency of 160ms regardless of the source (optical/Bluetooth or Spark).
Every devices usually possesses its own latency.
Several solutions exist to compensate this lag. For instance, most televisions allow you to adjust audio and video synchronization (often called A/V sync or Lip sync)
For an audio/video use, it is up to the user to synchronize the image and sound.
In order to do so, several solutions exist :
From a TV using an HDMI signal or from a tuner. Simply adjust the latency on the TV to 160ms.
From a TV using an HDMI signal from a router (if it has an optical output). Use the optical output of the router (which can be set in advance with respect to the video) and possibly also adjust the latency on the TV.
From a computer. A player like VLC adjusts precisely latency audio and video streams separately.
From a DVD deck or Blu-Ray. Some models (such as OPPO-103 for instance) are able to handle the audio / video latency at a rate of +/- 200 ms, that is to say in the range of what we have to correct.
