Hello. Is the method you are currently using providing a stereo signal?
To set up in Optical Direct mode, one MUST configure each Phantom I, otherwise both will receive a mono signal. While the app may provide functionality for setting up 2 Phantoms in stereo via wifi it doesn't offers this for TOSLINK / Ethernet connections. Use a web browser - it is a bit more advanced but is the best method. You would need to contact Devialet and ask if this is applicable to the Ultimate or other versions of the Phantom.
Follow these steps. Note that once in Optical Direct mode all wifi and BT functionality is no longer active.
1. Ensure firmware is at minimum version 2.11.
2. Put the Phantom in Setup Mode: Press the rear button on the Phantom three times quickly.
3. Connect via Ethernet: Wire the Phantom directly to your router.
4. Find the IP Address: Use a network tool (e.g., Network Analyzer) to find the Phantom's IP address.
5. Access the Browser: Type the IP address into a web browser (e.g., http: //172.16.1.3/).
6. Configure: Within the browser, you can adjust settings such as name, maximum volume, and channel mapping (Mono/Left/Right). I've attached a screen capture so you can see the setup screen.
Hope this info is useful to those who wish to use Optical Direct mode.
