Do stereo Phantoms connect wirelessly to Dialog or Wifi Router or both?

[EvPa]

Do you mean when your router is connected via ETHERNET cables to your Phantom?  Or do you mean your wireless router connect wirelessly with your Phantom - WHEN the Dialog is SHUT DOWN?

I was talking about Phantoms connected to a router via Ethernet cables.

In "wireless" mode, the stereo pair will still work for a short while, the Phantom not connected to the optical source will then stop playing.
