Hello
did you check the box for BEO9500 Radio on the Experience mapped to NL page?
My Beomaster 7000 Radio source is shown; see below!
note: the difference to your system and mine: I do have additional NL devices and the Beosystem 7000/BLC combo is set as “connect to (primary)” to a BS35. So as mention before, maybe you’re confronted with BLC limitations.
