Just one more thing in order to better understand how the setup will work.
The Passive is a device, that can be used in different ways.
For your purpose it is ‘just’ an amplifier that drives your passive speakers.
The sound signal (and the needed turn on/off commands) comes through the Powerlink MK2 cable – only one is needed.
All controlling is done in the Ouverture directly or via the ir sensor there with a B&O remote.
