It’s all about power.
All off.
Turn on tv = video
- Also turn on soundbar = TV / soundbar only
- Turn off soundbar, turn on Connector = TV Connector only
- Turn on soundbar = Both
Wires and connectors and splitters needed is up to your gear. You’ll need normal sound from somewhere and sound outputting to the Connector somehow.
My tv has speaker out connectors. It also has optical out. Speakers are connected for normal sound. The Connector is connected to optical. I can mute the tv and just listen via the Connector because mute doesn’t affect optical. The V2 version of the Connector has a power button that I turn on or off as I wish.
The soundbar needs input. Is it HDMI? Optical? Does it have optical out? Does the tv? Would you need an optical splitter? Is there an amp in the mix like 5.1?
The Connector can also take a standard 1/8" (3.5mm) cable.
