Getting started
3. Connecting the AMBEO Soundbar to the
power supply system
Connect the AMBEO Soundbar to the power supply system - the
AMBEO Soundbar comes to life and guides you through the initial
switch-on process (> 27).
4. Starting the room calibration
For an optimum spatial sound experience, the AMBEO Soundbar
must perform a room calibration. Connect the microphone for the
room calibration and start the calibration. The calibration takes only
a few minutes and leads to the best possible 3D spatial sound (> 28).
