A:Answer Hello docholiday1991,
The HW-Q990B Soundbar has the ability to connect using Digital Optical, HDMI or Bluetooth.
If you are wanting to use the top-firing speakers, these are Dolby Atmos content. Depending on the height of your ceilings, Dolby recommends for an optimal audio experience the ceilings are no taller than 12 to 14 feet.
You will have to use an HDMI cable to access Dolby Atmos content, within the sound settings of your TV you will need to change your audio output to Dolby Digital+ as well. If your TV does not have this setting then it may not be able to produce Dolby Atmos content through the TV. Please refer to the full manual on your TV.
