Audio

Your soundbar can connect to your television in four different ways.

  • Optical
    Optical works for most televisions and is the most common, and best supported way to make the connection to your soundbar.
  • Coaxial (Coax)
    Some televisions have a coax port, but it is not very common.
  • RCA to Aux/Aux to RCA
    Again, this is not a common output, but some televisions can use either an RCA-to-minijack or minijack-to-RCA connection.

3. Optical Connection

Optical allows you to use a simple, single-wire connection from your television to your sound bar to enjoy all your media with your new soundbar automatically.
