Now that you have plugged in and powered on your TV and your soundbar, you will need to establish the HDMI connection ports on each device, respectively.
In most cases, you will find the HDMI input (ARC) port in the same location as other ports. So if you already have cables plugged into RCA jacks, look there first!
Once you have found this port and made sure that the Soundbar is plugged into a power source, you will be ready to pair the Soundbar with your TV via an HDMI cable.
