The Klipsch Reference R-20B soundbar is designed to quickly connect to most TVs. An included digital optical cable connects to your TVs digital output to the back of the soundbar. For the few TVs without an optical audio output, there is a 2-channel analog input. Once connection to your TV is made, you just plug the soundbar into a standard electrical outlet and turn it on. The built-in Dolby Digital Decoder takes over and allows the Klipsch Reference R-20B to automatically reproduce detailed, high-output sound in almost any size room no matter what format of sound is coming from the TVs output.
