Most Home Theater/Surround Sound receivers have multiple types of inputs and outputs, and multiple sets of each kind, allowing you to connect many different analog and digital devices.
TV sets often do not have enough jacks available to connect all the entertainment devices needed.
By connecting your entertainment devices and cable set-top terminal through a Home Theater/Surround Sound receiver, you'll have greater ease of use, as well as the best sound and picture possible.
A Home Theater/Surround Sound receiver in turn, is connected to your TV. By using the remote provided with your Home Theater/Surround Sound receiver, you can determine which home entertainment device is active and feeding your TV.
Note: The Home Theater/Surround Sound receiver must be turned on to supply sound and picture to your TV.
