• 2). Plug the red plug on the RCA cable into the red connection on the back of your receiver, then plug the white plug on the RCA cable into the white connection.
  
  
• 3). Locate a red and white input on the back of your home theater receiver.

Using an Optical Audio Cable

• 1). Locate the optical output on the back of your DirecTV receiver. It will be marked "Digital Audio Output." (Not all DirecTV receivers have the optical output; if your receiver doesn't, connect using an RCA cable.)
  
  
• 2). Slide the plug on the end of the optical cable into the optical output on the back of the receiver. The plug will only fit one way, so don't force it in.
  
  
• 3). Locate the optical audio input on the back of your home theater receiver. The input will have a red light in the middle of the connection and will be marked "Input."
  
  
• 4). Slide the end of the optical cable into the optical audio input. Remember not to force it.
