The Right Channel may refer to one of a pair of Channels in a Stereo configuration, which is primarily used for music. It may also refer to a channel meant to be positioned to the right of the screen in a 
Surround Sound configuration. For 
Matrix Surround the Right Channel may be used to derive additional 
Center and 
Rear Channel signals, along with the Right Channel signal.
Mono audio for movies may either be delivered only to the 
Center Channel, or divided between the 
Left and Right Channels.
The Right Channel may be referred as simply Right, as in the Channels are Left, 
Right, Center, 
Left Surround, and 
Right Surround.
