FORD 2009 F-550 v.3 - Manual (Page 66)

Single Play: Single play consists of all occupants in the vehicle listening
to the same playing media over the front and rear speakers. When the
DVD system is on, and the same source is playing through the front and
rear speakers, SINGLE PLAY will appear in the front radio display.
Dual Play: Dual play is when the rear seat passengers choose to listen
to a different playing media than the front seat passengers. With the
DVD and Rear Seat Controls turned ON, the rear seat passengers may
choose to listen to the radio, CD, MP3, DVD, or DVD-AUX media sources
over headphones while the front speakers play the chosen selection for
the front audio system, they may listen to another over the headphones.
DUAL PLAY will appear in the radio display.
When both the front seat passengers and the rear seat passengers listen

passengers can also listen to the radio; however, they will be limited to
listening to the same radio channel.
