Rear Seat Audio (RSA)
The audio portion of the rear seat audio controller provides dual audio source capability from the
vehicle audio system.
When in use, the audio portion of the controller enables rear seat occupants to listen to a different
music source than the front seat occupants. The audio volume at each headphone is independently
controlled by the rear passengers. A VF display in the center of the controller provides graphic
communication to the rear seat operator the state of various rear audio functions. The dual source
mode functionality is an embedded feature of the compatible radio receiver. Primary radio
controls always have control of the front speaker outputs. Primary radio mode control is not
affected by the operation of the rear audio control and always has priority over the rear audio
control.
The front seat occupants have the capability to override and disable the rear audio controller
operation through the primary radio controls. An ignition cycle also causes the rear audio to
default to the OFF state.
Even when the primary radio is powered OFF, shutting off all speakers in the vehicle, the RSA
controller functions are available. The rear passengers can still listen to any available audio
source through the headphones.
The controller shall have 2 stereo volume controls to vary the audio volume to the headphones.
For each headphone, one element will provide the variable load to the left audio output and the
other element will provide the variable load to the right audio output.
