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 two 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.
