An electronic system is responsive to an operating signal from a single input device for determining which of the plurality of user stations is to be operated and what operation is to be performed. The electronic system includes a first user station that receives a signal at a first magnitude and a second user station that receives the signal at a second magnitude. A control circuit is responsive to the first and second magnitudes of the signal for determining one of the first and second user stations to process the signal.
