Normal Operation
The rear control unit (RCU) (also referred to as the audio unit) sends an amplified, varying AC voltage to the speakers. The AC voltage is converted to sound through the magnetic coil and speaker cone. Each speaker has a signal and return circuit and the number of speakers varies, depending on the system configuration.
