Abstract: A “flame show” is responsive to an audio input signal such as music. A base unit including an analog base unit controller circuit is arranged to receive an audio input signal and generate an analog control signal that is responsive to the audio input signal. The analog control signal is distributed, by wire or wireless, to one or more flame display units such as a “tiki torch.” Each flame display unit has a fuel source, and a proportional valve for controlling an amount of fuel supplied to a burner. Preferably, the control signal controls a gate terminal of a MOSFET semiconductor device, which in turn is coupled to control current in the proportional valve each each unit. By deploying multiple flame display units, all coupled to the same base unit, all of the flame display units contribute synchronously to the overall flame show.
