Abstract

See full text

An example embodiment is directed to use in a facility benefiting from the distribution of audio throughout different facility zones (“audio zones”), with each audio zone receiving an audio signal from a remotely-located audio distribution controller. For controlling audio at a user-controlled speaker load located in one of the audio zones, a circuit arrangement includes isolation circuit, speaker load circuit, user-input device and an audio control unit. The isolation circuit generates a transformed audio signal by provide an impedance-matched termination and by permitting one of a number of impedance-matching circuits to be set wherein each impedance-matching circuit provides a different amount of electrical power to the speaker load. The speaker load circuit delivers, in response to the transformed audio signal, audible signals in the audio zone. The audio control unit has a microprocessor adapted to control the delivery of the audible signals in response to the input commands generated via the user-input device.
