Abstract (en)

[origin: EP2389011A2] An audio system (1000) comprises an audio control unit (1002) and a speaker unit (1020, 1030, 1040). The audio control unit receives an external power signal (1016) and an audio input signal (1012, 1013, 1014, 1015), and outputs a variable power supply signal (1025, 1035, 1045) and an audio speaker signal (1024, 1034, 1044) to the speaker unit via at least one low power cable. The speaker unit comprises a local output amplifier (1021, 1031, 1041) and at least one drive unit. The local output amplifier is powered by the variable power supply signal and amplifies the audio speaker signal for the drive unit.
