摘要

The equipment i.e. amplification/emission unit (3), has a audio/video amplifier (9) for providing a set of signals of audio outlets in output, and input units for providing an electrical signal in an input of the amplifier, where the signals include a low signal, central outlet signal, right front and rear outlet signal and left front and rear outlet signals. An electrical connection unit provides the set of signals of the audio outlets in an input of a set of wireless transmitters (10a- 10n), where the set of transmitters emits power of 0.5 to 1 watts.
