ABSTRACT:
An adaptor is connectable between a signal processor and a transmission module. The signal processor has three audio channels for feeding respectively a first audio signal, a second audio signal, and a third audio signal having a frequency range lower than a frequency range of the first and second audio signals. The transmission module has two transmission channels capable of transmitting two audio signals to a codeless speaker. The adaptor has three input terminals for receiving the first, second and third audio signals from the signal processor. The adaptor filters at least one of the first and second audio signals for cutting therefrom a lower frequency range comparative to the lower frequency range of the third audio signal, and adds the third audio signal to the one of the first and second audio signals from which the lower frequency range is cut. The adaptor has two output terminals, one of which feeds the one of the first and second audio signals added with the third audio signal to one of the two transmission channels of the transmission module, and the other of which feeds the other of the first and second audio signals to the other of the two transmission channels of the transmission module.
