1. An audio processor, comprising:

  • an audio processor;

    a number of audio input circuits and a number of audio output circuits; and

    a number of ports, wherein at least one of the ports is bi-directional and is configurable to supply signals to or receive signals from the audio processor, wherein the at least one bi-directional port includes;

    an audio connector;

    an audio input circuit that is electrically coupled lo the audio connector; and

    an audio output circuit that is electrically coupled to the audio connector via a low impedance path through a switch in a conducting state;

    wherein the switch is bypassed with a resistor when the switch is in a non-conducting state such that the audio cutout circuit is electrically coupled to the audio connector through a higher impedance of the resistor.
