Abstract
An audio processor has a number of ports that are configurable as input or output ports. Each port includes a jack, an input audio circuit and an output audio circuit. A switch is controllable to selectively connect an output of the output audio circuit to the jack when the port is configured as an output port. In one embodiment, the switch is bypassed with resistor and the output of the output audio circuit is coupled through the resistor to the jack when the port is configured as an input port.
Claims17
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.
