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.
