Abstract
An audio cable connector with selectable impedance includes low impedance interface circuitry and high impedance interface circuitry, and a user-operable switch to allow a user to select either of the two impedances to connect to a headset microphone. With the audio cable connector in communication between a headset and equipment, the user may select the appropriate impedance interface circuitry to allow the headset to operate properly with the equipment.
Claims20
An audio cable connector with selectable impedance, comprising:
- a cable comprising a plurality of wires configured to connect to a communications headset;
- a plug configured to connect to a communications device;
- a housing configured to contain logic and control circuitry;
- logic and control circuitry positioned within the housing and operable to receive input from a user and to connect impedance matching circuitry between a microphone input from the cable and the plug, the logic and control circuitry comprising:
- first impedance matching circuitry comprising a low impedance interface;
- second impedance matching circuitry comprising a high impedance interface;
- and
- a switch operable to cause the logic and control circuitry to select one of the first impedance matching circuitry or the second impedance matching circuitry for connection to the microphone input upon actuation of the switch by a user.
