Abstract: Disclosed is an amplifying connector. The amplifying connector comprises (a) a connector body; (b) an op amp forming an amplifier mounted to the connector body; (c) a power supply circuit mounted to the connector body and coupled to the amplifier; (d) a connector output on the connector body coupled to an amplifier output of the amplifier; and (e) a connector input on the connector body coupled to an amplifier input of the amplifier. An input electrical signal on the connector input is buffered by the amplifier to generate an output electrical signal on the connector output to reduce effects caused by an impedance of the cable. The amplifier may be powered by a power supply circuit powers that draws a portion of the current or voltage from the input signal of a source electronic device, or by an on-board dedicated low power battery power supply.
