1. An electrotherapy system, comprising:
an electrotherapy device comprising:
a female port disposed on the electrotherapy device and configured to receive a male connector;
a subsystem configured to generate a first signal and a second signal having a frequency difference between 1 Hz and 300 Hz, wherein the first signal and the second signal have a base frequency of at least 200 Hz, and wherein the first signal and the second signal are linearly independent off phase alternating current signals that form a therapeutic signal;
class D switching amplifiers configured to amplify the first signal and the second signal, and configured to minimize a direct current (DC) component of the first signal and the second signal;
a feedback system configured to adjust the therapeutic signal based on an impedance change within a patient's body; and
a cable disposed between the male connector and two electrodes, wherein the two electrodes comprise a first electrode and a second electrode that are configured to be coupled to the patient's body, wherein the therapeutic signal is configured to reduce pain at a treatment site by sending a first signal from the first electrode to the second electrode and sending a second signal from the second electrode to the first electrode, and then simultaneously sending the first signal from the second electrode back to the first electrode and the second signal from the first electrode back to the second electrode.
