Impedance is an electronics term which measures the amount of opposition a device has to an AC current (such as an audio signal). Technically speaking, it is the combined effect of capacitance, inductance, and resistance on a signal.
LOW impedance is better than HIGH impedance. Low is usually associated with Professional Mics,High, with amateur Mics
