low impedance (Lo-Z)
The term low impedance refers to the input or output impedance of an electronic component, actuator, sensor, or electronic circuit.
Low impedance states that the impedance of the input or output circuit falls below a certain ohm value. As a rule, one speaks of low impedance, also referred to as Lo-Z in audio technology, when the impedance has a one- or two- digit ohm value.
Examples of low impedance components are cables - data cables, audio and video cables, connectors, high frequency cables - dynamic microphones, loudspeakers, antennas and the output impedance of power amplifiers. Impedance values above 10 kilo ohms to the tera ohm range are referred to as high impedance.
