What Is Output Impedance?

- Jul 02, 2018-

The output impedance is the internal resistance of the input. In the audio system, the output impedance of the power amplifier should be equal to the impedance of the speaker to obtain the maximum and optimal power output; when the system is mated, the output impedance of the preamplifier should be much smaller than the input impedance of the post device, so as to ensure It is not affected by the connection of the downstream equipment, so the output impedance of the rescue equipment should be as small as possible.
