Dummy load

A high-power resistor that is connected to the output of a power amplifier to make the amplifier function as though it had a loudspeaker connected to it. A dummy load circuit can be used to test amplifier performance as it would perform when connected to loudspeakers, or in a device such as a speaker simulator so that the amplifier always sees a high-impedance load at the output stage, even if no loudspeaker is connected.
