An active monitor is a type of loudspeaker that has its own built-in power amplifiers and does not require an external amplifier to function. It is primarily used in professional audio applications, such as music production, broadcasting, and sound reinforcement. Synonyms for an active monitor include powered monitor, self-powered monitor, and active speaker. These terms are interchangeable and describe the same type of speaker. Active monitors are preferred over passive monitors because they eliminate the need for a separate amplifier, resulting in a more streamlined setup and superior audio quality. They also provide greater control over sound shaping and equalization.
