Studio monitors are specifically designed for applications where accurate reproduction of sound is essential to the production and mixing process. The output from studio monitors is often different from consumer-grade audio speakers, which can further color the sound. The accuracy of studio monitors is crucial for performers and audio engineers to achieve the desired result. An active (or powered) studio monitor includes a built-in amplifier, so the monitor can be directly connected to a line level source. Active studio monitors save space and time because, unlike passive monitors, there is no need for specific external equipment to get the active monitor to function.
