Active monitors are speakers that have built-in amplifiers and are designed for professional audio production. They provide accurate sound reproduction, making them ideal for mixing and mastering music. Unlike passive monitors, which require an external amplifier, active monitors simplify setup and ensure consistent performance. These monitors often include features like adjustable EQ settings and multiple input options, allowing users to tailor the sound to their environment. Popular brands include Yamaha, KRK, and JBL, each offering various models to suit different needs and budgets. Active monitors are essential tools for musicians, producers, and sound engineers.
