These amplifiers typically feature multiple channels, allowing musicians to connect various instruments simultaneously. They provide a clear and powerful sound, making them ideal for practice sessions, live performances, and studio recordings. Most keyboard amplifiers come with built-in speakers and may include effects like reverb or chorus to enrich the sound. They are often portable, making them convenient for musicians on the go.
