Active soundbars are soundbars that have their own built-in amplifier and do not require an external amplifier to function. They also have digital signal processing (DSP), source inputs, and volume control. This means that they can produce sound directly from your TV without the need for additional equipment. All you have to do is plug them in and enjoy the powerful sound they deliver. Active soundbars are convenient and easy to use, making them a popular choice for enhancing the audio experience of your TV. They eliminate the need for separate amplifiers and offer a compact and streamlined solution for better sound quality. With their all-in-one design, active soundbars provide an immersive audio experience without the hassle of complex setups.
