The Epicenter Digital Bass Restoration Processor is designed to enhance the bass response of a vehicle's audio system by analyzing the audio signal, restoring missing bass tones, and increasing the overall bass output. The key function is to identify low-frequency information that may be lost during audio production or transmission and reintroduce it back into the audio signal path. This restoration process helps recreate deep bass tones that may not be adequately reproduced by subwoofers alone. The Epicenter also offers parametric bass control, allowing you to fine-tune the bass response. You can adjust parameters such as center frequency, bandwidth, and level to customize the bass output according to your personal taste. Also included is a subsonic filter, which helps eliminate very low-frequency content that could potentially cause distortion or strain by blocking frequencies below a cutoff point from reaching the subwoofers, resulting in cleaner and more efficient bass output
