Main highlights

• •Bass Restoration Processor, Included ACR-1 Remote Level Control & 20' RJ-14 Cable
• •Enhanced bass output: The device restores low-end frequencies and provides a more dynamic and immersive listening experience.
• •Built-in bass maximization circuit: The circuit allows you to adjust the frequency response and control the level of the bass output.
• •Remote bass level control: The remote control allows you to adjust the bass output from the comfort of your driver's seat.
• •Advanced processing technology: The device is designed with advanced signal processing algorithms and a variable bass boost control for customized bass response.
• •Para-Bass: Para-Bass is a single band, parametric equalizer for the bass output. The center frequency is continuously variable from 27 Hz to 63 Hz. The width of the band is also adjustable.
• •Subsonic Filter: The subsonic filter crossover point is 33 Hz; it's governed by a replaceable chip, so it can be changed to 20, 25, 30, 35, 40, or 45 Hz.
• •EPICENTER LINK: Seamlessly connect the EPICENTER bass restoration processor with an EPIC Monoblock or 5-channel amplifier for an unbeatable audio experience and 1A fuse protection to safeguard your equipment.
