Audio Control Epicenter Bass restoration processor (EPICENTER)
You like all the bumpin' bass you hear in hip hop, rap, and EDM? Well you can put that deep, biting bass into any kind of music — from classical, jazz, and rock to folk and Tejano — with an AudioControl Epicenter bass restoration processor. Most factory radios dial down bass response to protect flimsy speakers, so when you do add a subwoofer, there's no bass to play. The Epicenter will bring it back.

AudioControl's legendary Epicenter bass processor maximizes the low-frequency power and punch of your bass system, whether it's a simple powered bass tube or a full-blown competition setup. Simply install this processor between your receiver and your amplifiers or crossovers, and you'll finally be able to hear all the good bass you've been missing. An included wired remote lets you control the amount of thump from the front seat.
How does it do it?
Sophisticated processing analyzes the incoming signal and synthesizes low-bass fundamental tones, increasing bass response tremendously. The Epicenter connects to any receiver with preamp outputs — its balanced inputs will reject noise from your car's electrical system. A subsonic filter removes extreme low frequencies from your signal so your amps and subs will play more efficiently, while a single band ParaBass equalizer lets you fine-tune the bass tone.
Bass Restoration: Rather than simply turning up the bass, the patented bass restoration circuit takes a full range input signal and measures the upper harmonics of the bass frequency range to determine what frequencies have been lost during the recording process, then correctly restores the missing bass information. The remote rotary knob allows you to control how much bass is restored to the system. A full range signal is output from the Epicenter that can feed a full range amp, a subwoofer amp (with built-in crossover), or an outboard crossover.
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.
Bass Maximization: The Bass Maximization circuit allows The Epicenter to maximize the bass output of any system while restraining destructive bursts, which can damage speakers. the 5.0 volt factory setting can be changed to 2.5, 7.5, or 10 volts if the amplifier and speakers can handle it.
Remote: The bass restoration level is adjusted using the included wired remote. The remote is designed to be dash mounted, within reach of the driver; it can be mounted under the dash with the supplied bracket, or the bracket can be removed and the knob and LED can be custom mounted through the dash. Dimensions:
- Width: 2.557"
- Height: 1.489"
- Depth: 1.824" (2.448" including knob)
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.
Balanced Inputs: Using the balanced differential input circuit cancels noise picked up in the transmission line between the Epicenter and the the source unit. The inputs can be set to balanced or unbalanced if needed.
Ground Isolation: The power supply ground is switchable, in case of ground loop noise. The factory position is fully isolated (typically the best choice), but can be changed to Ground or 200Ω.
Terminal Block: The power/ground/remote terminal is removable; the wiring is attached to the block, then the block is plugged into the Epicenter.
