Product Highlights


  • 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 through the recording process, streaming algorithms, or other processes, then correctly restores the missing bass information. The two remote rotary knobs allow you to control how much bass is restored to the system and the output level. A full-range signal from the Epicenter can feed a full-range amp, a subwoofer amp (with built-in crossover), an outboard crossover, or DSP.

  • 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.

  • ParaBASS: single band parametric equalizer for the bass output
    • Wide: width of the parametric band is adjustable
    • Sweep: center frequency continuously variable 27-63 Hz (45 Hz in the middle)

  • Load Select: set speaker level input load
    • 20Ω: typically used with factory systems that have no amplifier (base system)
    • 60Ω: typically used with factory systems having a separate amplifier (premium system)
    • 20 kΩ: used for all other applications

  • Balanced Inputs: a balanced differential input circuit cancels noise picked up in the input transmission line; jumpers inside the chassis can be changed to unbalanced if needed

  • Trigger Mode: set how the Epicenter is turned on
    • Remote: turns on with +12 volts on the remote in terminal
    • GTO: (Great Turn On) turns on with the factory amplifier
    • Audio: turns on when an audio signal is sensed at the input; speaker level or line level

  • Ground Isolation: 3-position switch for power supply ground; Ground, ISO, 200Ω; best setting is typically the default ISO (fully isolated), but if you have noise try the other settings

  • PFM Subsonic Filter:
    • On: removes frequencies below 20 Hz
    • Off: filter is bypassed, generally a bad idea, particularly with ported sub enclosures

  • Output Voltage: set the maximum output voltage to match downstream processor/amp(s); 5 volts, 7.5 volts, 10+ volts

  • Remote: The wired remote has two concentric knobs; the outer knob controls the bass restoration level and the center knob controls the overall output level (volume). 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.
