Bass Restoration: The Epicenter detects bass harmonics, then digitally recreates the underlying fundamental for the incredible punch and impact of live music. 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. 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 source unit. The inputs can be set to balanced or unbalanced if needed. 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. 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.
