Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
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 control how much
bass is restored to the system. A full range signal is output from the
Epicenter Plus that can feed a full range amp, a subwoofer amp (with built-in
crossover), or an outboard crossover.
Speaker Input: The speaker
level input is compatible with nearly any factory stereo system.
Auto Turn-on: The speaker
level input also has a signal sensing circuit; the unit turns on when there's a
speaker level input signal and turns off when the signal disappears.
Remote Output: The +12 volt
DC remote output will trigger an amp to turn on whenever the Epicenter Plus is
on. The remote's maximum current output is 1 amp.
There is a pair of RCA auxiliary input jacks on the unit so you can easily add
an iPod, satellite radio, or other secondary source. The aux input is engaged by
pressing the knob on the wired remote. Note: The auxiliary source must have its
own volume control; the Epicenter Plus has no way of controlling the volume.
Bass Maximization: The Bass
Maximization circuit allows The Epicenter Plus 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 7.5 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
Plus 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 Blocks: The power/ground/remote in/remote out
terminal and the speaker level input terminal are removable; the wiring is
attached to the block, then the block is plugged into the Epicenter Plus.
