AudioControl EPICENTER PRO Bass Restoration Processor & Line Driver
If the subwoofer system has enough power but the music itself is missing the low bass that should be there, adding more gain or EQ is not the same as restoring that content. The EPICENTER PRO is built specifically for that job. It analyzes upper-bass harmonics, recreates the missing fundamental bass information, and puts that restored low-frequency content back into the signal path.
The PRO version is the right fit when the system already has a clean line-level signal. It combines AudioControl bass restoration with ParaBASS shaping, balanced line-level inputs and a high-voltage line driver. Compared with the EPICENTER Micro PRO, it does not add speaker-level OEM-integration inputs or selectable input-load settings.

What’s in the Box
EPICENTER PRO processor, ACR-4 dual-knob remote, remote cable and user guide.
Good fit: aftermarket or integrated systems that already provide a clean RCA/preamp-level signal and need bass restoration plus line driving. Need speaker-level factory-radio integration in the processor itself? Use the EPICENTER Micro PRO instead.
Where this fits in the build
This is a system-control or DSP component. The correct choice depends on the signal path, channel count, routing, retained features and the rest of the amplifier and speaker plan.
