The Epicenter Micro combines AudioControl’s legendary digital bass restoration with world-renowned OEM integration capabilities. Featuring a speaker-level input stage with selectable impedance loads, as well as traditional line-level inputs, The Epicenter Micro brings out the best bass in any system. Trigger modes include traditional +12V remote in, GTO™ Signal Sense, and Audio Sense. The PFM Subsonic Filter can be bypassed for the truly dedicated, and the 10V+ output voltage setting beckons only the bravest among us. Use the included ACR-4 remote to independently adjust bass restoration and output level.

Bass Maximizer

The Epicenter® Micro is designed to reproduce low-frequency information by looking at the upper-frequency ranges and detecting musical harmonics. These harmonics then allow The Epicenter® Micro to drop down a few octaves and reproduce the “missing” bass notes.

Line Output Converter

Beyond maximizing bass, The Epicenter® Micro is a line output converter packed with premier OEM integration features like AudioControl’s Load Matching Circuit (LMC) with Load Select, multiple Trigger Modes, and selectable Ground Isolation. For power-users, the PFM Subsonic Filter can be bypassed and Output Voltage can be configured for up to 10 Volts!
