INTRODUCTION
The Bass Accelerator is a bass restoration signal processor with a remote gain control. Think of it as an
electronic subwoofer turbo-charger for your system! The Bass Accelerator identifies and restores the low
frequencies mixed down or filtered out during the normal recording process.
Since the acoustics and speaker placements of each vehicle are different, the Bass Accelerator is
equipped with a set of frequency and bandwidth (Q) controls to fine tune and compensate for possible
bass deficiencies. For hands on control of the amount of bass restoration, a dash mount wired remote
gain control is included.
