HOW AN EQUALIZER IS USED

The Sound Storm S4EQ graphic equalizer is a high-Fidelity signal processor/preamplifier that allows you to graphically view and individually control a number of different frequency bands in a stereophonic system. It is intended for use in a car audio system which includes amplifiers in a signal path AFTER the equalizer, and provides front, rear and subwoofer low level outputs via RCA connectors.
