Soundstorm SSL 4 Band Pre Amp Graphic Car Audio Stereo Equalizer EQ (10 Pack)

This S4EQ Equalizer from Soundstorm Laboratories (SSL) is a 4 band Pre-Amp Equalizer for your car audio needs. It includes EQ Bands of 40Hz, 150Hz, 1khz, 20kHz with a dual 2 Ch source input. It also includes front, rear and sub outputs. This package contains 10 equalizers. It includes built-in crossovers that enable you to tailor the audio to your system’s needs. A high-pass filter allows only the frequencies above the set frequency to pass through to your full range or component speakers and a low-pass filter allows only the frequencies below the set frequency to pass through to your subwoofers so your speakers and subwoofers can perform more efficiently and effectively. The phase control feature allows you to adjust the speakers phase to ensure all audio signals are playing together rather than against each other. When bass notes are noticeably absent, a quick and easy adjustment to the phase control could provide the perfect remedy.
