Description:

This equalizer is a high fidelity audio control that automatically adjusts the bandwidth or "Q" as you change frequencies. The built-in preamplifier stage raises the signal level of your head unit and increases the dynamic range of your system. PWM Power Supply provides steady voltage from the vehicle's charging system which can vary under normal driving conditions. Fader control allows easy balancing between the front and rear speakers when used with separate amplifiers for the front and rear channels. Retractable control knobs allow you to adjust your settings and then "push in" to prevent accidental movement.
