EQUALIZER BACKGROUND

There are basically three types of equalizers: graphic, parametric and a
hybrid of these two,often referred to as paragraphic. Additionally, there are
passive equalizers, which have no gain, active gain preamps, which have a
gain stage usually with a volume control, and booster equalizers which we
won,t consider here since they are inferior passive equalizers with
inexpensive IC amplifiers built-in.

As in state-of-the-art home audio systems the optimum system requires a
dedicated preamp with enormous gain to drive the various power amplifiers.
Since home audio amplifiers do not have adjustable sensitivity, the require a
high output preamplifier to drive them to maximum levels.

This unit is the first production preamplifier to incorporate a specific
bandwidth parametric equalizer with shelving control. With 18dB boost or
cut on its four bands, it can compensate for acoustic anomalies unique
to the automotive environment. The Vibe 440PSU easily becomes the
Control Center of any high-end mobile entertainment system.
