There are basically three types of equalizers: graphic, para-
metric, and a hybrid of these two, often referred to as paragraphic. Ad-
ditionally, there are passive equalizers, which have no gain, active gain
pre-amps, which have a again stage usually with a volume control, and
booster equalizers which we won’t consider here since they are inferior
passive equalizers with inexpensive IC amplier built-in.
As in state-of-the-art home audio systems the optimum system
requires a dedicated pre-amp with enormous gain to drive the various
power ampliers. Since home audio ampliers do not have adjust-
able sensitivity, they require a high output pre amplier to drive them to
maximum levels.
The unit is the rst production pre amplier to incorporate a
specic bandwidth parametric equalizer with shelving control with 18dB
boost or cut on its four bands, it can compensate for the four acoustic
anomalies unique to the automotive environment. This unit easily be-
comes the “Mission control Center” of any high end automotive sound
system.
