3.12 Should I buy an equalizer? [JSC]
Equalizers are normally used to fine-tune a system, and should be treated as such. Equalizers should not be purchased to boost one band 12dB and to cut another band 12dB and so on - excessive equalization is indicative of more serious system problems that should not simply be masked with an EQ. However, if you need to do some minor tweaking, an EQ can be a valuable tool. Additionally, some EQs have spectrum analyzers built in, which makes for some extra flash in a system. There are two main kinds of EQs available today: dash and trunk. Dash EQs are designed to be installed in the passenger compartment of a car, near the head unit. They typically have the adjustments for anywhere from five to eleven (sometimes more) bands on the front panel. Trunk EQs are designed to be adjusted once and then stashed away. These types of EQs usually have many bands (sometimes as many as thirty). Both types sometimes also have crossovers built in.
