Question Mark Icon of Question Mark
This determines the way the equalizer processes the signal from the source unit. A parametric equalizer allows to you adjust the center point of the frequency band you are adjusting as well the bandwidth which can be narrowed or widened. A graphic equalizer has fixed frequency bands and bandwidth and only the frequency bands can be adjusted. A digital equalizer uses a software program to tune your system.
A graphic equalizer typically has more adjustable bands and is less expensive, whereas a parametric will have fewer bands but offer a greater level of control and provide more tuning options. Digital equalizers will tune your system with the most detail and precision but require a computer and are typically a little higher in price.

A line driver is a small amplifier used to support the strength of the audio signal coming from the source unit.
