Graphic (equalizer) - Refers to a type of equalizer with sliding controls that
create a pattern representing a graph of frequency response changes.
Ground - An electrical line with the same electrical potential as the chassis
of the vehicle, most commonly negative 12 volts DC.
Ground Loop - The condition created when two or more paths for
electricity are created in a ground line, or when one or more paths are created in
a shield or an audio cable. This can create undesirable noise such as a high pitched
whine when the vehicle is running or pops and clicks when other devices are used in
the vehicle.
Ground Potential - In an automobile this is the electrical potential of the
vehicles chassis. A circuit, terminal or chassis is said to be at ground potential when
it is used as a reference point for other potentials in the system.
