Electrical device that is used for
adjusting
sound. Often referred to as EQ. The cheap EQs only let you adjust
bass and
treble, while the most common ones (and the more expensive ones) let you adjust all frequencies.
EQs became popular in
sound engineering during the 50s. Today EQs are used EVERYWHERE where there is a
concert,
theatre, or anything else that requires sound engineering. EQs allow the
technicians to decrease the
volume of
frequencies that have ugly sounds, while increasing others. EQs are also good for preventing
feedback by lowering the threatening
frequencies.
Today we have both
analogue and
digital EQs. Digital EQs have the advantage of being smaller by having multiple
lines connected to one
control. The downside with digital EQs is that its easier to mess things up, since you sometimes adjust the wrong line.
Electrical components such as
TVs,
amplifiers,
mixers, and
CD players usually have at least one built-in EQ.
