7. GLOSSARY
Crossover: A device that limits the range of frequencies sent to a speaker or amplifier.
Equalization: the process of boosting or cutting sound signal frequencies to improve the
quality of the sound. The term comes from the filters used to add back high frequencies at
the receiving end of analog transmissions over wires.
Equalization band: the frequency range impacted by a specific filter.
dB: decibel, a measurement of the relative difference in power or intensity between two
acoustic signals
Gain control: gain is the amount of amplification (voltage, current or power) of an audio
signal expressed in dB
Graphic equalizer: a multi-band variable equalizer that uses mechanical controls to
adjust amplitude.
Hz: Abbreviation for Hertz, a unit of frequency equal to one cycle per second.
Octave: the musical principle of dividing sound frequencies into the eight notes of the
musical scale.
OEM: Original Equipment Manufacturer
RCA input/output: port through which sound travels in and out of the system; “RCA”
refers to the type of connector, which was originally manufactured by Radio Corporation
of America.
Slope: how fast the sound changes rated in dBs. The higher the dB number, the faster
the frequency drops off.
