7. GLOSSARY
Crossover: A device that limits the range of frequencies sent to a speaker or amplifier.
dB: decibel, a measurement of the relative difference in power or intensity between two acoustic signals.
Equalizer: Component that boosts or cuts sound signal frequencies to improve the quality of the sound.
Gain control: gain is the amount of amplification (voltage, current or power) of an audio signal expressed in dB.
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.
Ohm: unit of electric resistance
RCA input/output: port through which sound travels in and out of the system; “RCA” refers to the type of connector, which was first manufactured by the Radio Corporation of America.
Slope: how fast the sound gets quieter rated in dBs. The higher the dB number, the faster the frequency drops off.
