7. GLOSSARY
8. SPECIFICATIONS
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.
Note:
The technical data and the design of the equipment may change without
prior notice for the sake of technical improvements.
