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.
